Periodically, recommended every three months a general inspection should be made
and the following items checked:-
Collector condition, leaking unions, dirty or broken glass, damaged water seals.
l
Tank condition including casing damage, piping leaks and valve operation.
l
Electric heater power connections.
l
Replace worn out magnesium anode periodically.
l
Booster pump and pressure tank settings (if applicable).

Check shading of collectors
l
Once a year, it is recommended to flush the collectors to remove any settled
sediments that may affect the thermosyphon flow.
9. TROUBLE SHOOTING
DIRECT SYSTEMS
PROBLEM
Insufficient
hot water
POSSIBLE CAUSE
High hot water usage at night
Prevailing weather conditions
Non-operation of electric booster
Air locks in the collectors
Slow leaks by system or pipe work
Blockage in the connection pipes
Collectors blocked with sediments
SOLUTION
Rotation use or replace with a larger
system
Incorporate complimentary electric
heater to be used when irradiation
is low
Replace the electric heater
Ensure tank connections are higher
than collectors connection
Pressure test the pipes
Visually inspect for leaks. Raise top
right hand corner on the system
Unblock then pipes
Replace the blocked pipes
Flush collectors with clean water to
clear the sediments
Incorporate a filter in the pipework
