7. Allow 18 minimum for service access to the compressor com partment and controls The top of the unit should be completely unobstructed If units are to be located under an overhang there should be a minimum of 36 clearance and provisions made to deflect the warm discharge air out from the overhang 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 sub freezing temperatures Heat pump unit bases have holes under the outdoor coil to permit drainage of defrost water accumulation The unit must be situated to permit free unobstructed drainage of the defrost water and ice A minimum 2 clearance under the outdoor coil is required in the milder climates Grounb LeveL PRE INSTALLATION DETAILS The unit should be set on a solid level foundation preferably a concrete slab at least 4 inches thick The slab should be above ground level and surrounded by a graveled area for good drainage Any slab used as a unit s foundation should not adjoin the building as it is possible that sound and vibration may be transmitted to the structure
8. Since the temperature of the refrigerant in the outdoor coil on the heating cycle is generally below freezing point frost forms on the surfaces of the outdoor coil under certain weather conditions of temperature and relative humidity Therefore it is necessary to reverse the flow of the refrigerant to provide hot gas in the outdoor coil to melt the frost accumulation This is accomplished by re versing the heat pump to the cooling cycle At the same time the outdoor fan stops to hasten the temperature rise of the outdoor coil and lessen the time required for defrosting The indoor blower continues to run and the supplementary heaters are energized DEFROST CONTROL During operation the power to the circuit board is controlled by a temperature sensor which is clamped to a feeder tube entering the outdoor coil Defrost timing periods of 30 60 and 90 minutes may be selected by setting the circuit board jumper to 30 60 and 90 respectively Accumulation of time for the timing period selected starts when the sensor closes approximately 31 F and when the wall thermostat calls for heat At the end of the timing period the unit s defrost cycle will be initiated provided the sensor re mains closed When the sensor opens approximately 75 F the defrost cycle is terminated and the timing period is reset If the defrost cycle is not terminated due to the sensor temperature a twelve minute override interrupts the unit s defrost period
