10.3.1 Connecting cold water and DHW
Note
Observe all applicable national and regional regu-
lations and provisions.
»
Install a type-tested safety valve and a non-return
valve on site.
»
Connect the cold water supply.
»
Connect the DHW connection.
»
If necessary, install a pressure reducing valve and a
filter in the supply line as per local guidelines.
»
Make sure that there is a venting possibility (opening
the DHW valve).
Material damage
Before commissioning, the DHW tank must be
completely filled.
The heat pump is equipped with a plate heat exchanger.
The water in the tank can be heated via the plate heat ex-
changer by means of the installed circulation pump.
Fresh water is not permitted to enter via the plate heat
exchanger as it is not designed as an instantaneous water
heater.
10.4 Electrical connection
10.4.1 General
WARNING: Electrocution
Before commencing electrical connection and
installation work, the heat pump system must be
isolated from the power supply.
WARNING: Electrocution
Work on electrical connections and installation may
only be conducted by qualified contractors.
WARNING: Electrocution
Before commissioning, the necessary fault pro-
tection measures on the system and the earth
connection must be checked by a qualified con
-
tractor.
Note
It is essential that the regulations of the responsible
power supply utility (PSU) and the applicable EN
standards are observed.
Note
The values specified in this documentation for
circuit protectors and cable cross-sections are
guideline values.
The qualified contractor carrying
out the work is responsible for plant-specific sizing
of safety devices and cable cross-sections.
OCHSNER does not accept liability for faults resulting from
incorrectly designed safety devices!
We recommend connecting the power supply via its own
RCD. The hot water heat pump is equipped as standard
with a 2 m mains power cable for 220-240 VAC, 50 Hz.
10.4.2 Terminal box
To enable all inputs and outputs to be used, a terminal
box is wired to the appliance. The connection diagram is
located in the lid of the terminal box.
