10. Charging the System.
- Cont.
Your Solene solar water heating system must be charged and the fluid quality maintained by an experienced contractor. If
the system is drained during the winter, or you notice a significant drop in collector loop pressure, contact your installation
contractor immediately for service. The glycol HTF provides the freeze protection for your system and must be properly
maintained. An experienced contractor should periodically check the HTF fluid quality.
TO ENSURE MAXIMUM EFFECTIVENESS FOR CORROSION PROTECTION, THE GLYCOL INHIBITOR PACKAGE IS DESIGNED FOR A
MINIMUM 25-30 PERCENT CONCENTRATION OF GLYCOL IN WATER.
NOBURST CHARACTERISTICS -
NOBURST HD is a non-toxic antifreeze and heat transfer fluid. The product is to be used in place
of water and other water-like fluids in systems where freezing may either cause damage or interfere with the functioning of systems
or equipment and/or toxicity to humans or animals is a concern. NOBURST HD is safe for use when there is a possibility of contact
with potable water.
SYSTEM START UP-PROCEDURES -
Throughout the installation procedures outlined above, emphasis has been placed on the
correct procedures for plumbing and wiring the components, checking for plumbing leaks, pressurizing the collector glycol loop,
and eliminating any trapped air that can impact fluid quality and pump performance. Having completed these tasks it is time to
start up your Solene solar water heating system. When the glycol loop has been fully charged and the pressure is around 25 psi
(check the pressure gauge), set the differential controller to the “Automatic” setting. This will activate your circulating pump.
NOBURST CHARACTERISTICS
INHALATION
– Move person to fresh air; if effects occur, consult a physician
EYE CONTACT
– Flush eyes thoroughly with water for a few minutes. Remove contact lenses after the initial 1-2 minutes and continue
flushing for several additional minutes. If effects occur, consult a physician, preferably an ophthalmologist.
SKIN CONTACT
– Wash skin with plenty of water.
SWALLOWING
– No emergency medical treatment necessary.
The table on page 13 shows the concentrations of NOBURST HD required to provide freeze and burst protection at various
temperatures. Use the mixture most appropriate for your climate. Do not use a higher glycol to water concentration than necessary,
as this will adversely impact the relative heat transfer efficiency of the solution. Generally, for an extended margin of protection, you
should select a temperature that is at least 5°F lower than the expected lowest ambient temperature. These figures are examples
only and should not be regarded as specifications.
As use conditions are not within our control, neither Solene nor NOBLE CO. guarantees that freeze damage may not occur at
temperatures other than shown. Water used to dilute the HTF must meet certain minimum standards for purity. Impurities in the
dilution water can increase metal corrosion, reduce the effectiveness of corrosion inhibitors, increase inhibitor depletion rate,
and cause the formation of scale and other deposits on the heat exchanger’s internal heat transfer surfaces.
DISTILLED OR DE-
IONIZED WATER IS REQUIRED. THE HTF PH LEVEL MUST BE MAINTAINED BETWEEN 8 AND 10 TO MINIMIZE CORROSION AND GLYCOL
OXIDATION IN THE PIPING SYSTEM.
