• All pipes, pipe fittings, valves and other components, including soldering materials, must be
suitable for potable water systems.
• A manual shut off valve must be installed on the cold water inlet to the water heater between
the main water supply line and the water heater.
• Only a gate valve or a ball valve is to be used on the cold water supply.
• No stop taps or check valves are to be used as this will void the warranty and damage the wa-
ter heater.
• Check the cold water pressure and if above 1000 kPa, an approved pressure limiting valve must
be fitted.
• Before installing the water heater, flush the water line to remove all debris, and after instal-
lation is complete, purge the air from the line. Failure to do so may cause damage to the
heater.
• There is a wire mesh filter to discourage debris from entering your heater. Clean filter after
initial installation to ensure no debris from the pipe work has clogged it.
3. REMOVE BY TURNING
COUNTERCLOCKWISE
AND THEN CLEAN AND
REPLACE
NOTE: This filter must be cleaned as part of regular maintenance.
