Electrical connection work
The following applies to all work to be done:
DANGER!
Risk of fatal electric shock!
All electrical connection work must be
carried out by qualied electricians only.
Before opening the unit, disconnect the
system from the power supply and prevent it
from being switched back on!
DANGER!
During installation and while carrying out
electrical work, comply with the relevant
EN‑, VDE and/or local safety regulations.
Please note and follow the “Electrical Connection Work”
section of the respective heat pump type.
Operating manual for the respective heat pump
type.
Connect cables A and C of the brine pressure limiter, as
shown in the terminal diagram, to the corresponding termi-
nals of the respective heat pump type.

Insulation
Insulate on site in accordance with the relevant local
standards, guidelines and directives.
Insulate the riser pipe with vapour diffusion-proof insulator
along its whole length to prevent condensation.
Glue the abutting surfaces and ends of the insulation to
prevent penetration of condensation,
Setting
The range and difference (Diff) settings are made using the
hexagon screws at the top of the pressure switch. The upper
switching point is determined by adding the difference value
to the lower switching point.

Setting example (recommendation): triggering of the
brine pressure limiter at 0.5 bar = lower switching point.
Required settings:
lower switching point + difference (Diff) = upper switching
point (Range)
0.5 bar + 0.5 bar (Diff) = 1 bar (Range)
Make the setting as follows:
Undo the stop screw.
Pull off the adjusting and locking key.
Make the necessary settings at the upper switching
point (Range) and Difference (Diff).
To x the settings, put on the adjusting and locking key
again and fasten with the stop screw.
