1. GENERAL INFORMATION
PRECAUTIONS
Installing and servicing of air conditioning equipment can be hazardous due to system
pressure and electrical components. Only trained and qualified service personnel should
install or service this equipment.
Untrained personnel can perform basic maintenance function such as cleaning coil and
filters. Trained service personnel should perform all other operations.
When working on air conditioning equipment, observe precautions in the literature, tags
and labels attached to the unit.
WARNINGS
•The operating voltage of electrical power supply should be within the voltage mentioned on unit
nameplate data.
•The capacity of electrical kWh counter should be larger than the operating currents required for
air conditioner(s) and any other electrical domestic appliances in use simultaneously from the
same supply.
•The installation of electrical distribution box after the electrical KWH counter is necessary to
properly distribute the electrical loads. The electrical distribution box should be equipped with
circuit breakers according to the electrical loads. For each installed air conditioner, a separate
circuit breaker with its own overload should be installed on the electrical distribution box.
•The installation of two-pole automatic circuit breaker is necessary to operate the air conditioner.
The circuit breaker must be installed to be far away from any flammable materials (curtains…etc.).
The circuit breaker size must be suitable for air conditioner.
•Disconnect the electrical mains supply prior to any maintenance operations or prior to handling
any internal unit parts.
•The manufacturer declines any liability for damage resulting from modifications or errors in the
electrical or refrigerant connections, made during the installation, or from the improper use of this
equipment. This will void the unit warranty immediately.
•Failure to observe electrical safety codes may cause a fire hazard in case of short circuits.
•This system will only work safety and correctly, if installed and tested by qualified personnel.
•Do not open the electronic remote controller to avoid possible damage. In case of malfunction
contact a qualified service engineer.
•The unit contains rotating equipment (fan). Ensure that this is out of reach for children.
•Be conscious of the room temperature and general comfort, particularly when this is used near
children, senior or handicapped people.
•For correct use, the air conditioner must operate within the temperature limits indicated in the
table “Operating Limits” included in the installation manual. Incorrect use of the system outside
these limits may cause malfunction and dripping water.
