Standard Manifold

Installation Guide

Unpacking and initial assembly.


In order to protect fragile components, certain pieces are packed separately and need to be attached before proceeding.

Isolating valves packed separately. 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 the manifold with water as they can become loose from transportation.


The surface mounted manifold cabinet should be fixed to the wall by simply drilling holes through the metal cabinet and fixing to the wall with screws.

Extra caution should be taken when installing flush mounted cabinets to ensure that the wall depth is compatible with the cabinet.


Pre-installation - Plumbing information


Primary connections to the JUPITER manifold are made using standard 1” fittings. The manifold includes 1” ball valves. Primary pipe work for surface mounted cabinets should preferably be run to enter the manifold cabinet from beneath and left. Flush mounted cabinets come with punch out panels on the side so primary connections can enter from the left side or from beneath.

Systems with either large primary circuits or with three floors or more should be equipped with it’s own automatic air vent device. The vents located on the manifold are intended for purging air from the JUPITER system and not the feed pipe work. The primary flow and returns should be back flushed and purged of air prior to the opening of the connected ball / isolating valves.


Pre-installation – Electrical information


For pre installation electrical information please see installation information specific to your choice of control solution.


Flow meters


Simply leave open unless otherwise advised. The ideal flow rate is between 1.5 -2.4 l/m and can be adjusted if necessary.

Fix isolating valves to the manifold.

Always deburr the end of pipe with bevelling tool before attaching to manifold.

Place nut and brass split ring over pipe before inserting Eurokone fitting.

Push Eurokone insert and pipe into manifold and tighten up with spanner.

Continue procedure with all circuits.

Close all blue caps on the return manifold except for circuit to be filled.

Close isolating valves.

Open fill and drain valve using key on the back of cap.

Attach Hozelock fittings.

Fill via the lower valve and connect return hose to upper valve and allow to drain into an outside bucket.

Once no more air bubbles emerge, simultaneously close the completed circuit and open the next one.

Once purged with air close fill & drain valves using cap. Close upper return valve first then lower fill valve. Only then turn off water supply and remove hoses.

Once purged with air close fill & drain valves using cap. Close upper return valve first then lower fill valve. Only then turn off water supply and remove hoses.

Connect pressure test equipment to upper return valve. Before connecting pressure test pump some water out  through the connecting pipe to avoid pumping unnecessary  air into system. Before opening return valve with cap bring pressure up to approx. 4 bar.

Once connected pump up to 6 bar.  Once satisfied that there are no leaks, leave on test for a minimum of 1 hour.

Once completed decrease pressure to 2 bar and then close return valve using cap. Release remaining pressure before removing test equipment from manifold. Remove testing equipment and close cap.
