SOLAR COLLECTOR LOCATION
10
WARNING: Plumber
– Be Aware
Plastic pipe
MUST NOT
be used, as it will not withstand the temperature
of the closed circuit fluid generated by the solar collectors under
stagnation conditions. The solar collectors can generate extremely high
closed circuit fluid temperatures of up to 150°C. Plastic pipe cannot
withstand these temperatures and
MUST NOT
be used. Failure of plastic
pipe can lead to the release of high temperature closed circuit fluid and
cause severe water damage and flooding.
Caution:
Do not over tighten fittings as the rubber washer may not seal
properly. Maximum tightening torque is 15 Nm. Tighten fittings by hand
and then add an additional half turn with spanner.
The pressure applied to the solar circuit and solar collectors during a
pressure test of an indirect closed circuit system
MUST NOT
exceed
200 kPa, otherwise damage may result to the solar collectors. Refer to
on page 12.
Upon completion of the installation of the NPT200 solar collectors the
packaging material may be removed, whether or not the solar circuit is
connected to the solar storage tank and / or the solar water heater is
commissioned.
Maximum Number of Collectors
The maximum recommended number of collectors for the tank size are:
160 litre tank
– 2 x NPT200 collector
