USER INSTRUCTIONS
Your SST Direct storage vessel has been designed to give many years of trouble free service. Where
applicable, it may be fitted with an electric immersion heater which heats the water to 60°C for use as
a back-up should the primary heat source fail for any reason. Note that the hot water supply will be
limited whilst using the immersion heaters.
The flow temperature of the hot water can be set to your requirements on the immersion heater
(ideally 60°C maximum). Higher temperatures can cause tripping of the high limit thermostat and
introduce more energy loss from the cylinder.
When a hot tap is turned on there may be a short surge of water, this is quite normal with unvented
systems and does not mean there is a fault.
When you first fill a basin the water may sometimes appear milky. This is due to very tiny air bubbles in
the water which will clear very quickly.
Warning: If cold/warm water exits from the temperature and pressure relief valve
(TPV) or from the pressure relief valve (PRV) call your installer. If very hot water exits
from either valve switch off the heat source immediately and isolate the electricity
supply to the cylinder and separate heat source.
The solar system is configured to heat the water to its maximum economic
temperature which may vary with ambient temperature and weather conditions. The
immersion may be programmed to operate during fixed periods of the day or night.
If the hot water runs cool it may be necessary to manually switch on the immersion
to heat the water – please see the relevant instructions for your alternative energy
device.
