3 THERE S A REASON WHY THEY RE CALLED QUICK CONNECTION MODULAR MANIFOLDS Manifolds enable the fluid circulating through a circuit to be distributed into different secondary pipes in central heating and cooling systems. Modular manifolds have been designed to connect the modules between them quickly. The fact that they are easy to fit means that you can connect as many modules as necessary, achieving a flexible product that meets the requirements of every installation. The water tight seal between each module is achieved by using an O-ring that is fitted inside the modules. There are 3 modules that have valves inside: lockshield, flow regulator and thermostatic valve, as well as an initial module, which the shut off valve and a final module are connected to, in which the purging device and drain valve are fitted.

4 INSTALLATION It is recommended that the modules are kept in their packaging until they are ready to be installed, as this will ensure that the sealing areas remain perfectly clean. Preparing the manifold The installation of the manifold starts by joining the modules together manually, making the short male connector on one of the modules coincide with the short female connector on the other. Once the modules have been joined you have to turn one module within the other as far as it will go. To finish, make sure that one part no longer turns within the other, and push the locking mechanism into position with a tool. Carry out the steps described with as many modules as necessary. Once all the modules have been installed you need to fit the final module with the purging device and the drain valve following the procedure described above. Then install the initial module. The shut off valve will be the last element to be connected.

5 Supports The modules will then be fitted onto the supports. The support will always be installed on the initial and final modules. If necessary the whole unit can be fitted in a metal inspection box. Pipe connection The last step in the installation consists of connecting the pipes to the manifold, using the right pipe connecting nut in each case. Balancing the installation The correct balancing of the underfloor heating system is essential for it to work properly. Circuits in these installations tend to be of different lengths and return temperatures (and therefore the flow is also different). In order to ensure the right amount of heat is emitted in each room, the system needs to be thermally and hydraulically balanced. For hydraulic balancing, the return manifold may be fitted with lockshield valves or flow regulators. The latter has the advantage of carrying out the function of a flow meter and a lockshield valve in a single part. Thermal balancing requires the use of thermometers. A single thermometer is placed on the supply manifold, as the water flows at the same temperature in all the supply circuits. However, the return may be fitted with either a single thermometer, which provides us with an average for the return temperatures, or a thermometer on each way. The latter option provides an exact reading of the return water temperature on each way. Connecting thermoelectric heads The thermostatic valves may be replaced by thermoelectric heads, so that each head is connected to a thermostat in order to regulate the installation. If thermoelectric heads are fitted onto all the manifold ways, a differential pressure valve has to be fitted between the supply and return circuits. The differential pressure valve keeps the pressure constant in the central heating system; in other words it keeps the pressure constant between the pump outlet and inlet. This prevents any vibrations and noise in the valves. Removing the modules If you need to remove the manifolds or fit another module, you have to release the locking mechanism using a tool, and then turn the modules and pull horizontally.
