COOLING SEASON—Thermostat set at “Cool” and “FanAuto,” outside air damper goes to “minimum fresh air” positionwhen cooling thermostat closes, energizing mechanical cool-ing. When cooling thermostat is satisfied, mechanical coolingis de-energized, and outside air damper closes.INTERMEDIATE SEASON—Same as for cooling season,except that cooling thermostat closes, starting indoor blowermotor, the enthalpy control, mounted on outside air, deter-mines if “free” cooling or mechanical cooling should be utilized.If outside air conditions are suitable for cooling, the mechani-cal cooling remains off and the mixed air controller modulatesthe damper motor to assume the proper damper position tomaintain mixed air setting. If outside conditions are not suit-able for cooling, then the dampers go to “minimum fresh air”position and mechanical cooling is energized.

HEATING SEASON—Damper always stays at “minimum freshair” position while fan motor is operating. Outside air dampercloses when blower motor is off. “Minimum fresh air” positionmust not allow mixed air temperatures to air handler below50°F. during heating seasons.CAUTION: Because of the possibility of freeze damage, it isnot recommended that hot water or steam coils be used withthe mixing box accessory, unless provision is made to shut-offthe outside air duct 100% during freezing conditions.Another possible system enhancement would be to install anair proving switch in the air handler supply duct wired in serieswith the compressor contactor coil (24V) which would lock outthe compressor in the event of air flow failure.

REFRIGERANT PIPINGThe following will be of help in accomplishing a successfulinstallation.1. Size liquid line for no more than 50 PSIG pressure drop.2. Size suction lines for no more than 2° F loss whichcorresponds to approximately 5 PSIG pressure drop.

3. When evaporator is installed below condensing unit, donot exceed the recommended suction line O.D. This willinsure adequate velocities for proper oil return.

4. Install (optional field installed) sight glass in liquid line.5. Pitch all horizontal suction lines downward in the direc-tion of flow.

6. When making up refrigerant piping, take every precau-tion to prevent dirt and moisture from entering the piping.

7. Locate the condensing unit and evaporator(s) as closetogether as possible to minimize piping runs.

NOTE: Refer to suction and liquid line pressure drop chartsfound in condensing unit literature.

INSPECTIONThe complete unit should be examined thoroughly uponreceipt, for either hidden or apparent damage, and if neces-sary, a claim should be entered at once against the last carrier.It is the responsibility of the consignee to file such a claimsince the unit is shipped F.O.B. Factory.

LOCATIONThe location of the unit must be determined with the followingfactors in mind: available electric power, plumbing facilities andample space for arranging the refrigeration equipment, andconforming with proper duct design. In addition, provisionshould also be made for accessibility to service parts and forcomplete removal and replacement of any replaceable part.

INSTALLATIONThe construction of the building must be substantial enough tosupport the unit. Set the air handler on a suitable foundation sothat the weight is evenly distributed. After locating the unit,shim up the side opposite the drain to allow the water to drainfrom the pan.If return air duct is not used, applicable installation codes maylimit this cabinet to single story buildings only.See example of both vertical and horizontal mounting.The units may also be suspended from the ceiling.Supply conduit to equipment must terminate at junction boxlocated in the unit.NOTE: When installed in horizontal position, drain end must be1/2” lower than leaving air end.PRODUCT SUITABLE FOR INDOOR USE ONLY.

CONDENSATE DRAIN PIPING• Two drain couplings are provided on all models. Selecteither one for condensate outlet and plug the other.

• Consult local codes or ordinances for specific require-ments regarding condensate drain.

• Condensate drain is open to atmosphere and must betrapped. Trap must be at least 3 inches deep and madeof flexible material or fabricated to prevent freeze-up.

• If air handler is installed in a non-conditioned space, it isrecommended an auxiliary drain pan be fabricated andinstalled under entire unit.

• Pitch the drain line at least 1/4 inch per foot away fromthe drain pan.

• Do not reduce the drain line size from the connectionsize provided on the unit.

• Do not connect the drain line to a closed sewer line.

MOTOR MOUNTINGOne of the most critical aspects of an air handler installationis the mounting of the motor, motor sheave, fan pulley andthe belts, and the adjustment of these items.The motor base for the air handlers is raised or lowered bymeans of the adjusting hex nuts.

MOTOR SHEAVE AND FAN PULLEYMOUNTING AND ADJUSTMENTThe adjustable pitch sheave which is mounted on the motorshaft controls the fan speed. To adjust the fan speed referto figure at right, proceed as follows:a. Loosen the set screw, item 1.b. Rotate the adjustable sheave, item 2, to the desiredposition.

c. Lock the adjustable sheave in place by tightening the setscrew, item 1.

NOTE: The adjustable sheave is not to be used to adjustbelt tension.

WARNINGBEFORE MAKING FAN ADJUSTMENTS, BE SURE THEMAIN ELECTRICAL DISCONNECT SWITCH IS IN THE“OFF” POSITION TO PREVENT POSSIBLE INJURY DUETO ACCIDENTAL OPERATION OF THE MOTOR.

FAN BELT ALIGNMENT AND ADJUSTMENTPlace belt on the groove of the fan pulley and motor sheaveto obtain the approximate alignment and belt tension.Remove the belt and align the fan pulley and motor sheaveusing a straight edge. When the pulley and sheave areproperly aligned, re-install belt. Do not force or pry the beltonto the pulley and sheave. With the belt in place, adjust so

that all the slack is on one side of the drive. The belt shouldhave from 3/4” to 1” of slack at 3 lbs. pressure. Adjust thebelt to this tension, by raising or lowering the swing basevia the adjusting rods and nuts.

PRE-START CHECK LIST 1. Leak test entire system. 2. Check motor mounting to make sure all nuts are tight. 3. Check motor sheave and fan pulley to make sure they

are in proper alignment and set screws are tight. 4. Check belt tension—belts should be fairly tight for the

initial “start-up”. 5. Check bearing—collar set screws on fan shaft to make

sure they are tight. 6. Ball type bearings are factory lubricated and do not

require additional grease before starting. 7. Rotate blower shaft by hand to be sure it is free. 8. Check motor and fan rotation. 9. Check all screws, bolts, set screws and piping connec-

tions for tightness.10. Check drain.11. Insure that filters are in place.

12. Insure all manual valves are open.13. Be sure that electrical controls and motors are properly

wired and fused in accordance with applicable codes.14. Check wheel position in scrolls. See Figure 1 a and b.

OPERATING INSTRUCTIONS1. Start fan motor—immediately observe noise level andsecure fan motor if unusual sound is heard. Check bear-ings in particular for proper noise level and temperature.Be sure fans do not rub on scrolls.

2. Check fan RPM and adjust as necessary.3. Check for motor overloading.4. Check for proper CFM delivery.

5. Check all necessary items and controls for proper opera-tion.

6. Insure that condensate is being properly dischargedfrom drain pan.

LUBRICATIONGREASING BALL BEARINGS—MOTORSAll ball bearing motors are prelubricated and do not requirethe addition of grease at time of installation. However, peri-odic cleaning out and renewal of grease in ball bearings isnecessary. Please note that extreme care must be exer-cised to prevent foreign matter from entering the bearing.

PERIODIC SERVICE AND MAINTENANCE1. Filters—Dirty filters reduce air flow and, in turn, thecapacity of the unit. Therefore, when dirty, replace orclean, depending on the type.

2. Coils—Dirt should not be permitted to build up on thefins of the coils. An air stream or water jet can be usedto remove dirt and lint.

3. Check all moving parts for wear and alignment every six(6) months.

4. Check bearing-collar set screws on fan shaft to makesure they are still tight. Do this at least every six months.THIS IS VERY IMPORTANT.

BEFORE PERFORMING PERIODIC SERVICE ANDMAINTENANCE, BE SURE THE MAIN ELECTRICALDISCONNECT SWITCH IS IN THE “OFF” POSITION TOPREVENT POSSIBLE INJURY DUE TO ACCIDENTALOPERATION OF THE MOTOR.
