2SAFETY PRECAUTION
Cautions for units utilizing refrigerant R410A
2-1. CAUTIONS RELATED TO NEW REFRIGERANT
Use new refrigerant pipes.
Make sure that the inside and outside of refrige-
rant 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.
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.)
Use ester oil, ether oil or alkylbenzene oil (small
amount) as the refrigerant oil applied to flares
and flange connections.
In case of using the existing pipes for R22, be careful with
the followings.
· For RP100, 125 and 140, 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.
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.
Do not use refrigerant other than R410A.
If other refrigerant (R22 etc.) is used, chlorine in refrige-
rant 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.
Keep the tools with care.
If dirt, dust or moisture enter into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of com-
pressor.
Do not use a charging cylinder.
If a charging cylinder is used, the composition of refrigera-
nt will change and the efficiency will be lowered.

Tools for R410A
Contamination inside refrigerant piping can cause deterio-
ration of refrigerant oil etc.
If dirt, dust or moisture enter into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of com-
pressor.
If large amount of mineral oil enter, that can cause deterio-
ration of refrigerant oil etc.
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
(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.)

[4] Refrigerant leakage detection function
This air conditioner (outdoor unit PUHZ-RP•HA2) can detect refrigerant leakage which may happen during a long period of
use. In order to enable the leakage detection, settings are required to let the unit memorize the initial conditions(initial
learning). Refer to 13-3 INITIAL SETTINGS FOR REFRIGERANT LEAKAGE DETECTION FUNCTION.

2-2. PRECAUTIONS WHEN REUSING EXISTING R22 REFRIGERANT PIPES
(1) Flowchart
Connecting a new air conditioner
1Flaring work should be done so that flare meets the dimension for R410A.
Use flare nut provided with indoor and outdoor unit.
2When using gas piping of [19.05mm for RP100, 125 or 140.
Make sure that DIP SW8-1 on outdoor unit controller board is set to ON.
WThis is to keep the pressure on pipes within permissible range.
●Use different diameter joint or adjust the piping size by brazing.
3When using pipes larger than specified size for RP35, 50, 60 or 71.
Make sure that DIP SW8-1 on outdoor unit controller board is set to ON.
W This is to prevent oil flow ratio from lowering due to the decrease in flowing refrigerant.
●Use different diameter joint or adjust the piping size by brazing.
4When existing pipes are specified size.
The pipes can be reused referring to TECHNICALDATA BOOK (OCS05).
●Use different diameter joint or adjust the piping size by brazing.
★When using existing pipes for RP100, 125 and 140.
Make sure that DIP SW8-2 on outdoor unit controller board is set to ON and perform
replacement operation.
wChemical compounds containing chlorine left in existing pipes are collected by replace filter.
●The air conditioner automatically performs cooling operation through replace filter for about 2 hours.
Measure the existing pipe thickness and check for damage.
Check if existing air conditioner can operate.
Existing air conditioner can
operate.
Disconnect existing air con-
ditioner from piping.
Existing pipes can be reused.
In case the unit is RP35, 50,
60 or 71 which utilizes AB oil.
In case the unit is RP100, 125
or 140 which utilize ester oil.
Perform cooling operation
for about 30 minutes and
then do a pump down work.
Use a refrigerant recovery
equipment to collect the re-
frigerant.
Existing air conditioner
cannot operate.
The existing pipe thickness meets speci-
fications and the pipes are not damaged.
The existing pipe thickness does not meet
specifications or the pipes are damaged.
Connect a new air conditioner. Connect a new air conditioner.
Perform replacement operation.
·When performing replacement operation, make sure that DIP SW8-2 on outdoor unit controller board is
set to ON.
wChemical compounds containing chlorine left in existing pipes are collected by replace filter.
●The air conditioner automatically performs cooling operation through replace filter for about 2 hours.
Existing pipes cannot be
reused. Use new pipes.
wIn case existing pipes were used
for gas or oil heat pump system,
be sure to clean the pipes for RP100-140 models.
Use new pipes for RP35-71 models.

(2) Cautions for refrigerant piping work
New refrigerant R410A is adopted for replacement inverter series. Although the refrigerant piping work for R410A is same
as for R22, exclusive tools are necessary so as not to mix with different kind of refrigerant. Furthermore as the working
pressure of R410A is 1.6 time higher than that of R22, their sizes of flared sections and flare nuts are different.
1Thickness of pipes
Because the working pressure of R410A is higher compared to R22, be sure to use refrigerant piping with thickness
shown below. (Never use pipes of 0.7mm or below.)
2Dimensions of flare cutting and flare nut
The component molecules in HFC refrigerant are smaller compared to conventional refrigerants. In addition to that,
R410A is a refrigerant, which has higher risk of leakage because of its working pressure higher than that of other refriger-
ants. Therefore, to enhance airtightness and intensity, flare cutting dimension of copper pipe for R410A have been speci-
fied separately from the dimensions for other refrigerants as shown below. The dimension B of flare nut for R410A also
have partly been changed to increase intensity as shown below. Set copper pipe correctly referring to copper pipe flaring
dimensions for R410A below. For 1/2” and 5/8”, the dimension B changes.
Use torque wrench corresponding to each dimension.

CHARGELESS SYSTEM
PRE-CHARGED REFRIGERANT IS SUPPLIED FOR PIPING LENGTH AT SHIPMENT.
Max.30m(PUHZ-RP35/50/60/71/100/125/140)
The refrigerant circuit with LEV(Linear Expansion Valve) and power receiver always control the optimal refrigerant
level regardless of the length (30m max. and 5m min.) of piping. The additional refrigerant charging work during
installation often causes problems. Heretofore it is completely eliminated. This unique system improves the quality
and reliability of the work done. It also helps to speed up the installation time.

Piping and wiring connection can
be made from the rear direction only.
3. ATTACHING THE CONDUIT
In order to attach the conduit, it is
necessary to fix the metal plate with
2 screws to the back panel. Procure
the metal plate and make screw holes
locally. It is recommended to use the
metal plate shown below. Align the
metal plate to the marks on the unit
and attach it.
<Foundation bolt height>
Please secure the unit firmly
with 4 foundation (M10) bolts.
