INSTALLATION

 

SITE

When the conditions in the ceiling are exceeding 30°C and a relative
humidity of 80%, or when fresh air is inducted into the ceiling, an
additional insulation is required (minimum 10 

mm thickness,

polyethylene foam).

For this unit you can select different air flow directions. It is necessary
to purchase an optional blocking pad kit to discharge the air in 2 or 3
directions.

1

Select an installation site where the following conditions
are fulfilled and that meets your customer's approval.

Where optimum air distribution can be ensured.

Where nothing blocks air passage.

Where condensate water can be properly drained.

Where the false ceiling is not noticeably on an incline.

Where sufficient clearance for maintenance and service can be
ensured.

Where piping between indoor and outdoor units is possible within
the allowable limit. (Refer to the installation manual of the outdoor
unit.)

This is a class A product. In a domestic environment this product
may cause radio interference in which case the user may be
required to take adequate measures.

Keep indoor unit, outdoor unit, power supply wiring and
transmission wiring at least 1 meter away from televisions and
radios. This is to prevent image interference and noise in those
electrical appliances.
(Noise may be generated depending on the conditions under
which the electric wave is generated, even if 1 meter is kept.)

2

Ceiling height

Install this unit where the height of bottom panel is more than
2.5 m so that the user cannot easily touch.

3

Air flow directions

Select the air flow directions best suited to the room and point of
installation. (For air discharge in 2 or 3 directions, it is necessary
to make field settings by means of the remote controller and to
close the air outlet(s). Refer to the installation manual of the
optional blocking pad kit and to the chapter 

"Field setting" on

page 7

.) (See 

figure 2

 (

 = air flow direction))

4

Use suspension bolts for installation. Check whether the
ceiling is strong enough to support the weight of the indoor
unit. If there is a risk, reinforce the ceiling before installing
the unit.

(The installation pitch is marked on the paper pattern for
installation. Refer to it to check for points requiring reinforcing.)

when 

checked

Is the indoor unit fixed firmly?

The unit may drop, vibrate or make noise.

Is the gas leak test finished?

It may result in insufficient cooling.

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 components may burn out.

Are wiring and piping correct?

The unit may malfunction or components may burn out.

Is the unit safely grounded?

Dangerous at electric leakage.

Is the wiring size according to specifications?

The unit may malfunction or components may burn out.

Is nothing 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 might not be clear.

NOTE

Installation is possible with a ceiling opening
dimension of 660 mm (marked with *). However, to
achieve a ceiling-panel overlapping dimension of
20 mm, the spacing between the ceiling and the unit
should be 45 mm or less. If the spacing between
ceiling and the unit is over 45 mm, attach sealing
material in the part marked 

 or recover the ceiling.
