OUTDOOR UNIT PREPARATION
Step 4
If indoor unit refrigerant piping is going to exit from the rear:
1. It is recommended that the refrigerant pipe flare connectors extend through the wall
to the outside. In some situations field-fabricated piping extensions will be required to
extend the indoor unit refrigerant flare connections to the outside of the wall.
2. Use mounting bracket diagrams and dimensions to find and mark the proper location
for the wall hole.
If refrigerant piping is going through the right or left side of front panel:
1. Use a small saw blade to carefully cut a U-shaped hole in the side of the front panel.
The hole must be large enough for refrigerant pipes, condensate hose and wires.
2. Determine and mark proper location for wall hole.
3. Use table below to determine recommended wall hole size for your unit size.
4. Cut the wall hole with a 5° to 10°
downward slant to the outdoors.
5. Insert a wall hole sleeve into hole to
prevent damage to refrigerant pipes,
insulation, condensate drain hose
and wiring.
6. Seal around wall hole sleeve with
caulk or foam to weatherproof.

VACUUM TESTING
Step 9
Leaking Test
1. Connect the charging hose of the manifold valve to charge the end of the low-pressure valve.
2. Add dry nitrogen to a pressure of 200 lbs. Tightly close both high- and low-pressure valves.
3. Leak-test flare fittings with soap bubbles. If no leak is detected, release nitrogen.
Step 10
System Vacuum and Charge
UNIT DAMAGE HAZARD
Never use the system compressor as a vacuum pump. It may result in equipment damage
or improper system operation.
Refrigerant pipes and indoor coil should be evacuated using the recommended deep vacuum
method of 500 microns. The alternate triple evacuation method may be used if the procedure
outlined below is followed.
NOTE: Alway break a vacuum with dry nitrogen.
Using Vacuum Pump
1. Completely tighten flare nuts A, B, C, D,
connect manifold gage charge hose to a
charge port of the low side service valve.
2. Connect charge hose to vacuum pump.
3. Fully open the low side of manifold gage.
See figure at right.
4. Start vacuum pump.
5. Evacuate using either deep vacuum or triple evacuation method.
6. After evacuation is complete, fully close the low side of manifold gage and stop
operation of vacuum pump.
7. The factory charge contained in the outdoor unit is good for up to 25 ft. (8 m) of line length.
NOTE: For refrigerant lines longer than 25 ft (8 m), add add’l refrigerant per foot of extra
piping up to the maximum allowable length. See System Requirement section on page 4
for more info
8. Disconnect charge hose from charge connection of the low side service valve.
9. Fully open service valves B and A.
10. Securely tighten caps of service valves.
20
Deep Vacuum Method
The deep vacuum method requires a vacuum pump capable of pulling a vacuum of 500 microns
and a vacuum gage capable of accurately measuring this vacuum depth. The deep vacuum
method is the most positive way of assuring a system is free of air and liquid water.
