the threaded plugs in the unused ports.
!
nOTE: There are two different thickness of
shims provided to assist with ensuring that the
collectors are level and connections are sealed
properly.
14. once the solar collectors are level and plumbed
together, secure the bottom clamp assemblies,
using #10 self drilling screws. (Figure 8)
15. Loosen the bolt in the bottom clamp and slide
into groove of the solar collector and tighten to
35 lbs (15.9kg) of torque (Figure 9 - Detail A).
16. Repeat Steps 11-15 for the top clamp assem-
bly.
CauTiOn: Ensure that the final installation of
the collectors is capable of maintaining tilt and
azimuth.
17. Install the elbow connector at the Solar Col-
lector inlet and outlet. (Figure 10)

Piping

Two lines of 1/2" (12.7mm) piping, insulated to
R4.2 with uV resistant EpDM insulation, need to
be run from the Solar Collectors to the pumping
system. The lines can run either through the walls/
attic of the house or along the outside wall of the
house. Any piping that is required to run across a
surface horizontally should be sloped towards the
drain ports with a drainage slope of no less than
3/4" (20mm) vertical drop for each meter of hori-
zontal length (1/4"/ft).
!
nOTE: Stainless steel corrugated pipe is sug-
gested for use but standard insulated potable
compliant piping can be used.
!
nOTE: Stainless steel corrugated piping is
available as an optional accessory, in 50' (15.24m)
lengths, with sensor wire and insulation.
!
nOTE: If soldering rigid connections, ensure
soldered connections meet potable water require-
ments and can withstand high temperatures.
!
nOTE: Tag the inlet and outlet of the piping at
each end to help with installation.
The Stainless steel corrugated piping is equipped
with a sensor wire that can be attached to the
Solar Controller and the temperature probe at the
Solar Collectors. If using an alternative piping,
double insulated 20 ga two core sensor wire can
be used and should be covered with the uV resist-
ant insulation, with a minimum rating of R-4.2, to
protect the wire from environmental elements and
vermin.
!
nOTE: When running piping ensure that the
pipe is supported properly to prevent any sagging
or stress on any other component of the system,
and has been installed with the correct pitch to al-
low for proper drainage.
CauTiOn: When installing piping supports
ensure that the insulation is not pinched or com-
pressed, which may damage or reduce the life of
the insulation and subsequently the piping.
In the Sensor wells, in the Solar Collectors, there is
a rubber gasket.
• Remove the gasket and insert the probe
through the gasket.
• Insert the probe into the sensor well so that the
probe gently touches the end of the well.
• Move the gasket so that it seats back into the
well and secures the temperature probe.
CauTiOn: Flashing, sealing and routing for the
piping and sensor wire is the responsibility of the
installer and is not included in the kit.
When running piping from Solar Collectors to
pumping Stations ensure that the vertical runs
of piping are supported at a minimum every 10ft
(3m).

Warning: Always completely disconnect the
device from the power supply before performing
maintenance or electrical work.
Warning: Do not make any changes to elec-
trical components, the design or the hydraulic
components to prevent risks or harm to people
or material property.
Warning: Wiring procedures and connections
