REFRIGERANT PIPE INSTALLATION
The system is not provided with pipework or interconnecting wires, which should be supplied by
the engineer and cut to the appropriate size. The unit is precharged for 5 metres of pipework and
refrigerant must be added if the pipe length is more than 5 metres. This operation can only be
performed by a professional F-Gas engineer, for the additional gas amount, see the below:
FLARING THE PIPES
1. Cut the refrigerant pipe to the correct length using a pipe cutter.
2. Ensure the end of the pipe is smooth.
3.
Slide the connecting nut onto the pipe before flaring with an appropriate tool, to create a
flare with the requirements below.
