2 English
• Install the air conditioner, power supply wiring, remote
controller wiring and transmission wiring at least 1
meter away from televisions or radios to prevent image
interference or noise.
(Depending on the radio waves, a distance of 1 meter may
not be sufficient to eliminate the noise.)
• Do not install the air conditioner in places such as the
following:
1. Where there is mist of oil, oil spray or vapour for
example a kitchen.
Resin parts may deteriorate, and cause them to fall out
or water to leak.
2. Where corrosive gas, such as sulfurous acid gas, is
produced.
Corrosion of copper pipings or brazed parts may cause
the refrigerant to leak.
3. Where there is machinery which emits electromagnetic
waves.
Electromagnetic waves may disturb the control system,
and cause malfunction of the equipment.
4. Where flammable gases may leak, where carbon fibre
or ignitable dust is suspended in the air or where volatile
flammables, such as thinner or gasoline, are handled.
If the gas should leak and remained around the air
conditioner, it may cause ignition.
2. BEFORE INSTALLATION
• Make sure to use the R410A refrigerant before the
installation work.
(Otherwise, the unit can not operate normally.)
• For installation of outdoor unit, refer to the installation
manual attached to the outdoor unit.
• Do not throw away the accessories required for installation
until the installation is finished.
2-1 PRECAUTION
• Be sure to instruct the customer how to properly operate
the system (particularly the cleaning of air filter, operation
method, temperature adjusting method) showing the
attached operation manual to the person.
• Do not install the unit where the atmosphere is salty
such as near the seaside, where the voltage frequently
fluctuates or in a vehicle or a boat.
