•Refer to the OCT03
REVISED EDITION-C
as for control relation.
This manual does not
cover outdoor units.
When serving them,
please refer to the
service manual
No.OC180 REVISED
EDITION-A, OC261 and
this manual in a set.
● Outdoor units which are connected to PSH-P·GAH1 and PSA-P·GA1 have been added.
● ROOM TEMPERATURE THERMISTOR has changed because it has made the lead wire longer in order to improve work
efficiency.
● FAN MOTOR CAPACITOR has changed because it no longer meets the criteria of UL Standards.
● FAN GUARD has changed because it has become an individual part, which was once specified as a part combined with
BELL MOUTH.
● The parts No. of REMOTE CONTROLLER has changed.
(The following parts numbers are interchangeable.)

SAFETY PRECAUTION
Cautions for using with the outdoor unit which adopts R407C refrigerant.
· Do not use the existing refrigerant piping.
-The old refrigerant and refrigerant oil in the existing piping contains a large amount of chlorine which may cause the refrigerant oil of the new unit to deteriorate.
· Do not use copper pipes which are broken, deformed or discolour .
In addition, be sure that the inner surfaces of the pipes are clean, free of hazardous sulphur and oxides, or have no dust /
dirt, shaving particles, oils, moisture or any other contamination.
-If there is a large amount of residual oil (hydraulic oil, etc.) inside the piping and joints, deterioration of the refrigerant oil will
result.
· Store the piping to be used during installation indoors and keep both ends of the piping sealed until just before
brazing. (Store elbows and other joints in a plastic bag.)
-If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and compressor trouble may result.
· Use ester oil, ether oil or alkyl benzene (small amount) as the refrigerant oil to coat flares and flange connections.
-The refrigerant oil will degrade if it is mixed with a large amount of mineral oil.
Use liquid refrigerant to fill the system.
-If gas refrigerant is used to fill the system, the composition of the refrigerant in the cylinder will change and performance
may drop.
· Do not use a refrigerant other than R407C.
-If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may cause the refrigerant oil to deteriorate.
· Use a vacuum pump with a reverse flow check valve.
-The vacuum pump oil may flow back into the refrigerant cycle and cause the refrigerant oil to deteriorate.
· Do not use the following tools that are used with conventional refrigerant.
(Gauge manifold , charge hose, gas leak detector, reverse flow check valve, refrigerant charge base, vacuum gauge,
refrigerant recovery equipment)
-If the conventional refrigerant and refrigerant oil are mixed in the R407C, the refrigerant may deteriorated.
-If water is mixed in the R407C, the refrigerant oil may deteriorate.
-Since R407C does not contain any chlorine, gas leak detectors for conventional refrigerant will not react to it.
· Do not use a charging cylinder.
-Using a charging cylinder may cause the refrigerant to deteriorate.
· Be especially careful when managing the tools.
-if dust, dirt, or water gets in the refrigerant cycle, the refrigerant may deteriorate.
· Do not use the drier which is sold in the field.
-The drier for R407C refrigerant is per-attached to outdoor unit refrigerant circuit.
-Some drier in the field are not in conformity with R407C refrigerant .

8Refrigerant recovery equipment.
[2] Notice on repair service
·After recovering the all refrigerant in the unit, proceed to working.
·Do not release refrigerant in the air.
·After completing the repair service, recharge the cycle with the specified amount of
liquid refrigerant.
[3] Refrigerant recharging
(1) Refrigerant recharging process
1Direct charging from the cylinder.
·R407C cylinder are available on the market has a syphon pipe.
·Leave the syphon pipe cylinder standing and recharge it.
(By liquid refrigerant)
(2) Recharge in refrigerant leakage case
·After recovering the all refrigerant in the unit, proceed to working.
·Do not release the refrigerant in the air.
·After completing the repair service, recharge the cycle with the specified amount of
liquid refrigerant.

Connection method
Note 1. How to connect refrigerant pipes.
Factory supplied optional refrigerant pipings contain refrigerant at the above atmospheric pressures.
As long as connection takes no more than 5 minutes, no air will enter, and there will be no need for
air purging.
Remove the blind caps and make the connections within 5 minutes. After the connections for the
indoor and outdoor units are made, open the stop valve on the outdoor unit to allow refrigerant gas
to flow.
If piping length exceeds 5m, an additional charge of refrigerant is needed.
Note 2. The following main parts are contained in the optional refrigerant piping kit.
Allows individual or combined control of up to 16 units. When using this controller, a program timer adapter (PAC-825AD) is
also needed.
Part No.PAC-805RC
3. PROGRAM TIMER ADAPTER
This adapter is needed when a centralized remote controller (PAC-805RC) is used.
Part No.PAC-825AD
4. TIMER ADAPTER
This adapter is needed for system control and for operation via external contacts.
Part No.PAC-SA89TA-E
5. MULTIPLE REMOTE CONTROLLER ADAPTER
