Note

The tube holders on the mounting

rail must be in line with those in the

connecting chamber; where neces-

sary, align with a piece of string.

3. Tighten the mounting rails with the

clamping bolts.

4. Where several collectors are

installed side-by-side, continue

with "Installing the connecting

chamber" on page 25, otherwise

Determining the collector row distance "z"

When installing several collectors in series, maintain a distance of "z" (see

page 20).

Example:

Würzburg, is located at approx 50° latitude.

1. Determine the angle of the sun β.

This should be chosen so that the

midday sun on 21.12. falls on the

second row of collectors without

being obstructed by shadows.

In Germany this angle (subject to

latitude) lies between 12° (Flens-

burg) and 20° (Freiburg).

Solar angle:

90 ° −23.5°−latitude

(23.5 ° should be accepted as con-

stant)

90 ° −23.5 °−50° = 16.5°

2. Calculating dimension. z:

h = 2020 mm

α=45°

β=16.5°

Fitting the support frame

Turn T-slot bolt 90° for all installation steps.

Position the collector array as far south as possible; longitudinal tube axis

aligned east-west.
