• Economizer Assembly Types Hood Assembly Wiring Connection

• 2~10 vdc• 4~20 ma

• Safety Improper installation, modification, service and

maintenance may cause personal and/or property damage.

Contact qualified installer, servicer or distributor for information or assistance

Wear safety glasses and work gloves.Have quenching cloth and fire extinguisher availableRead all Installation Instructions prior to beginning

workFollow all Local and National building and electrical

codes

• Fire ExplosionDisconnect gas piping from unit when leak

testing

DO NOT exceed gas pressures greater than 0.5 psig/3450 Pa to gas valve, damage will occur

If pressure testing BELOW 0.5 psig, isolate gas valve from piping using shut-off valve

• Electrical ShockBefore servicing or maintaining unit, turn off

power supply at disconnect/breaker and install Lock-Out tag

Test for voltage with multi-meter prior to performing service

Some installation may have more than one power source, i.e. dual power wiring and units with heat strips

• RefrigerantPuron® (R-410A) refrigerant systems operate

at higher pressures than R-22 systems

Do not use R-22 components or service equipment on Puron® systems

POE oil can cause damage to roof of building. If spilled use dry absorbent materials to eliminate spill.

• Cut HazardsAlways wear gloves, protective clothing and

safety glasses when handling sheet metal components. Failure to do this can result in cuts or abrasions.

Use caution when placing sheet metal components on rubber membrane roofing. Sharp edges can penetrate roofing.

Pre Planning

• Job Survey Consult Local Bldg Codes, NEC (National Electric Code) and

ANSI/NFPA 70 for installation requirements Determine unit location Check for overhead obstructions (for lifting) and proximity to

walls or parapets

• Plan for Unit Location Proper curb/unit support within structure Provide for Minimum Service and Safety clearances Clearances to combustible materials Allow for adequate Combustion and Ventilation

Pre Planning

• Service ClearanceA: 48” Unit disconnect

36” If “B” < 12”18” No disconnect, C/O18” Service 12” Minimum clearance

B: 42” Grounded surface (metal, masonry wall)

• Lifting/Setting Unit• Use top crate of unit or spreader bars

when lifting.– Carefully lower top crate from roof once unit placed on curb

• Review the maximum weights of the units as listed in the Installation Instructions prior to lifting

* Measured below roof curb 003~014 // 024~150

Return Air w/o Economizer -0.35 in w.c.

Return Air w/ Economizer -0.45 in w.c.

Placement/Setting Unitprior to setting unit

• Cautions:1) Condensate Drain

• If condensate drain will exit unit horizontally proceed to setting unit

• If condensate drain will exit through the pan center drain and through the roof curb, install PVC fitting prior to setting unit.

• If not using center drain outlet, check to ensure outlet plug is installed and tight

2) Through the Pan Connections• Provides capability to draw

power, control wiring and field supplied gas piping

• Install prior to setting unit on curb

3) Through the Curb Connections• Provides capability to run

gas line up “under the curb” then exit “side of curb” to connect to unit

Placement/Setting Unitprior to setting unit

Economizer Assembly

• Types Manual

• Can be used in Vertical/Horizontal configuration

• Adjustable from 0% - 100% Two Position

• Can be used in Vertical/Horizontal configuration

• Adjustable from 25% - 100% Modulating

• Different Vertical/Horizontal• Provides for Minimum and Min

to100% OA capability based on OD conditions

Burner compartment Attach with two screws Clearance to combustibles:

48”

• Flue Deflector (Accessory) CRFLUEDS001A00 2 ~ 12.5 ton units Reduces clearance to

combustibles to 18”

Preparing Unit for Start-Up

• Gas Piping Local/National Codes

US (NFPA54/ANSI Z223.1 NFGC)CAN (CAN/CSA B149.1 & B149.2)

• Standard gas design Up to 2000’ Convertible up to 6000’

• US: Derate 4% per 1000’ above sea level• CAN: Derate 10% between 2000’ – 4500’

• Gas pressure at GV inlet Nat Gas: Min 4”w.c. - Max 13”w.c. LP Gas: Min 11”w.c. - Max 13”w.c. (req’s Accy Kit) Fitting size: ½” for 03~08 (024-090) units; ¾” 012~014

(120~150) units• Size piping for maximum pressure

drop of 0.5”w.c. between unit GV and gas source• Three Gas Line Approaches

Horizontal to GV (across roof) Thru-Curb (Kit required) Thru-Base Pan (Kit required)

• Always use “Back-Up” wrench on Gas Valve neck (wrench fitting) when connecting piping


Through the Curb

Through the Base Pan

• Condensate Drain ¾” Connection: Two locations

• Horizontal– Exiting out the duct connection end of unit– Piping pitch: 1 inch per 10 ft away from unit – Do not use pipe smaller than ¾”– 4 inch trap recommended– Protect from freezing– Check “Center Drain Plug” for tightness

prior to setting unit on curb

• Center– Exiting below unit from center of

condensate pan– Remove “Center Drain Plug”– Piping pitch: 1 inch per 10 ft away from unit – Do not use pipe smaller than ¾”– 4 inch trap recommended– Protect from freezing (if necessary)


• Electrical Connections Non Powered Convenience Outlet (C/0):

• Requires separate 125 vac 15amp circuit Unit Powered: Incorporates step down transformer

• Convenience Outlet– Connect transformer primary per diagram– Powered (always energized): Connect C/O wires to “Line”

side of disconnect or incoming power, or local codes– De-energized (powered with disconnect): Connect C/O wires

to “Load” side of disconnect, or local codes

• Power: All units except 208/230 vac factory wired for voltage

shown on unit name plate.• 208 vac requires Low Voltage transformer wiring.

Connect black from 230 vac tap on transformer to 208 vac transformer tap.

Units without FIOP Disconnect• Field power wires connect to Compressor Contactor “C”

terminals 11 – 13 and Indoor Fan Contactor Units with FIOP Disconnect

• Remove factory test leads on Line side of Disconnect, discard

• Additional info later


• Field Control WiringThermostat:
