Maintenance
Safety valve
The function of the safety valves must be regularly
checked, about four times a year, to prevent clogging.
To inspect the valve, open the safety valve manually and
check that water flows through the overflow pipe. If this
does not happen then the safety valve is defective and
must be replaced.
Emptying
The water heater
1. Cut the current to the immersion heater and solenoid
valve.
2. Shut off the incoming cold water.
The water heater is emptied through the siphon in the
cold water connection. To provide an air supply, a hot
water tap in the system can be opened and a pipe
coupling on the hot water side can be loosened.
The climate system
1. Cut the current to the immersion heater and solenoid
valve.
2. Shut off the incoming cold water.
Empty the double-jacketed space through the siphon in
the docking connection, exiting to the outer heat source.
The air nipple can be opened to supply air if necessary.
Consideration must be taken to the entire climate system
before the double-jacketed space is emptied.
Service
For service, contact the installer. Serial number (PF3) (14
digits) and installation date should always be stated.
Only replacement parts supplied by NIBE may be used.
NOTE
If immersion heaters are installed, please ensure
that therminal cut-out are also installed.
