Complete Manifolds

Featuring the highly versatile IVAR Combimix blending valve, the JUPITER Complete Manifold allows precise adjustment of the K_v value, simplified air bleeding and maintenance, whilst tightly controlling the flow temperature. The uniquely large cross-sectional area of our manifold bars reduces pumping inefficiencies and assures that the upgraded Grundfos pump will see a long and unstressed service life.

A suite of temperature and pressure monitoring, and flow-rate adjustment mechanisms have been incorporated within the unit’s design, and consequently our Complete Manifold offers unrivalled hydronic control and compatibility with the widest range of primary plant conditions.

New and Improved

Our Complete Manifold set has been revised to now incorporate a SpiroVent deaerator, improving system efficiency and reduce the need for manual venting through continuous removal of micro bubbles. This is not simply a pair of rails with a pump and TRV tacked on, but rather a fully-instrumented, low-loss underfloor heating station assembled from the very best components available for an efficient, trouble-free and long life.

Unpacking and Initial Assembly:

In order to protect fragile components, certain pieces are packed separately and need to be re-attached before proceeding. Firstly, the thermostatic valve linked to the copper probe needs to be attached.

Ensure that the pipe is always de-burred before attaching Euro cone fittings using a bevelling tool.

The three separately packed thermostatic dials should be inserted into the slots on the mixing valve casting.

It is recommended that all connections are tightened up before filing the manifold with water as they can become loose from 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.

Salus Overheat Thermostat:

The overheat protection thermostat is located in the upper left-hand corner of the manifold and is factory set to 60º C. This should be set approximately 10º C above the thermostatic valve setting. Full instructions on changing the default settings are delivered within the scope of delivery.

The overheat thermostat connects to a copper vessel attached to the flow bar and senses the temperature in a similar way to the TRV. When the temperature set on the overheat thermostat is reached, the live supply to the manifold pump is interrupted to prevent the apparent high flow temperature from damaging the floor finish.

Pre-installation Plumbing Information:

Primary connections to the JUPITER manifold are made using standard 1″ fittings; the manifold includes 1″ ball valves. The vents located on the manifold are intended for purging air from the JUPITER system, they will not purge air from the primary pipework. The primary flow and return pipes should be back flushed and purged of air before the primary isolating valves are opened. The installation of a de-aerator such as a Spirotech SpiroVent will continually remove air from the system, guide against corrosion and improve system efficiency.

To prevent the build-up of sludge and dirt in the manifold, and the rest of the heating system, we recommend that a dirt separator such as the Spirotech SpiroTrap is used.

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.

The flow rates through each circuit are set on the DynaCon self-balancing top valves. The desired flow rate is set against the index mark (set in 10 L / hour whereas flow meters are set in L / minute).

In the absence of heat output calculations, the flow rates should be set to 2.5 L / minute (15 x 10 L / hour).

01 Close main flow and return isolating valves. Close all of the blue caps on the return valves except the first circuit to be filled.

02 Ensure that the pipe is cut squarely and deburred with a bevelling tool before attaching it to the manifold. Place the nut and split brass olive over the pipe before pushing the Eurokone fitting in to the end of the pipe.

03 Push Eurokone insert and pipe in to the manifold connection and tighten the nut up with a spanner to compress the olive.

04 Repeat this process until all of the floor circuits have been connected to the manifold. Ensure that all of the nuts are tight before proceeding.

05 Remove the caps covering the fill and drain valves and screw on the two Hozelock adapters in their place.

06 Connect hoses to the system; the upper hose attached to the return bar should be allowed to drain into a bucket.

07 Using the caps, open both fill and drain valves by rotating the valve stem below anti-clockwise. Turn on the supply of water to the flow (bottom) hose.

08 The blue cap shown removed to ensure there is a flow of water through the circuit. After approximately two minutes of filling, the pump will be full of water.

09 Using a 6 mm allen key, close both the top and bottom internal pump isolating valves. The slots should be horizontal when they are closed. When the pump isolating valves are closed, the first circuit will begin being thoroughly purged and more air bubbles will emerge from the return hose.

10 When no more air bubbles are visible in the water exiting the top hose, close the complete circuit’s valve using the blue cap, and simultaneously open the next circuit to be filled.

11 Once the final circuit has been filled, open all of the floor circuits by removing their blue caps.

12 Re-open both the top and bottom internal pump isolating valves. A few more bubbles are likely to emerge at this point.

13 Once all the circuits and pumps are filled and purged of air, close the fill and drain valves using the caps. Close the upper return valve first, and then the lower fill valve second. Once both valves are closed, turn off the supply of water and remove the hoses.

14 Before connecting the pressure tester, pump water through its hsoe to ensure that air is not introduced into the manifold. Connect the pressure tester to the lower fill valve using the cap.

15 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 idnicated pressure does not fall. Small drop-offs in pressure may indicate air in the system.

16 Once the pressure testing has been completed, decrease pressure within the manifold to 2 bar. Then close the lower fill and drain valve using its cap.

17 Decrease the pressure within the pressure tester before removing it. Catch the small amount of water that will escape when it is removed.

18 Ensure the TRV is fully seated on its valve, and that its copper vessel is snugly inserted into the bottom of the manifold, adjacent to the flow bar. Ensure the small diameter pipe is not kinked.

19 Flow temperature setting on the TRV: If heat output calculations have been produced in response to heat loss data, then these will indicate the flow temperature to be set on the TRV. Otherwise, 40° C should be set if timber or resin floor finishes are installed. If a tiled floor finish is installed throughout then this may be increased to 45° C.

20 Salus overheat thermostat: The overheat protection thermostat is co-located with the grey junction box, and is factory set to 60° C. This should also be set approximate 10° C more than the TRV setting.

21 Setting flow-rates on the Tacanova flow meters: The Tacanova flow meters allow the installer to set the flow-rate through each circuit. The red cap is first removed, and then the black base is rotated anti-clockwise to increase the flow-rate, or clockwise to decrease the flow-rate or even isolate the circuit. If heat output calculations have been produced for the project in response to heat loss data, then these values should be used, otherwise use 2.5 litres per minute.
