Compact Manifolds
Compact Manifolds
The JUPITER compact mixing station is a simple, mechanical mixing valve, pump and manifold station for up to twelve floor circuits. The unit can provide warm water at flow temperatures of between 10º C and 50º C to underfloor heating circuits up to 100 linear meters of 16 x 2 mm pipe.

Installation Guide
Unpacking and Initial Assembly:
In order to protect the more fragile components, they are packaged separately, e.g. the isolating valves and TRV. These should be re-attached before proceeding. Thermostatic dials to be inserted into the isolating valves are available as an option.
It is recommended that all connections are tightened up before filling and pressurising the manifold with water as they can become loose during transportation.
Our manifolds are supplied on PVC backboards to aid installation. The backboards are easily fixed to the wall with screws. If the backboard proves too wide for the available space, then it can be cut to suit.
Flow Meters:
Flow regulation was achieved historically using the flow meters but is now handled by our unique self-balancing return valves on the top bar, which automatically limit the flow-rate to the desired value regardless of how many circuits are open.
Flow meters must be set fully open, to do so the locking red cap on each flow meter should be removed using a flat-heated screwdriver as shown. The flow meters should then be unscrewed as far as possible by rotating the black bases. If an attempt is made to unscrew the flow meters when the red cap is in situ, then the glass will unscrew instead to permit cleaning.
Connecting Pipe Work:
The primary flow pipe coming in to the manifold should be connected to the primary flow balancing valve on the upper manifold and the primary return should be connected to the return pipe isolating valve on the lower manifold.
Systems with either large primary circuits or with three floors or more should be equipped with their own automatic air vent (AAV). The vents located on the manifold are only effective for the purging of air from the JUPITER system and not the primary pipe work. The primary flow and returns should be back-flushed and purged of air prior to the opening of the isolating valves on the manifold to ensure that air is not introduced to the system.
Pre-installation Electrical Information:
Each pumped manifold requires a switched, fused spur to provide power to the pump via a wiring centre. The JUPITER supplied junction box facilitates simple connection to the spur and ensures that the overheat thermostat is connected in-line with the pump. We recommend that a motorised zone valve is installed on the primary flow into our manifold, which in turn should be connected to your heat source. Consideration should be given to positioning of the room thermostats and how their cables will be run.
For detailed pre-installation electrical information, please refer to the information specific to your choice of control solution which will be sent separately.
Additional Information:
- Please note that additional space, beyond what has been suggested to allow for the manifold, will be required to facilitate the installation of ancillaries, e.g. the wiring centre for the thermostat system, two-port valves, automatic air vents, circulation pumps.
- Additional space should be allowed for on the left-hand side of the manifold for the incoming primary flow and return pipework.
- The bending radius of the pipework exiting the bottom bar of the manifold must also be allowed for, we suggest that at least 100 mm is allowed for beneath the ports on the underside of the bottom bar of the manifold.
Close the return pipe isolating valve using one of the orange caps fitted to the return bar.
01
Close the primary flow balancing valve using the cap from one of the fill and drain valves.
02
Always deburr the end of pipe with bevelling tool before attaching to manifold.
03
Place the nut and split brass olive over the pipe before pushing the Eurokone fitting it to the end of the pipe.
04
Push Eurokone insert and pipe into manifold connection and tighten the nut up with a spanner to compress the olive.
05
Connect all of the floor circuits to the manifold, then replace the caps on the fill and drain valves with Hozelock adaptors.
06
Connect hoses to the system; the upper hose attached to the return bar should be allowed to drain into a bucket.
07
Turn on the supply of water to the bottom hose attached to the flow bar, then use the square key on the outside face of the caps to open the fill and drain valves by rotating the valve stem below anti-clockwise.
08
After approximately two minutes of filling the pump will be full of water, close the red and blue isolation valves and continue filling the circuits.
09
Once no more air bubbles are visible in the water exiting the top hose, close the completed circuit’s valve using the orange cap and open the next circuit to be filled.
10
Once the final circuit has been filled, open all of the floor circuits fully by removing their orange caps.
11
Once all the circuits are filled and purged of air, close the fill and drain valves using the cap. Close the upper return valve first and then lower fill valve second. Once both fill and drain valves are closed, turn off the supply of water and remove the hoses. Then open the isolating valves in preparation for pressure testing.
12
Before connecting the pressure tester to the lower fill and drain valve, pump water through its hose to ensure that air is not introduced to the manifold. Connect the pressure tester and pressurise the hose to 4 bar before opening the valve it is connected to using the cap.
13
Open the fill valve and pressurise the system to 6 bar. Verify that the system is leak-free by leaving the system under pressure for a minimum of one hour and ensuring that the indicated pressure does not fail. Small drop-offs in pressure may indicate air in the system.
14
Once pressure-testing has been completed decrease pressure within the manifold to 2 bar and then close the return valve using its cap. Release the remaining pressure in the hose before detaching the test equipment from the manifold. Remove testing equipment and replace the cap.
15
Remove the orange cap from the return pipe isolating valve, catching the small amount of water that will escape.
16
Replace the orange cap with the TRV, inserting its copper vessel into the insert on the first port on the flow bar.
17
Refer to our heat output calculations if they have been supplied to set the correct flow rates on the self-balancing return valves using an 11 mm spanner or socket. In the absence of heat output calculations, the flow rates should be set to 2.5 L / min on the flow meters (15 x 10 L / hour on the return valves).
18
Once all of the flow rates have been set, the actuator mounting adaptor rings can be installed, followed by the actuators. Please ensure the actuators are the correct voltage for the thermostat system to be installed, typically 24 V or 230 V.
