FROST PROTECTION
The water heater has a frost protection system. The frost protection system will protect the water heater from
damage, by preventing ice forming in the waterways of the water heater, in the event of freezing conditions
occurring.
The frost protection system will be rendered inoperable if electrical power is not available at the water heater.
Damage to the water heater caused by freezing of the pipe work to or from the water heater is not covered
under the Rheem warranty. Refer to AS/NZS 3500.4 for precautions to be taken for installations in frost
prone areas. The water heater is not suitable for installation in areas where the ambient temperature falls
below -20°C (including wind chill factor).
The cold water line to the water heater must be insulated with suitable thickness insulation if freezing
conditions are likely to occur. The insulation must be fitted to the underside of the water heater and be
weatherproof and UV resistant if exposed.
REDUCING HEAT LOSSES
The hot water line from the water heater and the pipe work between the solar storage tank, if one is installed,
and the in-series gas booster must be insulated in accordance with the requirements of AS/NZS 3500.4. The
insulation must be weatherproof and UV resistant if exposed. The insulation must be fitted up to the
connections on the both the underside of the water heater and the solar storage tank.
