6 Product description
The FlexFiller Direct G4 is the most compact, wall-mounted, pressurisation unit in the portfolio. The
function of this pressurisation unit is to provide a means of automated water filling and 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.).
The FlexFiller Direct G4 is the latest in pumpless digital pressurisation technology for light
commercial and residential buildings. It’s a slim, wall-mounted pumpless top-up pressurisation unit,
with a top-up flow rate of up to 14 l/min depending on the mains or boosted mains, water pressure.
It is designed to be connected directly to a building’s incoming water supply using the included
flexible hose. It is there to fill and maintain the pressure of a heating or chilled water system without
the need for a pump.
This equipment is not designed to cope with sudden, substantial, losses of system
pressure (e.g. manual draining) or major water losses (e.g. large leaks). The equipment is
also not intended to be used for water boosting (potable) applications.
6.1 Operating principle
The following schematic shows the internal arrangement of the pressurisation unit:
1. Water enters the unit via the mains connection, isolation valve (IV) and through the back-flow
preventor.
2. Pressure sensors (P1 & P2) monitor the pressure in the mains water supply system and in the
heating or cooling system.
3. A solenoid inlet valve (S1) and a drain valve (S2) are activated when topping up is required.
4. The automatic air-vent (AAV) removes free air before it enters the sealed heating system.
5. Once the top up cycle is finished, the remaining water in the unit is removed by opening of the
drain valve (S2), to prevent legionella build up.
6. A filter on the mains supply to the unit is already installed. Where debris from the supply pipe is
expected, it is recommended to install an additional filter or Y-strainer on the mains water supply to
the unit.

7 Installation requirements
The FlexFiller Direct G4 is a wall mounted unit and should be installed at a suitable eye level, where
the screen is easy to read and maintenance remains practical and possible. The wall of the set-up
location for the FlexFiller Direct G4 must be such that stability is guaranteed and maintained.
For general assembly instructions and commissioning steps of the product, see FlexFiller Direct G4
Quick Start Guide in link below:
https://flamcogroup.com/manuals/flexfiller-direct
All Flamco products should be installed by a Qualified Person with regard to the relevant
requirements described in section 5.4: ''Sta qualification''. Check that the installation and other
actions prior to use have been carried out in full (e.g. power supply available and connected,
functioning or active fuses, seal tightness of the equipment). Any damage or loss incurred through
incorrect commissioning by an unapproved engineer will not be covered by the warranty.
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/
or property.
Conditions
1. This equipment is designed to be installed in an indoor environment. The unit must be
installed in a frost free environment, away from precipitation and water sprays/jets.
2. The heating/cooling system is fitted with an appropriate safety valve and expansion
vessel.
3. Non-return valves, pressure reducing valves and RPZ valves must not be installed between
the pressurisation unit and the heating/cooling system. These devices will prevent the
pressure sensor from reading the system pressure.
4. It is essential to have the pressurisation unit and the associated system expansion vessel
connected to the system at the same point, to provide a neutral pressure reading. This
point of connection should be in the system return header, on the suction side of the
circulation pump.
5. All necessary pipe/electrical connections have been made to a local standard.
6. Refer to the appropriate datasheet for the maximum working pressure and temperature of
the pressurisation unit. The conditions at the point of connection to the system must not
exceed these values.
7. The expansion vessel is pre-charged to the correct pressure (equal toFlexFiller Direct G4
fill set-pressure))
It is advisable to fill the heating/cooling system prior to commissioning. If this is not
possible, the FlexFiller Direct G4 can be used to fill the system aer commissioning.
Depending on the size of the system, this may take a considerable amount of time.
A mains cable is provided with the unit. A mains cable length of 1,5 meter may not be
exceeded if replacement of a cable is necessary.
Two WRAS approved flexible hoses with isolation valves are provided with the unit. It is
essential for the maintenance of this unit to use hoses provided.
