How to Install a Heat Pump Refrigeration Cycle

The installation of a heat pump refrigeration cycle should be done by a trained and preferably licensed individual. The process can be somewhat time consuming and complicated. There are codes and guidelines that must be followed in order to install this in a safe and correct manner.

1. Receive training. You should be trained in the Heating, Ventilating and Air Conditioning or, HVAC, industry before attempting to install a heat pump refrigeration cycle. There are classes you can take to receive the correct training in this field.

2. Find a location. The heat pump should be placed in a location with as little exposure to the sun as possible. There should be room to reach the inlet and discharge air openings. You should also be sure to remember to leave enough room to reach for servicing the pump.

3. Install mount pad. The mounting pad should be placed in a level and solid location about 30 inches or so from the house foundation. This will help prevent noise submissions from the pump.

4. Assembly the pump unit. All panels and slingers should be attached. The spreaders should be placed on top of the unit.

5. Remove the down flow duct cover plates and place over the horizontal duct openings.

6. Make 3/4 inch drain pipe out of PVC. It should have a trap that is about two inches from the outlet.

7. Place the trap close to the heat pump and attach the drain assembly to the unit. Make sure the drain flows in to an appropriate place for disposal.

8. Remover the blower access panel and place the shipping support away from the assembly. 

9. Mount connectors between the ducts and plenums to help reduce sounds vibrations.

10. Complete duct work according the National Fire Protection Agency guidelines and codes.

11. Place a filter in the return air inlet and route the return air duct through a filter.

12. Unhook the power supply and remove the control access place. Connect L1 and L2 copper. Ground the wiring.

13. Hook the copper wires to the access panel and splice them to the coded control board terminal.

14. Turn the power on to the unit. Test the unit after it has been powered on for about half an hour.
