FOR THE FOLLOWING ITEMS, TAKE SPECIAL

CARE DURING CONSTRUCTION AND CHECK

AFTER INSTALLATION IS FINISHED.

a. Items to be checked after completion of work

Also review the “SAFETY PRECAUTIONS”

b. Items to be checked at time of delivery

c. Points for explanation about operations

2-4 NOTE TO 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.

• Do not use in seaside locations with a lot of salt in the air, fac-

tories and other locations where the voltage fluctuates, in

automobiles, or in marine vessels.

3. SELECTING INSTALLATION SITE

When it may exceed 30°C and RH80% in the ceiling or fresh air

is inducted into the ceiling, an additional insulation (Thickness

10mm or more of glasswool or polyethylene form) is required.

(1) Select an installation site where the following conditions are

fulfilled and that meets with your customer’s approval.

•

Where is resistible against weight of the unit.

•

In the upper space (including the back of the ceiling) of the

unit where there is no possible dripping of water from the

refrigerant pipe, drain pipe, water pipe, etc.

• Where optimum air distribution can be ensured.

• Where nothing blocks the air passage.

• Where condensate can be properly drained.

• If supporting structural members are not strong enough

to take the unit’s weight, the unit could fall out of place

and cause serious injury.

• Where the false ceiling is not noticeably on an incline.

• Where there is no risk of combustible gas leakage.

• Where sufficient clearance for maintenance and service

can be ensured. (Refer to Fig. 1)

• Where the total piping length involving indoor unit and

outdoor unit is below the allowable piping length.

(See the installation mamual included with the outdoor

unit for “6. REFRIGERANT PIPING.”)

• Locations where a maintenance hole can be installed.

(Refer to Fig. 2)

CAUTION

• Install the indoor and outdoor units, power supply wires and

transmission wires 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.)

(2) Use suspension bolts for installation. Check whether

the ceiling is strong enough to support the weight of

the unit or not. If there is a risk, reinforce the ceiling

before installing the unit.

Items to be checked

If not properly done, what is

likely to occur.

Check

Are the indoor and outdoor unit

fixed firmly?

The units may drop, vibrate or

make noise.

Is the gas leak test finished?

It may result in insufficient cool-

ing.

Is the unit fully insulated? Condensate water may drip.

Does drainage flow smoothly? Condensate water 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 correct?

The unit may malfunction or

the components burn out.

Is the unit safely grounded? It may result in electric shocks.

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 cool-

ing.

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 instruction

manual to your customer?

Did you hand the instruction manual over to your customer?

The items with WARNING and CAUTION marks in the instruc-

tion manual are the items pertaining to possibilites for bodily injury

and material damage in addition to the general usage of

the product. Accordingly, it is necessary that you make a full expla-

nation about the described contents and also ask your customers to

read the instruction manual.
