UK PLUGS AND SOCKETS ETC (SAFETY) REGULATIONS 1994,
With regard to Schedule 3, item 7 of the above UK Regulations, this appliance must be permanently connected
to the fixed wiring of the main electrical supply by means other than the use of an approved 13 Amp plug-top as
outlined in the Regulations.
Electrical work must be carried by suitably qualified persons and in accordance with all relevant safety stan-
dards and codes of practice.
We recommend that the power supply for this appliance is derived from a suitably protected dedicated circuit.
CAUTION
• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY
OZONE LAYER.
R410A refrigerant is apt to be affected by impurity such as water, oxidizing membrane, and oils because pres-
sure of R410A refrigerant is approx. 1.6 times of refrigerant R22. Accompanied with adoption of the new refrig-
erant, refrigerating machine oil has been also changed. Therefore, during installation work, be sure that water,
dust, former refrigerant, or refrigerating machine oil does not enter into the refrigerating cycle of new-refrigerant
air conditioner.
To prevent mixing of refrigerant or refrigerating machine oil, the sizes of connecting sections of charging port of
the main unit or installation tools are different from those for the conventional refrigerant. Accordingly, the
exclusive tools are required for the new refrigerant (R410A) as shown below.
For connecting pipes, use new and clean piping materials with high pressure-tight force, which were made for
R410A only, so that water or dust does not enter. Moreover, do not use the existing piping because there are
problems about pressure-tight force and inner impurity in the existing piping.
CAUTION
This appliance must be connected to the mains by means of a switch with a contact separation of at least 3 mm.
