Installation
Choosing the installation location
Installation location requirements
• There must be no obstacles near the air inlet and
outlet.
• Install the indoor unit on a ceiling that can support its
weight.
• Maintain sufficient clearance around the indoor unit.
• Before installing the indoor unit, be sure to check
whether the chosen location is well-drained.
• The indoor unit must be installed such that it is beyond
public access and is not touchable by users.
• A vibration-resistant location that is not inclined (If the
indoor unit is installed on a structure that is not sturdy,
it may fall and get damaged or cause injury.)
• Where it is not exposed to direct sunshine.
• Where the air filter can be removed and cleaned easily.
CAUTION
• As a rule, the unit cannot be installed at a height of
less that 8.2ft (2.5m).
• If you install a cassette type indoor unit on the ceiling
when temperature is over 80.6°F (27°C) and humidity
is over 80%, you must apply an extra 0.39inch (10mm)
thick polyethylene insulation or a similar type of
insulation to the body of the indoor unit.
Do not install the air conditioner in following places.
•
•
A place with exposure to mineral oil, oil vapour or
cooking area where there is spray (If oil adheres to the
heat exchanger, performance degradation, spray or
condensation scattering may occur. If oil adheres to a
plastic component, the component may deform or get
damaged. Such issues may result in a system failure or
refrigerant leak.)
The place where corrosive gas such as sulphuric acid
gas generates from the vent pipe or air outlet.
• The copper pipe or connection pipe may corrode and
refrigerant may leak.
• The place where there is a machine that generates
electromagnetic waves. The air conditioner may not
operate normally due to control system.
• The place where there is a danger of existing
combustible gas, carbon fibre or flammable dust.
• The place where thinner or gasoline is handled. Gas
may leak and it may cause fire.
