INSTALLATION – SOLAR STORAGE TANK
THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING.
SOLAR WATER HEATER STORAGE TANK LOCATION
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
"Solar Collector
the solar storage tank and the solar collectors. Refer to
Location"
"Pipe Lengths"
on page 6 and to
on page 8.
Refer to the installation instructions supplied with the solar storage tank for
installation details of the solar storage tank.
SYSTEM INSTALLATION
INDIRECT CLOSED CIRCUIT SYSTEM INSTALLATION
The system is suitable for installation with NPT200 solar collectors as part of an
indirect closed circuit system installation.
An indirect closed circuit system has a collector circuit which is separate from
the potable water in the solar storage tank. Closed circuit fluid circulates
through and collects heat from the solar collectors before circulating through a
heat exchanger, where the heat is transferred to the potable water of the solar
storage tank.
The system is suitable for installation in areas subject to frost or freeze
conditions. The solar circuit must be installed with a continuous fall of a
minimum 5° (1 in 10 grade) in the pipe work from the solar collector to the solar
storage tank, with the full length of the solar hot and solar cold pipes insulated
and the system charged with correctly mixed closed circuit fluid to offer
"Warning: Plumber Be Aware"
protection against freeze damage. (refer to
on
page 9). Freeze conditions occur below 6°C.
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 not insulated in accordance
with the installation instructions, or the closed circuit fluid has been incorrectly
"Warranty Note"
mixed (refer to
on page 31).
