INSTALLATION – STORAGE TANK
COMPLIANCE WITH STANDARDS
The installation must be performed by an Authorised Persons and comply with the requirements of
AS/NZS 3500.4, AS/NZS 3000, and all local codes and regulatory authority requirements. It is
recommended the solar storage tank be installed at ground or floor level. The water heater must stand
vertically upright.
SUITABILITY FOR INSTALLATION IN FROST AREAS
The system is suitable for installation in areas that experience sub-zero temperatures, it has an air bleed
valve freeze protection system integrated into the system to prevent damage in the event of a light
frost. Areas of known heavy frost or altitudes higher than 600 m above sea level are not suitable for
this system.
NOTE: THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING.
LOCATION
Whether located outdoor or indoor, the solar water heater storage tank should be installed close to the
most frequently used hot water outlet (typically the shower) and its position chosen with safety and
service in mind. The panels should be located as close as possible to the storage tank.
CLEARANCES
Allow adequate room to work with tools. A minimum of 25mm clearance around the water heater is
required. An additional 30mm is required for relief valve removal, 80mm for access cover removal and
400mm for element removal. You should be able to read the information on the rating plate and all
informative labelling.
Adequate provision must be made to dispose of any water escaping from heater or adjacent plumbing
that might result in damage to property.
The water heater must be connected in such a way that:
•
both the electrical covers are accessible to a service agent.
•
space is allowed for the removal of the heating element.
•
the pump is accessible for servicing.
•
or complete removal of the unit if necessary.
CONFINED SPACES
If the thermostat fails the unit may produce excessive steam.
It is strongly recommended that the heater should be installed in a well-ventilated space to avoid
condensation build up.
If installed in confined areas, make provision for Service Access.
Vent safely to open air and carry hot water overflow pipework to drain.
FOUNDATION
To ensure adequate ventilation, position the unit on an approved support base on a concrete slab (See
figure below).
