SELECTING THE MOUNTING POSITION
Decide the mounting position with the customer as follows:
CAUTION
Install heat insulation around both the gas and liquid pipes. Failure to do so may cause water leaks.
Use heat insulation with heat resistance above 248 °F. (Reverse cycle model only)
In addition, if the humidity level at the installation location of the refrigerant piping is expected to exceed 70%, install heat
insulation around the refrigerant piping. If the expected humidity level is 70-80%, use heat insulation that is 15 mm (19/32 in.) or
thicker and if the expected humidity exceeds 80%, use heat insulation that is 20 mm (3/4 in.) or thicker.
If heat insulation is used that is not as thick as specified, condensation may form on the surface of the insulation.
In addition, use heat insulation with heat conductivity of 0.045 W/(m·K) or less (at 68 °F).
••
••
• Use pipe with water-resistant heat insulation.
INDOOR UNIT
(1) Install the indoor unit level on a strong wall which is not subject to vibration.
(2) The inlet and outlet ports should not be obstructed : the air should be able to

SPECIAL PRECAUTIONS
When Wiring
ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR
DEATH. ONLY A QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD
ATTEMPT TO WIRE THIS SYSTEM.
•
Do not supply power to the unit until all wiring and tubing are completed
or reconnected and checked.
•
Highly dangerous electrical voltages are used in this system. Carefully
refer to the wiring diagram and these instructions when wiring. Improper
connections and inadequate grounding can cause accidental injury or
death.
•
Ground the unit following local electrical codes.
•
Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard.
WARNING:
CAUTION:
When Transporting
Be careful when picking up and moving the indoor and outdoor units. Get
a partner to help, and bend your knees when lifting to reduce strain on
your back. Sharp edges or thin aluminum fins on the air conditioner can
cut your fingers.
When Installing...
...In a Ceiling or Wall
Make sure the ceiling/wall is strong enough to hold the unit’s weight. It
may be necessary to construct a strong wood or metal frame to provide
added support.
...In a Room
Properly insulate any tubing run inside a room to prevent “sweating” that
can cause dripping and water damage to walls and floors.
...In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to provide a solid, level
foundation for the outdoor unit. This prevents water damage and abnormal vibration.
...In an Area with High Winds
Securely anchor the outdoor unit down with bolts and a metal frame.
Provide a suitable air baffle.
...In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that is higher than drifting
snow. Provide snow vents.
When Connecting Refrigerant Tubing
•
Keep all tubing runs as short as possible.
•
Use the flare method for connecting tubing.
•
Apply refrigerant lubricant to the matching surfaces of the flare and
union tubes before connecting them, then tighten the nut with a torque
wrench for a leak-free connection.
•
Check carefully for leaks before starting the test run.
NOTE:
Depending on the system type, liquid and gas lines may be either narrow
or wide. Therefore, to avoid confusion the refrigerant tubing for your
particular model is specified as either “small” or “large” rather than as
“liquid” or “gas”.
When Servicing
•
Turn the power OFF at the main circuit breaker panel before opening
the unit to check or repair electrical parts and wiring.
•
Keep your fingers and clothing away from any moving parts.
•
Clean up the site after you finish, remembering to check that no metal
scraps or bits of wiring have been left inside the unit being serviced.
•
After installation, explain correct operation to the customer, using the
operating manual.

This air conditioner uses new refrigerant HFC (R410A).
The basic installation work procedures are the same as conventional refrigerant models.
However, pay careful attention to the following points:
1 Since the working pressure is 1.6 times higher than that of conventional refrigerant models, some of the piping and
installation and service tools are special. (See the table below.)
Especially, when replacing a conventional refrigerant model with a new refrigerant R410A model, always replace the
conventional piping and flare nuts with the R410A piping and flare nuts.
2 Models that use refrigerant R410A have a different charging port thread diameter to prevent erroneous charging with
conventional refrigerant and for safety. Therefore, check beforehand. [The charging port thread diameter for R410A is
1/2 UNF 20 threads per inch.]
3 Be more careful that foreign matter (oil, water, etc.) does not enter the piping than with refrigerant models. Also, when
storing the piping, securely seal the openings by pinching, taping, etc.
4 When charging the refrigerant, take into account the slight change in the composition of the gas and liquid phases, and
always charge from the liquid phase side whose composition is stable.
5 When moving, if the compressor stops during pump down, close the valve immediately.
Special tools for R410A
Copper pipes
Contents of change
Pressure is high and cannot be measured with a conventional gauge. To prevent erroneous mixing of other
refrigerants, the diameter of each port has been changed.
It is recommended the gauge with seals –0.1 to 5.3 MPa (–76 cmHg to 53 kgf/cm
2
) for high pressure. –0.1 to
3.8 MPa (–76 cmHg to 38 kgf/cm
2
) for low pressure.
To increase pressure resistance, the hose material and base size were changed.
A conventional vacuum pump can be used by installing a vacuum pump adapter.

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 valve or capillary tube may become blocked with contaminants.
As an air conditioner using R410A incurs pressure higher than when using
conventional refrigerant, it is necessary to choose adequate materials.
Thicknesses of copper pipes used with R410A are as shown in the table. Never
use copper pipes thinner than that in the table even when it is available on
the market.
