Caution!

The connections of the room air conditioner are equipped with various self-sealing single couplings. (The

connection valve on the outdoor unit of the device has a locking device, the indoor unit does not.) Care must

be taken to ensure that the split pipes are connected using the correct connections.

Cooling system connections should be made first between the indoor unit and the split pipes and then

between the split pipes and the outdoor unit. This order must also be observed if you use your own refrigerant

pipes (without couplings)!

The split pipes (gas and liquid pipes or suction and pressure pipes) each have a “male” and a “female” half

with a Schrader valve connection.

The split pipes cannot be connected incorrectly in combination with the coupling halves already pre-installed

in the split devices (provided that the correct split pipes are used), as only one combination of two matching

coupling halves is possible. Split pipes of the same size (size of coupling) can be joined together to a

maximum length of 20 m.

After connection, these couplings may be separated or disconnected only by a qualified technician or

the authorised after-sales service (refrigerant leakage)!

Installation instructions:

The refrigerant pipes should first be unrolled carefully

against the winding direction to their full length (Do not

pull them apart in the axial direction!).

Step 1:

Lay the suction and pressure pipes between the outdoor and indoor units. The pipes may not have more than

3 bends in succession and a total of not more than 12 bends over their entire length.

The number of bends should be kept to a minimum. The radius of the bends must be at least 3.5 times the

external diameter. The pipes should not be bent more than 3 times in the same place as the material then

suffers fatigue and becomes cracked.

Step 2:

Remove the dust caps and plugs.

Step 3:

If necessary, clean the fitting surfaces of the couplings and the threads with a clean cloth to avoid particles of

dust or other foreign bodies entering the system.

Step 4:

Moisten the membranes of the male half of the coupling and the rubber seal with refrigerant oil. In order to

ensure that the threads fit together perfectly, first screw the two halves together by hand until the thread has

engaged properly or until the two halves of the coupling membrane meet and turning becomes more difficult

(the coupling membranes are penetrated at this point).
