Components
Test point
1
Electricity
Field wiring
All switches with contacts with different polarities should be connected se-
curely in accordance with the specified directives or laws.
Cable connections should only by made by trained specialist personnel.
Cable connections and electrical components available separately should
comply with European and local directives.
Cable connections should be made in accordance with the circuit diagram pro-
vided with this unit.
2
Circuit breakers
A circuit breaker (earth leakage breaker) with 30 mA should be installed.
The circuit breaker in the control cabinet of the indoor unit should be switched
on before the unit is commissioned.
3
Earthing
An earthing wire should be connected. Never connect an earthing wire to a gas
pipe, water piping, a metal object of the building, a surge protection or similar.
4
Power supply unit
Use a separate mains cable.
5
Cable connections of the
terminal panel
Connections on the terminal panel (in the control cabinet of the indoor unit)
should be fixed in place securely enough.
6
Water pressure
Fill pressure
After filling with water, the pressure gauge should show a pressure of 1.0 to 1.5
bar. The maximum pressure should not exceed 3.0 bar.
7
Purging
While filling with water, the system should be purged via the purging hole.
If no water comes out after pressing on the tip (on the top side of the opening),
the purging process is not yet complete.
If the system has been purged optimally, water sprays out like a fountain when
pressing on the tip. Take care when testing the purging. Water could spray on
your clothes.
8
Isolating valve
Both isolating valves should be open.
11
Installing the unit
Maintenance of compo-
nents
There should be no visibly damaged components in the indoor unit.
12
Refrigerant leak
Refrigerant leaks reduce the output of the unit. In the event of leaks, please in-
form an authorised after-sales service partner.
13
Electrical components
After completing the work, make sure that all components are properly wired
and that no live parts can be touched after closing the cover. Make sure that
the covers are securely closed.
