Maintenance
Before carrying out any maintenance please remember to first electrically isolate the equipment and then
hydraulically isolate the equipment.
Please ensure that competent trained engineers are used to carry out any service or maintenance work.
It is recommended that the system as a whole is serviced and inspected annually. At that time the gas charge
within the system expansion vessel (if appropriate) should be checked and verified as equal to the cold fill
pressure set on this pressurisation unit.
The cold fill pressure should be equal to the static height of the 0.3 bar, to ensure air is capable of being
purged from the uppermost points of the system.
The pump, float valve (ball cock) and high / Low switches should also be checked at this interval as a minimum.
Check the internal filters within the break tank are present and clear.
A visual check of the equipment for corrosion or damage should also be carried out and noted. All settings
should be recorded and compared to the previous service or commissioning for analysis of the system as a
whole.
This equipment is designed to provide periodic water top up in the event of minor losses from a sealed heating
or chilled system. Please consider the environment and report / rectify any significant water losses.
