Assembly/Cabling
Before troubleshooting or repair work, check the earth wire is connected to the earth
terminals of the main unit, otherwise an electric shock is caused when a leak occurs.
If the earth wire is not correctly connected, contact an electric engineer for rework.
Do not modify the products.
Do not also disassemble or modify the parts. It may cause a fire, electric shock or injury.
For spare parts, use those specified (
∗∗
∗∗
∗).
If unspecified parts are used, a fire or electric shock may be caused.
∗: For details, refer to the parts list.
Before troubleshooting or repair work, do not bring a third party (a child, etc.) except
the repair engineers close to the equipment.
It causes an injury with tools or disassembled parts.
Please inform the users so that the third party (a child, etc.) does not approach the equipment.
Connect the cut-off lead wires with crimp contact, etc, put the closed end side
upward and then apply a water-cut method, otherwise a leak or production of fire is
caused at the users’ side.
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.
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.
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.
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 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.
If incorrect assembly or incorrect wire connection was done, a disaster such as a leak or
fire is caused at user’s side.
WARNING
– 6 –
After the work has finished, be sure to use an insulation tester set (500V Megger) to
check the resistance is 2MΩ or more between the charge section and the non-charge
metal section (Earth position).
If the resistance value is low, a disaster such as a leak or electric shock is caused at user’s side.
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.
When checking the circuit inevitably under condition of the power-ON, use rubber
gloves and others not to touch to the charging section.
If touching to the charging section, an electric shock may be caused.
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.
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.
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.
After repair work (installation of front panel and cabinet) has finished, execute a test
run to check there is no generation of smoke or abnormal sound.
If check is not executed, a fire or an electric shock is caused.
Before test run, install the front panel and cabinet.
Check the following items after reinstallation.
1) The earth wire is correctly connected.
2) The power cord is not caught in the product.
3) There is no inclination or unsteadiness and the installation is stable.
If check is not executed, a fire, an electric shock or an injury is caused.

WARNING
Put on gloves
Cooling check
Be sure to put on the gloves (∗) and a long sleeved shirt:
otherwise an injury may be caused with the parts, etc.
(∗) Heavy gloves such as work gloves
When the power was turned on, start to work after the equipment has been
sufficiently cooled.
As temperature of the compressor pipes and others became high due to cooling/heating
operation, a burn may be caused.

• 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.
Tools exclusive for R410A (The following tools for R410A are required.)
Tools whose specifications are changed for R410A and their interchangeability
(Note) When flaring is carried out for R410A using the conventional flare tools, adjustment of projection
margin is necessary. For this adjustment, a copper pipe gauge, etc. are necessary.
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.
2) Torque wrench 8) Spanner or Monkey wrench
3) Pipe cutter 9) Hole core drill
4) Reamer 10) Hexagon wrench (Opposite side 4mm)
5) Pipe bender 11) Tape measure
