Step 3—Mounting the Air Conditioner On the Bracket

1. Remove the air conditioner front panel and air intake grille, as

shown in Fig. 5.

2. Fasten the left and right side strips to the air conditioner using

6 sheet metal screws, as shown in Fig. 19. Ensure that:

a. The wide side of the strip is located at the bottom of the air

conditioner.

b. The strip angle faces inward.

3. Mount the indoor unit on the bracket. Slide the protruding

parts of the side strips onto the ceiling bracket so that the 4

safety screw holes on the left and right strips align with those

on the ceiling bracket.

4. Make sure that the air conditioner is tilted slightly toward the

drainage outlet on the right side. Use water to test for proper

drainage. Fix the tilt by adjusting the height of the right strip

relative to the left one.

5. Fasten the air conditioner to the ceiling bracket using the 4

side screws. (See Fig. 20.)

Step 4—Continuing the Installation

After attaching the air conditioner to the ceiling bracket, continue

the installation procedure in the previous section, titled

“Drainage.”

NOTE: If the drainage is routed in direction no. 1, as shown in

Fig. 16, cut out the oval opening in the air intake opening for the

drainage tube and route the tube through the air intake grille. (See

Fig. 21.)

NOTE: Set DIP switch no. 1 to the “ON” position. (See Fig. 11.)

The other factory switches are set at the factory and should not be

changed.

Step 5—Installing the Outdoor Unit

1. The outdoor unit must be installed on a solid surface.

2. Make sure that the unit is level.

3. Fasten the outdoor unit legs to the base, as shown in Fig. 14.

Place the rubber absorption cushions (supplied with the

outdoor unit) under the unit’s legs to prevent vibrations.

WIRING THE OUTDOOR UNIT

1. Remove the outdoor unit plastic side cover.

2. Loosen the screws on the terminal block.

3. Attach the electrical terminals supplied to the inter-unit

control and power cable wires.

4. Connect the wires to the terminal block, in accordance with

the coding which appears in Fig. 15.

5. Connect the outdoor sensor cable, making sure the connector

is properly inserted.

6. Secure the inter-unit electric and sensor cable to the outdoor

unit with the clamp shown in Fig. 14.

7. Reassemble the plastic side cover.

NOTE: A drainage tube can be connected to the outdoor unit to

remove condensation formed during heating mode operation.

Make sure that all screws and wires are properly fastened.

Loose wires or connections can cause damage and present a

fire hazard.

Step 6—Connecting the Refrigerant Lines

1. To connect the refrigerant lines, use only “L” type sealed,

dehydrated copper refrigerant tubing. No other type of tubing

may be used. Use of other types of tubing will void the

manufacturer’s warranty.

2. Do not open service valves or remove protective caps from

tubing ends until all the connections are made.

3. Take care to avoid kinks or flattening of the tubing.

4. Bend tubing with special bending tools to avoid the formation

of sharp bends.

5. Keep the tubing free of dirt, sand, moisture, and other

contaminants to avoid damaging the refrigerant system.

6. Avoid sags in the suction line to prevent the formation of oil

traps.

7. Insulate the tubing with 3/8-in. walled thermal pipe insulation.

Inserting the tubing into the insulation before making the

connections will save time and improve installation. The

suction and liquid lines should never come in direct contact.

FLARING AND CONNECTING

1. Remove the protective cap from the flare fitting.

2. Remove the protective cap from the tubing and cut to the

required length. Make sure that the cut is perpendicular and

clean, without burrs.

3. Slip the flare nut on the tubing and flare the tube end, using

standard flaring tools.

4. Tighten the nut until resistance is met. Mark the nut and the

fitting. Using a suitable wrench tighten an additional 1/4 turn.

Use the following specified torque, according to connection

size:

Liquid line:

1/4-in. - (12.3 ft/lb)

3/8-in. - (29 ft/lb)

Suction line:

1/2-in. - (36 ft/lb)

5/8-in. - (47 ft/lb)

3/4-in. - (72 ft/lb)

5. The valves on the outdoor unit must remain closed until all

four connections have been made.

Step 7—Air Vacuum and Refrigerant Charge

When all the fittings are connected, air must be expelled, as

follows:

1. Open the service port cap on the suction line valve (large

valve).

2. Connect the vacuum pump to the service port via the pressure

gauge and operate the pump for 15 minutes.

3. Make sure that full vacuum is present and disconnect the

vacuum pump.
