Maintenance
The safety valve in the system where the accumulator
tank is installed 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.
Emptying
1. Shut off the incoming cold water.
2. Open the drain connection, or the drain valve if fit-
ted.
During draining, air must be let into the accumulator
tank by opening a vent valve or a hot water connection.
To ensure that the accumulator tank drains completely,
a hose or a pipe with an outlet below the lowest level
of the accumulator tank must be attached to the drain
connection or drain valve. When installed where there
is a risk of frost, the accumulator tank must be emptied
whenever it is not in operation. Freezing could result in
the water heater bursting.
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
be used.
