direction and some water allowed to
escape. Be aware that this water may be at
a high temperature. Before opening the
valve make sure you are well clear and be
advised that the geyser will be under
pressure so water may be expelled at a
high rate. Guard carefully against exposure
to the water whether through direct contact
or through back splash. Be careful not to
confuse the TP valve with the solar relief
valve fitted on some indirect systems.
Please contact your installer for advice if
unsure.
If at any point the temperature at point of
use (e.g. bathroom) appears to be
increasing or decreasing, the temperature
mixing valve may need to be set or
adjusted accordingly.
Warning
When inspecting your system please bear the
following in mind:
The removal of the electrical cover plate on the
solar geyser will expose 220 V wiring. It must
only be removed by an authorised electrician or
service person.
Care should be taken not to touch the pipe work
connecting the solar storage tank and the solar
collectors. Very high temperature hot water can
be generated by the solar collectors under certain
conditions, and will flow through the pipe work
from the solar collectors to the solar storage tank.
Working at heights should only be undertaken by
suitably qualified personnel, using the proper
safety equipment.
Failure to observe safe
practices may result
in:
scalding / burns;
electrical shock;
and/or falling,
which can cause
serious injury or
death.

Troubleshooting
Should your system not provide hot water please
check the following before requesting a service
call:
Shading from trees is not excessive and is
not covering the collectors for all or part of
the day.
Hot water usage has not been excessive.
Hot water is not leaking from within the
plumbing system that feeds hot water to
the points of use.
The time clock/cntroller is operational and
has been programmed correctly.
The electric meter and/or display light on
the time clock speeds up when the time
clock is active.
Power has been provided to the main board
(i.e. no electrical faults or load shedding).
The ripple relay has not become jammed in
the open position.
The water supply to the home has not been
interrupted (i.e. municipal shut-off)
Please contact your local dealer and/or installer if
all of the above have been checked and there is
still no hot water. A charge out fee may apply if
the system is found to be functioning correctly
and the matter relates to one of the above issues.
