IMPORTANT NOTICE
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.

PMML0477 rev.2 - 11/2017
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
