Nibe AMB 30, Installer Manual

Page: 28 / 52

Preparations
Before commissioning, check that the brine circuit is
filled and well vented. Check the pipe system for leaks.
Filling and venting the brine
system
The brine system is filled with liquid to the required
pressure according to the heat pump installation and
maintenance instructions. Vent the system using the
venting nipple at the brine out (XL7) and possibly the
circulation pump.

door air operation
1.
Check that the brine system has been vented.
2.
Turn the isolator switch on.
3.
Check that all incoming phases are powered.
4.
Check that the miniature circuit-breaker (FA1) is
on.
5.
Go into service mode in the control panel (hold the
OK button in for 6 seconds) and select what type
of system (Hybrid or Outdoor air) is installed in the
menu "System type".
6.
Start the heat pump according to the starting in-
structions.
7.
Go to menu 5.1.7 (br pmp al set.) in the heat pump
and change "min. brine out" to -12 °C.
8.
Fill in the installation checks on page 3 and the
installation information in the user handbook.
NOTE
The live external control must be taken into
consideration when connecting.

Readjusting, collector side
Air is initially released from the refrigerant and venting
may be necessary. If bubbling sounds can be heard
from AMB 30, the heat pump, the circulation pumps
and reversing valves will require further venting. When
the system is stable (correct pressure and all air elimin-
ated) the automatic control system can be set as re-
quired.
Adjustment, charge flow
When installing with several AMB 30 the brine flow is
adjusted so that it is evenly divided between the units
with maximum flow.
