INSTALLATION – SOLAR STORAGE TANK 
 
THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING. 
 
The system can be installed with Solahart ‘L’ solar collectors. 
 
Although the system has a level of freeze protection, designed to guard the system from unexpected 
frost conditions, the system is not recommended for installation in areas subject to frost or freeze 
conditions. Freeze conditions occur below 6
°C. The solar hot and solar cold pipes must be fully 
insulated with closed cell polymer insulation (minimum thickness 13 mm) to offer protection against 
freeze damage. The system has NO WARRANTY for freeze damage (refer to 
 on 
page 37). 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. Whether located outdoor or 
indoor, 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 the maximum length of the solar hot and solar cold pipes between 
the solar storage tank and the solar collectors. Refer to 
 on page 26 and to 
 
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 cover, thermostat 
and booster heating unit 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 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. 
 
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. 
 
SAFE TRAY 
 
 
It is a requirement of AS/NZS 3500.4 that for a new 
installation, a water heater be installed in a safe tray 
where in the event of a leak, property may otherwise 
be damaged. Construction, installation and draining 
of a safe tray must comply with the above mentioned 
Standard.
