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.

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 sub-freezing 0°F to 120°F desert temperatures. -1 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 both the supply and theretumductbeinsulated(2")wheninstalledinanunconditionedarea.
