EPA REGULATIONS WARNING MAY CAUSE SERIOUS ILLNESS OR DEATH AND WHICH ARE KNOWN TO THE IMPORTANT: THE UNITED STATES ENVIRONMENTAL PROTECTION AGENCY (EPA) HAS ISSUED VARIOUS REGULATIONS REGARDING THE INTRODUCTION AND DISPOSAL OF REFRIGERANTS IN THIS UNIT. FAILURE TO FOLLOW THESE STATE OF CALIFORNIA TO CAUSE CANCER, BIRTH DEFECTS OR OTHER REGULATIONS MAY HARM THE ENVIRONMENT AND CAN LEAD TO THE IMPOSITION REPRODUCTIVE HARM. OF SUBSTANTIAL FINES.

UNIT LOCATION Consider the affect of outdoor fan noise on conditioned space and any adjacent occupied space. It is recommended that the unit be placed so that condenser air discharge does not blow toward windows less than 25 feet away. Consideration should also be given to shade and unit appearance. Heat pumps require special location consideration in areas of heavy snow accumulation and/or areas with prolonged continuous subfreezing temperatures.
PAGE 5
CAUTION TO AVOID POSSIBLE PERSONAL INJURY, A SAFE, FLAT SURFACE FOR SERVICE PERSONNEL SHOULD BE PROVIDED. IMPORTANT: If using bottom discharge with roof curb, duct work should be attached to the curb prior to installing the unit. Return Lower unit carefully onto roof mounting curb. While rigging unit, center of gravity will cause condenser end to be lower than supply air end.
PAGE 6
When installing filters, ensure the air flow arrows on the filter are pointing toward the circulator blower. Fuses smaller than that recommended on the rating plate could result in unnecessary fuse failure or service calls. The use of protective devices of larger size than indicated could result in extensive damage to the equipment. The manufacturer bears no responsibility for damage caused to equipment as result of the use of larger than is recommended size protective devices.

3. Slowly raise the heating temperature setting. When the heating first stage makes contact, stop raising the temperature setting. The compressor, blower and fan should now be running with the reversing valve in the de-energized (heating) position. After giving the unit time to settle out, make sure the unit is supplying heated air. COMPONENTS CRANKCASE HEATER This item is “ON” whenever power is supplied to the unit and the crankcase heater thermostat is closed.
PAGE 9
When the heat pump is in the heating cycle, the outdoor coil is functioning as an evaporator. The temperature of the refrigerant in the outdoor coil must be below the temperature of the outdoor air in order to extract heat from the air. Thus, the greater the difference in the outdoor temperature and the outdoor coil temperature, the greater the heating capacity of the heat pump. This phenomenon is a characteristic of a heat pump.

8. The control is shipped from the factory with the compressor delay option selected. This will de-energize the compressor contactor for 30 seconds on defrost initiation and defrost termination. If the jumper is set to Normal, the compressor will continue to run during defrost initiation and defrost termination. The control will also ignore the low pressure switch connected to R-PS1 and PS2 for 5 minutes upon defrost initiation and 5 minutes after defrost termination.

REFRIGERANT CHARGE CHECKS SATURATED LIQUID PRESSURE TEMPERATURE CHART After completing airflow measurements and adjustments, the unit’s refrigerant charge must be checked. All package units are charged to the superheat method at the compressor suction line (for fixed orifice devices). After superheat is adjusted it is recommended to check unit subcooling at the condenser coil liquid line out. For charge adjustments, see superheat and subcooling charts shown for each model.

PACKAGE UNITS - HEAT PUMP AND AC UNITS HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS We strongly recommend a bi-annual maintenance checkup be performed by a qualified service agency before the heating and cooling seasons begin. An alternate cleaning method is to use one of the products listed in the technical publication TP-109 (shipped in the literature bag with the unit) to clean the coils. The cleaners listed are the only agents deemed safe and approved for use to clean round tube aluminum coils.
