12.2 CONNECTION OF THE REFRIGERANT PIPES

NOTE!
Installation is easier if the gas suction pipe is connected
up first. The suction pipe is the thickest one.
• Mount the outdoor unit in the designated site.
• Remove the protection hoods from the refrigerant joints in
the outdoor unit.
• Carefully bend the installed pipe towards the outdoor
unit.
WARNING!
Danger of breakdowns or malfunction. Danger of wear
in the refrigerant pipes.
Bend the pipe carefully to prevent choking or breaks.
• Cut the pipes, leaving enough extra piping hanging over to
enable the unit to be hooked up at the outdoor unit joins.
• Flare the refrigerant pipe when installed.
• Join the refrigerant pipes to the corresponding outdoor unit
connection.
• Insulate the refrigerant piping correctly and separately. To
do so, cover any possible cuts with masking tape or
insulate any bare refrigerant piping with the corresponding
insulation material used for cooling.
