Configuration 1: Manual System
Advantages:
Disadvantages:
* No extra pump or motorized three way valve required
* Manual systems needs to be turned off/on
* Only filtered water runs through collectors
* Large main filter pump needs to be run for solar
* Requires specialized motorized valve and controller to
automate
* Increases pressure and decreases flow rate in the filter
system
Configuration 1:
Manual or motorized three way valve (9). (Note: automatic controls are omitted for clarity).
When installing PVC lines, attention should be given to the minimum spacing for pipe
supports and thermal expansion of long length of pipe work and the stress this produces
on joins. For complicated installations we recommend a professional installer install the
system, unless you are confident of the work to be performed.
Collectors must be installed with a
vacuum release valve
on the return line and a
non-
return valve
on the pump. Installations without these components will expose the
collectors to strong negative internal pressures which could fatigue work, and/or result in
significant shrinkage of the collectors which would put strain on roof attachments means.
