▪ An external circulation pump is required and needs to be
controlled by the external thermostat.
▪ A non-return valve must prevent backflow to the inlet of the
passive cooling loop and force the brine to go through the
borehole.
Configuration
None.
5.9
Setting up the brine low pressure
switch
Depending on the applicable legislation, you might have to install a
brine low pressure switch (field supply).
The brine low pressure switch can be used to notify the user when
there is a leak in the brine circuit. The switch (normally closed) is
triggered when the pressure in the brine circuit is lower than the
threshold value of the switch.
NOTICE
Mechanical. We recommend to use a mechanical brine
low pressure switch. If an electrical brine low pressure
switch is used, capacitive currents might disturb the flow
switch operation causing an error on the unit.
NOTICE
Before disconnecting. If you want to remove or
disconnect the brine low pressure switch, first set [C‑0B]=0
(brine low pressure switch not installed). If not, this causes
an error.
If [C-0B]=1 (brine low pressure switch installed), and the brine low
pressure switch is triggered, then:
Heat pump operation
Emergency mode

Unit installation
6.1
Preparing the installation site
Do NOT install the unit in places often used as work place. In case
of construction works (e.g. grinding works) where a lot of dust is
created, the unit MUST be covered.
Choose an installation location with sufficient space for carrying the
unit in and out of the site.
WARNING
The appliance shall be stored in a room without
continuously operating ignition sources (example: open
flames, an operating gas appliance or an operating electric
heater).
6.1.1
Installation site requirements of the
indoor unit
INFORMATION
Also read the precautions and requirements in the
"General safety precautions" chapter.
▪ Mind the following spacing installation guidelines:
≥500
≥600
INFORMATION
If you have limited installation space and need to install the
option kit EKGSPOWCAB (= power cable for split power
supply), remove the left side panel before installing the unit
in its final position. See
unit" [ 4 24].
