6. Commissioning
6.1. Commissioning information
Before starting up the TERRA HGL heat pump, the
heating side and the brine or ground water circuit side
must be checked for tightness, rinsed thoroughly,
fi lled and bled carefully.
Commissioning requirements :
- The heating and any storage tank must be fi lled and
bled.
- In the case of brine circuit heat pumps the brine
circuit must be fi lled with antifreeze (-15°C), rinsed
and bled.
- The expansion vessel on the brine side must also
be fi lled.
- The electrical installation must be completed and
fuse-protected in line with legal requirements.
- The heat pump may only be switched on if it is fi lled
on the cold side and on the heating side, and if the
electrical connections have been checked.
- During start-up, the fl ow temperature limit must also
be set. The switch-off point 55°C (for refrigerant
R 407 C) or 65°C (for refrigerant R134A) must be
checked and, if necessary, the set switch-off tem-
perature changed.
- The heat pump is equipped with a start-up delay.
- If the heat pump is to be drained on the heating side
for frost protection, the connection hose on the heat
pump return must be unfastened.
- In the case of ground water heat pumps, the ground
water outlet alarm during start-up must be set in
such a way that shutdown is carried out at a water
return temperature of 3°C.
6.1.1. Selection of the Heat Source Pump
After actuation of the main switch on the heat pump,
the start-up Wizard is started after selecting the lan-
guage. In the start menu of the start-up Wizard, the
heat source pump for rinsing and bleeding the brine
or ground water circuit can be selected manually via
the Navigator Control.
6.2. Operation
The Terra heat pump is switched on and off automati-
cally via a fully-automated Navigator Control system.
For operation and start-up, please refer to the sepa-
rate operation and start-up instructions.
Annual inspection and maintenance of the system by
customer services is recommended, in particular with
regard to the preserving warranty claims.
6.3. Faults
The TERRA heat pump is fi tted with various safety
devices to ensure that no damage can be caused to
the equipment in the event of faults.
If, contrary to expectations, the heat pump does not
work on any occasion, check the error message on
the display of the Navigator Control.
For more information, please see the Navigator Con-
trol operating instructions.
If an error occurs several times in succes-
sion, please contact your IDM Customer
