r When installing or relocating the system, keep the
refrigerant circuit free from substances other than the
URGEKƂGFTGHTKIGTCPV4#UWEJCUCKT#P[RTGU -
ence of air or other foreign substance in the refriger-
ant circuit can cause an abnormal pressure rise or
rupture, resulting in injury.
r Do not change the setting of the protection devices. If

r Do not allow children to play on or around the unit to
prevent injury.
r
Do not touch the refrigerant pipes during and imme-
diately after operation as the refrigerant pipes may be
hot or cold, depending on the condition of the refriger-

sor, and other refrigerant cycle parts. Your hands may
suffer burns or frostbite if you touch the refrigerant
pipes. To avoid injury, give the pipes time to return
to normal temperature or, if you must touch them, be
sure to wear proper gloves.

r
Install drain piping to proper drainage. Improper drain
piping may result in water leakage and property dam-
age.
r Insulate piping to prevent condensation.
r
Be careful when transporting the product.
r Do not turn off the power supply immediately after
stopping operation. Always wait for at least 5 minutes
before turning off the power supply. Otherwise, water
leakage may occur.
r Do not use a charging cylinder. Using a charging cylin-
der may cause the refrigerant to deteriorate.

is not possible when connected to other units.
r Indoor units are for indoor installation only. Outdoor
units can be installed either outdoors or indoors.
r Do not install the air conditioner or heat pump in the
following locations:
(a) Where a mineral oil mist or oil spray or vapor is
produced, for example, in a kitchen.
Plastic parts may deteriorate and fall off or result in
water leakage.
(b) Where corrosive gas, such as sulfurous acid gas,
is produced.
Corroding copper pipes or soldered parts may
result in refrigerant leakage.
(c) Near machinery emitting electromagnetic waves.
Electromagnetic waves may disturb the operation
of the control system and cause the unit to mal-
function.
