WALL BRACKETS
The top of the storage tank is to be secured to the wall (or screen) with the wall brackets provided using
fasteners suitable for the wall type and application.
The fasteners must be capable of bearing the weight of the water
heater so it may neither work loose, pull away from the wall nor
impose any load on the gas and water pipe work connected to the
water heater. Refer to the fastener manufacturer's information and
recommendations for the type of fastener to use for the wall type and
load bearing requirements.
To fit the wall brackets:
•
Position a bracket against the wall on one side and toward the
top of the water heater and mark the fixing points on the wall
where the bracket is to be secured.
•
Repeat this process with the remaining bracket on the other side
of the water heater.
•
Drill holes in the wall to receive suitable fasteners for the wall
brackets.
•
Fix the wall brackets to the wall using suitable fasteners.
•
Secure the bracket to the side of the water heater using the self-
tapping screws provided.
RAINWATER COLLECTION SYSTEM
Before installing a closed circuit system, the installer should determine whether rainwater run-off from the roof
on which the solar collectors will be mounted, is collected in a rainwater tank. If the solar collectors are to be
installed on a section of roof which is part of a rainwater runoff collection system, then it is recommended this
section of roof and its gutter be isolated from the rainwater collection system. The gutter should be isolated to
a width greater than the solar collectors and pipe work and must have suitable drainage. The installer should
ensure in the event of a leak from the closed circuit, a rainwater tank cannot be contaminated with closed
circuit fluid.
The closed circuit fluid acts as an anti-freeze agent and rust inhibitor, is non-toxic to humans and is harmless
to the environment. However it does have an adverse effect on water stored in rainwater tanks. It will kill
microscopic algae typically present in rainwater tanks and cause an unpleasant odour to develop. This will
result in the rainwater tank having to be drained and cleaned.
The section of roof and gutter should be isolated from the rainwater collection system before the commissioning
of the solar water heater, so that any leak or spillage during commissioning does not make its way into the
rainwater tank.
The installer should discuss alternative options to suit the installation with the householder. Any alterations to
the roof drainage system must comply with the relevant building regulations, codes and Standards.
