12 INSTALLATION OF THE OUTDOOR UNIT
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.
12.3 CONNECTION OF THE PIPE FOR THE DRAINAGE OF THE
CONDENSED WATER
Whilst the unit is running with the heat pump function, con-
densation forms in the outdoor unit and has to be drained.
• Insert the elbow included in the supply in the hole provided
at the bottom of the outdoor unit and turn it 90º to fix it
(see Figure 1.).
Fig. 12.2 Assembly of the drainage elbow for condensed water.

• Mount the drainage hose ensuring that it leaves the
equipment at a tilt.
• Verify the correct drainage of the water by pouring the
water into a collection tray located at the bottom of the
outdoor unit.
• Protect the condensed water hose with thermal insulation
to avoid freezing.
