Connecting of Tubing

1.Cutting and flaring of tubing:

A.Cut the tubing on its straight part with the pipe cutter.

B.Remove burrs from cut edges of pipes, which may cause a gas leak.

C.Flaring of the pipe is done with the flaring tool.

NOTE: Do not forget to install the flare nut before flaring

2.Pre-Connecting:

Screw the tubing turning

3 to 5 times until hand tight.

3. Fastening:

Fasten the connection.

Air Purge and Charging

!CAUTION !

1)Remove the cap from the service port on the suction line service valve.

2)Connect the suction side of the refrigerant gauge manifold to the Suction Line service valve. Connect the center hose of the refrigerant manifold gauge to the micron gauge. Connect the other side of the micron gauge to the vacuum pump. (Diagram 1)

3)Open the suction side of the refrigerant manifold set and turn the vacuum pump on. NOTE: Evacuate the system down to

400 microns.

4)When the system pulls down to 400 microns turn the vacuum pump off. Observe the micron gauge: if the system has a leak the gauge will detect it. If there is a leak, find it, repair it, and repeat steps 3 and 4.

5)Close the refrigerant gauge manifold valve and disconnect the vacuum pump from the system.

6)Remove the Suction and Liquid line Service Valve Caps from the valves.

7)Using an Allen wrench, open the Liquid Line Service Valve until the valve is in the fully open position. Next do the same for the

Suction Line Service valve. NOTE: Be careful as not to completely remove the valve core from the valve. This will result in the release of refrigerant from the system into the atmosphere!

8)Re-install the caps on both service valves. This completes the charging of the system.

Outdoor Unit (Heat Pump Only)

NOTE: Allow clearance for drainage of water or condensate.

For outdoor condensation:

The outdoor unit has drain outlets on the base to drain condensation to the outside.

To drain condensation by hose (5/8” hose) with the drain socket, connect the socket to the center of the base and cover all other outlets with base caps.

Install the outdoor unit on a flat level surface and make sure condensation drains smoothly.

In cold areas, condensation

and defrost water can freeze, therefore do not use the drain outlet caps during the cold season.

• Electrical connection should only be made by a qualified professional.
