Purge the brine circuit
1.
Position a second person at the air/brine collector(s).
Note
The entire purging/filling process should last
at least 30 minutes. During this time, the pur-
ging valves for the air/brine collector(s) must
be opened and closed every five minutes.
We recommend the brine purging support set
for the air/brine collector as this makes the
purging process significantly easier if it is to
be carried out by one person.
2.
Remove the protective caps, which are attached and
transparent in their as-delivered condition, from the
purging valves on the air/brine collector and dispose
of these. These are no longer required.
3.
Open the purging valves
(69)
on the air/brine
collector(s).
4.
Start up the filling pump
(67)
in order to fill and rinse the
brine circuit.
5.
Allow the filling pump
(67)
to run.
6.
Close the purging valves on the air/brine collector(s)
as soon as brine fluid escapes from the purging valves
(69)
.
7.
If required, open all of the other stop valves that are not
shown in the illustrations.
8.
Open and close the purging valves
(69)
on the air/brine
collector(s) every five minutes consistently until air is no
longer escaping.
9.
Open the stop valve
(63)
so that air in the pipeline
between the stop valves
(61)
and
(62)
can escape.
10. Close the stop valve
(61)
.
11. Build up pressure in the system, as described in the
installation instructions for the heat pump.

Electrical installation
Danger!
Risk of death from electric shock caused
by a residual-current circuit breaker.
In certain cases, residual-current circuit
breakers may not work.
▶
If, to ensure that people are protected
properly and fire is prevented, residual-
current circuit breakers are required, use
type A pulse-current-sensitive residual-
current circuit breakers or type B univer-
sal-current-sensitive residual-current cir-
cuit breakers.
▶
Observe the technical connection conditions for connect-
ing to the power supply network operator's low-voltage
network.
▶
Use the values for the maximum rated power that are
specified in the technical data to determine the required
line cross-sections.
▶
In each case, take into consideration the on-site installa-
tion conditions.
▶
Connect the product using a fixed connection and a parti-
tion with a contact opening of at least 3 mm (e.g. fuses or
power switches).
▶
For the electricity supply, connect the product to a three-
phase 400 V AC network with a neutral line and an earth
line.
▶
Fuse this connection using the exact values that are spe-
cified in the technical data.
▶
At lengths of 10 m or more, supply lines must be laid sep-
arately from sensor or bus lines. Minimum clearance for
the extra-low voltage and mains voltage line at a line
length of > 10 m: 25 cm. If this is not possible, use shiel-
ded lines. Lay the shielding on one side of the sheet for
the product's electronics box.
80 mm max.

Insulation
▶
Strip the outer sheathing on the line to the connection
box by approximately 80 mm. Shorten all of the conduct-
ors, except for PE, to 60 mm.
▶
Secure the conductors in the connection terminals.

Max. torque of the connection terminals: 0.5 Nm
