INSTALLATION INSTRUCTIONS
GENERAL
Installation of this water heater must be performed by an Authorised Person and in accordance with
Local Authority Safety regulations, and Electrical and Plumbing Codes applicable in your area. In
Australia, for example, the installation must comply to Australian Standard (AS 3500.4) “National
Plumbing and Drainage Code, Part 4: Hot Water Supply Systems”.
LOCATION SELECTION
Collector Panels
For optimum performance the collector panels should be installed to face the equator (South in the
Northern Hemisphere, North in the Southern Hemisphere)
ALWAYS USE A COMPASS TO CHECK
ORIENTATION
. Deviation from the equator up to 45°East or West has little effect on total annual solar
contribution (approximately 4 per cent). Should it not be possible to face the equator the decision of
either EASTERLY or WESTERLY direction must be made.
(a) If major hot water draw is before 2 p.m. favour EASTERLY
(b) If major hot water draws after 2 p.m. favour WESTERLY.
The westerly direction is more commonly used.
The collector panels should be installed on a roof of pitch or angle that is the same as the latitude angle
of the site. Roof angles within 20° of the latitude angle will have little effect on the total annual solar
contribution (4%). Minimum roof angle is 10º for with-pitch installations.
If it is necessary to face the collector panels 45°East or West of the equator then a flatter (lower pitch)
installation will give better performance. Additional panels facing east or west may be more aesthetically,
economically and thermally beneficial than mounting the Collector Panels on roof brackets to face the
equator.
The collector panels must be installed in an area that is free of shade all year round. Check high trees
and other obstacles for winter shade.
The collector panel location should not be more than 7 metres vertically, for a 10kW POWER
PAK
above
the base of the POWER
PAK
with a maximum pipe run of 16 metres from the POWER
PAK
. For
installations with greater distance than these please consult Solahart for revised pump sizes and
configurations.
POWER
PAK
Module
Select a suitable location near the hot water storage system to which the POWER
PAK
is to be
connected. As the POWER
PAK
is weatherproof, the location may be internal or external. However, in
cold climates an internal location is preferred.
The POWER
PAK
must be positioned such that the electrical socket is accessible.
To minimise heat losses the POWER
PAK
should be located as close as possible to the hot water
storage system and at the same level.
SAFETY
This appliance is not intended for use by young children or infirm persons without
supervision.
Young children should be supervised to ensure that they do not play with the
appliance.
Important
Additional information on installing the pipe work to and from the POWER
PAK
can be
found in Solahart Technical Bulletin #136. This can be obtained from your Solahart
dealer or from Solahart directly.
