1.4  PURPOSE OF THIS MANUAL
The air conditioning system should only be installed by qualied 
personnel, with  the  necessary  resources, tools and  equipment, 
who are familiar with the safety procedures required to success-
fully carry out the installation.
PLEASE  READ  AND  FAMILIARISE  YOURSELF  WITH  THE 
MANUAL BEFORE STARTING WORK ON THE INSTALLATION 
OF THE AIR CONDITIONING SYSTEM. Failure to observe the 
instructions for  installation,  use  and  operation  described  in  this 
Manual may result in operating failure including potentially seri-
ous faults, or even the destruction of the air conditioning system.
It is assumed that the air conditioning system will be installed and 
maintained by responsible personnel trained for the purpose. If 
this is not the case, the customer should include all the  safety, 
caution and operating signs in the native language of the person-
nel responsible.
Do not install the unit in the following places, as this may lead to 
a re, deformities, rusting or faults:
•  Places where oil is present (including oil for machinery).
•  Places with a high concentration of sulphurous gas, such as 
spas.
•  Places where ammable gases may be  generated  or  circu-
late.
•  Places with a saline, acidic or alkaline atmosphere.
Do not install the unit in places where silicon gas is present. Any 
silicon gas deposited on the surface of the heat exchanger will re-
pel water. As a result, the condensate water will splash out of the 
collection tray and into the electrical box. Water leaks or electrical 
faults may eventually be caused.
Do not  install  the  unit in  a  place  where the  current  of  expelled 
air directly affects animals or plants as they could be adversely 
affected.
