Filling
Fill the water heater as follows
1. Open a hot water tap in the system.
2. Open the shut-off valve on the incoming cold water.
This valve should then be fully open during opera-
tion.
3. The hot water tap can only be shut off when the
water heater is filled, which is when only water
comes out of the tap (initially an air-water mixture
comes out of the tap).
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 then 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 the cold water taken into the water
heater, resulting in a pressure increase, whereby the
safety valve opens.
Emptying
1.
Turn off the power to the heater.
2.
Shutoff the incoming cold water.
3.
Open the drain valve.
During draining air must be let into the heater by loos-
ening a hot water heater connector or a hot water tap.
When mounted in locations exposed to the risk of frost,
the hot water heater must be emptied whenever not in
operation. Freezing will result in the heater bursting.
Dealing with malfunctions
If the water fails to heat up, check the fuses in the
distribution box. If none of the fuses have blown, the
reason may be that the temperature limiter has tripped
as a result of a fault in the hot 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 servicing is required, contact the main contrac-
tor; you will always need to provide the manufacturing
number (95) and installation date.
Only spare parts supplied by NIBE AB in Markaryd may
be used.
