SAFETY PRECAUTION

WARNING

z

Installation and maintenance should be performed by
qualified persons who are familiar with local code and
regulation, and experienced with this type of
appliance.

z

All field wiring must be installed in accordance with
the national wiring regulation.

z

Ensure that the rated voltage of the unit corresponds
to that of the name plate before commencing wiring
work according to the wiring diagram.

z

The unit must be GROUNDED to prevent possible
hazard due to insulation failure.

z

All electrical wiring must not touch the water piping or
any moving parts of the fan motors.

z

Confirm that the unit has been switched OFF before
installing or servicing the unit.

z

Risk of electric shock, can cause injury or death.
Disconnect all remain electric power supplies before
servicing.

z

DO NOT pull out the power cord when the power is
ON. This may cause serious electrical shocks which
may result in the fire hazards.

z

Keep the indoor and outdoor units, power cable and
transmission wiring, at least 1m from TVs and radios,
to prevent distorted pictures and static. {Depending
on the type and source of the electrical waves, static
may be heard even when more than 1m away}.

CAUTION

Please take note of the following important points when
installing.

z Ensure that the drainage piping is connected properly.

If the drainage piping is not connected properly, it may
cause water leakage which will dampen the furniture.

z Sharp edges and coil surfaces are potential locations

which may cause injury hazards. Avoid from being in
contact with these places.

z Tightening torque should not be too high when connecting

water pipes, in order to avoid brass deformation or
water-leakage by torsion split.

z W ater coil not used during winter season shall be drained,

or anti-freezing solution shall be added to the water circuit
to avoid freezing.

z Before turning off the power supply set the remote

controller’s ON/OFF switch to the “OFF” position to
prevent the nuisance tripping of the unit. If this is not

done, the unit’s fans will start turning automatically when
power resumes, posing a hazard to service personnel or
the user.

z Ensure the color of wires of the outdoor unit and the

terminal markings are same to the indoors
respectively.

z IMPORTANT: DO NOT INSTALL OR USE THE AIR

CONDITIONER UNIT IN A LAUNDRY ROOM.

NOTICE

Disposal requirements

Your air conditioning product is marked with this symbol. This means that electrical and electronic products
shall not be mixed with unsorted household waste.
Do not try to dismantle the system yourself: the dismantling of the air conditioning system, treatment of the
refrigerant, of oil and of other parts must be done by a qualified installer in accordance with relevant local
and national legislation. Air conditioners must be treated at a specialized treatment facility for re-use,
recycling and recovery. By ensuring this product is disposed of correctly, you will help to prevent potential
negative consequences for the environment and human health. Please contact the installer or local
authority for more information.
Batteries must be removed from the remote controller and disposed of separately in accordance with
relevant local and national legislation.

General features and technical data

Their quiet operation, compact dimensions and particularly low height, make units ideal for false ceiling
installation even in vintage buildings with narrow ceiling spaces. Units are standard supplied with sound
proofed suction plenum, air filter and extra-long drain pan. Centrifugal fans, with forwards curved blades, are
statically and dynamically balanced and moved by single-phase motor with three speeds (standard) plus one
(optional).

The availability of 2&4 pipe versions, the possibility to change connection side on field and accessories like
electronic thermostat and water on/off valves, provides the maximum flexibility and ease of installation.
