temperature should be between 5 and 40 degrees centigrade, non-condensating. Operation outside of
these conditions could seriously damage the equipment.
0.2.7 If the equipment were to be stored or taken out of service for a period of time (e.g. 1 week or more), then
we would recommend draining the equipment of all water/liquid (with due regard to any local regulations)
to prevent frost damage to components. When restarting is required we would recommend commissioning
by our authorised service agent.
0.2.8 Ensure the base/foundation/plinth/wall to which the equipment is to be attached has sufficient mass
compared to the equipment, in order to avoid noise/vibration transmission. E.g. the mass of the base should
be at least five times the mass of the equipment.
0.2.9 Ensure the electrical supply is the correct voltage, current, frequency and type for the equipment supplied
and that suitable circuit protection equipment is installed in the supply. Incorrect electrical installation
could be an electric shock/burns/fire hazard.
0.2.10 When accessing the control panel to make electrical connections adopt anti-static procedures e.g. wear
anti-static earthed wristband, to avoid risk of damaging the controller.
0.2.11 All products that are packaged to include Pressure vessel(s)/Hydraulic Accumulator(s)/Expansion Vessel(s)
are classed as “Assemblies” under the Pressure Equipment Directive (PED). Where units are despatched
with “Loose” vessel(s) for assembly on site it is absolutely essential that they be installed as detailed in the
instructions using the fittings provided where appropriate. Failure to observe this will nullify compliance
with the PED and may present a safety hazard. Your warranty may also be affected.
0.2.12 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/pump overheating could occur.
0.2.13 Do not operate this equipment/pumpset prior to commissioning (section 2.2) This could cause irreparable
damage to equipment/pumpset/pipework/system components.
0.2.14 Isolate the equipment/pumpset before pressure testing system. Excess pressure could irreparably damage
the pressure transducer, pressure switches (where fitted) and the diaphragms of pressure vessel/hydraulic
accumulators.
0.2.15 It is the installers’ responsibility to ensure subsequent pipework etc can accept the pressures generated by
the equipment/pumpset and to install an overpressure safety device into the system with due respect to
the suction pressure present on the pumpset, the pump closed valve pressure stated on the pump, the
maximum working pressure stated on any of the attached pressure vessels and any other device connected
to the system e.g. boilers, calorifiers etc.
0.2.16 When chlorination of the system is carried out, ensure that any residual chlorine is removed by thorough
flushing as detailed in the HSE approved code of practice L8, to avoid damaging the equipment/pumpset.
The normal level of chlorination is up to 2 parts per million (ppm), but shock dosing for sterilization
purposes, at 25-50 ppm for 24-48 hours is acceptable as long as all chlorine is removed once the process is
complete. Chlorination beyond these limits could seriously damage pumpset components and WILL NOT
be covered by the warranty.
0.2.17 The installer/user is responsible for the installation of the correct earthing and protection according to
valid national and local standards. All operations must be carried out by a suitably qualified person.
0.2.18 The equipment is only suitable for earth referenced supplies and must be permanently earthed to avoid
electric shock hazard.
0.2.19 The equipment must be permanently earthed with appropriate sized Earthing.
0.2.20 Equipment containing variable speed drives/motors has high earth leakage current >3.5mA and will require
additional earth bonding whereby a single conductor of increased size or duplicate earth conductors must
be provided.
0.2.21 Never perform high voltage resistance tests on control panels, variable speed drives/motors without first
disconnecting the panel/drive/motor from the circuit being tested as this will damage the built in electronic
components.
0.2.22 Metal parts (e.g. heat sinks) may reach temperatures of 90 degrees centigrade.
0.2.23 EMC - With respect to BS EN61000-3-2 this equipment is defined as ‘professional equipment’ and
therefore the installer/user may need to seek permission from the supply utility to connect this equipment
to the public low voltage mains supply.
0.2.24 It is very strongly advised that the system is pre-filled prior to commissioning. Use of the “Pressurisation
unit” for filling the system pipework, may take considerable time, and in some cases may invalidate the
equipment warranty.
0.2.25 Where “Expansion vessels” are used on LTHW heating system pressurisation units, the temperature of the
fluid returning to the vessels should not exceed 70 degrees Centigrade as this could damage the vessel
diaphragm. Where the temperature exceeds 70C an intermediate cooling vessel should be fitted.
0.2.26 For MTHW and HTHW pressurisation units use a Nitrogen vessel suitable for the system conditions.
