ADDITIONAL PARTS REQUIRED
In addition to the parts supplied with your panels you will need to purchase the following items from
your local hardware store:
¼" Corrosion Resistant Lag Bolts (length to fit your roof structure)
Pipe Brackets
PVC Pipe-2"
PVC Fittings-2"
PVC Solvent Cement
PVC Primer
Black Paint
Sealant (Compatible with your roof material)
PANEL INSTALLATION SEQUENCE
When transporting panels to the roof or rack and while positioning panels before mounting, be sure
they do not strike or drag over any sharp surfaces (such as nails, corners of ladders or roof eaves).
1. Survey area to confirm proper fit.
a) If multi-bank installation, plan piping configuration.
b) If roof is cedar or shake shingle, locate sub-roof support member (stringers) and mark as
appropriate for placement of the hold down clamps.
c) If you are constructing a rack for the panels be sure to consult your distributor for proper pitch
and dimensions.
2. Place two hold down brackets on each top header in the system.
3. Lay down the first panel. Be certain it is straight and square on the roof.
4. Couple all panels in a bank together.
5. Make sure panel alignment on the roof is straight. The panel bottom header should be inclined
toward the end cap approxamately ¼" every ten feet to ensure drainage.
6. Secure the hold down brackets to hold bank of panels in place.
7. Install the vacuum relief valve and end caps.
8. Connect supply and return pipes to panels.
a) These pipes should be routed so that the system will drain completely when the pump shuts
off. Additionally, a drain plug or hose bib can be installed at the lower portion of the system,
which will allow the system to be drained manually when freezing conditions occur.
9. Be sure the return pipe(s) are from the common high point of the system.
