3.2.4 Connect manifold pipework
To the flow (outlet) from the heat pipe manifold, fit the temperature sensor pocket supplied,
sealing the connection with PTFE tape (not supplied) and setting the pocket to a suitable
angle to allow the sensor cable to be secured to the flexible pipework. Either end of the
manifold can be used for the flow (whichever is most convenient) but the sensor pocket
must
be fitted on the flow (outlet) side.
Liberally apply the heat conducting paste, supplied with the manifold (SHP~), to the PT1000
temperature sensor with the
black cable
, supplied with the system controller (SSC~), then
insert the sensor into the sensor pocket. Ensure the sensor is fully inserted in the pocket.
Once the pipework has been insulated, secure the cable to the outside of the insulation using
an appropriate cable tie to prevent the sensor from coming out of the pocket.
If installing multiple collectors, connect each pair using the manifold connector (SMC~) and
sealing washers supplied with the extension kit (Solar SHPX~).
Provide effective lightening protection by connecting a suitable conductor to either the flow or
return connection of
EACH
collector installed.
Connect the pre-insulated flexible hoses (SFH~) to the return connection of the manifold and
to the sensor pocket on the flow connection using the washers provided. Route the pipes
through appropriate flashing and into the roof space. The flashing should seal directly onto
the pipes, rather than onto the insulation, as the insulation could absorb water over time and
lead to water ingress to the property.
Use appropriate fittings and sealing (not supplied) to either extend the hoses or connect to
rigid pipework then plumb the flow and return pipework to the top connections of the dual-line
pump station (SDPS~).
ALL
pipework must be
fully insulated
with
high temperature insulation
(such as Armacell
HT/Armaflex).
Solder ring fittings and standard solder joints
must not
be used, as the high temperatures
generated occasionally can melt the solder. Use only compression fittings, appropriate union
fittings or high temperature solder or braze
suitable for up to 250
0
C
.
