2SAFETY PRECAUTION
2-2. CAUTIONS RELATED TO NEW REFRIGERANT
Cautions for units utilizing refrigerant R410A
Use new refrigerant pipes.
Make sure that the inside and outside of refrige-
rant piping is clean and it has no contaminants
such as sulfur, oxides, dirt, shaving particles, etc,
which are hazard to refrigerant cycle.
In addition, use pipes with specified thickness.
Store the piping to be used indoors during instal-
lation, and keep both ends of the piping sealed
until just before brazing. (Leave elbow joints, etc.
in their packaging.)
The refrigerant oil applied to flare and flange
connections must be ester oil, ether oil or
alkylbezene oil in a small amount.
In case of using the existing pipes for R22, be careful with
the followings.
· 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.
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.
Handle tools with care.
If dirt, dust or moisture enters 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 enters into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
If large amount of mineral oil enters, 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.
Use the specified refrigerant only.
Never use any refrigerant other than that specified.
Doing so may cause a burst, an explosion, or fire when the
unit is being used, serviced, or disposed of.
Correct refrigerant is specified in the manuals and on the
spec labels provided with our products.
We will not be held responsible for mechanical failure,
system malfunction, unit breakdown or accidents caused
by failure to follow the instructions.
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.
2-1. ALWAYS OBSERVE FOR SAFETY
Before obtaining access to terminal, all supply circuits must be disconnected.
Preparation before the repair service.
• Prepare the proper tools.
• Prepare the proper protectors.
• Provide adequate ventilation.
• After stopping the operation of the air conditioner, turn off the power-supply breaker.
• Discharge the condenser before the work involving the electric parts.
Precautions during the repair service.
• Do not perform the work involving the electric parts with wet hands.
• Do not pour water into the electric parts.
• Do not touch the refrigerant.
• Do not touch the hot or cold areas in the refrigerating cycle.
• When the repair or the inspection of the circuit needs to be done without turning off the power,
exercise great caution not to touch the live parts.

Unit
[3] Service tools
Use the below service tools as exclusive tools for R410A refrigerant.
[4] Refrigerant leakage detection function
This air conditioner 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 14-3. INITIAL SETTINGS FOR REFRIGERANT LEAKAGE DETECTION FUNCTION.
[1] Cautions for service
(1) Perform service after recovering 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.)
No. Tool name Specifications

2-3. PRECAUTIONS WHEN REUSING EXISTING R22 REFRIGERANT PIPES
(1) Flowchart
Connecting a new air conditioner
Flaring work should be done so that flare meets the dimension for R410A.
Use flare nut provided with indoor and outdoor unit.
When using gas piping of :19.05mm for SHW112, 140.
Make sure that DIP SW8-1 on outdoor unit controller board is set to ON.
This is to keep the pressure on pipes within permissible range.
●Use different diameter joint or adjust the piping size by brazing.
When using pipes larger than specified size for SHW80.
Make sure that DIP SW8-1 on outdoor unit controller board is set to ON.

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.
When existing pipes are specified size.
The pipes can be reused.
●Use different diameter joint or adjust the piping size by brazing.
SHW·HA
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.
Perform cooling operation
for about 30 minutes and
then do a pump down work.
Use a refrigerant recovery
equipment to recover the
refrigerant.
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.
●The air conditioner automatically performs cooling operation through replace filter for about 2 hours.
Existing pipes cannot be
reused. Use new pipes.
+In case existing pipes were used
for gas or oil heat pump system,
be sure to clean the pipes.

(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 times 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 0.7 mm 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 its working pressure is higher than that of other refrig-
erants. Therefore, to enhance airtightness and intensity, flare cutting dimension of copper pipe for R410A has been
specified separately from the dimensions for other refrigerants as shown below. The dimension B of flare nut for R410A
also has 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 inch, the dimension B changes.
Use torque wrench corresponding to each dimension.
