1. Loosen lower edge of shingles above boot, under which boot-flashing will be inserted.
2. Push boot over ends of line-set and control wire, and down to roof surface (Fig. 5.4.2).
3. Carefully lift shingle above boot and generously apply
sealant to both surfaces.
4. Insert upper boot flashing under shingle and press
shingle down firmly.
5. Lift remaining edges of boot and generously apply
sealant to underside. Press down firmly.
6. Screw roofing screws through boot-flashing into roof
(Fig. 5.4.3)
7. Seal boot cavity around line-set with suitable sealant.
6 – Solar Collector Installation
Preparation of collectors for mounting includes: left to
right conversion (if necessary), installation of temperature
sensor and installation of mounting brackets.
Plastic foil sheet must remain on collectors until
pressurization of heat-transfer fluid is complete. If
collectors are exposed to sun during appliance
charging and before pressurization, flash boiling and
damage of heat-transfer fluid will occur and there is a
danger of scalding. Do not remove plastic caps
from collector tube- ends until ready to make
collector line-set connections.
As collector connections emerge from only one side of
collector, they can be described as left- or right-collectors,
depending on location of stagnation-control device (Fig.
6.1.1).
