For the User
MAINTENANCE
The safety valve in the system where the accumulator tank
is installed must be inspected regularly (about four times a
year) to prevent blockages.
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.
SERVICE
For service, contact the installer. Serial number (PZ3) (14
digits) and installation date should always be stated.
Only replacement parts supplied by NIBE may be used.
