C. Mounting the outdoor device
It is imperative that you follow the installation
instructions.
1. Before you start installation
앬 Select the location for installation (follow the
previous notes on selecting the location).
앬 Check that the available mains voltage is the
same as the voltage specified on the rating plate.
앬 The maximum possible distance between the
indoor and the outdoor device using the supplied
accessories is 4 m.
앬 If the outdoor device is higher than the indoor
device, make sure that a curve is made in the
coolant tube which is lower than the bottom edge
of the indoor device.
앬 Secure the condensation drain (B) to the base of
the outdoor device using the sealing disc (A).
Drain the water generated when the system is in
heating mode through a hose.
2. Installing the outdoor device
앬 The outdoor device can be fastened to the
ground or to a wall bracket (e.g. special
accessory Art. No. 23.651.57) with dowels and
screws. To do so, use the holes on the device.
3. Connecting the refrigerant line to the outdoor
device
Important.
Refer to section 5.1 which contains the main
instructions for connecting the refrigerant lines.
Notes:
1. Have all service work performed by a specialist
firm only. Request a copy of our list of service
partners for any such work.
2. If ever the voltage carrying cable between the
indoor device and the outdoor device should be
damaged, contact a specialist firm.
3. If the power cable should ever be damaged,
have it replaced by an electrician.
4. Important note:
a) The maximum length of the coolant line in the
basic version is 4 meters.
b) If the outdoor device is higher than the indoor
device, a curve will be required in the coolant
tube which is positioned below the height of the
indoor device.
1. Fig. 28: Remove the connection cover on the
outdoor equipment.
2.
Fig. 29: Do not remove the plastic seals from the
outdoor equipment and the appropriate
refrigerant line until immediately before you
connect them. The mating connections are
marked with identical letters.
3. Fig. 29/30: 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.
Note: The refrigerant lines must be connected to
the valves on the outdoor equipment with as little
stress as possible.
IMPORTANT! Before you continue, it is essential
that you read the following instructions carefully.
4.
Fig. 31/32: Now tighten the bottom screw
connector first and then the top screw connector
using the open-ended spanner.
Hold the points marked “A” using a 24 mm open-
ended spanner and turn the nuts only at the
positions marked “B” using a 27 mm open-ended
spanner.
Notes:
a) Never place the open-ended spanner in the
positions marked “X” (Fig. 33).
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 – 4, 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.
5.
Fig. 34-36: Now remove the cover on the top
valve using a 19 mm open-ended spanner. Open
the valve by turning it counter-clockwise as far as
it will go using a 5 mm Allen key. The valve is
now open. If the valve is not opened fully, the
system may malfunction and suffer damage.
Screw the cover back on to the top valve and
tighten it well to ensure that it is properly sealed.
Important! The conical ring on the valve has an
important sealing function together with the sealing
seat in the caps. Ensure that you do not damage the
cone and that you keep the cap free of dirt and dust.
