This measure assures the user has hot enough water to use while disinfecting the top of the cylinder and hot
water pipes. Alternatively the cylinder immersion should be set to 60
C and again timed to heat cylinder every
evening.
3.4 Material Safety Data Sheet.
The anti-freeze used in a non-hazardous, non-flammable liquid. Material Safety Data (MSDS) sheets are
available on request.
3.5 Electrical Safety
Under no circumstances should the controller or pump be opened especially while the power is still connected.
4.0 System Maintenance
4.1 Owner Maintenance.
Periodically check in the evening time that the pressure is still as per the commissioning pressure, if not contact
the installer/commissioner. Failure to do so may make your system less effective and may damage circulating
pump. Regularly check if the system is operating during the day and heating the cylinder. The owner should be
aware of any shading developing, i.e. from next door neighbour or own vegetation. In areas of construction the
glass panes may develop a sheet of soiling which is not washed away by rain and will require washing.
4.2 Professional Maintenance. (Frequency: every 12 months)
Collector glazing and seals
Look for cracks in the collector glazing, and check to see if seals are in good condition.
Collector soiling
Dusty or soiled collectors will perform poorly. Periodic cleaning may be necessary in dry, dusty
climates
Plumbing, ductwork, and wiring connections
Look for fluid leaks at pipe connections and components. Check pipe seals.
Piping and wiring insulation
Look for damage or degradation of insulation covering pipes, and wiring.
Roof penetrations
Flashing and sealant around roof penetrations should be in good condition.
Storage systems
Check storage tanks/vessels, for cracks, leaks, rust, or other signs of corrosion.
Pumps
Verify that circulation pump is operating smoothly.
Heat transfer fluids
The antifreeze should be checked for a freezing point of -25
C to -35
C, if the freezing point is between
-25
C and 0
C then the antifreeze should be replaced back to -35
C. The ph of the antifreeze should
remain at approx 7.0
1, otherwise the antifreeze should be replaced.
