6.4 System Piping Connection

Piping connection must be carried out for each outdoor unit.

NOTE:

Verify that the refrigerant piping is connected in the same refrigerant circulation system.

Figure 6.1 Refrigerant Piping Connection

●

Refrigerant piping directions.
Fix the refrigerant piping properly to avoid vibration and

external force on the stop valve.

(1) Refrigerant piping can be connected in three

directions of the outdoor unit:
Front: Connect the piping from the piping entrance

at the unit chassis and then run it through the front

opening of the chassis.
Bottom: Directly connect the piping from the piping

entrance at the unit chassis.
Rear: Connect the piping from the piping entrance

at the unit chassis and then run it through the rear

opening of the chassis.

(2) Operate the stop valve as per Clause 6.4.5.
(3) Refer to section 5.1 and "Installation and

maintenance manual" for piping connection.

Rear side

(4) If the piping is connected from the front side of the

unit, the connection piping of the unit should be

sealed completely with thermal insulation tube so as

to prevent water or snow from entering into the unit.

(5) If the piping is connected from the bottom or rear

side of the unit, need apply thermal insulation tube

to the piping which is going through the bottom

of the unit, so as to prevent water or snow from

entering into the unit.

Gas pipe

Piping baffle

Seal the pipe with

cotton insulation and

ensure no gap exists
