INSTALLATION AND OPERATING INSTRUCTION MANUAL

HEAT PUMP - HP MODELS 1 1/2 - 5 1/2 TONS

1. INTRODUCTION

Please take a few minutes to read our instructions before you install and use yonheat pump. This will
help you obtain the full value from your unit. It will also help you avoid any needless service costs that

result from causes we cannot control and cannot cover in our guarantee.

RULES FOR INSTALLATION AND SAFE OPERATION

1. Read these rules and the instructions carefully.
Failure to follow the rules and the instructions

could cause a malfunction of the heat pump unit
resultingin injury,death and/or propertydamage.

2. Check your local codes and utilitystandards.
The installation must comply with their rules.

3. Shut off the electric oower before makino
connections on the unit or removing 0anels for

servicing. (There may be more than one

di_;connect!.

4. Referto Section VIII for maintenance procedures.

5. Do not operate this unit at outdoor temperatures

below 60"F on cooling nor above 75° on heating.

6. The components of a heat pumpmay 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 punctured. When installingor

servicing the heat pump, be extremely careful to
avoid injury.

7. The refrigerant circuitis in a closed, pressurized
system. If for any reason, the system needs to

be opened for servicing, it is imperative that both

high and low sides of the system be purged

completelyintoa recoverytank before anysection

of the tubing is cut or unbrazed.

The importance of proper installation cannot be overemphasized. The best designed unit wll appear
to operate poorly if installed improperly. Unlike the small appliance where quality of operation can

usually be determined as it leaves the factory, the performance of a heat pump depends, to a large
extent, on its installation.

Problems always occur if the installerdoes not take precautions in the following areas:

Wire Size

Duct Size
Duct Openings

Duct Insulation
Refrigerant Charge

- Inadequate wire sizes can cause an excessive voltage drop, causing the compressor
and fan motors to operate at undesirably low voltage levels.

- Inadequate duct size, elbows, distributorsor registers can restdctair flow.

- Improperly sealed ductsections can cause considerable loss in coolingcapacity due
to air leakages.

- Inadequate duct installationin attic space will cause heat gain in the system.

- Unit is precharged, but should a charge be necessary, it should be verified against
the operating system pressures, temperatures, and current draws as specified in the

catalog.

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

and only the highest quality component partsand workmanship have gone intothese heat pumps to"
make them the mostreliable inthe industry. Before a model is released for production,it undergoesa

battery of testsin environmental test rooms withtemperatures rangingfrom sub-freezing 0°F to 120°F
desert temperatures.

II. DIMENSIONS

• k

It is very important that the ducts for a serf-contained system be properly sized, installed,sealed,

and insulated for the best performance of the system. It is recommended that boththe supplyand
the retum duct be insulated (2") when installed in an unconditionedarea. Where the supplyduct

is exposed to the outdoor temperatures, vapor barrier material should be used. All duct work

shouldbe installed in accordance with ASHRAE or NAHB.

_lJ. III. POWER SUPPLY & WIRING

Pages 11, 12 & 13 show typical wiring diagrams for the various units. However, each unit will have its
appropriate wiring diagram attached to the access panel of the wiring control section. All wiring and
fusing must comply with local and national electrical code requirernents.

The 24 volt control circuit connections are made at the rightside of the panel (See fig. 1). The main
powerconnections are made at the "L"terminals ofcontractor, through knockoutinside ofunit. These

connections must be tightand elect'ricallysecure. A fused disconnect must be weather tight. When
the unit isoutdoors,the fused disconnect mustbe installedat the unit location. The fuse(s) shouldbe

dual element type. Fuse and ampacity ratingsare listedinthe table on page 3 and also on the rating
plate on the unit.

CAUTION: Unit must always be grounded with a suitable ground connection.
