yourself, it is imperative that you contact your
customer service team or a refrigeration
contractor.
앬 Important! The EQ valves are only designed for
one-time installation. Their seal cannot be
guaranteed if they are installed on more than one
occasion. This will also void the warranty.
5.2 Connecting the refrigerant lines to the indoor
device
Route the refrigerant lines from the indoor device to
the outdoor device.
Notes:
앬 To avoid confusion, the connections for the
refrigerant lines are marked “A”, “B”, “C” and “D”.
Always join connections to those with matching
markings.
앬 Route the refrigerant lines from the indoor device
to the outdoor device.
앬 The minimum bending radius for the refrigerant
lines is 150 mm and only bend the refrigerant
lines once. If too small a bending radius is used
or the lines are bent more than once, the
refrigerant line may become porous, kink or
break.
앬 The refrigerant lines must be connected to the
valves on the indoor device with as little stress
as possible.
앬 Depending on the local circumstances, it may be
a good idea to place the refrigerant lines with
their plastic seals in place before installation from
outside through the hole in the wall and to the
wall hole pipe. The instructions set out below
must be changed accordingly in this case.
1. Do not remove the plastic seals from the indoor
device and the appropriate refrigerant line until
immediately before you connect them. Refer to
the markings on the connections.
2. Fig. 20: Align the refrigerant lines correctly so
that they line up with the valves and are not
stressed. Place the screw connector on the
refrigerant line just on to the thread on the
outdoor equipment and tighten the first few
threads by hand.
3. Fig. 21 / 22: Tighten the screw connections with
an open-ended spanner. Hold the points marked
“X” using a 24 mm open-ended spanner and turn
the nuts only at the positions marked “Y” using a
27 mm open-ended spanner.
b) Ensure that the screw connectors do not skew
as you tighten them and work quickly.
Important! Since the coupling works with tapping
rings, it may leak if you undo and reconnect the lines.
This will also void the warranty.
After completing steps 1 – 3, check that all the
connections are sealed correctly using leak detection
spray or soap suds. If any bubbles form, the system
has a leak and the screw connectors must be
retightened using an open-ended spanner.
4. Bundle all the lines together to form a parcel of
lines.
Notes:
앬 Bend and position the condensation hose
carefully. (Fig. 23)
앬 Both refrigerant lines must be insulated at the
connection points.
앬 The condensation drain hose must be connected
below the refrigerant line.
앬 It must be ensured that none of the pipes on the
rear of the indoor device leak.
앬 It must be ensured that the condensation drain
hose is positioned at the lowest point of the
insulation package. The hose must be separated
from the cables and connection pipe so that no
condensation can run over the cables and pipe.
앬 Do not cross the mains cable with other cables.
앬 Please note that the power cable is not to be fed
through to the outside. All tubes, electric cables
and the drainage water hose have to be wrapped
with the supplied protective tape. Depending on
whether the lines are right-hand or left-hand
versions, the corresponding bushing
preparations must be removed from the indoor
device.
앬 The package of lines/hoses is to be laid between
the housing of the indoor device and the wall (fig.
24).

5. Guide the parcel of lines through the supplied
wall passage and through the hole in the wall
(Fig. 25/26).
6. Attach the indoor device to the mounting plate.
The top hook (Fig. 26 / Item A) on the mounting
plate must be securely attached to the rear of the
indoor device. After you have completed the
installation work, press the indoor device into the
bottom mount (B).
