Installation Guide
Unpacking and Initial Assembly:
In order to protect the more fragile components, they are packaged separately, e.g. the isolating valves. These should be 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.
Pre-installation Plumbing Information:
Primary connections to the JUPITER manifold are made using standard 1” fittings. The manifold includes 1” ball valve, which by default are mounted on the left-hand side. The end cap and isolating valves can be swapped if the primary connections into the manifold would be more easily made to the right-hand side.
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:
For pre-installation electrical information please see installation information specific to your choice of control solution.
Attach the isolating valves to the manifold.
01
Always deburr the end of pipe with bevelling tool before connecting it to the manifold.
02
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 into manifold connection and tighten the nut up with a spanner to compress the olive.
04
Repeat the previous step until all circuits are connected.
05
Close all of the return valves using their orange caps except the first circuit to be filled.
06
Prevent the escape of water by ensuring the isolating valves are closed; the wings should be perpendicular to the valve.
07
Remove the caps covering the fill and drain valves and screw on the two Hozelock adapters in their place.
08
Connect hoses to the system; the upper hose attached to the return bar should be allowed to drain into a bucket.
09
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.
10
Once no more air bubble 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.
11
Once all the circuits are filled and purged of air, close the fill and drain valves using 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.
12
Once the hoses have been removed, open all of the circuits by fully loosening the orange caps on the return valve to prepare the manifold for pressure testing.
13
Before connecting the pressure tester to one of the fill and drain valves, pump water through its hose to ensure that air is not introduced into the manifold. Connect the pressure tester and pressurise the hose to 4 bar before opening the valve it is connected to using the cap.
14
Once the valve is opened, 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 fall. Small drop-offs in pressure may indicate air in the system.
15
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.
16
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).
17
Once all of the flow rates have been set, the actuator mounting adaptors can be installed, followed by the actuators. Please ensure that the actuators are the correct voltage for the thermostat system to be installed, typically 24 V or 230 V.
