Please take a few minutes to read these instructionsbefore you installand/or use your heat pump.

This will help you obtain the full value from your unit. It will also help you avoid any needless

service costs that may result from installing, or operating the unit incorrectly.

PRECAUTIONS FOR INSTALLATION AND SAFE OPERATION

1. Read these instructions carefully. Failure to 4. Refer to page 8 for maintenance proce-

followthese instructions could cause amal- dures.

function of the heat pump unit resulting in

injury, death and/or property damage. 5.

Check your local codes and utility stan-

dan:Is. The installation must comply with

these codes.

Shut off electrical power before making con-

nections on the unit or removing panels for

servicing. (There may be more than one

disconnect.)

Do not operate this unitat outdoortempera-

tures below 60 degrees F on cooling nor

above 75 degrees on heating.

The components of the cabinet may have

sharp edges or protrusions which can cut

you. The tubing and compressor contain

high pressure refrigerant. They must not be

exposed to high temperature or be punc-

tured, as serious injury may result.

The importance of a proper installation cannot be overemphasized. The best designed unit may

operate poorly if installed improperly. Unlike portable appliances where the quality of operation can

usually be determined as it leaves the factory, the performance of an heat pump depends, to a large

extent, on its installation.

Problems are likely to occur if the installer does not follow the procedures outlined.

Wire Size -Inadequate wire sizes can cause an excessive voltage drop(and highcurrent)

resulting in damage to the compressor and fan motors.

Duct Sizes -Inadequate duct size, elbows, distributorsor registers can restrict air flow.

Duct OI)_ings .... , Improperly sealed duct sections can cause considerable loss in cooling

•_ ... capacity due to air leakages, resulting in high operating costs.-

._B_Cbarga: =.Improper charge or introductionof air, moisture or foreign matter can

sedously affect the system performance and reliabilityand is the primary

cause of premature compressor failure.

Heat pumps have proven their reliability over several decades. Years of research, engineering

and only the highest quality component parts and workmanship have gone into the Goettl units to

makethem the most reliable in the industry. Before a model is released for production, it under-

goes comprehensive testing in environmental test rooms with temperatures ranging from sub-

freezing 0° F to 120° F desert temperatures.

LOCAL CODES AND REQUIREMENTS GOVERNING INSTALLATION AND WIRING MU_;T BF

Take special note of grounding requirements for your locale.

LOCATION OF OUTDOOR UNIT

The outdoor section should be in a location which will:

1. Not restrict the air flowto or from the outdoor coil.

2. Minimize the collection of dirt, leaves, and debris.

3. Be shaded if at all possible.

4. Provide the shortest distance for refrigerant piping.

5. Offer convenient electrical service.

6. Be no closer than 18 inches from a solid wall.

7. Have a solid base, such as a concrete slab, not connected to the buildingfoundation.

....See table 3 for recommended refrigerant line sizes and refrigerant charges based on the following

'specifications:

1. R-22 at 50 degree evaporating and 100 degree liquidtemperatures.

2. Liquid lines not to exceed 3 PSI pressure drop.

3. Suction lines not to exceed 3 PSI pressure drop at 1500 ft./min, minimum velocity.

.For vertical rises, the suction line sizes as recommended for the _ run are to be

used. (Oil traps will not be required if this is adhered to. For risers over 20 ft., consultfactory

for guidance).

5. Any oil used must be approved by the applicable compressor manufacturer wSuniso 3G-S or

Texaco WF-32 (Capella B)or Sontcx200LT (Scrolls)

Note: Line sizes 40 ft. and greater may require a hard start kit.

The actual amount of total refrigerant charge for each installation may have to be adjusted to

ensure that unit performance characteristics (compressor electrical current draw and suction

and discharge pressures) are consistentwith those given in the applications tables for the

applicable ambient conditions. (Refer to product catalog for compressor data).

PREUMINARY START UP

1. If power to the unit has been disconnected for more than 24 hours, restore power twelve (12) hours

priorto start up procedure.

COOUNG CYCLE CHECK OUT

With the thermostat calling for cooling and set 10 degrees below room temperature, engage disconnect

switch(es) to start system.

Check the voltage at the compressor motor connections. If the voltage is 10% above or below the

rated voltage or there is a difference greater than 3% between phases, shut down the system and call

the power company. A failure to do so may cause damage to the equipment.

After the unit is in operation, it will take about 30 minutes runningtime to stabilize the system.

In order to check for a properly working system, it is recommended that a thermometer be placed beth

in the retum air and in the air supply. After all insulating of ductworkand adjustments of air registers are

complete, a temperature difference of 15 to 20 degrees is satisfactory.

When the above steps are completed, a check of voltage and amperage draw should be made of all

motors. The readings should be within 10% of the performance ratings given for the specific ambients.

Refer to the performance tables Included with the catalog.

Suction and discharge pressures should also be checked to ensure that they are consistent with the

pressures shown in the catalog for the prevailing ambient cohditions. Also, a suction superheat tem-

perature of 15 degrees F plus or minus 5 degrees F is common for these units when the outdoor ambi-

ent is approximately.95 degrees F. This could be used as a gauge in verifying that the system is not

overcharged or that it has not lost some of its charge.

Finally,the thermostat shouldbe checked out to assureproperoperation. Uteraturepeckedwith the

thermostat will provideInformationfor this check.

After the unit is in operation, it will take about 30 minutes running time to stabilize the system.

In ordertocheck for a properlyworkingsystem, it is recommendedthat athermometer be placedboth

inthe retumair andin the air supply.Afterallinsulatingofductworkand adjustmentsof air registersare

complete, a temperaturedifferenceof 22 to28 degreesis consideredsatisfactory.

When the above steps are completed, acheck of voltage and amperage draw should be made of all

motors. The rea_lings should be within 10% of the performance ratings given for the specifle ambients.

Refer to the performance tables Included with the catalog.

Suction and discharge pressures should also be checked to ensure that they agree reasonably well

with the pressures shown in the catalog for the prevailing ambient conditions. ALso,a suction superheat

temperature of 5 degrees F is common for these units when the outdoor ambient is approximately 47

degrees F. This should be used as a gauge in determining that the system has not lost its charge.

Rnally, the thermostat should be checked out to assure proper operation. Uterature pecked with the

thermostat and subbase will provide Information for this check out. ___

COOUNG CYCLE

With the disconnect in the "ON" position, voltage is supplied to the pdmary of the control transformer and

crankcase heater (where applicable). The control transformer reduces the voltage from either 230 or 208 to

24 volts for the low voltage and the thermostat circuits. With asingle stage cool/single stage heat thermostat

set inthe cooling position, current issupplied from one side of the 24 volt secondary ofthe control transformer

to the "R" terminal of the thermostat. The other side of this transformer connects to the main contactor coil

through the high pressure control. When the thermostat calls for "COOUNG," current from the "R"terminal

is switched on to the "Y" terminal causing the compressor contactor to be energized. The main contactor

closes the contacts inthe highvoltage circuit.The completion ofthis circuitwill start boththe outdoor fan motor

and the compressor simultaneously.

The indoor fan relay which is internally wired from "G" to "Y" in the thermostat subbase is also energized

and starts the indoor fan motor. The system will operate normally and begin to cool.

HEATING CYCLE

With the thermostat set in the heating mode,the =B"terminal energizes the reversing valve relay. With a call

for heat the compressor contactor is energized =W" to "Y" through the jumper wire in the control panel. The

indoor and outdoor fan motors are started in the same manner as in the coolingcycle. The reversing valve

is always energized whenever the system switch on the thermostat is in the heat position. This eliminates the

=swish" at the end of the heating cycle. Only in the de-lce_cycle will the =swish"occur.

Resistance heaters areavailable as an optional fieldinstalled accessory. Heaters are recommended for areas

where winters are severe, because as the outdoor temperature falls, the amount of heat available in the air

decreases, making it more difficultto capture. This fact of nature causes the heat pump capacity to fall at a

time when the heating requirement dses. Resistance heaters can compensate for this difference in capacity.

Heat pumps with resistance heaters require a single stage cool/two stage heat thermostat, with the two stage

thermostat, the resistance heaters are energized if the thermostat istumed more than two degrees higherthan

the indoor temperature, or the indoor temperature falls more than two degrees below the thermostat setting.

The heaters will also be energized during the defrost cycle.

SCROLL COMPRESSOR:

Units equipped with scroll compressors do not have crankcase heaters and do not require hard start kits.

However, they do have a 3 minute anti-short cycle timer and an accumulator (where necessary) for added

compressor .protection.

Never use the scroll compressor to pump Itself down (create a vacuum) by closing off the suction line. The

high vacuum caused by the unit pumplng down could cause severe intemal fusite arcing resulting in a

compressor failure.

Damage resulting from.internal fusite arcing due toextremely low pressure is apparent when an "in-warranty"

compressor is disassembled and will result in denial of warranty claims by the compressor manufacturer.

ANTI-SHORT CYCLE TIMER:

The anti-short cycle timer is to be used for compressor protection.They are described as follows:

FUNCTION -No delay on iniUal start up; but a momentary power failure will initiate a 3 minute delay

before the compressor contactor can be re-energized.

ELECTRONIC DEFROST CONTROL:

This solid state defrost control operates in conjunctionwith an extemal sensor located at a'cold" spot on the

outdoor coil.The control operates on a=Time/Temp" to initiate and "l'emp" to terminate the cycle. The control

will initiate a defrost cycle every 60 minutes (set by the factory) if the coil temperature at the sensor is

approximately 28 degrees F or less. As the coil is being defrosted, its temperature will rise until it reaches

approximately 65 degrees F. At this point the sensor will terminate the defrost cycle. The entire process will

take between one to three minutes. In areas where the air is generally moisture laden and frost is prevalent,

the defrost interval time may be set at 30 minutes by simply moving the jumper wire (see figure 3) from the

T2 pin toT1.

1Be sure the filter is dean. Inspect every 30 days

for operation; if obstructed, clean or replace

filter at once. DO NOT RUN WITHOUT A

FILTER.

Always let the thermostat control the operation

of the system. Never try to "second guess" the

thermostat, or tamper with it. Just set the ther-

mostat atthe comfort level desired AND LEAVE

IT ALONE. If it gets too chilly, just tum the

thermostat up a degree at a time until the

desired level3s'_chleved. Don't tum the ther-

mostat back and forth, as this will cause the

equipment to cycle off.

Heat pumps cannot warm up a house as fast as

a fumace heats it.They pullthe temperature up

slowly; therefore, do not tum the unit on and

immediately expect a warm environment. It

may take as long as a day orso topullup acold,

especially after it has been "soaked" in 30-40

degree ambient for days.

4. Keep both the evaporator and condenser coil

surfaces dean. Accumulation of dirtwill restdct

the airflow and reduce the performance of your

unit (and increase your utilitycosts).

5. Keep condensate drain line clear and clean. All

blower fan motors are factory lubricated and

require no additional lubdcation. The COM-

PRESSOR is hermetically seal_d,.and HAS

NO SERVICEABLE COMPONENTS.

6. Your new heat pump is mounted outdoors. It is

good practice to treat It just as you would your

automobile if it was exposed to the elements

constantly; an occasional coat of wax will give

added protection against the elements.

7. Your new heat pump compressor is equipped

with a Permanent SplitCapacitor Motor. There-

fore, ALWAYS WAIT AT LEAST THREE MIN-

UTES AFTER SHUTTING UNITOFF BEFORE

TRYING TO RESTART IT._If the unit is started

before the refrigerant pressures have a chance

to balance, the compressor motor may over-

load; and in very rare cases, blow a fuse (or tdp

a circuit breaker). Under normal operations,

this will not happen. This is most likely to occur

if a thermostat is chattering, or if the unit is

started too quickly. Do not be alarmed if this

happens. Justlet the pressure balance outand

then restart the unit.

It is a good practice when there is a power

outage (especially during severe thunder-

storms), to switchoff your unit at the thermostat

untilthe electrical power has been permanently

restored. This could prolong the life of your

compressor.

IMPORTANT- READ CAREFULLY

(This item does not apply to units equipped with scroll-type compressors).

9. Your new heat pump may contain a special compressor warming circuit to keep the compressor warm

during long off periods. Do not be alarmed if this creates a slight =hum"may or not be detectable, but is

normal.

When the power has been disconnected from the unit for longer than twelve hours, be sure to turn the

power back on twelve hoursbefore starting the unit. This will givethe compressor warming circuitachance

to operate and protect the compressor from damage.

HOW TO GET THE MAXIMUM PLEASURE FROM YOUR HEAT PUMP

In order that you may fully appreciate your heat pump, an outline of the basic principles involved are

shown in the following paragraphs.

HEATING LOAD

°/_o •

The air temperature rise from a heat pump on the heating cycle is not as great as that from afuel-fired-

fumace. The supply air coming into the room may be only 12 to 26 degrees warmer than the room air.

Therefore "hot or cold" spots are not evident in heat pump installations as they are in fuel-fired heating

systems.

Family living habits that aid the heating system, add load to the cooling system. The heater, fumace, or

boiler delivers heat into the rooms and the heat that is created within the house from electdc lights,

•cooking, the TV set, etc. help to heat rooms; therefore less heat is required from the boiler, fumace, or

unit heater.

The cooling equipment removes heat and humidity. Any additional heat released into the rooms from

these other sources will make the room air warmer and place an additional load upon the equipment.

In the case of cooking, for example, four top bumers of a gas range can produce more heat than athree

ton air condiUoner can remove. It is much more practical and economical to ventilate this concentrated

heat and moisture load than it is to dispose of it through your air conditioner. As a general rule:

Whenever you plan to have your oven or range top bumers on for more than a few minutes

during hot weather, close off the kitchen from the rest of the house, open a window or

outside door, and turn on your kitchen ventilator.

Youcanalsoeffectivelyreducethe loadonyourcoolingsystemby keepingwindowshades,blinds,or

drapesdosed or by installingawningsor canopiesduringhotweather.

Somedayswhenthe temperature is relatively high, it is comfortable because the air is dry. This is be-

cause the relative humidity is low. Other days when the temperature is about the same, it may be uncom-

fortable due to high relative humidity.

Indoor air should be both cool and relatively dry for comfort. Therefore, the cooling unit has been de-

signed to remove both heat and moisture.

THERMOSTAT SETTING

For cooling, a temperature of 75 to 78 degrees is preferred by most people. You may select a lower

temperature setting if you wish and you will probably have that temperature a good portion of the time.

However, energy use increases rapidly at the very low settings, and the equipment may have difficulty

maintaining the precise temperature.

Do not be concemed if in the evening, when the outside temperature drops below the inside temperature,

your air conditioning system is still running. The entire structure of your house has been soaldng up heat

from the sun all day long. After the sun has set there is still a tremendous amount of heat in the walls,

ceiling, roof, fumishings, etc., that must be disposed of before the air conditioner stops running. Outdoor

temperatures can drop rapidly aftersundown, while the house and its fumishings continue to give off heat

for several hours. ._

Indoor Blower and Outdoor Fan Operation: To improve the efficiency of the unit, the blower is operated

on a time delay. Depending on the outside ambient temperature, the blower may delay starting up for 5 to

•15 seconds even though the thermostat calls for cooling or heating, and when the thermostat is satisfied,

the blower may keep on running for 30 to 90 seconds longer. Do not be alarmed if you do not hear the

blower running immediately after the unit switches on. When your unit is being automatically defrosted,

the outdoor fan will stop while the unit is still running. Do not be concemed; this is a normal operation.

The fan will automatically restart after the unit has completed its defrost cycle.

Your unit is a Heat Pump. It is producing heated air on the heating cycle and cooled air on the cooling

cycle. The cooling or heating is accomplished by means of remote controls, is completely automatic, and

requires no attention after setting the thermostat to the comfort level you desire.

The heat pump is one of the most energy efficient devices for home comfort and has proven to be ex-

tremely durable and dependable through many years of use.

Your unit operates automatically by means of remote controls, and requires no attention after setting the

thermostat to the comfort level you desire.
