The manifold may be used in combination with the thermo-electric actuators to perform diff erent functions:

• fl ow rate regulator: when the pressure changes, due to the opening or closing of some other circuits, the membrane of the bonnet cartridge deforms to alter the cross section of the fl uid passage through the membrane itself and keep the fl ow rate at the preset value, even with high diff erential pressures: up to 60 kPa for the Low Flow version; up to 150 kPa for the High Flow version.
• presetting fl ow rate: the maximum design fl ow rate for each individual circuit may be set and maintained accurately at all times;
• optimising room temperature: the manifold may be used in combination with thermo-electric actuators and thermostats to allow more e ff ective and effi cient temperature control in multiple interior rooms. ­p [kPa] ­p max­p min Q [l/h] Presetted flow rate  Operation R553FP G 100 % G 100 % G 0 % CIRCUITO CHIUSO G 100 % G 100 % G 120 % G 120 % G 120 % R553FP DESIGN LOAD PARTIAL LOAD Radiant system with R553FP manifolds, without dynamic fl ow balancing R553FPDB G 0 % CIRCUITO CHIUSOG 100 % G 100 % G 100 % R553FPDB G 100 % G 100 % G 100 % G 100 % DESIGN LOAD PARTIAL LOAD Radiant system with R553FPDB manifolds, with dynamic fl ow balancing Manifolds with dynamic fl ow balancing are used primarily in radiant systems.

The module assembly/disassembly operations must be carried out only in case of real necessity in order not to risk compromising the hydraulic seal. The manifold is supplied pre-assembled, but new modules can be added or existing ones removed. To disassemble a module, proceed as follows: 1) open the supports with clip connection and remove the manifolds from the brackets; 2) position one of the two R73FPY001 spanners in the front part of the module and the other in the rear part, so that the protrusions “A”, “B” and “C” of the spanners slide into the slots “A”, “B” and “C” on the module; 3) press one spanner at a time against the module to raise the fi ns “C” and rotate the module, so that it can be disassebled from the fi rst side; when doing this, be careful not to lose or damage the O-Ring “D”; 4) repeat steps 2 and 3 to disasseble the second side of the module that needs to be removed; 5) after removing the module, reassemble the manifold: - make sure the O-Ring “D” is correctly inserted on the male fi tting of the module (pushed down as far as it will go), lubricating it with a suitable lubricant for the material (EPDM) and for the intended use of the system (eg. silicone lubricants). During this operation pay attention to lubricate the O-Ring only and not the adjacent plastic parts; - insert the module with the male fi tting in the corresponding female fi tting of the adjacent module (rotated by about 45°); - rotate both modules to align them, ensuring that protrusion “E” slides into slots “A” and “B” and protrusion “F” slides into slot “C” until a click is heard; 6) replace the manifolds on the brackets and close the supports with clip connection.  Assembling/disassembling the modules C D PUSH AND TURN PUSH REMOVE PUSH AND TURN REMOVE PUSH AND TURN PUSH AND TURN C F B AA B CF D E C F B A 45° CA B A BC R73FPY001 2 CA B A BC R73FPY001

To shut off the fl ow of an individual circuit, close the respective fl ow meter completely. To open or close a fl ow meter: 1) remove the protective red cap; 2) manually rotate the black ring nut of the fl ow meter clockwise to close the circuit or counterclockwise to open the circuit: - the fl ow is completely shut off when the fl ow meter is completely closed; - when the fl ow meter is completely opened, the fl ow rate set with the dynamic balancing bonnet (return manifold) is circulating within the circuit and indicated on the graduated scale of the fl ow meter; 3) when the setting is complete, refi t the protective red cap.  WARNING. To ensure the correct functioning of the system, it is important that the fl ow meters are set to either the fully open position or, if it is necessary to shut off the respective circuit, the completely closed position. Do not set the fl ow meters to any position between fully open and fully closed.  NOTE. The fl ow meter is equipped with a fl ow indicator, to be positioned at the fl ow rate set for the relative hydraulic circuit. 1 2 3
