measures
When performing repairs using a gas burner, replace the refrigerant with nitrogen gas because
the oil that coats the pipes may otherwise burn.
When repairing the refrigerating cycle, take the following measures.
1)
Be attentive to fire around the cycle.
When using a gas stove, etc, be sure to put out fire before work; otherwise the oil mixed with
refrigerant gas may catch fire.
No fire
2)
Do not use a welder in the closed room.
When using it without ventilation, carbon monoxide poisoning may be caused.
3)
Do not bring inflammables close to the refrigerant cycle, otherwise fire of the welder may catch
the inflammables.
The refrigerant used by this air conditioner is the R410A.
Check the used refrigerant name and use tools and materials of the parts which match with it.
For the products which use R410A refrigerant, the refrigerant name is indicated at a position on
the outdoor unit where is easy to see.
To prevent miss-charging, the route of the service port is changed from one of the former R22.
Do not use any refrigerant different from the one specified for complement or replacement.
Otherwise, abnormally high pressure may be generated in the refrigeration cycle, which may
result in a failure or explosion of the product or an injury to your body.
For an air conditioner which uses R410A, never use other refrigerant than R410A.
For an air conditioner which uses other refrigerant (R22, etc.), never use R410A.
If different types of refrigerant are mixed, abnormal high pressure generates in the refrigerating
cycle and an injury due to breakage may be caused.
Do not charge refrigerant additionally.
If charging refrigerant additionally when refrigerant gas leaks, the refrigerant composition in the
refrigerating cycle changes resulted in change of air conditioner characteristics or refrigerant over
Refrigerant
the specified standard amount is charged and an abnormal high pressure is applied to the inside
of the refrigerating cycle resulted in cause of breakage or injury.
Therefore if the refrigerant gas leaks, recover the refrigerant in the air conditioner, execute
vacuuming, and then newly recharge the specified amount of liquid refrigerant.
In this time, never charge the refrigerant over the specified amount.
When recharging the refrigerant in the refrigerating cycle, do not mix the refrigerant or air other
than R410A into the specified refrigerant.
If air or others is mixed with the refrigerant, abnormal high pressure generates in the refrigerating
cycle resulted in cause of injury due to breakage.
After installation work, check the refrigerant gas does not leak.
If the refrigerant gas leaks in the room, poisonous gas generates when gas touches to fire such
as fan heater, stove or cocking stove though the refrigerant gas itself is innocuous.
Never recover the refrigerant into the outdoor unit.
When the equipment is moved or repaired, be sure to recover the refrigerant with recovering device.
The refrigerant cannot be recovered in the outdoor unit; otherwise a serious accident such as
breakage or injury is caused.
After repair work, surely assemble the disassembled parts, and connect and lead the removed
wires as before.
Perform the work so that the cabinet or panel does not catch the inner wires.

When the refrigerant gas leaks during work, execute ventilation.
If the refrigerant gas touches to a fire, poisonous gas generates.
A case of leakage of the refrigerant and the closed room full with gas is dangerous because a
shortage of oxygen occurs. Be sure to execute ventilation.
If refrigerant gas has leaked during the installation work, ventilate the room immediately.
Ventilation
If the leaked refrigerant gas comes in contact with fire, noxious gas may generate.
After installation work, check the refrigerant gas does not leak. If the refrigerant gas leaks in the
room, poisonous gas generates when gas touches to fire such as fan heater, stove or cocking
stove though the refrigerant gas itself is innocuous.

When the refrigerant gas leaks, find up the leaked position and repair it surely.
If the leaked position cannot be found up and the repair work is interrupted, pump-down and
tighten the service valve, otherwise the refrigerant gas may leak into the room.
The poisonous gas generates when gas touches to fire such as fan heater, stove or cocking stove
though the refrigerant gas itself is innocuous.
When installing equipment which includes a large amount of charged refrigerant such as a multi
air conditioner in a sub-room, it is necessary that the density does not the limit even if the
refrigerant leaks.
If the refrigerant leaks and exceeds the limit density, an accident of shortage of oxygen is caused.
Tighten the flare nut with a torque wrench in the specified manner.
Excessive tighten of the flare nut may cause a crack in the flare nut after a long period, which may

result in refrigerant leakage.
Nitrogen gas must be used for the airtight test.
The charge hose must be connected in such a way that it is not slack.
For the installation/moving/reinstallation work, follow to the Installation Manual.
If an incorrect installation is done, a trouble of the refrigerating cycle, water leak, electric shock or
fire is caused.
Once the repair work has been completed, check for refrigerant leaks, and check the insulation
resistance and water drainage.
Then perform a trial run to check that the air conditioner is running properly.
After repair work has finished, check there is no trouble. If check is not executed, a fire, electric
shock or injury may be caused. For a check, turn off the power breaker.

New Refrigerant (R410A)
This air conditioner adopts a new HFC type refrigerant (R410A) which does not deplete the ozone layer.
1. Safety Caution Concerned to New Refrigerant
The pressure of R410A is high 1.6 times of that of the former refrigerant (R22).
Accompanied with change of refrigerant, the refrigerating oil has been also changed.
Therefore, be sure that water, dust, the former refrigerant or the former refrigerating oil is not mixed into the
refrigerating cycle of the air conditioner with new refrigerant during installation work or service work.
If an incorrect work or incorrect service is performed, there is a possibility to cause a serious accident.
Use the tools and materials exclusive to R410A to purpose a safe work.
2. Cautions on Installation/Service
1) Do not mix the other refrigerant or refrigerating oil.
For the tools exclusive to R410A, shapes of all the joints including the service port differ from those of
the former refrigerant in order to prevent mixture of them.
2) As the use pressure of the new refrigerant is high, use material thickness of the pipe and tools which are
specified for R410A.
3) In the installation time, use clean pipe materials and work with great attention so that water and others do
not mix in because pipes are affected by impurities such as water, oxide scales, oil, etc.
Use the clean pipes.
Be sure to brazing with flowing nitrogen gas. (Never use gas other than nitrogen gas.)
4) For the earth protection, use a vacuum pump for air purge.
5) R410A refrigerant is azeotropic mixture type refrigerant.
Therefore use liquid type to charge the refrigerant. (If using gas for charging, composition of the
refrigerant changes and then characteristics of the air conditioner change.)
3. Pipe Materials
For the refrigerant pipes, copper pipe and joints are mainly used.
It is necessary to select the most appropriate pipes to conform to the standard.
Use clean material in which impurities adhere inside of pipe or joint to a minimum.
1) Copper pipe
<Piping>
The pipe thickness, flare finishing size, flare nut and others differ according to a refrigerant type.
When using a long copper pipe for R410A, it is recommended to select “Copper or copper-base pipe
without seam” and one with bonded oil amount 40mg/10m or less.
Also do not use crushed, deformed, discolored (especially inside) pipes.
(Impurities cause clogging of expansion valves and capillary tubes.)
<Flare nut>
Use the flare nuts which are attached to the air conditioner unit.
2) Joint
The flare joint and socket joint are used for joints of the copper pipe.
The joints are rarely used for installation of the air conditioner. However clear impurities when using them.

4. Tools
1. Required Tools for R410A
Mixing of different types of oil may cause a trouble such as generation of sludge, clogging of capillary,
etc. Accordingly, the tools to be used are classified into the following three types.
1) Tools exclusive for R410A (Those which cannot be used for conventional refrigerant (R22))
2) Tools exclusive for R410A, but can be also used for conventional refrigerant (R22)
3) Tools commonly used for R410A and for conventional refrigerant (R22)
The table below shows the tools exclusive for R410A and their interchangeability.

General tools (Conventional tools can be used.)
In addition to the above exclusive tools, the following equipments which serve also for R22 are necessary
as the general tools.
1) Vacuum pump. Use vacuum pump by
attaching vacuum pump adapter.
7) Screwdriver (+, -)
2) Torque wrench
8) Spanner or Monkey wrench
3) Pipe cutter
9) Hole core drill

7. REPLACEMENT OF SERVICE P.C. BOARD
7-1. Indoort Unit
CAUTION
<Model name: RAV-SM∗∗∗CTP∗>
For the above models, set the CODE No. “
” and the setting data “0000” (initial) to “0001”.
<Note: when replacing the P.C. board for indoor unit servicing>
The nonvolatile memory (hereafter called EEPROM, IC503) on the indoor unit P.C. board before replacement
includes the model specific type information and capacity codes as the factory-set value and the important
setting data which have been automatically or manually set when the indoor unit is installed, such as system/
indoor/group addresses, high ceiling select setting, etc.
When replacing the P.C. board for indoor unit servicing, follow the procedures below.
After replacement completes, confirm whether the settings are correct by checking the indoor unit No., Group
header unit/follower unit settings and perform the cooling cycle confirmation through the trial operation.
<Replacement procedures>
CASE 1
Before replacement, the indoor unit can be turned on and the setting data can be read out by
wired remote control operation.
EEPROM data read out [1]
Replacement of P.C. board for Indoor unit servicing and power on [2]
Writing the read out EEPROM data [3]
Power reset
(for all indoor units connected to the remote control when the group operation control is performed.)
CASE 2
The EEPROM before replacement is defective and the setting data cannot be read out.
EEPROM data read out [2]
Writing the setting data to EEPROM, such as high ceiling installation setting and
optional connection setting, etc., based on the customer information. [3]
Power reset
(for all indoor units connected to the remote control when the group operation control is performed.)
