Introduction
Please note that the installation manual states that the
water heater must not be installed in a location where it
may be exposed to freezing temperatures. If the heater
must be left in a space that is likely to experience
freezing temperatures, all water must be drained from
the heater.
Freeze damage is not covered under the warranty.
Use of agents like anti-freeze are not
allowed as they may cause damage to the
water heater's internal components.
Draining the heater
Due to the shape of the heat exchangers and connecting
pipe, it is extremely difficult to get all of the water out of
the heater. Follow the procedure below to best minimize
the chance of freezing:
B Disconnect electric supply.
B Disconnect cold and hot water pipes from fittings on
bottom of heater. Allow water to drain out (have a
catch basin ready).
B After allowing all water to drain out, the heater should
be blown out with low pressure compressed air to
remove as much water as possible from water heater
modules. Bursts of air work better than continuous
flow.
Remember, these suggestions are only made to help
minimize the potential for freeze damage and are not to
be construed as the guaranteed method for dealing with
freeze possibilities.
