3. System Components
Cylinder (3C382B/3C510B/3C382HP/3C510HP), 3C Control Panel, 3C Jig.
This package supplies all the components required for a full system, except for the connecting pipes.
The connection saves considerable installation time, is neat and provides for easy connections to the
rest of the system. The system must be installed by a competent person and be installed in
compliance with this manual, all current legislation, codes of practice and regulations for
each component part.
3.1. Connection
The 3C Jig is designed to speed up the installation of Solar 3C. The individual components have
been mounted on a board as close as possible with accessible flows and returns for each
part of the system. Ideally the Control Panel will be mounted close to the jig to reduce the
cabling requirements.
The connection is 450W x 650H in size and designed to be fixed to a wall near the cylinder in
either horizontal or vertical position. Pipes need to be joined to the cylinder, boiler and heating
system at the points illustrated in the diagram. Note that the flow and return are connected to the
Solar 3C Cylinder top coil in the reverse to that which may be expected because it concentrates the
heat lower down and encourages a more even distribution of heat in the cylinder.
The under floor heating will require its own pump (not supplied) in order to provide the necessary
flow rate through the pipes without affecting the radiators. This is illustrated on the plumbing
diagram. The pump size is as specified by the under floor heating design. The pump is controlled by
the heat demand actuators on the under floor heating manifold.
The under floor heating mechanical standard control mixing valve on the heating manifold is to be
set at the specified design temperature on completion of all commissioning procedures. The
separate UFH pump assembly is recommended for the following reasons: Should the temperature of
the supply flow be too high (for example, when the heating is being supplied directly by the boiler)
the return water will be mixed with the flow reducing the temperature to the manifold to
that specified.
