Selecting Installation Site
When the conditions in the ceiling are exceeding
86°F and a relative humidity of 80%, or when
fresh air is inducted into the ceiling, an additional
insulation is required (minimum 0.4in / thickness,
polyethylene foam).
1. Select an installation site where the following
conditions are fullled and that meets your
customer's approval.
• Where optimum air distribution can be ensured.
• Where nothing blocks air passage.
• Where condensate water can be properly
drained.
• Where the ceiling is level, not noticeably on an
incline.
• Where sucient clearance for maintenance and
service can be ensured.
• Where there is no risk of ammable gas leaking.
• The equipment is not intended for use in a
potentially explosive atmosphere.
• Where piping between indoor and outdoor units
does not exceed the allowable limit. (Refer to
the installation manual of the outdoor unit.)
• Keep indoor unit, outdoor unit, inter unit wiring
and remote control wiring at least 3 feet away
from televisions and radios. This is to prevent
image interference and noise in those electrical
appliances. (Noise may be generated depending
on the conditions under which the electric wave
is generated, even if proper distance is kept.)
• When installing the wireless remote control kit,
the distance between wireless remote control
and indoor unit might be shorter if there are
uorescent lights that are electrically started in
the room. The indoor unit must be installed as
far away as possible from uorescent lights.
2. Ceiling height
Install this unit where the height of bottom panel is
more than 8' so that the user cannot easily touch.

the casing outlet, implement the refrigerant
and drain piping and wiring for remote
control (unnecessary for wireless type). Refer
to each piping or wiring section.
• After making an opening in the ceiling, it may
be necessary to reinforce ceiling beams to
keep the ceiling level and to prevent it from
vibrating. Consult the builder for details.
3. Install the threaded rod. (Use either a M8 or
M10 size rod.)
• Use expansible hooks, sunken anchors or
other eld supplied parts to reinforce the
ceiling in order to bear the weight of the unit.
• Adjust clearance from the ceiling before
proceeding further. See Fig. 4.4 for
Installation example.

CAUTION
• DO NOT mix anything other than the specied refrigerant, such as air, etc., inside the refrigerant
circuit.
• Execute heat insulation work completely on both sides of the gas piping and liquid piping.
Otherwise, this can sometimes result in water leakage. (When using a heat pump, the
temperature of the gas piping can reach up to approximately 248° F. Use insulation which is
suciently resistant.)
• Also, in cases where the temperature and humidity of the refrigerant piping sections might
exceed 86° F or Rh80%, reinforce the refrigerant insulation (3/4" or thicker). Condensation may
form on the surface of the insulating material.
• Before rigging tubes, check which type of refrigerant is used.
• Use a pipe cutter and are suitable for used refrigerant.
• Only use annealed material for are connections.
• If the refrigerant gas leaks during the work, ventilate the area. A toxic gas is emitted by the
refrigerant gas being exposed to a re.
• Make sure there is no refrigerant gas leak. A toxic gas may be released by the refrigerant gas
leaking indoor and being exposed to ames from an area heater, cooking stove, etc.
• Refer to the Fig 5.1 for the dimensions of are nuts spaces and the appropriate tightening
torque. (Over-tightening may damage the are and cause leaks.)
• Check whether the height drop between the indoor unit and outdoor unit, and the length of
refrigerant pipe meet the following requirements in Fig 5.2:
