De-Stratifi cation
If your installation has been equipped with a de-strati-
fi cation pump wired from the heater, a pump symbol
will show on the display when it is running.
Other symbols
If the wrong buttons are pressed it is possible that an
engineering mode might be accidentally entered and
different symbols will be displayed. In this instance, do
not press any buttons for at least 60 seconds and the
control will revert back to a normal display.
Anti Legionella - Default Off
Th e heater has the option to automatically run a high
temperature Anti-Legionella programme. Th e period
between these runs and the temperature can be se-
lected by the commissioning engineer.
Frost Protection
Th is Heater is provided with frost protection and will
run if the temperature of the water in the tank drops
below 6°C and run until it is 16°C. It uses the de-
Stratifi cation pump if fi tted. Note: Th e heater must be
connected to gas and mains electricity for this function
to operate.
Cleaning
Th e casing is fi nished with a painted epoxy paint
and will mark if abrasive cleaners are used. It should
be cleaned using standard non-abrasive proprietary
products.
Service & Maintenance
It is a mandatory requirement that any gas work
carried out must be by a registered engineer with an
appropriate accreditation.
It is recommended that the Heater is serviced at
least every twelve months.
