FOR THE FOLLOWING ITEMS, TAKE SPECIAL CARE
DURING CONSTRUCTION AND CHECK AFTER
INSTALLATION IS FINISHED.
1. Items to be checked after completion of work
∗
Also review the “SAFETY PRECAUTIONS”
2. Items to be checked at time of delivery
3. Points for explanation about operations
2-4
NOTE TO THE INSTALLER
Be sure to instruct customers how to properly operate the unit
(especially cleaning filters, operating different functions, and
adjusting the temperature) by having them carry out operations
themselves while looking at the manual.
3.
SELECTING INSTALLATION SITE AND
AIR FLOW DIRECTION
3-1
Select an installation site where the following
conditions are fulfilled and that meets your
customer’s approval.
• In the upper space (including the back of the ceiling) of the
indoor unit where there is no possible dripping of water from
the refrigerant piping, drain piping, water pipinge, etc.
• Where optimum air distribution can be ensured.
• Where nothing blocks air passage.
• Where condensate can be properly drained.
• Where the ceiling is strong enough to bear the indoor unit
weight.
• Where the false ceiling is not noticeably on an incline.
• Where sufficient clearance for maintenance and service can
be ensured.
• Where there is no risk of flammable gas leakage.
• Where piping between indoor and outdoor units is possible
within the allowable limit.
(Refer to the installation manual for the outdoor and BEV units.)
[PRECAUTION]
If installing the wireless kit in a room with electronic fluorescent
lighting (inverter or rapid start type), the remote controller’s
transmission distance may be shortened. Indoor units should
be installed as far away from fluorescent lighting as possible.
• Install the indoor and outdoor units, power supply wiring and
connecting wiring at least 1 meter away from televisions or
radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter may
not be sufficient enough to eliminate the noise.)
[CAUTION]
Only use the included parts or parts which match the specifica-
tions when installing the unit.
• Install the indoor unit no less than 2.5m above the floor.
Where unavoidably lower, take what measures are neces-
sary to keep hands out of the air outlet.
∗∗
Space is required to attach/detach corner covers.

Air flow direction
Select the air flow direction that best suits the unit’s location.
2-way and 3-way air flow must be set from the remote control-
ler. For details, see “10. FIELD SETTINGS”.
NOTE
• Restrictions are placed on piping direction, therefore select
flow direction from the below patterns.

Items to be checked
If not properly done, what
is likely to occur
Check
Are the indoor and out-
door unit fixed firmly?
The unit may drop,
vibrate or make noise.
Is the gas leak test fin-
ished?
It may result in insufficient
cooling.
Is the unit fully insulated? Condensate may drip.
Does drainage flow
smoothly?
Condensate may drip.
Does the power supply
voltage correspond to that
shown on the name plate?
The unit may malfunction
or the components burn
out.
Are wiring and piping cor-
rect?
The unit may malfunction
or the components burn
out.
Is the unit safely
grounded?
Risk of electric shock at
electric leakage.
Is wiring size according to
specifications?
The unit may malfunction
or the components burn
out.
Is something blocking the
air outlet or inlet of either
the indoor or outdoor
units?
It may result in insufficient
cooling.
Are refrigerant piping
length and additional
refrigerant charge noted
down?
The refrigerant charge in
the system is not clear.
Items to be checked
Check
Did you explain about operations while showing the
operation manual to your customer?
Did you hand the operation manual over to your cus-
tomer?
The items with
WARNING and
CAUTION marks in
the operation manual are the items pertaining to possi-
bilities for bodily injury and material damage in addition
to the general usage of the product. Accordingly, it is
necessary that you make a full explanation about the
described contents and also ask your customers to read
the operation manual.
