theunit, insertthescrewsthroughtheductflanges only . DONOT insertthescrews throughthecasing. Outdoor duct work must be insulated and waterproofed.
-
NOTE: Be sure to note supply and return openings.
WARNING:Donotpermitoverhanging structures or shrubs to
obstruct the condenser air discharge outlet.
DUCT WORK
These units are adaptable to downflow use as well as rear supply and return air duct openings. To convert to downflow, use the following steps:
1. Remove the duct covers found in the bottom return and supply air duct openings. There are four (4) screws secur ing each duct cover (save these screws to use later).
2. Installtheduct covers,removedin stepone,to therearsup ply and return air duct openings. Secure with the four (4) screws used in step one.
3. Seal duct covers with silicone caulk.
Downflow units must have an “L”-shaped supply duct without any outlets or registers located below the outlet of the unit.
Duct work should be designed and sized according to the methods of the Air Conditioning Contractors of America (ACCA), as set forth in their Manual D.
A closed return duct system shall be used. This shall not pre­clude use of economizers or ventilation air intake. Flexible joints may be used in the supply and return duct work to mini­mize the transmission of noise.
Refer to Figure 3 for information concerning rear and bottom supply and return air duct openings.
FILTERS
Singlephase unitsareshipped withouta filterandistheresponsi bilityof theinstaller tosecure afilter inthe returnair ductworkor install a Filter/Frame Kit (1FF0114).
A filter rack and high velocity filters are standard on three phase units.
-
Filters must always be used and must be kept clean. When filters become dirt laden, insufficient air will be delivered by
-
the blower, decreasing your units efficiency and increasing operating costs and wear-and-tear on the unit and controls.
Filters should be checked monthly especially since this unit is used for both heating and cooling.
CONDENSATE DRAIN
A condensate trap is required to be installed in the conden­sate drain. The plumbing must conform to local codes. Use a sealing compound on male pipe threads. Install the conden­sate drain line (
3
“ NPTF) to spill into an open drain.

Checking Supply Air CFM
To check the supply air CFM after the initial balancing has been completed:
1.Remove the two ¼ inch dot plugs in the duct panel.

curate. To ensure a dry coil, the compressors should be de activated while the test is being run.
4.Knowing the pressure drop across a dry coil, the actual CFM through the unit can be determined from the curve in Coil Delta P vs. Supply Air CFM figure.
-
2.Insert at least 8 inches of ¼ inch tubing into each of these holes for sufficient penetration into the airflow on both sides of the indoor coil.
3.Using an inclined manometer, determine the pressure drop across the dry evaporator coil. Since the moisture on an evaporator coil may vary greatly, measuring the pressure drop across a wet coil under field conditions would be inac

SEQUENCE OF OPERATION
Anti-short Cycle Timer
Thisunit hasan anti-shortcycle timerbuilt into thedefrost con trol.This timer willnot permitthe compressorto startwithin five minutesafter thecompletion ofthe lastcycle orpower interrup tion. To bypass the anti-short cycle feature, short the “TEST” pins together for 2 seconds.
The following sequences of operation are based on using a standard single-stage heat pump thermostat.
Cooling Operation
WITH POWER TO UNIT AND THERMOSTAT IN COOLING MODE.
1. If the fan switch on the thermostat is in the “ON” position, the 24 volts at “G” will energize the “K1" relay on the fan control board, close the ”K1" relay contacts, and energize the indoorblower motor.If the fanswitch on the thermostat isinthe “AUTO”position, theblower willoperate only when there is a call for cooling by the thermostat.
2. Ona call forcooling, thethermostat willsend 24 voltsto “Y” and “O” on the fan control board. After the anti-short cycle period is complete,The 24 volt signal will energize contac tor “M1", and the reversing valve solenoid. Power will be supplied tothe compressor andoutdoor fan motor,and the reversing valve willswitch to the cooling position. Ifthe fan switch onthe thermostat is onthe ”AUTO" position,the fan control will energize the indoor blower.
3. When the demand for cooling has been satisfied, the 24 volt“Y” signalis removedand the“M1" contactorwill bede­energized. Ifthe fan switchon thethermostatis inthe ”ON" position, the indoor blower will continue to run. If the fan switchisinthe“AUTO”position, the“K1"relaywill openand de-energize the indoorblower motor after a 60 second de­lay,

statisin the“ON”position, theindoorblowerwill continueto run.Ifthe fanswitchis inthe“AUTO”position, the“K1"relay willopen andde-energize theindoor blowermotor afterthe appropriate time delay.
Please refer to Tables 7 and 8 for more information.
Defrost Operation
The minimum time between defrosts can be field selected at 30, 60 or 90 minutes. The default time is 90 minutes if the jumper is not installed.
Defrostwill initiatewhen thedefrost sensor,locatedon theout doorcoil, sensesatemperature below31°F andwhen thetime since the last defrost is greater than the selected time on the defrost control. The defrost cycle terminates when either the defrost sensor reaches 55°F or the unit has been in defrost mode for 10 minutes. If the room thermostatopens during de frost,the unitwillresume operationindefrost whenthe thermo stat re-closes.
During the defrost mode, the defrost control will provide a 24
-
volt signal from terminal “W1/66" to the fan control terminal ”W1".This signalwillenergize electricheatstage1,if theunitis so equipped.
For troubleshooting purposes, thedefrost cycle canbe manu ally initiated by shorting the “TEST” pins together for 5 sec onds.Defrostwill terminatenormallyduring the“TEST”mode.
Heat Pump Safety Switch Operation
If the unit is equipped with the field installed upgrade safety package, the refrigeration system will be protected against high or low refrigerant pressure and low indoor coil tempera­ture.If anyof thesethreesafety switchesopens, theunit willbe shutoff forthe 5minute anti-shortcycle time.Oncethishasex­pired, asix hour elapsedrun timer begins.If a secondopening of a safety switch occurs during this six hour period, the com­pressor will be locked out.

2. Ona callfor heating,the thermostatwill send24 voltsto “Y” on thefan control board. Afterthe anti-short cycle periodis complete, the 24 volts signal will energize contactor coil “M1"and powerwill besupplied tothe compressorand out door fanmotor. Thereversing valve willremain in theheat ing position. If the fan switch on the thermostat is in the ”AUTO" position, the fan control will energize the indoor blower.
3. For units equipped with supplementary electric heat, if the heat pump cannot meet the demand, the thermostat “W” willsend24 voltsto “W2"on thefancontrol board.This sig nal will also be sent through the defrost control terminals ”W" and “W1/66" andbackto the fan control ”W1". This 24 volt signal will energize all stages of electric heat.
4. When theheating demand issatisfied, the electricheatwill bede-energized when the 24 volt “W”signal is removed, and the “M1" contactor will be de-energized when the 24 volt ”Y" signal is removed. If the fan switch on the thermo
Resetting the lockout function is accomplished by;
1. Removing power from the control's thermostat 1st stage (Y)inputfor atimenot toexceed5seconds (ON-OFF-ON).
2. Removing power from “R” for more than 2 seconds.
3. Shortingthe“TEST” pinstogetherfor morethan2seconds.

disabled. Only a power cycle will clear the state. During the soft lockout period, the fan responds to thermostat
input but the heaters are enabled. This is to sense a failed heater relay. The limit cyclecount is reset at the startof a heat request. If the limit remains open for period of 80 seconds or more, the control is immediately put intoahard lockout condi tion. Only a power cycle will clear this state.
-
SECURE OWNER'S APPROVAL: When the system is functioning properly, secure the owner's approval. Show him
the location of all disconnect switches and the thermostat. Teach him how to start and stop the unit and how to adjust tem perature settings within the limitations of the system.
