2.2. Special tools for R410A
Tool name
Change from R22 to R410A
Gauge manifold
Pressure is high and cannot be measured with a R22
gauge. To prevent erroneous mixing of other refrigerants,
the diameter of each port has been changed.
It is recommended to use gauge with seals -0.1 to 5.3 MPa
(-1 to 53 bar) for high pressure.
-0.1 to 3.8 MPa (-1 to 38 bar) for low pressure.
Charge hose
To increase pressure resistance, the hose material and base
size were changed. (R410A)
Vacuum pump
A conventional vacuum pump can be used by installing a
vacuum pump adapter.
(Use of a vacuum pump with a series motor is prohibited.)
Gas leakage detector
Special gas leakage detector for HFC refrigerant R410A.
Copper pipes
It is necessary to use seamless copper pipes and it is desirable that the amount of residual
oil is less than 40 mg/10 m. Do not use copper pipes having a collapsed, deformed or
discolored portion (especially on the interior surface). Otherwise, the expansion value or
capillary tube may become blocked with contaminants.
As an air conditioner using R410A incurs pressure higher than when using R22, it is neces
-
sary to choose adequate materials.
WARNING
• Do not use the existing (for R22) piping and flare nuts.
If the existing materials are used, the pressure inside the refrigerant cycle will rise and
cause failure, injury, etc. (Use the special R410A materials.)
• Use (refill or replace with) specified refrigerant (R410A) only. Use of unspecified refrig
-
erant can cause product malfunction, burst, or injury.
• Do not mix any gas or impurities except specified refrigerant (R410A). Inflow of air or
application of unspecified material makes the internal pressure of the refrigerant cycle
too high, and may cause product malfunction, burst of piping, or injury.
WARNING
• For appropriate working of the air conditioner, install it as written in this manual.
• To connect indoor unit and outdoor unit, use air conditioner piping and cables available
through your local distributor. This manual describes proper connections using such
installation set.
• Do not turn on the power until all work has been completed.
CAUTION
This manual describes how to install the indoor unit only. To install the outdoor unit, (if
any), refer to the installation manual included in each product.
• Be careful not to scratch the air conditioner when handling it.
• After installation, explain correct operation to the customer, using the operating manual.

3. GENERAL SPECIFICATION
This INSTALLATION MANUAL briefly outlines where and how to install the air conditioning system.
Please read over the entire set of instructions for the indoor and outdoor units and make sure all
accessory parts listed are with the system before beginning.
3.1. Type of copper pipe and insulation material
CAUTION
Refer to the installation manual of the outdoor unit for description of the length of
connecting pipe or for difference of its elevation.
Gas pipe size (thickness) [mm]
Liquid pipe size (thickness) [mm]
Ø
15.88 (5/8 in.)
Ø
9.52 (3/8 in.)
CAUTION
• Wrap heat insulation around both of the gas pipe and the liquid pipe.
No heat-insulation work or incorrect heat-insulation work may cause water leaks.
• In a reverse cycle model, use heat insulation with heat resistance above 120 °C.
• If expected humidity of the installation location of refrigerant pipes is higher than 70
%, wrap the heat insulation around the refrigerant pipes.
If the expected humidity is between 70 % and 80 %, use heat insulation that has
thickness of 15 mm or more.
If the expected humidity is higher than 80 %, use heat insulation that has thickness
of 20 mm or more.
• Using of thinner heat insulation than specified above may cause a condensation on
the surface of the insulation.
• Use heat insulation with thermal conductivity of 0.045 W/(m•K) or less, at 20 °C.
3.2. Additional materials required for installation
A. Refrigeration (armored) tape
B. Insulated staples or clamps for connecting wire (See your local electrical codes.)
C. Putty
D. Refrigeration lubricant
E. Clamps or saddles to secure refrigerant piping
4. ELECTRICAL REQUIREMENT
The indoor unit is powered from the outdoor unit. Do not power indoor unit from separate
power source.
WARNING
Standard for electrical wiring and equipment differs in each country or region. Before you
start electrical working, confirm related regulations, codes, or standards.
