Installation manual

For the following items, take special care during

construction and check after installation is ﬁnished

Notes to the installer

■ Read this manual carefully to ensure correct installation. Be

sure to instruct the customer how to properly operate the system

and show him/her the enclosed operation manual.

■ Explain to the customer what system is installed on the site. Be

sure to ﬁll out the appropriate installation speciﬁcations in the

chapter "What to do before operation" of the operation manual.

SELECTING INSTALLATION SITE (See ﬁgure 1 and 2)

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 there is no risk of ﬂammable gas leaking.

• 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

interference in those electrical appliances. (Electric noise

may be generated depending on the conditions under which

the electric wave is generated, even if 1 meter is kept.)

• When installing the wireless remote controller kit, the

distance between wireless remote controller and indoor unit

might be shorter if there are ﬂuorescent lights who are

electrically started in the room. The indoor unit must be

installed as far as possible away from ﬂuorescent lights.

• Do not place objects that are susceptible to moisture directly

beneath the indoor or outdoor units. Under certain

conditions, condensation on the main unit or refrigerant

pipes, air ﬁlter dirt or drain blockage may cause dripping,

resulting in fouling or failure of the object concerned.

2. Ensure that a protective guard is installed on air suction and air

outlet side to prevent that the fan blades or heat exchanger be

touched.

The protection must comply with relevant European and national

regulations.

3. 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.

PREPARATIONS BEFORE INSTALLATION

1. Relation of ceiling opening to unit and suspension bolt position.

(See ﬁgure 5)

For installation, choose one of the possibilities as listed further.

Standard rear suction (See ﬁgure 6a)

Installation with rear duct and duct service opening (See

ﬁgure 6b)

Installation with rear duct, no duct service opening (See

ﬁgure 6c)

Tick ✓ 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 or heating.

■

Is the unit fully insulated and checked for air leaks?

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.

■

noted down?

The refrigerant charge in the system might not be clear.

This to avoid confusion for future maintenance and serving of

the installation.

■

Are the air ﬁlters ﬁxed properly (when installing with rear duct)?

Maintenance of the air ﬁlters can be impossible.

■
