Operating and Filling Instructions
The GeoSpring Solar system is delivered with a
protective film on the solar glass. Do not remove this
film, which blocks the sunlight, until after the system
has been filled with water. Otherwise the system
components can be damaged because the unblocked
sunlight heats up the empty system which lacks water
to absorb the heat. Remove the protective film after the
system has been filled, as it serves no other purpose. It
is recommended that you fill the system within 2 weeks
after installation, otherwise residue from the film may
adhere to the solar glass. Repeat filling and flushing
until you are sure that all air has been removed from the
system. Make sure that the maximum operating pressure
stated on the rating plate or in the installation instructions
is not exceeded. Check to make sure that all safety
components have been installed in accordance with the

light heats up the absorber.
2. It is recommended that you fill the collector before
you connect the return piping to the collector
outlet. Make sure that the system is vented to the
atmosphere. Failure to follow these instructions could
void the warranty and damage the system.
3. Close the cold water shut-off valve. Set the flow
control valves to the solar pre-heat position. Consult
system valve position drawings. Close the water
heater drain on the supply side to the solar loop
piping. Open the water heater drain on the return
side.
4. Open the cold water shut-off valve to fill the collector.
Allow the air to be purged from the system through
the open water heater drain on the return side of the
solar loop piping.
5. Allow water to flow from the system for several
minutes to flush out the collector and the piping.

cover the GeoSpring Solar under the temperature
conditions described in this manual. Appropriate
insulation or pipe heat tracing must be provided on-site to
prevent hot and cold water pipes from freezing. A mixing
valve, at which the required water temperature can be
set, must always be installed at the hot water outlet.
NOTICE:
If the temperature falls below 32°F for 8
consecutive hours, the GeoSpring Solar system
must be drained and covered. The water heater
warranty does not cover damage or failure
resulting from freezing.
The combined non-return/safety valve provided
must be installed at the cold water connection of the
GeoSpring Solar system to limit positive pressure in
the water circuit. The freeze tolerance limits are based
upon an assumed set of environmental conditions.
Extended periods of cold weather, including ambient
air temperatures below the specified limit, may cause
freezing in exposed parts of the system. It is the owner’s
responsibility to protect the GeoSpring Solar system in
accordance with the manufacturer’s instructions if the
air temperature is anticipated to approach the specified
freeze tolerance limits.
