7 FLMO WMS 800 MNOFILLER PRESSURE-REUING VLVE WMS 800 It is particularly recommendable to fit this low-water-level security in heating systems with boilers at the highest point. If the water level is too low, the WMS 800 will switch the burner off. This action prevents the boiler from boiling dry. pressure-reducing valves comprehensive range of valves specially designed for building services applications. oth adjustable (by screw with locking nut) and factory pre-setting is available for all sizes ( 1 /2 2 ). Integral stainless steel strainers are fitted and all larger valves have a pressure gauge with union. The gauge may be mounted on either side. Maximum inlet pressure 16 bar.

The filling and draining cock can be opened and closed by using the rear of the shut-off cap. T-piece with 1 /2 coupling. MNOFILLER Manofiller filling group The Manofiller filling group is suitable for fitting to one of the loose connection points of a radiator. The best use for a Manofiller is in situations in which the pressure gauge is fitted to or next to the boiler/cooling machine, while the system is filled somewhere else: perhaps in the bathroom. It is possible to fit it in any position. : flexible with useful accessories! 7

However, for a better solution, you can turn to the Flexfast isolating union, Flexconsoles or Flexcon connection sets shown here. Their use greatly facilitates reading the pressure or disconnecting the vessel without draining the system or releasing the pressure. ISOLTING UNION. ONNETION SETS. FLEXFST 3 / 4 Valve open Valve closed The Flexfast isolating union makes it possible to inspect the pre-pressure of Flexcon vessels with capacity of up to 25 litres quickly and efficiently, or to replace the vessel without the system losing pressure or having to be drained.

PRESSURE SFETY FLEXON ISSSEMLY SPNNER T FLMO FUNNEL FLEXON M 2 VESSEL SUPPORT Together with each Prescor valve belongs a funnel The funnel keeps the connection open to the atmosphere under all conditions; if there is a blockage or if the supply pipe is frozen, an open connection is vital to safety. funnels can be rotated in relation to the elbow joint, which means that they can be mounted easily. Installation The Flexcon T disassembly spanner easily unscrews a stuck Flexcon vessel. Flexcon vessels have a long service life. When they, eventually, have to be replaced, they may be so tight that it seems impossible to remove them. Help is at hand, in the shape of the Flexcon disassembly spanner - the best way to release such Flexcon vessels. Flexcon ombi-set TThe Flexcon ombi-set is a universal connection set for expansion vessels. They can be used if a Flexcon vessel cannot be fitted directly to an existing system, for example if expansion vessels have to be changed. The set has a flexible pipe ( 3 /4 x 3 /4 ) of length 520 mm. Pressure-safety System high or low pressure cut out switch. Safety device for wiring into boiler controls. One switch for each operation. Flexcon M 2 vessel support 1. The Flexcon M 2 vessel support is fitted to the wall with the threaded dowel pins and plugs supplied. 2. The Flexcon M 2 has a slot in which the vessel's clamp fits exactly. The action of screwing in the two pins clamps the tank in place. 3. The Flexcon M 2 is suitable for fixing Flexcon and irfix vessels with capacities of up to 25 litres to the wall. 10

11 Prescor, Flopress, Prescomano and PrescorPlus Should the pressure in the installation rise too high, the Prescor safety valve will ensure that the excess water and steam are discharged safely. Prescor safety valves for sealed central heating and chilled water (cooling) systems. Pre-set pressure, non adjustable, membrane seal, quick release. The Prescomano is a combination of a Prescor safety valve and a Flexcon pressure gauge.

12 Prescor S safety valves and full-stroke safety valves with flanges Prescor S safety valves are suitable for sealed central heating systems with outputs of up to 1980 kw at 3.0 bar. Unnecessary use of the safety valve must be avoided as otherwise there is a greater risk that dirt will build up between the valve and its seat. Full-stroke safety valves with flanges are TR approved. Full-stroke safety valves with flanges must also be fitted vertically, in accordance with local rules and regulations.

13 Manofiller, pressure-reducing valves and (thermo)pressure gauges ecause of its radiator coupling, the Manofiller can be connected directly to existing radiator connections. Flexcon pressure gauges must be mounted using a suitable llen key. In the case of the Flexcon thermo-pressure gauge, a hexagonal key is needed. Flexcon Ø 80 pressure gauges and Flexcon thermo-pressure gauges may be fitted and changed without draining the system, due to the shut-off valve. pressure-reducing valves are compact with excellent performance.
