Ensure the Y strainer (100um) and isolation valve is installed on the inlet to the breaktank, failure to
install these will cause the solenoid to jamb and overflow the break tank.
0.2.27
Ensure a pressure reducing valve set at a maximum of 3.0Bar is installed on the inlet to the breaktank
if the mains water supply pressure exceeds 3.0Bar.

CAUTIONS FOR OPERATION/USER
0.3.1
READ GENERAL SAFETY INFORMATION 0.0, WARNINGS 0.1 and CAUTIONS 0.2, 0.3 & 0.4
0.3.2
The unit should only be operated/used by a competent person; A competent person is someone who is
technically competent and familiar with safety practices and the hazards involved.
0.3.3
The Owner/User of this equipment has a Legal Responsibility to ensure that it is subject to regular
formal inspections. See Section 3. Servicing, for details.
0.3.4
Where Hydraulic Accumulator(s)/Expansion Vessel(s) are supplied as a loose item, they must be
installed/connected correctly before operating the equipment, otherwise serious damage from over‐
pressure could occur.
0.3.5
The set must not be run until commissioned, this could irreparably damage the pump set and/or
system components/pipework connected to it.
0.3.6
The pumpset should be left switched ON for normal operation.
0.3.7
Ensure pumpset has an adequate water supply at all times to prevent dry running causing pump seal
damage and water leakage.
0.3.8
Do no attempt to start pumps without liquid in volutes (pumps must be fully primed, see 1.2.2);
mechanical seals must have a film of liquid between faces for proper operation and to prevent
damage.
0.3.9
Minimum flow rate: Due to the risk of overheating, do not use the pump at a flow below the minimum
flow rate. For cold water this is generally 10% of the pump flow rate as displayed on the pump data
plate, on the pump body.
0.3.10
Portable telephones or other electro‐magnetic equipment must not be used near the set to avoid
corruption of program and unpredictable operation of unit.
0.4
CAUTIONS FOR MAINTENANCE
0.4.1
READ GENERAL SAFETY INFORMATION 0.0, WARNINGS 0.1 and CAUTIONS 0.2, 0.3 & 0.4
0.4.2
The unit should only be operated/maintained by a competent person; A competent person is someone
who is technically competent and familiar with safety practices and the hazards involved.
0.4.3
To prevent seizing, pumpsets must not be left unused for long periods (e.g. 1 week).
0.4.4
The pumps must be run regularly to avoid stagnation of water in the pumps/pipework (e.g. daily).
0.4.5
Do not vent air from air valves on vessels. These are for adjustment of pre‐set cushion pressures. If
wrongly adjusted this will lead to incorrect operation of the pumpset and possible damage to pumps,
pipework and system components from overheating and over‐pressure.
0.4.6
Switch OFF pumpset before accessing pumps and/or control panel.
0.4.7
The pump inlet strainer must be periodically cleaned.
0.4.8
The mains water inlet strainer must be periodically cleaned.
