Roof Type Compatibility Guide
The average air gap distance between the mounted collector and roof structure has a strong
influence on wind loadings. If panels are to be installed on a roof then the following should
be observed to limit wind uplift potential.
1)
Installed panels
should lay flat close to the roof structure.
It is recommend the air
gap distance between the bottom of the installed collector and the valley points of
the roof corrugations should be no greater than approximately 40mm.
2)
Panels should have adequate clearance from roof edges.
3)
Panels on roofs should not be mounted on tilt frames
.
This system is
not compatible with bromide chlorination, hydrochloric acid use and/or acidic
pool/spa water (pH less than 7.2)
. Sodium Carbonate must be added to protect the system
from acidic pH (<7). pH should be maintained between 7.2-7.8 for maximum system longevity.
If required Sodium Bisulphate acid can be used to keep the pH down.
For maximum pump and system longevity we strongly recommend a non-chlorine/bromide
based sanitation method.
