Page 5: About This Manual
About this Manual This Operation and Maintenance Manual contains all the necessary information to install, commission, operate and maintain Flexfiller pressurisation equipment. It is recommended to read all parts of this manual before undertaking any work on the equipment. Conventions used in this Manual This manual makes use of symbols to identify key pieces of information. -
Page 6: Equipment Overview
Equipment Overview The function of this pressurisation unit is to provide a means of automated water top-up to sealed heating and cooling systems. The equipment is designed to provide periodic water top-up to compensate for minor losses in system pressure (e.g. slow leaks, air venting, etc.). This equipment is not designed to cope with sudden losses of system pressure (e.g. -
Page 7: Important Information
IMPORTANT INFORMATION Environment It is not anticipated that this equipment will be exposed to adverse environmental conditions without additional protection. Site the equipment in a frost free area. Ensure that 100 mm of clear access is available around the equipment with 500 mm clear access at the front. -
Page 8: Installation
Installation This pressurisation unit is not designed to be installed in an outdoor environment. The unit must be installed in a frost free environment, away from precipitation and water sprays/jets. If there is a risk of flooding, the unit must be installed on a raised plinth. Please refer to the appropriate datasheet for the maximum working pressure and temperature of the pressurisation unit. -
Page 9: Flow Restrictors
Installation of mini mechanical units Remove the appropriate coverings. Ensure that the float valve is set to its lowest position. All pipework connections are to be made with appropriate proprietary jointing compound. PTFE is not permitted. Connect the overflow pipework. -
Page 10: Flow Restrictors
If no restrictor is required, the filter must be removed from one of the restrictors and installed on its own. The following diagram shows how to remove the filter: To install the flow restrictor/filter, hold it by the tab and push it into the opening of the float valve connection, as shown in the diagram below: Rev 2.1 Oct-15 Page 10 / 28... -

Page 12: Electrical Power Supply
Electrical Power Supply This equipment must be electrically isolated before removing the covers. Cables connected to the volt free contacts may be supplied from another source and may remain live after the unit is isolated. These must be isolated elsewhere. All electrical connections must be carried out by a suitably qualified and competent person. -
Page 13: Commissioning
Commissioning It is highly recommended to have this equipment commissioned by a BOSS approved engineer. Any damage or loss incurred through incorrect commissioning by an unapproved engineer will not be covered by the warranty. Pre-Commissioning Checklist The following conditions must be met before starting the commissioning process. Failure to meet these conditions may result in injury or damage to the equipment, system and property. -
Page 14: Commissioning
Commissioning Commissioning must be carried out by a trained and competent person. Close the system connection valve. (isolation valve) Turn on the unit, the current pump pressure is shown on the mounted gauge. Adjust the pressure (Cold fill pressure) using the pressure switch (black screw) ... - Page 15 To change the pressure gauges turn the screw slightly. Black screw for Range setting Silver screw for Differential (Diff) Pressure setting for switches with automatic reset. 1. Set the cut-in pressure on the “CUT-IN” scale (range scale), 2. Set the differential on the “DIFF” scale. High and Low Pressure Settings (Boiler control) The high pressure switch is pre-set to cut out at 3.0 bar(g) and will not re-set until the system pressure has dropped to 2.0 bar(g).

Page 17: Hydraulic Commissioning
Hydraulic Commissioning 1 – Float Valve Setting Ensure that the break tank float valve is set to its lowest position: Mini Units If a drain valve is fitted to the break tank, ensure that it is closed. Then, turn on the mains water supply and allow the break tank to fill. - Page 18 Turn on the power supply to the pressurisation unit. Depending on the current system pressure, the unit will respond in one of the following ways: If the system pressure is below the low pressure adjust the pressure switch by turning the black screw clockwise.

Page 19: Maintenance
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. -
