Maintenance
Safety valve (not supplied)
The water heater's safety valve sometimes releases a
little water after hot water usage. This is because the
cold water, which enters the water heater, expands when
heated causing the pressure to rise and the safety valve
to open.
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
1. If an immersion heater is installed, disconnect the
power to this.
2. Shut off the incoming cold water.
3. Open the drain connection, or the drain valve (en-
closed) if installed.
During draining, air must be let into the water heater by
loosening a hot water connector (XL4) or opening a hot
water tap.
To ensure that the water heater drains completely, a
hose, or a pipe, with an outlet below the lowest level of
the water heater must be attached to the drain connec-
tion or drain valve. When installed in a location that is
exposed to the risk of frost, the water heater must be
emptied whenever it is not in operation. Freezing will
result in the water heater bursting.
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.
