ABOUT YOUR WATER HEATER
8
MAINS PRESSURE
The water heater is designed to operate at mains pressure by connecting
directly to the mains water supply. If the mains supply pressure in your area
exceeds that shown on page 23, a pressure limiting valve must be fitted. The
supply pressure should be greater than 350 kPa for true mains pressure
operation to be achieved.
PRECAUTIONS
Where damage to property can occur in the event of the water heater leaking,
the water heater must be installed in a safe tray. Construction, installation and
draining of a safe tray must comply with AS/NZS 3500.4 and all local codes
and regulatory authority requirements.
The water heater must be maintained in accordance with the Owner‟s Guide
and Installation Instructions. Refer to “Regular Care” on page 10 and to “Anode
Inspection and Replacement” on page 15.
If this water heater is to be used where an uninterrupted hot water supply is
necessary for your application or business you should ensure that you have
back up redundancy within the hot water system design. This should ensure
the continuity of hot water supply in the event that this water heater were to
become inoperable for any reason. We recommend you seek advice from your
plumber or specifier about your needs and building back up redundancy into
your hot water supply system.
