mounting surface and mark the fixing position. The third fixing screw
will pass through the hole in the condenser matrix. The retaining clamp
is fitted over the screw (as shown below), which can then be tightened
to retain the condenser matrix.
•
Connect the flow and return pipe work from the base unit to the fittings
on the heat dump labelled “FLOW” and “RETURN” and secure the
pipes to the mounting surface so that the weight of the pipes is not
being carried on the heat dump fittings. Do not kink the pipe work, as
this will restrict coolant flow. Do not insulate the pipe work. (Pipe work
mounted on an exterior surface may be insulated if it is felt that due to
extreme conditions freezing may occur). Do not strap the flow and
return pipes together as heat transfer between the two will affect the
system’s performance.
•
Route a twin core 24-volt supply cable through the lower guide tube
and then through the strain relief grommet positioned below the two
way terminal block on the condenser matrix. The wires are not
polarised and may be fitted either way round.
•
Ensure that the amount of cable entering through the main cover is not
excessive and cannot become entangled in the fan blade. Tighten the
strain relief grommet to support the cable. This should not be the only
means of support for the cable, therefore fix back to the mounting
surface at regular intervals along the cable length.
•
After the condenser matrix is fully fitted to the mounting surface, hang
the cover/fan assembly onto its hinges.
•
With the cover/fan assembly open, connect the wires from the fan to
the terminal block. Ensure that the wiring from the fan is routed
through the plastic clip provided to prevent the possibility of the wires
becoming entangled in the fan blade (as shown on the next page)
