(5) Insulation of connecting portion
1) Cover the connecting portion of the refrigerant piping with the pipe cover and seal them.
If neglecting to do so, moisture occurs on the piping and water will drip out.
2) Finishing and fixing
a) Tie up the piping with wrapping tape, and shape it so that it
conforms to which the pipe is attached.
b) Fix them with clamps as right figure.

7.5.5 Test run

(1) Check carefully for gas leakage before performing the trial operation.
(2) Make sure that drain flows properly. (Right figure)
(3) If power source voltage is low and difficult to start air conditioner, ask your
local electric power company to raise voltage. (Of it is not correct there may
occur breaker trip or bourning.)
(4) Make sure that power source is wired as exclusive use for air conditioner and
there is no looseness or play between plug socket and plug. (Plug socket is to
be purchased locally.)
(
When there is something wrong with the electric outlet and if the insertion of
the electric plug is insufficient, there may occur a burn out.
(5) 3 minutes delay circuit operation under the following conditions:
(a) When the air conditioner is stopped by pressing ON/ OFF switch.
(b) When thermostat actuates.
(c) When operation is changed from cooling or dry to fan.
(6)
Explain well the correct usage of the air conditioner carefully to the customer
following the instruction manual.
