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 resulting in injury,death and/or property damage.
2.Check your local codes and utility standards. 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 pump 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 punctured. When installing or 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 completely intoa recovery tank before any section 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 installer does not take precautions in the following areas:
Wire | Size | - Inadequate wire sizes can cause an excessive voltage drop, causing the compressor |
|
| and fan motors to operate at undesirably low voltage levels. |
Duct | Size | - Inadequate duct size, elbows, distributors or registers can restdct air flow. |
Duct | Openings | - Improperly sealed duct sections can cause considerable loss in cooling capacity due |
|
| to air leakages. |
Duct Insulation | - Inadequate duct installation in attic space will cause heat gain in the system. | |
Refrigerant Charge | - 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 parts and workmanship have gone into these heat pumps to" make them the most reliable in the industry. Before a model is released for production, it undergoes a battery of tests in environmental test rooms with temperatures ranging from
