ENGLISH

During operation:
• Avoid an extended period of exposure to a direct air flow.
• Do not insert fingers, rods or other objects into the air outlet

or inlet. As the fan is rotating at high speed, it will cause
injury. Before cleaning, be sure to stop the operation and turn
the breaker OFF.

Do not use any conductor as fuse wire. This could cause a
fatal accident.

During thunderstorms, disconnect and turn off the circuit
breaker.

Do not attempt to operate the unit with wet hands. This could
cause fatal accident.

Do not direct the cool air coming out from the air conditioner
to household heating appliances (stoves, electric kettles,
ovens, etc.), as this may affect their operation.

Please ensure that the outdoor mounting frame is always

stable, firm and without defects. Otherwise, the outdoor unit

may collapse and cause damage and injury.

Do not splash or direct water to the body of the units when
cleaning them, as this may cause short circuit.

Do not use any aerosol or hair sprays near the indoor unit.

Their chemicals can adhere to the fins of the heat exchanger
and block the flow of evaporation water to the drain pan.

Water will drop on the tangential fan and splash out from the
indoor unit.

Switch off the units and turn off the circuit breaker during
cleaning.

Do not climb on the outdoor unit or put objects on it.

Do not put water containers (like a vase) on the indoor unit. If
water drips into the unit, it will damage the inside and cause
short circuit.

When operating the unit with the door and windows opened
(relative humidity constantly above 80%) and with the air

deflector facing down or moving automatically for a long
period of time, water will condense on the air deflector

and drip down occasionally. This will wet your furniture.
Therefore, do not operate under such condition for an
extended time.

The preset room temperature cannot be achieved if the
amount of heat in the room exceeds the cooling or heating
capacity of the unit (for example, if more people enters in the
room, if heating equipment is used, etc.).

SAFETY PRECAUTION

Check that all the information necessary for the correct
installation of the system is included in the Installation and
Operation Manuals provided with the outdoor and indoor
units. Please contact your distributor if it is not the case.

The installation of refrigerant tubing shall be kept to a
minimum. Refrigerant tubing outside the cabinet shall be
protected to avoid mechanical damage and shall not be
installed in an unventilated space. It shall not be handled
or used for carrying during moving of the units. Flexible
refrigerant connectors (such as connecting lines between
the indoor and outdoor unit) may be displaced during normal
operation.

Low temperature solder alloys, such as lead/tin alloys, are 
not acceptable for pipe connections.
Brazed, welded or mechanical connection shall be made 

before opening the valves to permit refrigerant to flow 

between refrigerant system parts. When mechanical 
connectors are reused indoors, sealing parts shall be 

renewed. When flared joints are reused indoors, the flare 

parts shall be re-fabricated. Mechanical connections shall be 
accessible for maintenance purposes.
If any part of the system is installed in an unventilated area, 
it shall be so constructed that should any refrigerant leak, it 

will not stagnate so as to create a fire or explosion hazard. 

Any required ventilation opening shall be kept clear of 
obstruction. Compliance with national gas regulations shall 
be observed.

ELECTRICAL INSTALLATION

The electrical installation must be performed according to
this Installation Manual and all the relevant regulations and
standards. Failure to follow these instructions can result in
shortage of capacity and reduced performance, leading to

electric shock and fire.

Do not install the unit in the following places, as this may

lead to the occurrence of fire, deformations, rusting or
operation failure:

 

-

Places where oil is present (including oil for machinery)

 

-

Places with a high concentration of sulphurous gas, such
as spas

 

-

Places with a saline, acidic or alkaline atmosphere

 

-

Places where flammable gases may be generated or 

circulate

 

-

Places where silicon gas is present (depositions of silicon 
gas on the surface of the heat exchanger act as a water 
repellent, resulting in condensate water splashing out of 
the collection tray and into the electrical box)

SERVICING

Do not carry out maintenance, service and repair operations
by yourself. These operations shall be performed only by

qualified workers with the suitable tools and resources.

Work shall be undertaken under a controlled procedure so
as to minimise the risk of ignition. All maintenance staff and
other staff in the area shall be instructed on the nature of

work being carried out. Work in confined spaces shall be

avoided.

Ensure that the conditions within the area have been made

safe by control of flammable material. The area shall be

checked with an appropriate refrigerant detector prior to

and during work, to ensure that a potentially flammable

atmosphere is detected. The leak detection equipment used

shall be suitable for use with flammable refrigerants (i.e.,

non-sparking, adequately sealed and intrinsically safe)

• Appropriate fire extinguishing equipment shall be available

on hand if any hot work is to be conducted. Please have a
dry powder or CO2 extinguisher next to the charging area.

Any source of ignition which may lead to the risk of fire
