Circulation Pump Position
The circulation pump should be pipe mounted in a
position that is sheltered from direct exposure to the
sun and weather.
The pump cover should be fitted over the pump to
prevent water coming in contact with the electrical cover.
The circulation pump must be mounted with the motor
shaft horizontal and cable gland below the pump as
shown in Figure 27.
Please refer to the manufacturer’s instructions for the
circulation pump installation details.
INSTALLATION OF CIRCULATION PUMP
Failure to follow the manufacturer’s instructions may
cause failure of the circulation pump and will void the
warranty.
The power lead for the circulation pump is connected to
the electronic controller.
Please refer to the manufacturer’s instructions for the
electronic controller for wiring connection details.
The system installation diagrams shown in Figure 29 and
Figure 30 show the general arrangement of components,
plumbing and wiring.
INSTALLATION OF GAS BOOSTED STORAGE TANK
Regulations & OH&S
Before starting installation of the hot water storage
tank and gas booster, the installer should ensure they
have read the “Important Information” section of these
instructions and are familiar with the relevant standards,
OH&S regulations and safety precautions listed.
Hot Water Storage Tank Location
The hot water storage tank should be located as close as
possible to the most frequently used hot water outlets
to minimise water wastage and heat loss. Also consider
that the solar collectors should be mounted as close as
possible to the hot water storage tank to minimise pipe
runs and heat loss.
The hot water storage tank has an ingress protection
rating of IPX4 and is suitable for internal or external
installation.
For external installation, the hot water storage tank
should be mounted on a concrete base at least 50 mm
thick in accordance with AS/NZS 3500.4 clause 4.5.3, or
on well seasoned, evenly spread hardwood slats at least
25mm thick.
For internal installations, or where water leakage may
cause property damage, the hot water storage tank should
be installed with an approved safe tray in accordance with
AS/NZS 3500.4 clause 4.4. This will prevent property
damage in the event of a leak and will allow draining of
the hot water storage tank for maintenance.
Ensure the hot water storage tank does not stand on wet
surfaces.
The gas boosted hot water storage tank will require a
cold water supply as outlined in the “Water Supply”
section in this section of these instructions.
All system components must be located for accessibility.
The hot water storage tank must be accessible without
ladders or scaffolding. Clearance must be provided for
access to and removal of all serviceable parts including
P&TR valve, circulating pump and gas booster (where
fitted to tank).
Warning signs and information on rating plates must be
visible.
