▶
Connect each air/brine collector to a three-phase 400 V
AC network with a neutral line and an earth line.
▶
Strip the voltage supply line by approximately 80 mm.
Shorten all of the conductors, except for PE, to 60 mm.
Remove the insulation by a maximum of 8 mm. If these
lengths are exceeded, there is a risk of a short circuit.
▶
If the energy supply company requires that the heat
pump is controlled using a blocking signal, also connect
the air/brine collector to the heat pump via the electricity
meter so that a block by the energy supply company can
be switched off for both products at the same time.
▶
Connect the eBUS connection
X3
to the eBUS connec-
tion on the heat pump. Use a ground connection that is
suitable for laying cables underground and that has a
cross-section of at least 2 x 1.5 mm
²
.
Conditions
: Installing two air/brine collectors
▶
Place a junction box close to the heat pump and connect
the eBUS lines to this.
▶
Set the eBUS address switch for the first air/brine col-
lector to 1 and the eBUS address switch for the second
air/brine collector to 2.
5.9.4
Circuit breaker for the air/brine collector
A circuit breaker is used to secure the air/brine collector
against short circuits. If the circuit breaker has been
triggered, the air/brine collector remains switched off until the
short circuit has been rectified and the circuit breaker in the
connection box has been manually reset.
The fault message
F.708
or
F.782
is shown in the heat pump
display.
5.9.5
Resetting the circuit breaker for the
air/brine collector
1.
Check the supply line to the mains connection PCB in
the air/brine collector's electronics box.
2.
Check that the air/brine collector's mains connection
PCB is working correctly.
3.
Check the supply lines for the air/brine collector.
4.
Check that the de-icer is working correctly.
5.
Rectify the short circuit.
6.
Reset the circuit breaker in the connection box.

1.
Arrange each of the side casing sections
(1)
and
(4)
tilted downwards on the product's frame
(2)
and, in do-
ing so, let the nipples clip into place in the cut-outs that
are provided for this.
2.
Move the side casing sections to the correct, vertical
position.
3.
Screw each of the side casing sections tightly to the
frame using two screws
(3)
.
4.
When installing the retaining bracket, you must observe
the installation location as shown in the illustration.
5.
Secure each of the retaining brackets to the cover using
two self-cutting screws.
6.
Place the cover on the product.
