ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal
injury or death.

Before installing, modifying, or servicing system, main
electrical disconnect switch must be in the OFF
position. There may be more than 1 disconnect switch.
Lock out and tag switch with a suitable warning label.

!

EQUIPMENT DAMAGE HAZARD

Failure to follow this caution may result in equipment
damage or improper operation.

Do not bury more than 36 in. (914 mm) of refrigerant pipe
in the ground. If any section of pipe is buried, there must be
a 6 in. (152 mm) vertical rise to the valve connections on
the outdoor units. If more than the recommended length is
buried, refrigerant may migrate to the cooler buried section
during extended periods of system shutdown. This causes
refrigerant slugging and could possibly damage the
compressor at start−up.

Piping Guide:

S Do not open service valves or remove protective caps from tubing

ends until all the connections are made.

S Bend tubing with bending tools to avoid kinks and flat spots.
S Keep the tubing free of dirt, sand, moisture, and other contaminants

to avoid damaging the refrigerant system.

S Avoid sags in the suction line to prevent the formation of oil

traps.

Insulate each tube with minimum 3/8−in. (10 mm) wall thermal pipe
insulation.

Inserting the tubing into the insulation before making the

connections saves time and improves installation quality.

1. Remove service valve cover if provided with unit.

2. Cut tubing with tubing cutter.

3. Install correct size flare nut onto tubing and make flare
connection.

4. Apply a small amount of refrigerant oil to the flare connection
on the tubing.

5. Properly align tubing in with service valve.

6. Tighten flare nut and finish installation using two wrenches as
shown in Fig. 9.

CAUTION

UNIT DAMAGE HAZARD

Failure to follow this caution may result in equipment
damage or improper operation.

Never use the system compressor as a vacuum pump.

Refrigerant tubes 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. Always break a vacuum with dry nitrogen.

SYSTEM VACUUM AND CHARGE

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 (see
Fig. 16.)

2. Connect charge hose to vacuum pump.

3. Fully open the low side of manifold gage (see Fig. 17).

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. For refrigerant lines longer than 25
ft (8 m), add 0.2 oz. per foot of extra piping up to the maximum
allowable length.

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.

Triple Evacuation Method

The triple evacuation method should only be used when vacuum pump
is only capable of pumping down to 28 in. of mercury vacuum and
system does not contain any liquid water.
Refer to Fig. 19 and proceed as follows:

1. Pump system down to 28 in. of mercury and allow pump to con­tinue operating for an additional 15 minutes.

2. Close service valves and shut off vacuum pump.

3. Connect a nitrogen cylinder and regulator to system and open
until system pressure is 2 psig.

4. Close service valve and allow system to stand for 1 hr. During
this time, dry nitrogen will be able to diffuse throughout the
system absorbing moisture.

5. Repeat this procedure as indicated in Fig. 19. The system is then
free of any contaminants and water vapor.
