Maintenance
The safety valve must be inspected regularly (about 4
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,
the safety valve is defective and must be changed.
The safety valve sometimes releases a little water after
hot water has been used. This discharge is caused by the
expansion of cold water entering the water heater, res-
ulting in a pressure increase, whereby the safety valve
opens.
Emptying
1. Turn off the power to the water heater.
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.
Dealing with malfunctions
If the water fails to heat up, check the fuses in the elec-
trical distribution unit. If none of the fuses have blown,
the problem may be that the temperature limiter has
tripped as a result of a fault in the water heater. Once
the fault has been remedied, the temperature limiter
can be reset. This must be done under the supervision
of a qualified electrician.
Service
When a service is necessary, contact the main contractor.
You must always state the installation date and manu-
facturing number (PF3) .
Only spare parts supplied by NIBE AB in Markaryd may
