Completely
insulate the
water inlet and
outlet fittings.
Do not cover the
water drain plug
with insulation.
The water in the
pipe can be drained.
Insulate the
water supply
valve completely.
Perform the following insulation measures for
prevention of freezing.
• Take appropriate heat insulation measures (e.g.
wrapping with heat insulation materials, using
heat tape, electric heaters, solenoids, or pipe
covers) according to the climate of the region
to prevent the plumbing external to the Water
Heater from freezing.
The freeze prevention heaters will not prevent
this plumbing from freezing.
• Make sure that there are no water leaks from the
cold and hot water supply lines, then insulate the
pipes completely.
• Be sure to also completely insulate the water
supply valve and the cold and hot water
connections on the Water Heater.

water supply taps, remove the water inlet strainer
located on the cold water supply inlet connection.
Remove any debris from the filter and replace.
When replacing the filter, do not over-tighten the
Sealing.
For any sanitary fixture used for personal
hygiene, the delivered hot water temperature
