Expansion vessel check and re-charging
Check pressure via the Schrader valve on top of the vessel which
is situated under the removable plastic cap. The vessel can be
checked and recharged by switching off the stopcock or isolating
the water supply to the cylinder, then opening a hot tap to deplete
the pressure inside the cylinder. Unscrew the black plastic cap on
the expansion vessel to reveal the Schrader valve, with the aid of a
pressure gauge ensure the pressure reads 3.0 bar. If there is insuf-
ficient pressure within the vessel, top up the vessel via a pump and
recharge to 3.0 bar.
Safety valves
If all previous checks have been done and water is still being dis-
charged from either safety valve, determined which valve is faulty
and replace one supplied by Mixergy.
Cross flow
If all the valves have been replaced and the vessel re commis-
sioned then the system could be suffering from cross flow, this
is when the hot and cold systems are not balanced and higher
pressure cold water is forced back into the cylinder. If this is the
case then an additional pressure reducing valve may be required
to reduce the cold water supply.
Immersion heaters
If the immersion heater is not heating the water adequately it has
either failed (in which case a replacement immersion heater as
supplied by Mixergy should be fitted), an electrical fault is present
or the electrical cut-out has operated due to the control thermo-
stat being set too high or being faulty. Activate the reset button
under the immersion cover. If the problem persists please contact
Mixergy directly.
