Figure 5 Topping up The Tank
NOTE:
The owner should operate the easing lever on the valve once every six months. When the lever is lifted, you should
hear the sound of water spilling into the tank. Hold the lever up until water runs out of the overflow pipe. Gently let the handle
down on the valve, as suddenly releasing may damage the valve seat.
It is a good idea to do this check every time you receive
your electricity bill.
In areas where there is a high incidence of water deposits the temperature and pressure relief valve should
be checked for performance or replaced at intervals not exceeding 5 years or more frequently.
§
OVERFLOW OUTLET AND VENT PIPE
It is important that the overflow outlet and vent pipe are free from blockages and restrictions. If the
overflow outlet is connected to a pipe, regularly make sure that it has not been crushed or kinked. In
most cases the vent pipe should not be connected to any pipe work. If both of these fittings are
blocked, the tank may build up pressure and cause damage or injury. The overflow pipe must be
installed to meet local plumbing codes.
SAFETY WARNING
This water heater is supplied with tempering valve, thermostat and a pressure relief and non-return
valve. These devices must not be tampered with or removed. The water heater must not be operated
unless both of these devices are fitted and are in working order.
The
WARRANTY
can become void if relief valve or thermostat is tampered with or
if the installation is not in accordance with these instructions.
§
SOLAR COLLECTOR GLASS
Ensure the glass on your solar collectors is free of dust, salt spray or any other matter, which may
reduce the effectiveness of the solar collectors. Hose or wash the collector glass with water and a soft
brush when the solar collectors are cool. Outdoor window cleaning products work well on the
collector glass, and may be used to clean the collectors from the ground. Regularly trim any trees that
may shade the solar collectors.

DRAINING THE WATER HEATER
SAFETY WARNING
:
Before draining the system ensure you will not be scalded by the hot
water in the system. (Water temperatures are likely to be well above 50 deg C.)
•
Switch off the electrical supply at the isolating switch to the solar storage tank and at the
power outlet for the solar control unit.
•
Unscrew the water heater drain fitting, sliding the temperature probe out until water flows
freely.
•
If it is necessary to run the water away from the heater (eg. if the tank is indoors), the wires to
the temperature probe can be unscrewed from the controller circuit, and reconnected later,
allowed the probe to be removed from the drain fitting.
•
Ensure the heater is refilled with water before reconnecting electrical power.

WATER SUPPLIES ANALYSIS
Your SolarPower solar water heater is manufactured to suit the water conditions of most Australian
metropolitan supplies. However, there are some known water supplies which can have detrimental
