6 Commissioning
6.1 Before you switch on
The heat pump has no separate main switch. In
emergencies, the system must be switched off by
means of the specified circuit breakers. The circuit
breakers must be so reachable as to ensure a
switching off at any time.
Attention - danger to life and limb
The initial switching on of the electrical
systems may only take place in the pres-
ence of a suitably trained and certified electrician.
Switch the power supply to the system ON (or
OFF) only when:
•
Nobody can be endangered
•
All heat pump installation work is com-
plete
•
All wiring is completely connected
•
The voltages correspond to the documen-
tation
•
The hydraulic system is filled with water
and
•
the system has been completely bled
The power supply to the compressor may not be
switched on before the refrigerant circuit and the
hydraulics have been filled with the appropriate
medium.
Once all the above conditions have been met, the
control voltage 230V~ (F1 fuse) can be switched
on in order to check the individual functions.
Check carefully all sensors and their values for
plausibility and all hydraulic outlets for correct
function.
Attention:
Operating the heat pump with no, or
too little refrigerant leads to damage to
the appliance. Operating the circulation pumps
with no water in the system leads to destruction
of the pump.

Commissioning must be carried out by Ochsner
Customer Service or a service partner authorised
by Ochsner. The Ochsner commissioning guide-
lines must be adhered to. Operating the system
without a correct commissioning will lead to a for-
feiture of the guarantee and warranty rights.
6.2 Check list for commissioning
Adhere to the following sequence:
1. Check heating system circuit: System-
pressure, expansion vessel function,
bleeding valves, quantity adjustment.
The system installer is to ensure that, at
the
commissioning, the system tempera-
ture/buffer temperature does not exceed
30°C.
2. Check the flow rates! The flow rates at
heat source and heat use systems are
measured by the integrated flow sensors
and monitored. These can be read off
from the display of the OTE-control.
3. for brine/water heat pumps
4. System pressure, frost protection mix-
ture (-12°C), bleeding
5. Check whether all non-return valves are
open
6. Check power supplies and circuit break-
ers
7. Check the electrical connections to the
system components, including all re-
quired safety equipment, according to
the wiring diagram.
8. Switch on 3-phase supply to the heat
pump.
9. Control 3-phase supply and right-hand
rotary field
10. Switch on control voltage supply
11. Relay test on the output terminals
12. Adjust the system according to user re-
quirements and document these
13. Hand over system to operator
6.3 Required on-site personnel:
Electrician, installer and future system supervisor
MUST be present for the system orientation dur-
ing commissioning.
