SAFETY PRECAUTION
3-1. ALWAYS OBSERVE FOR SAFETY
Before obtaining access to terminal, all supply
circuits must be disconnected.
3-2. CAUTIONS RELATED TO NEW REFRIGERANT
Cautions for units utilizing refrigerant R407C
Do not use the existing refrigerant piping.
Use liquid refrigerant to seal the system.
The old refrigerant and lubricant in the existing piping
contains a large amount of chlorine which may cause the
lubricant deterioration of the new unit.
If gas refrigerant is used to seal the system, the composition
of the refrigerant in the cylinder will change and performance
may drop.
Use “low residual oil piping”
Do not use a refrigerant other than R407C.
If there is a large amount of residual oil (hydraulic oil, etc.)
inside the piping and joints, deterioration of the lubricant
will result.
If another refrigerant (R22, etc.) is used, the chlorine in the
refrigerant may cause the lubricant deterioration.
Store the piping to be used during installation
indoors with keep both ends 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 , ETHER or HAB as the lubricant to
coat flares and flange connection parts.
If large amount of mineral oil enter, that can cause
deterioration of refrigerant oil etc.
Downloaded from AC-Manual.com Manuals
3
Use a vacuum pump with a reverse flow check valve.
The vacuum pump oil may flow back into the refrigerant
cycle and cause the lubricant deterioration.
Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.
[1] Cautions for 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.
[2] 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)
Unit
Gravimeter
(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.

CAUTIONS RELATED TO NEW REFRIGERANT
Cautions for units utilizing refrigerant R410A
Use new refrigerant pipes.
Do not use refrigerant other than R410A.
In case of using the existing pipes for R22, be careful with
the followings.
· For PR60/71VHA3 and RP100 be sure to perform
replacement operation before test run.
· Change flare nut to the one provided with this product.
Use a newly flared pipe.
· Avoid using thin pipes.
If other refrigerant (R22 etc.) is used, chlorine in refrigerant can cause deterioration of refrigerant oil etc.
Make sure that the inside and outside of refrigerant piping is clean and it has no contamination
such as sulfur hazardous for use, oxides, dirt,
shaving particles, etc.
In addition, use pipes with specified thickness.
Contamination inside refrigerant piping can cause deterioration of refrigerant oil etc.
Use a vacuum pump with a reverse flow check
valve.
Vacuum pump oil may flow back into refrigerant cycle and
that can cause deterioration of refrigerant oil etc.
Use the following tools specifically designed for
use with R410A refrigerant.
The following tools are necessary to use R410A refrigerant.
Gauge manifold
Charge hose
Gas leak detector
Torque wrench
Tools for R410A
Flare tool
Size adjustment gauge
Vacuum pump adaptor
Electronic refrigerant
charging scale
Store the piping to be used during installation
indoors and keep both ends of the piping sealed
until just before brazing. (Leave elbow joints, etc.
in their packaging.)
Keep the tools with care.
If dirt, dust or moisture enter into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
If dirt, dust or moisture enter into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
Use ester oil, ether oil or alkylbenzene oil (small
amount) as the refrigerant oil applied to flares
and flange connections.
If large amount of mineral oil enter, that can cause deterioration of refrigerant oil etc.
Do not use a charging cylinder.
If a charging cylinder is used, the composition of refrigerant will change and the efficiency will be lowered.
Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.
Charge refrigerant from liquid phase of gas
cylinder.
If the refrigerant is charged from gas phase, composition
change may occur in refrigerant and the efficiency will be
lowered.
[1] Cautions for service
(1) Perform service after collecting the refrigerant left in unit completely.
(2) Do not release refrigerant in the air.
(3) After completing service, charge the cycle with specified amount of refrigerant.
(4) When performing service, install a filter drier simultaneously.
Be sure to use a filter drier for new refrigerant.
[2] Additional refrigerant charge
When charging directly from cylinder
· Check that cylinder for R410A on the market is syphon type.
· Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.)

NOTES:
1. Since the outdoor side electric wiring may change be sure to check the outdoor unit electric wiring for servicing.
2. Indoor and outdoor connecting wires are made with polarities, make wiring matching terminal numbers (S1, S2, S3).
3. Make sure that the main power supply of the booster heater is independent.
4. Symbols used in wiring diagram above are,
: Connector,
: Terminal (block).
+1. When work to supply power separately to Indoor and Outdoor unit was applied, refer to Fig 1.

TROUBLESHOOTING
10-1. TROUBLESHOOTING
<Error code display by self-diagnosis and actions to be taken for service (summary)>
Present and past error codes are logged and displayed on the wired remote controller or controller board of outdoor unit.
Actions to be taken for service and the trouble reoccurrence at field are summarized in the table below. Check the contents
below before investigating details.
Unit conditions at service
Error code
Actions to be taken for service (summary)
Displayed
Judge what is wrong and take a corrective action
according to “SELF-DIAGNOSIS ACTION TABLE” (10-3).
The trouble is reoccurring.
Not displayed
Consider the temporary defects such as the work of
protection devices in the refrigerant circuit including
compressor, poor connection of wiring, noise and etc.
Re-check the symptom, and check the installation
environment, refrigerant amount, weather when the
trouble occurred, matters related to wiring and etc.
Reset error code logs and restart the unit after finishing
service.
There is no abnormality in electrical component,
controller board, remote controller and etc.
Logged
The problem is not reoccurring.
Re-check the abnormal symptom.
Conduct troubleshooting and ascertain the cause of the
trouble according to “TROUBLESHOOTING
BY INFERIOR PHENOMENA ” (10-4).
Continue to operate unit for the time being if the cause
is not ascertained.
There is no abnormality concering of parts such as
electrical component, controller board, remote controller
and etc.

During the emergency operation the indoor unit is as follows;
(1) Indoor fan high speed operation
(2) Drain-up machine operation(Option)
2. When emergency operating for COOL or HEAT, setting of the switch (SWE) in the indoor controller board and outdoor unit
emergency operation are necessary.
3. Check items and notices as the emergency operation
(1) Emergency operation cannot be used as follows;
• When the outdoor unit is something wrong.
• When the indoor fan is something wrong.
• When drain over flow protected operation is detected during self-diagnosis. (Error code : P5)
(2) Emergency operation will be serial operation by the power supply ON/OFF.
ON/OFF or temperature, etc. adjustment is not operated by the remote controller.
(3) Do not operate for a long time as cold air is blown when the outdoor unit starts defrosting operation during heat emergency operation.
(4) Cool emergency operation must be within 10 hours at most. It may cause heat exchanger frosting in the indoor unit.
(5) After completing the emergency operation, return the switch setting, etc. in former state.
(6) Since vane does not work at emergency operation, position the vane manually and slowly.
