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.
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 the retum duct be insulated (2") when installed in an unconditioned area. Where the supply duct is exposed to the outdoor temperatures, vapor barrier material should be used. All duct work should be installed in accordance with ASHRAE or NAHB. I I / HP MODELS Fig.

4 Normally, the unit is installed outdoors either on the roof or ground, where practical. In normal roof installation, the unit is placed on an angle iron frame, and where required in some instances, isolated from the frame with rubber, cork or spdng mounts. These mounts are to help eliminate vibration and noise. Ground installation is basically the same for both self-contained units and split-system outdoor -units.Locate the unit on a concrete slab or blocks not connected to the buildings foundation.
COMPONENTS SCROLL WITH SPECIAL FEATURES: 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. On three phase compressor, incorrect phase sequence will result in the compressor running backwards. CAUTION: Never use the scroll compressor to pump itself down (create a vacuum) by closingoff the suction line.
Check the voltage at the compressor motorconnections. If the voltage is 5% below or 10% above the rated voltage or there is a d'dferencegreater than 3% between phases, shut down the system and call the power company. A failure to do so may cause damage to the equipment. g After the unit is in operation, it will take about 30 minutes runningtime to stabilize the system. . 4.
4. A field check-out of the defrost control board can be made by the following steps: 1. Attach a "jumper"wire across the two terminals of the sensor wires (see wiring diagrams on pages 11 through 14 showing the sensor being wired to the =COM" terminal of the defrost control board). = 1 Attach a "jumper" wire across the two "TST" terminals. The timing cycles are divided by a factor of 256. (e.g. 90 minutes is reduced to 21.1 seconds, 60 minutes to 14 seconds and 30 minutes to 7 seconds).
Vl. ELECTRICAL COOUNG OPERATION CYCLE With the disconnect on "ON" position, voltage is supplied to the primary of the control transformer and crankcase heater. The control transformer reduces the voltage from 230 or 208 to 24 volts for the low voltage and the thermostat circuit. With a single-stage cool/single-stage heat t_Lh_mostat set in the cooling _o_ition, current is supplied from one side of the 24 volt secondary of the control transformer to the "R" terminal of the thermostat.
VIII. OPERATION AND MAINTENANCE II thermostat is chattering, or if the uoit is started too quickly. Do not be alarmed ifthis happens. Just let the pressures balance out and then start the unit. 1. Be sure the filter is clean. Inspect every 30 days of operation; if obstructed, clean or replace filter at once. DO NOT RUN WITHOUT A FILTER. 2. Always let the thermostat control the operation of the system. Never try to "second guess" the thermostat, or tamPer with it.
Any residential THERMOSTAT within the house from electric lights, cooking, the TV set, etc. helps to heat the rooms therefore, that much less heat is required from the b_lsr, furnace, or heat pump. For cooling, a temperature of 75 to 78 degrees is preferred by most people. You may select lower temperature setting if you wish and you will probably have that temperature a good portion of the time.
