9.4 INSTALLATION OF THE CONDENSED WATER PIPE
9.4.1 HANDLING THE CONDENSED WATER PIPE
WARNING!
Danger of breakdowns or malfunction. Danger of
incorrect drainage of the condensed water and wear of
materials due to dripping water.
Take the following points into consideration:
- Ensure that air circulates through the condensed
water pipe in order to guarantee that the water can
be freely released. Otherwise, the condensed water
could leak through the indoor unit body.
- Mount the pipe without bending it in order to avoid
blockage.
- If the water pipe is channelled outdoors, ensure that
it is insulated against freezing.
- If the condensed water pipe is installed in a room, fit
thermal insulation.
- Avoid installing the condensed water pipe with an
ascending bend.
- Avoid installing the condensed water pipe with it
free end submerged in water.
- Avoid installing the condensed water pipe with
crimping.
- Install the condensed water pipe in such a way that
the distance of its free end from the floor is at least
5 cm.
- Install the condensed water pipe in such a way that
its free end is kept away from unpleasant odours to
ensure that they do not penetrate the room.
9.4.2 LAYING OF THE CONDENSED WATER PIPE
NOTE!
The indoor unit is fitted with a condensed water removal
pump.
NOTE!
Use a pipe whose diameter is at least the same as the
diameter of the indoor unit connection (polyethylene
pipe: inner diameter 25 mm, outer diameter 32 mm).
• Plan the layout of the condensed water pipe taking into
account the indications in section 9.4.1.
-Ensure that the pipe is as short as possible.
- Ensure that the minimum inclination from the indoor unit
is at least 1%.
• Mount the pipe supports taking into account the distances
and inclinations indicated in figure 9.1.

9.5 INSTALLATION OF THE REFRIGERANT PIPES
9.5.1 HANDLING THE REFRIGERANT PIPES
DANGER!
Danger of burns and eye injuries.
In the event of soldering, use suitable protection
equipment (protective soldering mask, soldering
gloves, solderer clothing).
WARNING!
Danger of breakdowns or malfunction. Danger of wear
in the refrigerant pipes.
To ensure that the refrigerant pipes do not wear take
the following points into consideration:
- Use pipes specifically intended for cooling.
- Ensure that the pipes are clean, dry and polished on
the inside.
- The insulation of the pipes should be done using
specific insulation for cooling.
- Observe the minimum and maximum pipe distances
for each model.
- Do not bend the pipes where possible. When
bending them, keep the radius as wide as possible
to minimise load losses.
- If soldering, do so using strong welding (copper-
silver alloy). During the soldering process a stream
of dry nitrogen should be run through the inside of
the pipes in order to avoid rusting.
- Only cut the refrigerant pipes using pipe cutters and
always keep the pipe ends covered.
- Any flaring work should be performed meticulously
in order to avoid subsequent losses of gas through
the pipes.
- When reviving keep the pipe opening directed
downwards in order to prevent shavings from getting
into the pipes.
- Mount the joining tubes carefully, ensuring they
cannot become displaced. Ensure that they will not
cause traction in the joins.
- Equip the refrigerant pipes (inflow and outflow)
separately and with high density heat insulation.
-Carefully squeeze the flaring connector, centring the
flaring cone and the flanged nut. Applying excessive
force without correctly centring can damage the
thread and cause a reduction in the water tightness
in the join.
Note!
In specialised dealers you will find refrigerant pipes
which are thermally insulated as a Saunier Duval
accessory.
9.5.2 LAYING OF THE REFRIGERANT PIPES
NOTE!
Ensure that after mounting there is enough space for
accessing the indoor unit connections.
• Carefully bend the installation pipe in the right direction.
WARNING!
Danger of breakdowns or malfunction.
Danger of wear in the refrigerant pipes.
Bend the pipe carefully to prevent choking or breaks.
• Position the pipes in the runoff provided.
• Cut the pipes, leaving enough extra piping hanging over to
enable the unit to be hooked up at the indoor unit joins.
•Insert the nut in the refrigerant pipe and carry out the
flaring.
• Insulate the refrigerant piping correctly and separately
(figure 9.2). To do so, cover any possible cuts with masking
tape or insulate any bare refrigerant piping with the
corresponding insulation material used for cooling.
