IMPORTANT
If a water softener system is used in the domestic cold
water inlet piping into the tank, the water treatment
system should be inspected (serviced) at the same time.
If a drinking water filter is used in the main line, the
filter cartridge should also be investigated. All external
equipment must be serviced regularly and function
properly.
Inspection and (if necessary) cleaning of tank must take
place within 2 years of initial start-up and as required
thereafter. Reinspection time must not exceed 2 years.
The internal cleaning of the domestic hot water tank
including its potable water connections may only be
performed by a licensed professional heating contractor.
There are no user serviceable parts on this equipment.
Clean tank enclosure with a commercially available
alcohol-based glass cleaning agent and a soft clean cloth.
CAUTION
Never use a metal brush to clean tank interior or heat
exchanger - only plastic material may be used.

Inspection and (if necessary) cleaning of tank must take
place within 2 years of initial start-up and as required
thereafter.
In the event that the building is unoccupied and not heated
and the danger of frost within the structure exists, the
tank as well as the heat exchanger coil must be drained.
In case the heating system is filled with an antifreeze
(which must be of non-toxic composition), only the tank
must be drained of domestic water and all valves in the
domestic hot water and domestic cold water
piping except for the main fill valve must remain open.
Ensure the DHW recirculation pump is deactivated
(if applicable).
