O Read the safety precautions carefully before operating the unit.
O The contents of this section are vital to ensure safety. Please pay special attention to the following sign.
!
WARNING ........ Incorrect methods of installation may cause death or serious injury.
!
CAUTION ......... Improper installation may result in serious consequence.
Be sure that the unit operates in proper condition after installation. Explain to customer the proper way of operating the unit as
described in the user's guide.
!
O Please request your sales agent or qualiÀ ed technician ti install your unit. Water leakage, sort circuit or À re may occur if you do the
installtion work yourself.
Please observe the instructions stated in the installation manual during the process of installation. Improper installation may cause
O
water leakage, electric shock and À re.
O Make sure that the units are mounted at locations which are able to provide full support to the weight of the units. If not, the units
may collapse and impose danger.
O Observe the rules and regulations of the electrical installtion and the methods described in the installation manual when dealing
with the electrical work. Use power cables approved by the authorities of your country.
O Be sure to use speciÀ ed wire for the connection indoor and outdoor units. Please ensure that the connections are tight after the
conductors of the wire are inserted into the terminals. Improper insertion and loose contact may cause over-heating and À re.
Please use the speciÀ ed components for installtion work. Otherwise, the units may collapse or water leakege, electric shock and
O
À re may occur.
O Be sure to use the speciÀ ed piping set for R-22. Otherwise, this may result in broken copper pipes or faults.
O When installing or removing an air conditioner, only speciÀ ed refrigerant (R-22) shall be allowed, do not allow air or moisture to
remain in the refrigeration cycle. Otherwise, pressure in the refrigeration cycle may become abnormally high so that a rupture may
be caused.
Be sure to ventilate fully if a refrigerant gas leak while at work. If the refrigerant gas comes into contact with À re, a poisonous gas
O
may occur.
O After completion of installation work, check to make sure that there is no refrigeration gas leakage. If the refrigerant gas leaks into
the room, coming into contact with À re in the fan-driven heater, space heater, etc., a poisonuos gas may occur.
O Unauthorized modiÀ cations to the air conditioner may be dangerous. If a breakdown occurs please call a qualiÀ ed air conditoner
technician or electrician. Improper repairs may result in water leakage, electric shock and À re, etc.
!
O A circuit breaker or fuse (20A time delay) must be installed. Without a circuit breaker or fuse the danger of electric shock exists.
A main switch with a contact gap of more than 3.5mm has to be installed in the power supply line to the outdoor unit.
Piping shall be suitable supported with a maximum spacing of 1m between the supports.
O
O Do not install the unit near a location where there is Á ammable gas. The outdoor unit may catch À re if
Á ammable gas leaks around it.
For installation of front panel RAI-ZCPM, please follow exactly the instruction in the manual.
O
O Please ensure smooth Á ow of water when installing the drain hose.

Adjusting the Space between Indoor Unit and False Ceiling Opening
Check the level of the drain pan using a water level to avoid incorrect opera-
O
tion of the drain discharge mechanism in the indoor unit. The drain piping
side of the indoor unit must be approximately 5mm lower than the other part.
Tighten the nuts of the suspension brackets after the adjustment is completed.
O
Apply LOCK-TIGHT paint* to the bolts and nuts in order to prevent them
from loosening. If not done, abnormal noises or sounds may occur and the
indoor unit may fall down.
LOCK-TIGHT paint*: Paint the lock bolts and nuts. Adjust the indoor unit to the
correct position while checking with the checking scales (factory-supplied).
(1) Pattern Board for installation is printed on the packing.
Cut off the checking scale for dimension of opening from packing.
