PART 8: MAINTENANCE
Under normal conditions, the solar collector is maintenance free. Other system components, such as the
pump and glycol (if used), may require periodic inspection and changing/maintenance. Please refer to
the documentation provided by the manufacturer of these other components.
NOTE:
APART FROM THOSE MAINTENANCE ITEMS OUTLINED BELOW, ANY SYSTEM
INSPECTION, MAINTENANCE OR REPAIR SHOULD ONLY BE COMPLETED BY AUTHORIZED
PERSONS. THE SOLAR COLLECTOR WARRANTY COVERAGE MAY BE VOIDED IF NON-
AUTHORIZED PERSONS ATTEMPT TO MAINTAIN OR REPAIR THE SOLAR COLLECTOR OR
ASSOCIATED COMPONENTS.
The following basic maintenance may be completed by the HOME OWNER:
A. CLEANING
Regular rain should keep the evacuated tubes clean, but if particularly dirty they may be washed with a
soft cloth and warm, soapy water or glass cleaning solution, ONLY if the solar collector is located in a
position which DOES NOT REQUIRE climbing onto the roof or use of step-ladder. If the tubes are not
easily and safely accessible, high-pressure water spray is also effective.
If cleaning is required and the above outlined methods are not suitable, the company that supplied and
installed the solar collector should be contacted.
B. LEAVES
During autumn, leaves may accumulate between or beneath the tubes. Please remove these leaves
regularly to ensure optimal performance and prevent a fire hazard. (The solar collector will not cause the
ignition of flammable materials). Such cleaning may only be completed by the homeowner if the tubes
are easily and safely accessible.
The following maintenance may ONLY be completed by AUTHORIZED PERSONS:
C. BROKEN TUBE
If a tube is broken it should be replaced as soon as possible to maintain maximum collector performance.
The system will still operate normally and safely with a broken tube. Any broken glass should be cleared
away to prevent injury. Protective gloves must be worn when handling broken glass.
Handling broken glass must be done with extreme caution. Failure to do so may result in serious injury.
D. INSULATION
The plumbing pipes running to and from the collector should be heavily insulated. This insulation foam
should be checked periodically (at least once every 3 years) for damage. For any insulation exposed to
sunlight, ensure protective cover/wrap/foil is in good condition. Replace as required.
E. DRAINING THE COLLECTOR
If maintaining the system, or in preparation for extremely cold conditions (extended snow cover), draining
of the manifold may be required. To drain the collector of fresh water (direct flow system):
1) Turn off the water supply to the solar storage tank.
