SPARE PARTS
See insert sheet for a list of part numbers.
USER INSTRUCTIONS
Your stainless system is automatic in normal use and requires
only annual servicing, normally this is timed to coincide with
the annual boiler or heat pump service. You should employ
a competent installer to perform the annual service and
complete the benchmark log to maintain your 25-year/10-year
guarantee on the inner vessel.
If water is flowing from the safety valves through the
tundish, this indicates a fault in your heating system and
action is needed.
If this water is hot, turn the boiler/heat pump and/or the
immersion heater off. Do not turn off the water until the
discharge runs cool. The discharge may also stop.
Call out a competent installer to diagnose the fault.
Tell them you have a fault on your hot water system and that
the system includes an unvented hot water cylinder.
AFTER DRAINING
Important:
After draining the cylinder, the hot tap must be
left fully open until the cylinder has fully cooled, failure to
follow this instruction may result in damage to the cylinder &
will invalidate the guarantee.
The installer must follow the Benchmark code of practice for
the Benchmark certification to be valid. Please see page 2
and the Guarantee terms and conditions on pages 27-28 for
further details.
