Pre-assembled distribution manifolds

for radiant panel systems

series 663 & 668

Function

Distribution manifolds for radiant panel systems are used to

optimally distribute the heating fluid in floor heating system circuits

and ultimately improve the control of heat emission from the panels.

The manifolds ensure that the flow to each circuit is regulated

precisely and also control the shut-off, venting and automatic

removal of air from the system.

Construction details Supply manifold Exterior shape of the manifolds and mounting brackets 663 series Supply manifold has manual balancing valves for regulating flow delivered to system circuits. The balancing is accomplished by turning an hex wrench into the balancing valve in each supply outlet. The chart on page 7 shows the number of turns for reaching the desired value of flow and ∆p. The exterior of the manifold deserves special mention because it can be cast in any shape to meet any requirements.
PAGE 4
Hydronic characteristics To determine the hydronic characteristics of the circuit, we must calculate the total pressure loss experienced by the flow of fluid as it passes through the manifold components and the radiant panel circuits. From a hydronic standpoint, the manifold unit and circuits can be shown as an assembly of hydronic elements that are arranged in series and parallel to each other.

Use of the micrometric balancing valve The micrometric balancing valves balance each individual circuit in the panels so that the actual design flow is obtained in each one. Each individual circuit consists of a micrometric balancing valve, panel piping and shut-off valve. The following information must be taken into account in order to calibrate the system correctly: · The flow of fluid that must pass through each circuit (design data).

Fitting with self-adjusting diameter for PEX and PEX-AL-PEX pipes series 680 Function The self-adjusting fitting for PEX and PEX-AL-PEX pipes is a mechanical device that allows the pipes, the radiant panel system circuits and the manifolds to be connected easily and securely. This versatile fitting has been specifically designed to adapt to the varying pipe diameter tolerances. Patented Product range Series 6805 . .

Off-center differencial bypass assembly with fixed setting code 668000 Function The distribution circuits of the heating fluid in radiant panel systems may be totally or partially shut off by closing the thermoelectric valves inside the manifolds. When the flow decreases, the differential pressure inside the circuit may rise to levels that could cause problems with noise, high rates of fluid speed, mechanical erosion and hydronic imbalance of the system itself.

Installation of the differential bypass valve on series 663 and 668 manifolds The differential bypass on series 663 or 668 manifolds is mounted by following the procedure below: 1) Remove the drain cock (A) on the upper manifold. 2) Remove the automatic air vent (B) on the lower manifold. 3) Install the differential bypass (code 668000) on the upper manifold and the lower manifold.
