Nibe F1145 5 - Commissioning and Adjusting; Preparations, Filling, and Venting

Preparations
1.
Check that the switch (SF1) is in position " ".
2.
Check that the temperature limiter FD1 has not
tripped.
3.
Check for water in any hot water heater and climate
system.
Caution
Check the temperature limiter, motor protection
and miniature circuit-breaker. They may have
tripped during transportation.
NOTE
At the time of commissioning, complete all rel-
evant sections of the Benchmark Checklist loc-
ated at the back of this document.
Completion of the Benchmark Checklist is a
condition of warranty. For full terms and condi-
tions of warranty, please see our website

Filling and venting
Filling and venting the climate system
Filling
1.
Open the filling valve (external, not included with the
product). Fill the climate system with water.
2.
Open the venting valve .
3.
When the water that exits the venting valve is not
mixed with air, close the valve. After a while the
pressure starts to rise.
4.
Close the filling valve when the correct pressure is
obtained.
Venting
1.
Bleed the heat pump via a vent valve and the rest of
the climate system via their relevant vent valves.
2.
Keep topping up and venting until all air has been
removed and the pressure is correct.
TIP
If the heating medium pump (GP1) must be run
during venting, it can be started via the start
guide.
Filling and venting the brine system
When filling the brine system, mix the water with anti-
freeze in an open container. The mixture should be pro-
tected against freezing down to about -15 °C. The brine
is filled by connecting a filling pump.
1.
Check the brine system for leakage.
2.
Connect the filling pump and return line on the brine
system's filler connector as illustrated.
3.
If alternative 1 (level vessel) is used, close the valve
under the level vessel (CM2).
4.
Close the three way valve in the filler connector (ac-
cessory).
5.
Open the valves on the filler connector.
6.
Start the filling pump.
7.
Fill until liquid enters the return pipe.
8.
Vent the brine system with venting valve on F1145.
9.
Close the valves on the filler connector.
10.
Open the three way valve in the filler connector.
11.
If alternative 1 (level vessel) is used, open the valve
under the level vessel (CM2).
TIP
If the brine pump (GP2) must be run during
venting, it can be started via the start guide.
