Removal
• Do not relocate the unit because this unit is one component part installed in the specified
fixed equipment as an interpretation of the EMC Directive.
• When the unit is to be removed, do not remove it yourself but contact a qualified installer or a
qualified service person. Failure to remove the unit properly may result in a fire, electric
shocks, injury, water leakage, and/or refrigerant leakage.
• Be sure to use a refrigerant recovery machine to recover the refrigerant when removing or
repairing.
• Only a qualified installer or qualified service person is allowed to remove the unit. It is
dangerous for the unit to be removed by an unqualified individual since a fire, electric shocks,
injury, water leakage, and/or refrigerant leakage may result.
(When the unit is to be removed, do not remove it yourself but contact a qualified installer or
a qualified service person. Failure to remove the unit properly may result in a fire, electric
shocks, injury, water leakage, and/or refrigerant leakage.)
CAUTION
To disconnect the appliance form the main supply
• This appliance must be connected to the mains power supply by means of an circuit breaker
with a contact separation of at least 3 mm.
New refrigerant
• This unit adopts the new HFC refrigerant (R32) which does not destroy ozone layer.
• The characteristics of R32 refrigerant are; easy to absorb water, oxidizing membrane or oil,
and its pressure is approx. 1.6 times higher than that of refrigerant R22. Accompanied with
the new refrigerant, refrigerating oil has also been changed. Therefore, during repair work,
be sure that water, dust, former refrigerant, or refrigerating oil does not enter the refrigerating
cycle.
• To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting
sections of charging port of the main unit and installation tools are changed from those for
the conventional refrigerant.
• Accordingly the exclusive tools are required for the new refrigerant (R32).
• For connecting pipes, use new and clean piping designed for R32, and please care so that
water or dust does not enter.
Installation
• Certainly lay the drain pipe for perfect draining. Bad drainage may cause flooding around the
unit and getting ground wet.
• Make sure to connect the unit to an exclusive power supply of the rated voltage, otherwise
the unit may break down or cause a fire.
• After the installation work has been completed, have the installer explain about the circuit
breaker positions. In the event that error has occurred in the unit, set the circuit breaker to
the OFF position, and contact a service person.
Operation
• Do not use this unit for special purpose such as preserving food, precision instruments, art
objects, breeding animals, car, vessel, etc.
• Do not touch any switches with wet finger, otherwise you may get an electric shock.
• If the unit will not be used for a considerably long time, turn off the circuit breaker, for safety.
In addition, bleed the pipe of water or fill with antifreeze solution in the pipe to prevent
breakage caused by freezing.
