Refrigerant piping

WARNING WARNING
• THIS SYSTEM ADOPTS HFC REFRIGERANT (R32)
WHICH DOES NOT DESTROY THE OZONE LAYER.
M8
• Therefore during installation work prevention of the
invasion of water, dust, former refrigerant or oil is of a
paramount importance.
To prevent the charging of incorrect refrigerants into
the system the service valve connection ports have
also increased in size.
• The use of R32 or R410A tools is required for correct
installation of the system.
• The use of the correct pipe sizes and wall thicknesses
of copper pipe work is required for the correct
installation of the system.
CAUTION
• Ensure all refrigerant pipes are protected from the
invasion of dust and water.
• Ensure all pipe work connections are tightened to the
required torque settings detailed in this section.
• Perform an air tight test using Oxygen Free Nitrogen
± 1°
(OFN) only.
• Evacuate the air in the pipe work using a vacuum
pump.
• Check for refrigerant gas leaks at all connections
throughout the pipe work.
NOTE
The Air to Water Heat Pump System uses R32
refrigerant. It is important that copper pipes used for
refrigerant piping have the following wall thickness:
• 0.8 mm for Ø6.4 mm and Ø12.7 mm
• 1.0 mm for Ø15.9 mm
