HEAT PUMP INSTALLATION General Information
Split system heat pumps are designed only for outdoor rooftop or ground level installations. This unit has been tested for capacity and efficiency in accordance with AHRI Standards and will provide many years of safe and dependable comfort, providing it is properly installed and maintained. Abuse, improper use, and/or improper maintenance can shorten the life of the appliance and create unsafe hazards.
To achieve optimum performance and minimize equipment failure, it is recommended that periodic maintenance be performed on this unit. The ability to properly perform maintenance on this equipment requires certain mechanical skills and tools.
Before You Install the Heat Pump
√The cooling load of the area to be conditioned must be calculated and a system of the proper capacity selected. It is recommended that the area to be conditioned be completely insulated and vapor sealed.
√Check the electrical supply and verify the power supply is adequate for unit operation.The system must be wired and provided with circuit protection in accordance with local building codes.If there is any question concerning the power supply, contact the local power company.
√The indoor section (air handler, furnace, etc) should be installed before routing the refrigerant tubing. Refer to the indoor unit's installation instructions for installation details.
√All units are securely packed at the time of shipment and upon arrival should be carefully inspected for damage prior to installing the equipment at the job site. Verify coil fins are straight. If necessary, comb fins to remove flattened or bent fins. Claims for damage (apparent or concealed) should be filed immediately with the carrier.
√Please consult your dealer for maintenance information and availability of maintenance contracts. Please read all instructions before installing the unit.
Locating the Heat Pump
•Survey the job site to determine the best location for mounting the outdoor unit.
•Overhead obstructions (Figure 1), poorly ventilated areas, and areas subject to accumulation of debris should be avoided.
•Sufficient clearance for unobstructed airflow through the outdoor coil must be maintained in order to achieve rated performance. See Figure 1 for minimum clearances to obstructions.
•Consideration should be given to availability of electric power, service access, noise, and shade.
Packaging Removal
To prevent damage to the tubing onnections, carefully remove the carton and user’s manual from the equipment.
Discard the shipping carton.
Ground Level
Ground level installations must be located according to local building codes or ordinances and these requirements:
•Clearances must be in accordance with those shown in Figure 1.
•A suitable mounting pad must be provided and be separate from the building foundation. The pad must be level and strong enough to support the unit’s weight. The slab height must be a minimum of 2” (5 cm) above grade and with adequate drainage. See Figure 1.
Rooftop
•The method of mounting should be designed so that it does not overload roof structures or transmit noise to the interior of the structure.The roof must be structurally capable of handling the weight of the unit.
•Full perimeter support is required under the unit.
Support must be made of weather resistant materials and installed prior to unit installation.
•The support must be built to raise the unit 6" above the roof.
