Rooftop Installation Rooftop platform requirements: - The unit MUST be situated to provide safe access for servicing. - The existing roof structure MUST be adequate to support the weight of the unit or the roof MUST be reinforced. Check the weight of the unit in relation to the roof structure and local building codes or ordinances and reinforce roof structure if necessary. See the last page of this manual for unit weights. outlet from trap MUST be at least 1" (25.4mm) below top of outlet from unit.
All exposed wiring and connections MUST be made with weatherproof cable or wire unless installed in conduit. FIGURE 4 Diagram I Connection ElectronicThermostat Low Voltage Electronic Thermostat Subbase LowVoltage Wiring Low voltage connections are made on the electronic control board inside the electrical control compartment (see FIGURE 5). For access, remove the electrical control access panel).
and located, MUST NOT exceed the temperature limitations for type T wire and MUST be installed according to the manufacturer's instructions for the devices. Converting 230V Units to 208V To convert 230V units to 208V: Final ElectricalCheck 1. Turn electric power OFF. 2. Remove the electrical access panel. 3. Locate the 24V control transformer. 4. Remove wires from the terminal labeled "240V" on the 24V control transformer and reconnect them to the 208V terminal of the 24V control transformer. 5.
Air DistributionSystem For airflow data (blower performance data, blower speed tap settings, etc.) see the Parts List. Ductwork NOTE: The total heat gain/heat loss from the structure as expressed in total Btu/hr MUST be calculated by manufacturer's method or in accordance with "A.S.H.R.A.E. Guide" or "Manual J - Load Calculations" published by the Air Conditioning Contractors of America or in Canada"H.R.A.I. Residential Heating and Cooling Load Calculation Manual.

To adjust defrost interval: Turning The Unit Off Set the thermostat selector switch to OFF and set the Turn off all power to Heat Pump. 1. fan switch to AUTO. To restart, set thermostat selector switch to COOL and set thermostat to temperature desired. 2. Remove control box cover. 3. Locate electronic control board. 4. The Control Board has a jumper that allows you to change the defrost time interval.
Maintenance Air Filters, Condenser Coil and Condensate Drain Maintenance Refer to Home Owners Manual supplied with your heat pump for information on filter sizes, condenser coil clearances from allowances. shrubbery and condensate drainage CAUTION Do NOT operate unit without filters in place. Inspect filters monthly and clean and/or replace as needed. RefrigerationAccess Ports This unit is equipped with refrigeration access ports mounted on the side of the unit.
FIGURE 11 Wire Colors 8@ @@ 16b CirculatingAir Blower Visually inspect the blower wheel for accumulations of dirt or lint. Clean the compartment and the blower wheel. If accumulation is excessive on blower wheel, or does not easily remove, it will be necessary to remove the blower assembly. CAUTION Do NOT use 3 in 1 oil, penetrating oil, WD40 or similar oils to oil motor bearings. Oil the blower motor by adding 1/2 teaspoonful (lcc) of SAE 10W30 to each motor bearing.
