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.
WARNING
O
Please request your sales agent or quali ed technician ti install your unit. Water leakage, sort circuit or re may occur if you do the
installtion work yourself.
O
Please observe the instructions stated in the installation manual during the process of installation. Improper installation may cause
water leakage, electric shock and 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 speci 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 re.
O
Please use the speci ed components for installtion work. Otherwise, the units may collapse or water leakege, electric shock and
re may occur.
O
Be sure to use the speci 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 speci 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.
O
Be sure to ventilate fully if a refrigerant gas leak while at work. If the refrigerant gas comes into contact with re, a poisonous gas
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 re in the fan-driven heater, space heater, etc., a poisonuos gas may occur.
O
Unauthorized modi cations to the air conditioner may be dangerous. If a breakdown occurs please call a quali ed air conditoner
technician or electrician. Improper repairs may result in water leakage, electric shock and 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.
O
Piping shall be suitable supported with a maximum spacing of 1m between the supports.
O
Do not install the unit near a location where there is ammable gas. The outdoor unit may catch re if
ammable gas leaks around it.
O
For installation of front panel RAI-ZCPM, please follow exactly the instruction in the manual.
O
Please ensure smooth ow of water when installing the drain hose.

CAUTION
The installtion
height of indoor
unit must be 2.3m
or more.
In case the pipe lenght is more than 5m, add refrigerant
R22 at 35 gram per every meter exceeds. However,
pipe lenght shall not exceed 50m.
Be sure to
completely
seal any
gap with
putty.
The indoor piping should be
insulated with the enclosed
insulation pipe. (If the
insulator is insuf cient, please
use commercial products).
O
The difference in
height between the
indoor and outdoor
unit should be kept
below 30m.
O
The connecting
pipe, no matter big
or small, should
all be insulated
with insulation pipe
and then wrapped
with vinyl tape.
(The insulator will

CAUTION
O
Check the level of the drain pan using a water level to avoid incorrect opera-
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.
O
Tighten the nuts of the suspension brackets after the adjustment is completed.
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
