TEMPERATURE ADJUSTMENT
The water heater features tradesperson adjustable thermostats. They require a licensed electrical worker to
make any temperature adjustments. We advise the thermostats are adjusted to the lowest temperature setting
that meets your needs, especially if there are young children or elderly people in the premises. Refer to
Water Increases the Risk of Scald Injury"
PRECAUTIONS
Under certain installation conditions where damage to property can occur in the event of the water heater
leaking AS/NZS 3500.4 requires the water heater 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. In New Zealand the safe tray must also meet the requirements of Clause G12 of the New
Zealand Building Code. AS/NZS 3500.4 and the NZBC also have particular requirements when a safe tray
must be installed. Alternatively, where additional leak protection is required for installations not defined by
AS/NZS 3500.4, a suitable bund may be constructed to surround the water heater in lieu of using a safe tray.
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.
