Check leakage at the valve connector in the piping connection part
by using soap bubbles.
Carry out heat insulation treatment for the pipes at the gas and
liquid sides respectively. Pipes on the liquid and air sides have a
low temperature during cooling. Take sufficient insulation measures
to prevent condensation (see the figure on the right).

1. The pipes at the gas side must use heat insulation material that
can withstand high temperature up to at least 120°C.
2. The attached insulation material for the part of the IDU where the
pipe connects must undergo heat insulation treatment that leaves no
gaps.
The electric circult must be installed RCCB and manual switch.
6 ELECTRIC CONNECTION
Use special power supply for the air conditioner. Design power
supplies specific to the indoor unit and outdoor unit. The supply
voltage must comply with the nominal voltage.
The external supply circuit of the air conditioner must have a
ground wire, and the power supply ground wire of the indoor unit
must be connected with the external ground wire firmly.
The wiring must be performed by professional technicians
according to the circuit diagram labels.
Distribute the wires according to the relevant electric technical
standards promulgated by the State, and set the Residual
Current-operated Circuit Breaker (RCCB) properly.
The power wire and the signal wire shall be laid out neatly and
properly, without mutual interference or contacting the
connection pipe or valve.
No power cable is attached to this equipment. The user can
select the power cable by reference to the stipulated power
supply specifications. No joint of wires is allowed.
Upon completion of wire connection, double check it and then
connect the power supply.
An all-pole disconnection device which has at least 3mm
separation distance in all pole and a residual current
device(RCD)with the rating of above 10mA shall be incorporated
in the fixed wiring according to the national rule.
The appliance shall be installed in accordance with national
wiring regulations.
CAUTION
NOTE
Table 6-1
Please identify outdoor main unit and auxilary unit. Only main unit
connects with signal wire of indoor unit. Users should adjust the
dial on electric control board of outdoor unit as follows, otherwise
incorrect adjustment may cause malfunction.
Ground the air conditioner properly in case to affect its
anti-interference function
