Step 5:

Now use a spanner to firmly connect the two halves of the coupling (essential to ensure the refrigerant circuit

does not leak). Screw locks should then be applied to stop the connection loosening unintentionally through

vibration.

The recommended torques for the couplings for the refrigerant pipes are shown below (It is essential to

secure the two halves of the coupling against loosening!).

Torques

Split pipes with refrigerant couplings with a 5/8“ UNF thread (spanner values SW 19 and

SW 21)  15 – 20 Nm.

Split pipes with refrigerant couplings with a 1 1/16“ UNF thread (spanner values SW 27 and

SW 34)  47 – 54 Nm.

(These torques can be transferred safely only if

the other half of the coupling is firmly fixed using a spanner!)

Step 6:

All the cooling system connections made are to be checked for leaks using the leak search spray supplied

with the split pipes!

The flexible foam insulation (see Scope of Supply) should be wrapped and fixed round each pair of couplings

at the indoor unit (use the insulating adhesive tape for this, and if necessary cable connectors as well).

Insulation is important, as temperatures fall below the dew point during operation (cooling function) and

condensation can be formed.

For longer split pipes, in particular, we recommend joining the insulated gas or pressure pipes using

insulating or fabric adhesive tape (reduces or prevents the vibration of the split pipes during operation and

protects the insulation from UV radiation).

Connection of an additional condensation pipe (if necessary).

An example of how to lay a refrigerant pipe is given below in 3 steps.
