Operation Instructions
Starting up for the first time:
At this point all electrical power to the system is off, the cold water supply valve is off, the collector isolation valves are off and the storage tank is empty. The air vent on top of the collectors is not installed so the collectors can be flushed.
(A)
Fill the tank by turning on the main valve and allowing
the air to flush out of the tank.
(B)
Turn on the isolation valves to fill the collectors. (You
can flush the impurities like loose solder; flax, joint compound ext. from
the collectors threw the air vent thread connector).
(C)
After the collectors have been flushed, install the air
vent and pressurize the system, the automatic air vent will bleed remaining
air out of the collectors if its plug is loosened. (The system must be free
of air for the pump to circulate water).
(D)
Once the system has been filled, follow the controller’s
instructions for fine-tuning. Plug in the pump cord into the controller. Plug
in the controller to the 110V outlet and set the controller switch to
automatic operation.
(E)
The system should begin functioning if the sun is
shining. Within a few second the collectors return line will be very hot.
Within a minute or two the return line should cool to about 10°F to 15°F higher than the feed line.
(F)
Set the electrical element timer so it does not compete
with the sun.
Normal Operation Description
When solar energy is available
the automatically controlled pump circulates solar heated water from the
collectors through the solar storage tank to reach the desired temperature
(130° F to 180° F). The collector’s basic function is to capture
the suns energy and to transfer the heat collected to the fluid circulating
throughout the system.
The controllers basic function is to monitor collector and storage temperatures and to automatically turn the pump ON or OFF at the appropriate temperature.
The solar storage tanks
basic function is to store the energy collected. The tank is equipped with an
electrical element and becomes a water heater as a backup. A timer can be
added to control the electrical element so it cannot compete with the sun’s
energy.
System Maintenance
Sun-Ray Solar water
heating systems require relatively little attention. But, as with any
mechanical system, some basic maintenance is essential to keep the system functioning
smoothly.
The maintenance requirements of Sun-Ray Solar water heating system are
similar to those of conventional water heaters. The collectors, piping and
storage tank should be checked for leaks, the system should be flushed
periodically to remove tank and collected impurities (scaling in hard water
areas). The systems should be checked at least twice per year for a proper
operation of the pump, controller and sensors. The collector’s glass can be
rinsed periodically to remove dust collected in order to improve collector
efficiency.
Freeze protection
When the water in the collector reaches a temperature near freezing, the system’s freeze protection mechanisms will protect it as followed:
(A) The controller turns the pump on and off periodically to warm the collector with water from the storage tank.
(B) A flush-type freeze protection valve can be installed near the collectors opens to let warm water flow through the collector.
C) For a longer freeze duration or if a power failure and freeze condition occurs at the same time. the collector must be manually drained (see Collector isolation and drainage above).
Note: Sun-Ray Solar is the manufacture of the solar collectors for this system and offers this system major component as a package. Each major component comes with its own manufacturers warranty and its installation instructions.
The system installation is warranted by the contractor or the individual who installs the system.
Sun-Ray Solar collectors Limited Warranty
Sun-Ray Solar, the manufacturer, warrants to its
distributors, dealers, customers, and the ultimate original consumer, that
Sun-Ray Solar Collectors are free from defects in materials and workmanship
for three years from date of installation. This Warranty is nontransferable.
This Warranty does not extend to any damage or defects, caused by negligence,
freeze damage, improper installation, vandalism, or improper use. If the
collector fails to perform through defects in material or workmanship in
manufacturing, the manufacturer's sole obligation under this Warranty is to
repair or replace the defective collector without charge. Except where
prohibited or limited by applicable law, the manufacturer may require that
the ultimate consumer bear all expenses of shipment of defective panel(s) or
parts to and from its factory.
