IMPORTANT:Read this owner information to become familiar with the capabilities and use of yourappliance. Keep this with literature on other appliances where you have easy access to itin the future. If a problem occurs, check the instructions and follow recommendations given.If these suggestions don't eliminate your problem, call your installing contractor ordistributor in your area.

INTRODUCTION

Your heat pump is a unique, all weather comfort-control system appliance. The basic operationof the heating/cooling system is described andillustrated on page 1 of this manual. Thesurprising fact that heat exists in air even atbelow-freezing temperatures is actually the basiclaw of physics which the heat pump uses toprovide energy saving heating comfort. Atoutdoor temperatures of 47 ° Fahrenheit or (or

8° Celsius), your heat pump can deliverapproximately 2 to 3 units of heat energy pereach unit of electrical energy used, as com paredto a maximum of only 1 unit of heat energyproduced with conventional heating systems.During the cooling season, the heat pumpreverses the flow of the heat-absorbingrefrigerant to become an energy-efficient, centralair conditioner.

SECTION 1. OWNER INFORMATION

Your heat pump will heat and cool your homeyear round, saving your energy dollars. Duringthe summer, a heat pump performs like anynormal air conditioner. That is, the excess heatenergy inside the home is absorbed by therefrigerant and exhausted outside the home.During the winter months, a heat pump performslike an air conditioner run in reverse. That is,available heat energy outside the home isabsorbed by the refrigerant and exhausted insidethe home. This is an efficient heating meansbecause you only pay for "moving" the heat fromthe outdoors to the indoor area. You do not payto generate the heat, as is the case with moretraditional furnace designs.

It is the sole responsibility of the homeowner tomake certain that the heat pump has beencorrectly set upand adjusted to operate properly.

The manufacturer warrants the heat pump to befree from defects in workmanship or material fora period of one year. A warranty certificate withfull details is included with the heat pump.However, we will not be responsible for anycosts found necessary to correct problems dueto improper setup, improper installation,adjustments, improper operating procedure onthe part of the user, etc.

Some specific examples of service calls whichare not included in the limited warranty are:

1. Correcting wiring problems in the electricalcircuit supplying the heat pump.

2. Resetting circuit breakers or other switches.

3. Adjusting or calibrating of thermostat.

To avoid misunderstandings at a later date,carefully review these responsibilities with yourdealer or service company.

OPERATING INSTRUCTIONS

To Operate Your Heat Pump For Cooling --

1. Set the thermostat system switch to COOLand the thermostat fan switch to AUTO. (SeeFigure 1)

2. Set the thermostat temperature selector to thedesired cooling temperature. The outdoor unitfan, the indoor blower, and the compressorwill all cycle on and off to maintain the indoortemperature at the desired cooling level.

NOTE: If the thermostat temperature level is re-adjusted, or if the thermostat system switch isre-positioned, the outdoor unit fan and thecompressor may not start immediately. Aprotective timer circuit holds the compressorand the outdoor fan off for approximately fiveminutes following a previous operation or theinterruption of the main electric power.

heating)will be used as a sourceof heat.Sustaineduseof electricresistanceheat inplaceoftheheatpumpwillresultinanincreaseinelectricutilitycosts.

Defrost -- During cold weather heatingoperation, the outdoor unit will develop a coatingof snow and ice on the heat transfer coil. This is

normal and the unit will periodically defrost itself.During the defrost cycle, the outdoor fan willstop, while the compressor continues to run andheat the outdoor coil, causing the snow and iceto melt. During defrost, there may be somesteam rise from the outdoor unit as the warm coilcauses some melted frost to evaporate.

2. UNPACK THE UNIT

It is recommended that the unit be unpacked atthe installation site to minimize damage due tohandling.

CAUTION:Do not tip the unit on its side. Oil mayenter the compressor cylinders andcause starting trouble. If unit has

been set on its side, restore to uprightposition and do not run for severalhours. Then run unit for a fewseconds.Do this three or four times with five

minutes between runs.

The supply and return fittings are included withselect models. If supplied, the duct fittings areshipped in the supply duct. They attach to theunit openings with a flange and beadarrangement, secured with two sheet metalscrews. Note: For ease of access, install fittingbefore positioning unit in final location.

SUPPLY DUCTPosition the supply duct collar, if supplied, so theedge of the unit opening fits between the flangeand the bead. Overlap the collar ends keepingthe small screw holes underneath. Align theholes in the crimped area and install one screw.

Note: It may be necessary to loosen the fourscrews that hold the transition duct in order toinstall the supply fitting. Re-tighten wheninstallation is complete.

Tap collar as necessary to ensure engagementwith unit opening and install second screw.Tighten first screw. Rotate collar clockwise sojoint is near three o'clock position.

located inside a closet with Iouvered doors thathave an open area equal to or greater than the12" x 20" grille furnished. The return air grille canbe placed in the wall of a closet and the air ductedinto the filter box through a boxed-in area at thecloset floor level. Make sure the filter is readilyaccessible.

When locating the supply damper(s), carefullycheck floor joists and frame members thatcould interfere with the installation of the damperor flexible duct. Ideally, the damper should belocated in the bottom of the main duct, forwardof center of the home, at least three feet fromthe nearest register. The round supply openingin the slanted side of the damper should facethe side of the home where the heat pump islocated. To locate the center of the heat duct,first cut a small hole in the fiberboard below theduct at the desired location. After locating theduct center, cut a hole approximately 3/4" largerthan the damper opening in the fiberboard. Cuta 9-1/8" x 13-1/8" hole in the duct and bend overall tabs flat on the inside of the heat duct. Afterinserting the damper into the duct, bend over alltabs fiat on the inside of the heat duct. Seal theopening between the fiberboard and damper orflexible duct.

DUCTING SYSTEM

After determining the location of the return airopening, start the installation from under thehome by cutting asmall hole in the fiber underboardto determine how the floor joist location will affectcutting the opening needed for the box. Floorjoists generally are located on 16" centers, leaving14-3/8" between joists. After measuring thereturn air box (approximately 12-1/4" x 20-1/4"),cut the hole through the floor so that the box willfit between the floor joists. Care should be takenwhen cutting through carpeting to avoid snags. Inmost installations it will be necessary to cut asimilar hole in the fiberboard directly under thehole in the floor. However, if the floor is more thanten inches deep, it will only be necessary to cut ahole for the collar on the return air box or for theinsulated duct.

Set the box into the opening and fasten withscrews or nails. Put the filter and return air grillein place.

5. LOCATING AND INSTALLING THE

SUPPLY DAMPER(S)

DUCT REQUIREMENTSThe supply duct system, including the numberand type of registers, will have much moreeffect on the performance the system thanany other factor. The duct must be sufficientlylarge to conduct an adequate amount of air toeach register.

THE HEAT PUMP SYSTEM WILL NOT COOLOR HEAT THE HOME IF THE AIR IS LOSTTO THE OUTSIDE THROUGH LEAKS INTHE DUCT SYSTEM. ALSO, DUCTS WHICHARE COLLAPSED OR RESTRICTED BYFOREIGN OBJECTS WILL PREVENTADEQUATE AIR FLOW.

Note: For highly resistiveduct systems it may benecessary to add an additional return air duct toachieve maximum performance.

CONNECTING THE RETURN AND SUPPLYAIR FLEXIBLE DUCTS

The return duct may be 12" or 14" diameterdepending on unit size. (See Table on page 4)

a. The supply duct for all units is twelve inchesin diameter.

b. The flexible ducts can be connected to thecorresponding fittings with the clampsprovided with the ducts. Note: All connectionsshould be leak tight or a loss in coolingcapacity will result.

Figure 5. Supply Damper6

c. The flexible ducts may be cut to the requiredlength, see instructions packed with duct.Keep all ducts as short and straight aspossible. Avoid sharp bends.

d. Ducts may be spliced with sheet metalsleeves and clamps. (See Ducting InstallationAccessories below.)

e. Once the inner duct is connected to the

proper fitting, the insulation and plasticsleeveshould be pulled over the connection andclamped.

f. For homes with multiple supply ducts or forspecial applications, a Y fitting is available todivide the supply air so it can be ducted todifferent areas of the home for more efficientcooling. Note: The Y fitting should beinsulated for maximum performance.

Blower Speed -- The blower speed is preset atthe factory for operation at the same speed forheating and cooling. For optimum system

pump is the smallest size that will permit theequipment to run under normal use and servicewithout nuisance trips. Such a device, sizedproperly, gives maximum equipment protection.The principal reason for specifying a time delaytype is to prevent nuisance trips when the unitstarts.

In the event that a fuse does blow or a breaker

trips, always determine the reason. Do notarbitrarily put in a larger fuse or breaker and donot, in any case, exceed the maximum size listedon the data label of the unit.

3. LOCATING THE THERMOSTAT

Locate the thermostat away from drafts andslamming doors and place it where there is a freeflowof air. Mount on an inside wall approximatelyfive feet from the floor.

Do not locate near a lamp, kitchen range, directsunlight, or in line with air flow from supplyregisters.

Connect the Heat.Cool Thermostat: The heat-

cool thermostat is equipped witha system HEAT-COOL switch, which provides a positive means ofpreventing simultaneous operation of the heatingand cooling units. Thethermostatisalso equippedwith an ON-AUTO fan switch which allows thehome owner to operate the indoor blower whenair circulation is desired.

Connect the low voltage wires to the respectiveterminals on the thermostat base. See thermo-stat instruction sheet for more detailed informa-tion. (See Figure 10).

If two stage heating is desired, an optionaloutdoor thermostat may be installed:Connect the thermostat to the orange tow volt-age wire and the W terminal on the indoorthermostat base (See Figure 10). See the ther-

mostat instructions for details on setting theoutdoor thermostat.

4. DEFROST CYCLE CONTROL

The defrost cycle is initiated via a signal from thedefrost sensor on the outdoor coil to the defrost

control board inside the control panel indicatingthe coil temperature is low enough to startaccumulating frost. The board has intervalsettings of 30 minutes, 60 minutes, and 90minutes.These time intervals represent the timeelapsed before defrosting cycle starts and theyare dependent on the climate conditions of theinstallation. A 30 minute setting would berecommended ina moist climate such as Seattle,Washington. A 90 minute setting would beadequate in a dry climate such as southernArizona. The factory time interval setting is 30minutes.

5. OUTDOOR THERMOSTAT (if supplied)

The outdoor thermostat prevents the electricalauxiliary heat (if used) from operating above adesired set point. Selection of the set point isdetermined from the building design heat load.

The thermostat is adjustable from 45°F to 0°F.• The factory temperature setting is at 40°F.

6. ELECTRIC HEAT PACKAGE (OPTIONAL)

The heat pumps are shipped withoutan auxiliaryelectric heat kit installed. If electric heat isdesired, an accessory Heater Kit must be fieldinstalled. See Specifications Sheet for availablekits and their application.

Select the correct size heat package for theinstallation.

Follow installation instructions provided witheach heater kit.

Installation is most easily accomplishedbefore making duct or electrical connections.

Blower speed must be set to high speed forelectric heat operation.
