0.2.27
Do not use the “Pressurisation unit” for dosing the system with chemicals. Only allow clean cold water into
the break tank. Anything other than clean cold water could damage the pumps/pipework components.
0.2.28
Drain cocks/valves and air bleed screws must not be left open as this could cause flooding.

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 by an authorised AquaTech-Pressmain agent, 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 with the pumps switched to AUTO for normal operation.
0.3.7
The pumpset should not be left in “Hand” operation for more than 1 minute. This could lead to severe
damage of pumpset components and/or pipework system from over-pressure and/or overheating.
0.3.8
Ensure pumpset has an adequate water supply at all times to prevent dry running causing pump seal
damage and water leakage.
0.3.9
Do no attempt to start pumps without liquid in volutes (pumps must be fully primed); mechanical seals must
have a film of liquid between faces for proper operation and to prevent damage.
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.
0.3.11
For Pressurisation units utilising Nitrogen Vessels (generally HTHW units) ensure there is an adequate
supply of Nitrogen at all times to avoid mis-operation of the equipment.
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
Where the set is fitted with Building Management Services (BMS) interconnections, notify the appropriate
persons before switching OFF for maintenance or adjustments, to avoid unnecessary alarm conditions
occurring. WARNING: With pumpset isolator OFF, mains voltage may still be present from BMS system.
This constitutes an Electric shock hazard.
0.4.4
To prevent seizing, pumpsets must not be left unused for long periods (e.g. 1 week).
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.
