Installation - Solar Storage Tank - Rheem Loline 271 Owner's Manual And Installation Instructions

INSTALLATION – SOLAR STORAGE TANK
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
"Maximum Height to Collectors"
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 height so the anode
can be inspected or replaced. Remember you may have to
remove the entire solar storage tank later for servicing.
The solar storage tank is to be installed at ground or floor level
and must stand vertically upright on a stable base as acceptable
to local authorities. The base of the water heater is made of
corrosion resistant material, and it may be placed directly in
contact with the supporting surface. It is not necessary to allow
for free air circulation under the base of the water heater.
Note: The water heater should not be placed in direct contact with a concrete surface that is less than two
months old and not fully cured as this may attack the metal coating of the water heater base. A moisture barrier
should be used between the two surfaces in this instance.
Remember all local authorities have regulations about putting water heaters into roof spaces.
SAFE TRAY
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. AS/NZS 3500.4 also has particular requirements
when a safe tray must be installed.
MAINS WATER SUPPLY
Where the mains water supply pressure exceeds that shown in the table, an approved pressure limiting valve
is required and should be fitted as shown in the installation diagram
