ABOUT YOUR WATER HEATER
WARNING
This water heater is not intended to be operated, adjusted or tampered with by young children or infirm
persons. Young children should be supervised to ensure they do not interfere with the water heater.
The removal of the front cover will expose 240 V wiring. It must only be removed by an authorised or
qualified 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 flow through the pipe work from the solar collectors to the solar storage tank.
SAFETY
This water heater is supplied with a thermostat, an over-temperature cut-out, and a combination
temperature pressure relief valve. These devices must not be tampered with or removed. The water
heater must not be operated unless each of these devices is fitted and is in working order.
If the power supply cord or plug to the solar control unit or the electrical conduit to the solar storage
tank is damaged, it must be replaced by an authorised person in order to avoid a hazard. The power
supply cord and plug must be replaced with a genuine replacement part available from Solahart. Phone
your nearest Solahart Dealer to arrange for an inspection.
The warranty can become void if relief valves or other safety devices are tampered with or if the
installation is not in accordance with these instructions.
TO TURN OFF THE WATER HEATER
If you plan to be away from home for a few nights, we suggest you leave the water heater switched on.
If it is necessary to turn off the water heater:
• Switch off the electrical supply at the isolating switch to the solar storage tank.
• Switch off the electrical supply at the power outlet to the solar control unit (refer to note below).
• Close the cold water isolation valve at the inlet to the water heater.
Note: If there is a risk of freezing conditions, the electrical supply to the solar control unit should not be
switched off unless the solar collectors are drained, otherwise damage could result (refer to
“Freeze
Protection”
on page 8).
TO TURN ON THE WATER HEATER
• Open the cold water isolation valve fully at the inlet to the water heater.
• If the solar collectors and solar hot and solar cold pipes have been drained, it will be necessary to
bleed the collector circuit (refer to
“Bleeding the Solar Collectors” on page 8).
If the electrical supply to the water heater has been switched off:
• Switch on the electrical supply at the power outlet to the solar control unit. The power outlet must
be switched on for the solar control unit to operate and solar gain to be achieved.
• Switch on the electrical supply at the isolating switch to the solar storage tank.
