INSTALLATION – SOLAR STORAGE TANK
THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING.
The system is suitable for installation with Solahart ‘J’, ‘KF’, ‘LC’, ‘LCS’ or ‘BT’ solar collectors.
The solar circuit must be installed with a continuous fall of a minimum 5° in the pipe work from the solar
collectors to the solar storage tank, the solar hot and solar cold pipes must be fully insulated with closed
cell polymer insulation (minimum thickness 13 mm) and the system charged with correctly mixed closed
circuit fluid to offer protection against freeze damage. The system has NO WARRANTY for freeze
damage if there is not a continuous fall in the solar hot and solar cold pipes or they are uninsulated or
the closed circuit fluid has been incorrectly mixed (refer to
“Warranty Exclusions”
on page 53 and to
“Warning: Plumber Be Aware”
on page 25). Thicker insulation may be required to comply with the
requirements of AS/NZS 3500.4.
SOLAR WATER HEATER STORAGE TANK LOCATION
The solar storage tank is suitable for either outdoor or indoor installation. The solar storage tank should
be installed close to the most frequently used outlet and its position chosen with safety and service in
mind.
Consideration must also be given to the position of the solar storage tank in relation to the solar
collectors. There are limitations on both the maximum length of the solar hot and solar cold pipes and
the maximum height between the solar storage tank and the solar collectors. Refer to
“Solar Collector
Location”
on page 22 and to
“Pipe Lengths”
on page 23.
Clearance must be allowed for servicing of the solar
storage tank. The solar storage tank must be
accessible without the use of a ladder or scaffold. Make
sure the temperature pressure relief valve lever is
accessible and the front covers can be removed for
service.
You must be able to read the information on the rating
plate. If possible leave headroom of one water heater
length so the anode can be inspected or replaced.
Remember you may have to remove the entire solar
storage tank later for servicing.
The installation must comply with these installation
instructions and with the requirements of
AS/NZS 3500.4, AS/NZS 3000 and all local codes and
regulatory authority requirements. In New Zealand, the
installation must conform with the New Zealand
Building Code.
The water heater must not be installed in an area with a corrosive atmosphere where chemicals are
stored or where aerosol propellants are released. Remember the air may be safe to breathe, but when
it goes through a flame, chemical changes take place which may attack the water heater.
It is recommended the solar storage tank be installed at ground or floor level and must stand vertically
upright. Remember all local authorities have regulations about putting water heaters into roof spaces.
Note:
It is important for the solar storage tank to be orientated vertically upright in order for the falling
film of closed circuit fluid to operate efficiently.
The top of the solar storage tank must be a minimum of 500 mm below the bottom of the solar
collectors for the system to operate correctly.
