Connection variations of
indoor unit
The units are factory filled with
dry nitrogen to monitor for
leaks. The pressurised nitrogen
is released when the union nuts
are loosened.
ATTENTION
Unit installation
The indoor unit is attached by
means of a wall bracket, under
consideration of air discharge side
located in the lower part.
1. Mark the mounting points on
the structurally permissible
building sections according to
the dimensions of the unit.
2. Remove the housing's break
out opening if necessary.
3. Connect the refrigerant
lines, electrical cables and
condensation line to the indoor
unit as described below.
4. Hang the indoor unit onto the
wall bracket by tilting it back
slightly and then by pressing
the bottom part of the unit
against the bracket (figure 5).
5. Check that the unit is level.
Wall bracket
for indoor unit
The wall bracket for the unit must
be attached with suitable screws
and anchors.
Installation
Installation may only be
performed by authorised
specialists.
NOTE
Oil return measures
If the outdoor component is
installed at a higher level than
the indoor unit, suitable oil return
measures must be taken. This is
normally accomplished by creating
a bend in the oil line, installed at
every 2.5 metres of rise.
5 Connecting
Connecting the refrigerant
lines
The on-site connection of the
refrigerant lines is carried out at
the rear of the unit.
It may be necessary to fit
a reducing or extending adapter to
the indoor units. These fittings are
included with the indoor unit as an
accessory kit. Once installed, the
connections should be sealed to
prevent vapour diffusion.
The following instructions describe
the installation of the refrigerant
circuit and the assembly of the
indoor unit and the outdoor
component.
1. The required pipe diameters are
given in the table "Technical
data".
2. Remove the factory-fitted
protective caps and union nuts
on the connections and use
these during installation.
3. Before flanging the refrigerant
lines, ensure that the union nut
is on the pipe.
4. Prepare the refrigerant lines as
shown below
(Page 19, figures 6+7)
