HXA pumping Station - depending on the type
of system you have installed - to the Solar Stor-
age Tank (See Figures 11 or 14, and 15)
2. Install the temperature probe into the Temper-
ature Sensor Well, at the bottom of the Solar
Storage Tank. Insert the probe into the sensor
well until it gently touches the end of the well.
!
nOTE: The temperature probe will be inserted
far enough in that there will be no need to secure
them into the sensor well in the same fashion as
on the Solar Collector.
!
nOTE: plumbing instructions for connecting the
Solar Hot Water System to the household water
supply are included in the Commissioning section.
CauTiOn: The installer should ensure that the
Solar Hot Water System is fully setup and func-
tioning correctly before connecting the Solar Hot
Water System to the Household water supply.

Solar Controller

Warning: Always completely disconnect the
device from the operating voltage before per-
forming installation or wiring work on the elec-
trical equipment.
Warning: never mix up the connections of
the protective low voltage areas (temperature
sensors) with the 120V connections (pump out-
puts).
CauTiOn: The Solar Controller is neither
splash-proof, nor drip-proof, ensure that it is
mounted in an area where it will not be exposed to
excess moisture.
CauTiOn: Ensure that the cover of the Solar
Controller and the secure screw has been installed
before operating the system.
CauTiOn: For safety reasons, the system may
only remain in manual operation for testing purpos-
es. In manual mode, the system does not monitor
for maximum temperatures or sensor functions.
Warning: Wiring procedures and connections
should be in accordance with the national Elec-
tric code (nEC) and local codes.
