6. Refrigerant piping work

6.4. Purging procedures leak test

PURGING PROCEDURES

Connect the refrigerant pipes (both the liquid and gas pipes) between the indoor
and the outdoor units.

Remove the service port cap of the stop valve on the side of the outdoor unit gas pipe.
(The stop valve will not work in its initial state fresh out of the factory (totally closed
with cap on).)

Connect the gage manifold valve and the vacuum pump to the service port of the
stop valve on the gas pipe side of the outdoor unit.

Run the vacuum pump. (Vacuumize for more than 15 minutes.)

Check the vacuum with the gage manifold valve, then close the gage manifold valve,
and stop the vacuum pump.

Leave it as is for one or two minutes. Make sure the pointer of the gage manifold
valve remains in the same position. Confirm that the pressure gage show -0.101MPa
(-760 mmHg).

Pipe length :

7 m [23 ft] maximum

No gas charge is needed.

Pipe length exceeding 7 m [23 ft]

Charge the prescribed

amount of gas.

Remove the gage manifold valve quickly from the service port of the stop valve.

After refrigerant pipes are connected and evacuated, fully open all stop valves on
gas and liquid pipe sides.
Operating without fully opening lowers the performance and causes trouble.

Tighten the cap to the service port to obtain the initial status.

Retighten the cap

Leak test

6.5. Drain piping work

• Ensure that the drain piping is downward (pitch of more than 1/100) to the outdoor

(discharge) side. Do not provide any trap or irregularity on the way.

• Ensure that any cross-wise drain piping is less than 20 m [65 ft] (excluding the

difference of elevation). If the drain piping is long, provide metal braces to prevent
it from waving. Never provide any air vent pipe. Otherwise drain may be ejected.

• Use a hard vinyl chloride pipe O.D. ø32 mm [1-1/4 in] for drain piping.
• Ensure that collected pipes are 10 cm [3-15/16 in] lower than the unit body’s drain

port.

• Do not provide any odor trap at the drain discharge port.
• Put the end of the drain piping in a position where no odor is generated.
• Do not put the end of the drain piping in any drain where ionic gases are generated.

(The drain hose must not be bent more than 45° to prevent the hose from breaking
or clogging.)
(Attach the hose with glue for the hard vinyl chloride pipe, and fix it with the band
(accessory).)

2.Attach the drain pipe (O.D. ø32 mm [1-1/4 in] PVC TUBE, field supply).

(Attach the pipe with glue for the hard vinyl chloride pipe, and fix it with the band
(accessory).)

3.Perform insulation work on the drain pipe (O.D. ø32 mm [1-1/4 in] PVC TUBE) and

on the socket (including elbow).

4.Check the drainage. (Refer to [Fig. 6-13])
5.Attach the insulating material (accessory), and fix it with the band (accessory) to

insulate the drain port.

Be sure to use non-oxidative brazing for brazing to ensure that no foreign
matter or moisture enter into the pipe.

Provide a metal brace to support the refrigerant pipe so that no load is
imparted to the indoor unit end pipe. This metal brace should be provided
50 cm [19-11/16 in] away from the indoor unit’s flare connection.
