disassembling work.

Step Procedure Points

1. Disconnecting the

wooden base. Caution!

In pump-down work, be sure

to stop the compressor

before disconnecting the

refrigerant pipe. If the

refrigerant pipe is

disconnected with the

compressor being operated

generate an over-pressure in

refrigeration cycle, thus

resulting in pipe rupture or

accidental injury.

body slightly and pull

out the drain hose. (In

the case of left piping)

 Place a plastic bag under

the drain pan to prevent

embedded in the wall,

disconnect the drain hose

beforehand.

Disconnect the pipe

connection with 2 pair

of spanners.

Caution!

From the point of view

of environmental

protection, be sure to

use a vacuum pump

for air purging.

 Carry out the removal works

with 2 pair of spanners.

 When the pipes are

disconnected, protect the

both openings of pipe side

and unit side from entering

of moisture.
