RE: 1028 NE Alberta St
Design for a static pressure of 49 psi (80% of nomin al max static pressure). Assume 1283 gpm is available at 39 psi (80% of nomi nal max static pressure minus observed drop at monitor hydrant).
Flow Test Results Flow Test ID #: 937 Map #: 2531 Date of 2/3/2004 Monitor Hydrant Port Info: Total Flow (gpm): 1283 Monitor Hydrant: NE Alberta St wwl 13th Ave Max Static HGL (ft): 362 Static Pressure (psi): 60 Hydrant Elevation (ft): 221 Residual Pressure 50 Nominal Max Static Pressure 61 Observed Drop (psi): 10
Flow Hydrant(s) Hydrant Location: NE Alberta St wwl 12th Ave Port 1 Size (in): 2 1/2" Port 1 Pitot Reading (psi): 16 Port 2 Size (in): 2 1/2" Port 2 Pitot Reading (psi): 13 Elevation (ft): 220 Main Size (in): 6 Flow (gpm): 1283
This test is a snapshot of system performance. Flow and pressure are affected by a variety of factors including: tank and reservoir levels, pump and valve settings, demand variations, and future changes to operational settings. The static pressure at this location may be as low as 80% of the maximum static pressure as calculated using the Max Static HGL.

1. DESCRIPTIONThe Viking Model F-2 Dry Pipe Valve is a latching differential valve used to separate the water supply
from the dry pipe sprinkler system. The valve combines a positive latching clapper and air plate assem-
bly, with a differential air to water seat design. The latching clapper and air plate assembly provides a
positive mechanical seal for the air pressure in the dry pipe system. The differential design allows an air
supply of moderate pressure to control a higher water supply pressure. When the air pressure in the dry
pipe system is lowered suffi ciently to destroy the pressure differential, the valve opens allowing water
to enter the dry pipe system.
The valve is also designed to operate a water motor alarm and/or an electric pressure alarm switch.
The Viking accelerator with external Anti-fl ood Device can be used to speed the operation of the valve
on large capacity systems or where faster action is required.

4. INSTALLATION For proper operation and approval, the valve must be trimmed in accordance with Viking Model F Dry Valve Trim Charts.
The Model F-2 Dry Valve must be installed in the vertical position as shown in Figure 2.
Air or nitrogen supply to the dry pipe system must be clean, dry, and oil free.
Automatic air supplies must be regulated, restricted, and from a continuous source. (Refer to Table 2) A Viking Air Maintenance Device
should be installed on each system equipped with an automatic air supply. Never exceed 60 PSI (4.1 bar) pressure in the system pip-
ing with the dry valve clapper closed.
The dry valve must be installed in an area not subject to freezing temperatures or physical damage. If required, provide a valve house
(enclosure) with adequate heat around the dry valve and trim. Freezing temperatures and/or excessive pressure will damage the dry
valve member assembly.
When corrosive atmospheres and/or contaminated water supplies are present, it is the owner’s responsibility to verify compatibility
with the Model F-2 Dry Valve and associated equipment.
Consider installation of the Viking Accelerator and Anti-fl ood Device. An accelerator (quick opening device) is recommended on all
differential dry pipe valves and is required on dry pipe systems of certain capacities. Refer to Installation Standards and Authorities
Having Jurisdiction. If an accelerator is to be installed, verify that the appropriate Trim Chart is used. Prior to installing the valve, thor-
oughly fl ush the water supply piping to verify that no foreign matter is present.
A. General Installation InstructionsVerify that necessary Trim Charts and Technical Data for the dry valve and associated equipment are available.
Remove all plastic thread protectors from the openings of the dry valve.
Apply a small amount of pipe-joint compound or tape to the external threads of all pipe connections required. Take care not
to allow any compound, tape, or other foreign matter inside any of the nipples or openings of the dry valve or trim compo-
nents.
Install the Model F-2 Dry Valve and trim piping according to the current Model F-2 Dry Valve Trim Chart provided with the
Trim Package and the Viking Engineering and Design Data book. The Model F-2 Dry Valve must be installed in the vertical
position.
When installing a Viking Accelerator and Anti-flood Device in conjunction with the Model F-2 Dry Valve, refer to the appropri-
ate Viking E-1 Accelerator Trim Chart provided with the Accelerator Trim Package and the Viking Engineering and Design
Data book.
When a Viking Accelerator is installed on the Model F-2 Dry Valve, the dry system air supply must be connected as shown
on the Model E-1 Accelerator Trim Chart.
The Viking external Anti-flood Device is required when a Viking Accelerator is installed on a Dry Valve according to the
Model E-1 Accelerator Trim Chart.
Hydrostatic Test:CAUTION: THE DRY VALVE CLAPPER MUST BE LATCHED OPEN DURING PERFORMANCE OF THE HYDROSTATIC TEST.
Do not perform a 200 PSI (13.8 bar) hydrostatic system test with the dry valve clapper in the closed (set) position.
Never exceed 60 PSI (4.1 bar) air pressure in the system piping with the dry valve clapper closed.
DO NOT expose the Viking Accelerator to the hydrostatic test. For warnings and considerations regarding hydrostatic testing of the
Viking Accelerator and other system components, refer to Technical Data for the equipment used.

When the dry pipe system is ready to be placed in service, verify that all equipment is adequately heated and protected to prevent
freezing and physical damage.
Verify that the water supply main control valve supplying the dry valve is closed.
Open the main drain valve (located on the inlet of the dry valve).
Drain all water from the dry pipe system. If the system has operated, or if water has entered the system, open all auxiliary
drains and the system test valve. Allow enough time to completely drain the system. Perform steps 4 through 10 to set the
dry valve and/or inspect the internal operating parts of the dry valve.
Verify that the dry pipe system is not pressurized.
Use the Dry Valve Reset Bar/Wrench, part number 02977BM, to loosen and remove hand-hole cover bolts (21). Remove
hand-hole cover (24).
CAUTION: CLAPPER ARM ASSEMBLY (8) AND CLAPPER ASSEMBLY (5) ARE SPRING LOADED TO OPEN. NEVER PLACE HANDS INSIDE THE DRY VALVE IF THE CLAPPER ASSEMBLY IS LATCHED CLOSED.
To release a latched clapper assembly for service:
Insert the re-setting tool through the hole in hook assembly (15), across the fulcrum cast on top of clapper arm assembly
(8) until the re-setting tool contacts the stopping boss on top of clapper arm assembly (8) (see Figure 2C).
Apply a downward force on the end (outside the valve) of the re-setting tool. Hook assembly (15) will slide toward the hand-
hole and off clapper arm assembly (8). Clapper arm assembly (8) and clapper assembly (5) will forcefully open, impact
against latch (2), and latch in the open position.
NOTE: INSPECTION AND CLEANING PROCEDURE STEP 7 BELOW IS CONSIDERED PART OF THE ANNUAL TRIP TEST.
Inspect and clean the internal parts of the valve. Give special consideration to the water seat (16), air seat (20) and clapper
rubber (19). Wipe away all contaminants, dirt, and mineral deposits. Do not use solvents or abrasives. Operate all parts to
test freedom of movement. Renew or replace damaged or worn parts as required.
CAUTION: NEVER APPLY ANY LUBRICANT TO SEATS, GASKETS, OR ANY INTERNAL OPERATING PARTS OF THE DRY VALVE. PETROLEUM BASED GREASE OR OIL WILL DAMAGE RUBBER COMPONENTS AND MAY PREVENT PROPER OPERATION OF THE DRY VALVE.
To set the dry valve clapper. (Refer to figures 2 & 3)
Raise the latch (2) to release spring loaded clapper arm assembly (8) from the latched open position.
Move the clapper arm assembly (8) down toward the horizontal position (see Figure
2-B).
While holding spring loaded clapper arm assembly (8) down, insert the re-setting
tool through the hole in hook assembly (15), across the fulcrum cast on top of clap-
per arm assembly (8) until the re-setting tool contacts the stopping boss as shown
in Figure 2-C.
Apply a sharp upward force at the end of the re-setting tool. Hook (15) will slide
forward on the re-setting bar and latch the clapper closed with a positive setting
action (see Figure 2-C).
Priming water is not required and may not be desirable where clean, good quality fresh
water is not available. If priming water is desired, fill the dry valve with water to the bot-
tom of the hand-hole. Verify that the intermediate chamber of the dry valve is free of
water. No water should fl ow from the drip check when the plunger is pushed.

Visually inspect hand-hole cover gasket (25). Verify that it is in good condition.
Re-install hand-hole cover (24), gasket (25), and hand-hole cover bolts (21). Tighten the bolts using the Dry Valve Reset
Bar/Wrench, part number 02977BM.
Close all auxiliary drains, the system test valve, and the priming water level test valve on the dry valve trim. The main drain
(located on the inlet of the dry valve) should remain open.
If equipped with a Viking Accelerator and external Anti-flood Device:
Close the ½” (15 mm) anti-flood isolation valve.
Observe the air pressure gauge on top of the accelerator. The gauge must read zero before the accelerator will auto-
matically reset. It may be necessary to loosen, remove, and re-install (use the appropriate wrench) the air gauge to vent
trapped air pressure from the upper chamber.
Open the dry system air supply and establish desired system pressure. See Table 2 for suggested air pressure to water pres-
sure settings. NEVER EXCEED 60 PSI (4.1 bar) AIR PRESSURE.
Verify that the intermediate chamber of the dry valve is free of water. No water should flow from the drip check when the
plunger is pushed.
If equipped with a Viking Accelerator and external Anti-flood Device: When pressure on the accelerator air pressure gauge
equals the system set pressure, OPEN and secure the ½” (15 mm) anti-flood isolation valve.
Slowly open the water supply main control valve.
When flow is developed from the main drain, CLOSE the main drain valve.
Fully open the water supply main control valve.
Secure all valves in their normal operating position.
Notify Authorities Having Jurisdiction and those in the affected area that the system is in service.
5. OPERATION (Refer to Figure 2)
The clapper (5) and air plate (11) assemblies combine to form a fl oating member assembly. With the clapper assembly (5) latched
closed, system air pressure forces the member assembly down, sealing the water seat (16) from the intermediate chamber. When
a sprinkler operates, the system air pressure is reduced. When system air pressure is reduced to the differential tripping point of the
valve, water supply pressure in the inlet chamber lifts the member assembly off the water seat (16) and fl ows into the intermediate
chamber. As the member assembly continues to rise, the latching hook (15) is forced against operating pin (23), which causes the
hook (15) to pivot on hook rod (6b) and unlatch the clapper. The clapper is spring loaded and swings to a full-open locked position
(See Figure 2-A).
When equipped with the optional Accelerator and external Anti-fl ood Device, a drop in system air pressure causes the Accelerator to
operate. Operation of the Accelerator causes the Anti-fl ood Device to open allowing system air pressure to enter the dry valve interme-
diate chamber. This immediately destroys the pressure differential, causing the member assembly to rise faster.
The intermediate chamber is normally at atmospheric pressure and is connected to the alarm line. When the valve trips, the intermedi-
ate chamber and alarm line are pressurized with system water pressure, activating alarms connected to the dry valve trim.
ABNORMAL CONDITIONSSee Table 3
6. INSPECTIONS, TESTS AND MAINTENANCENOTICE: THE OWNER IS RESPONSIBLE FOR MAINTAINING THE FIRE PROTECTION SYSTEM AND DEVICES IN PROPER OPERAT-ING CONDITION.
The Viking Model F-2 Dry Valve and trim must be kept free of foreign matter, freezing conditions, corrosive atmospheres, contaminated
water supplies, and any condition that could impair its operation or damage the device.
It is imperative that the system be inspected and tested on a regular basis. The frequency of the inspections may vary due to con-
taminated water supplies, corrosive water supplies, corrosive atmospheres, as well as the condition of the air supply to the system.
For minimum maintenance and inspection requirements, refer to NFPA 25. In addition, the Authority Having Jurisdiction may have
additional maintenance, testing, and inspection requirements that must be followed.
WARNING: ANY SYSTEM MAINTENANCE WHICH INVOLVES PLACING A CONTROL VALVE OR DETECTION SYSTEM OUT OF SER-VICE MAY ELIMINATE THE FIRE PROTECTION CAPABILITIES OF THAT SYSTEM. PRIOR TO PROCEEDING, NOTIFY ALL AUTHORI-TIES HAVING JURISDICTION. CONSIDERATION SHOULD BE GIVEN TO EMPLOYMENT OF A FIRE PATROL IN THE AFFECTED AR-EAS.
I. INSPECTIONWeekly inspection is recommended. If the system is equipped with a low air (or nitrogen) alarm, monthly inspections may be ad-
equate.

Compare test results with previous flow information. If deterioration of the water supply is detected, take appropriate steps to
restore adequate water supply.
Verify that normal water supply pressure and system pneumatic pressure have been restored, and that all alarm devices and
valves are secured in normal operating position.
Notify the Authority Having Jurisdiction that the test is complete. Record and/or provide notification of test results as required
by the Authority Having Jurisdiction.
C: Priming Water Level, and Low Air Alarm TestQuarterly testing is recommended to verify that water is not present above the Priming Level Test Valve in the dry valve trim.
Quarterly testing of low air alarms is recommended.
Notify the Authority Having Jurisdiction and those in the area affected by the test.
Fully open the main drain (located on the base of the dry valve) to flush away any accumulation of foreign material.
Close the main drain.
Close the water supply Main Control Valve supplying the dry valve.
Open the Main Drain Valve (located on the inlet of the dry valve).
If the dry valve being tested is equipped with a Viking Accelerator and external Anti-fl ood Device installed according to Viking Model
E-1 Accelerator Trim Charts, performing steps 6 or 7 of this test will cause the accelerator to operate. A burst of air from the vent in the
bottom of the accelerator will indicate operation of the accelerator. However, with the water supply Main Control Valve CLOSED and
the Main Drain Valve OPEN, operation of the accelerator should not trip the dry valve.
Dry Valve Priming Water Level Test:
Verify that the water supply main control valve is closed and the main drain valve is open.
Fully open the Priming Level Test Valve in the dry valve trim to check for the presence of water. If the presence of water
is detected, the system may not have been properly drained. Perform steps 1 through 3, and 11 through 15 of paragraph
10, PLACING DRY VALVE IN SERVICE, and repeat this Dry Valve Priming Water Level Test.
If/when no water is detected and the test is complete, continue to step 8.
Low Air Alarm Test:
Verify that the water supply main control valve is closed and the main drain valve is open.
Gradually open the Priming Level Test Valve in the trim of the dry valve to simulate operation of the Dry System. Observe
and record the pressure at which the low air alarm operates.
Close the Priming Level Test Valve.
If the dry valve being tested is equipped with a Viking Accelerator and external Anti-flood Device:
Close the ½” (15 mm) NPT Anti-flood Isolation Valve. Air will continue to flow from the accelerator after it has operated
until step “b” below is performed.
Loosen (use the appropriate wrench), and remove the Accelerator Air Gauge to release pressure from the upper chamber
of the accelerator. When the accelerator re-sets, re-install the accelerator air gauge.
Perform steps 13 through 20 of paragraph 4-B INSTALLATION, Placing the Valve in Service.
TRIP TESTSPartial Flow Trip Tests are conducted with the water supply main control valve partially closed to minimize the amount of water enter-
ing the system during the test. Performance of a Partial Flow Trip Test is recommended during warm weather at least annually except
when a Full Flow Trip Test is conducted. Partial Flow Trip Tests may verify operation of equipment and devices but do not simulate
operation of the system in fi re conditions.
Full Flow Trip Tests are conducted with the water supply main control valve fully open. The dry valve is operated by opening the system
test valve to simulate the opening of a sprinkler in fi re conditions. When the dry valve operates, the sprinkler piping will be fl ooded with
water.
Performance of a Full Flow Trip Test is recommended during warm weather at least once every three years. More frequent testing may
be required by the Authority Having Jurisdiction.

To disassemble The Dry Valve:
Disconnect the trim and remove the valve from the system piping.
Use the Dry Valve Reset Bar/Wrench, part number 02977BM, to remove hand-hole cover bolts (21) from base (22).
Remove housing (1) from base (22). Member assembly components (5-15), and (17-19, 21, 25) are accessible for replace-
ment.
When inspection and/or replacement of Member assembly components is complete Re-assemble the dry valve.
To re-assemble the dry valve:
Reverse disassembly procedures a through c in step 13 above.
Socket-set screw (23) will need adjustment. After the valve has been completely reassembled, latch the clapper in place.
With a 1/4” (6,35 mm) Allen wrench, turn the screw clockwise until it contacts the hook (24). Then, turn the screw one
complete turn counter-clockwise. Set the system and trip test the valve to verify proper operation of the valve.
To remove Hook Assembly (15):
Remove a retaining ring (7) from one end of hook rod (6b).
Slide rod (6b) out of the bushings in air plate assembly (11) to free hook assembly (15).
Remove hook assembly (15).
To re-install Hook Assembly (15):
Reverse disassembly procedures a through c in step 15 above.
To remove Clapper Arm Assembly (8) and Spring (9):
Remove a retaining ring (7) from one end of clapper arm rod (10).
Slide clapper arm rod (10) out of the bushings in air plate assembly (11) to free clapper arm assembly (8) taking care to
retrieve spring (9).
Remove clapper arm assembly (8), and spring (9).
To re-install Clapper Arm Assembly (8):
Reverse disassembly procedures a through c in step 17 above.
To remove Diaphragm (12) and Diaphragm Retainer (13):
Use a 9/16” wrench to remove hex-head screws (14).
Remove diaphragm retainer (13) and diaphragm (12) for replacement. If the diaphragm rubber shows signs of wear, such
as cracking or cuts, replace the rubber diaphragm.
To re-install Diaphragm (12) and Diaphragm Retainer (13):
Reverse disassembly procedures a and b in step 19 above.
When re-installing diaphragm retainer (13), cross tighten hex-head screws (14) to 20 ft. lbs. of torque for even compres-
sion of diaphragm (12).
When assembling base (22) to housing (1):
Invert housing (1) on work bench so holes for hand-hole cover bolts (21) are facing up.
Position complete member sub-assembly (5-15 & 17-19, 21, 25) with screw holes in diaphragm (12), aligned with
screw holes in inverted housing (1). Use care to align screw holes so hook assembly (15) properly aligns with set
screw (23).
Position base (22) over inverted housing (1) with member assembly (5-15 & 17-19, 21, 25). Align screw holes so ½”
(15 mm) NPT trim connection in base (22) aligns with ½” (15 mm) NPT trim connection in housing (1).
Install hand-hole cover bolts (21) finger tight only.
Cross-tighten all hand-hole cover bolts (21), to 90 ft. lbs. of torque to evenly compress diaphragm (12) and maintain
proper alignment of member sub-assembly (5-15 & 17-19, 21, 25).

Table 3 - Troubleshooting GuideCondition: Possible causes: Suggested action:
The valve trips when no
sprinkler has fused
Loss of air pressure in the
system
Check the system for leaks and check for proper air sup-
ply. A Viking Air Maintenance Device should be installed
on each system equipped with an automatic air supply.
Consider adding a maintenance air compressor.
An extreme pressure surge in
the water supply
Increase the air pressure on the system. The maximum
limit is 60 PSI (4.1 bar). Note: Increasing system pressure
may increase trip time of the dry valve.
Water constantly pass-
ing through the drip
check when the valve is
in the SET position
Water leaking over the wa-
ter seat into the intermediate
chamber
Inspect and clean the water seat and clapper rubber (see
step 5 of paragraph 4, Installation, Placing the Valve in
Service). Consider replacing the clapper rubber. If the wa-
ter seat has been pitted or damaged by debris, it may be
necessary to replace the base assembly.
Alarm test valve in the bypass
connection of the dry valve
trim not tightly closed
Verify that water is not getting past alarm test valve.
Air constantly passing
through the drip check
when the valve is in the
SET position
Air leaking over the air seat
into the intermediate cham-
ber
Inspect and clean the air seat and clapper rubber (see
step 5 of paragraph 4, Installation, Placing the Valve in
Service). Consider replacing the clapper rubber. If the air
seat has been pitted or damaged by debris, it may be
necessary to replace the air plate assembly.
Air leaking past the rubber
diaphragm
Inspect the rubber diaphragm for deterioration. If neces-
sary, replace the diaphragm.
Clapper will not latch
Incorrect resetting tool
Verify that the re-setting tool used is smooth and of the
proper strength and diameter* to provide the required
force at the appropriate angle to cause the latching hook
to slide over the clapper arm when setting the dry valve.*The Viking Re-setting tool is a 3/4” (19 mm) diameter cold rolled steel bar, chamfered at one end and a standard 15/16” hex-socket on other end. (PN 02977BM)
The hook not sliding on the
re-setting tool
File or grind the re-setting tool. Remove any rough spots
to provide a smooth sliding surface and proper clear-
ance.
Clapper rubber worn Replace the clapper rubber.
Internal parts damaged by
accidental application of high
pressure
Replace the valve member assembly.
The valve latches but
will not remain set
Improper resetting procedureSee paragraph 4, Installation, Placing the Valve in Serv-
ice
Inadequate air supplySee paragraph 4, Installation, Placing the Valve in Serv-
ice.
Air pressure and priming wa-
ter passing through the inter-
mediate chamber and out of
the drip check
Clean the air seat and the clapper rubber. Replace the
clapper rubber, if worn.
