Installation – storage tank
and solar controller
20mm thermal
insulation around pipe
The storage tank “ow” connection is to be piped to the
inlet of the collector array. The outlet of the collector array is
to be piped to the “return” connection on the storage tank
and shall have continuous fall back to the storage tank. It
is recommended that the sensor cable be run at the same
time as the collector piping for convenience. Ensure that the
sensor cable is installed neatly, kept out of the way and is not
in contact with any potentially hot surfaces or copper piping.
If the tank is not to be installed until a later date, ensure that
the sensor plug is well protected and waterproofed (e.g. put in
plastic bag and cable tied in a safe location) until nal assembly.

An isolating and not return valve must be installed on the
inlet to the hot water system. If it is possible that the supply
pressure could exceed 600kPa, a pressure limiting valve shall
also be installed on the inlet piping. A pressure relief valve
may also need to be installed on the inlet to the hot water
system under local plumbing requirements.
If the hot water system is installed in a bad water quality
area where regular flushing is required due to sediment
build-up, a drain cock or valve is also to be installed on the
inlet piping.
On the storage tank return connection install a 1/2" copper
union, 1/2" nipple and 3/4" to 1/2" reducing bush with
appropriate thread sealant.

Installation of pipe work between the collectors and
storage tank
The pipe work between the collectors and the hot water
storage tank is to be made of copper and be a minimum of
1/2" in diameter. It shall be covered with 20mm thick thermal
insulation to maintain the efciency of the system, prevent heat
loss and to allow the proper operation of the freeze protection.
Any piping insulation that will be exposed to sunlight must
also be UV resistant. The copper pipes shall be supported by
saddles and installed neatly with no sharp bends. The pipes
shall not exceed the recommended length of 10m (20m total)
and the height difference between the storage tank and the
collectors must not be greater than 9 meters. Penetrations
through the roong material must be neat, kept as small
as practical and made at the high point of the roof tile or
metal sheet. Exposed insulated pipe work between the solar
collectors and the penetration through the roong material
should be kept to a minimum to maintain the aesthetics of the
installation. The penetrations are to be waterproofed upon
installation of the pipe work and a boot shall be installed to
prevent any water from leaking into the premises.
