Precautions for safety

 General safety precautions
Ensure that all Local, National and International regulations are satisfied.
• Read the "Precautions for safety" carefully before installation.
• The precautions described below include the important items regarding safety – Observe
them without fail.
• After the installation work has been completed, perform a test run to check for any problems.
Follow the Owner's Manual to explain how to use and maintain the unit to the customer.
• Turn off the main power supply switch (or breaker) before unit maintenance.
• Ask the customer to keep the Installation Manual along with the Owner's Manual.
 Refrigerant precautions
• If a refrigerant leak is suspected contact the dealer who supplied the system, in the case of a
recharge of refrigerant ask service personnel for details of the leak and confirmation of the
repairs completed.
The refrigerant used in the system is harmless.
• Generally the refrigerant does not leak, however, if the refrigerant should leak into a room and
a heater or stove burner in the room is lit, toxic gas may be generated.
• Do not install the system in a location subject to a risk of exposure to a combustible gas.
If a combustible gas leaks and stays around the unit a fire may occur.
• Install the refrigerant pipe securely during installation and before operation.
If the compressor is operated with no pipe work connected and valves open the compressor
will suck air which would result in over pressurization of the system which may result in
bursting or injury.
Observe the same precautions for refrigerant recovery work (pump back procedure to outdoor
unit) and do not disconnect pipe work until refrigerant is recovered and valves closed.
