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
22, 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
on page 9 and to
on page 14.
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.
