10.4
Connections
Ensure the sealing washer provided is inserted between the
male and female connections. All connecting pipe work and
fittings must be of a suitable metal; either copper, brass or
stainless steel. Soft soldered joints must not be used. Any seals
or sealing compounds must be resistant to temperatures of up
to 200°C and be resistant up to a 50% glycol/water mix.
When tightening the connections, always apply counter-
pressure with a wrench or another spanner to prevent
damage.
10.5
Collector inclination for Pitched Roof Mounting
The collector is suitable for angles between 0 - 90°.
The roof aspect should ideally face South, however
orientations between 30° East and 40°West of South are
acceptable. Fig. 19 shows the efficiency loss for varying angles
of inclinations and roof orientation (Portrait & Landscape).
10.6
Solar fluid
The Baxi Solarflo
TM
collector tubes MUST be protected with
the supplied fluid.
Top-ups cannot be made with water,
only
use the fluid supplied (Tyfocor LS). Systems found to have
lower glycol concentrations will not be covered by the
warranty.
10.7
Collector location
Under no circumstances should the collector be fitted where it
overhangs any part of the roof structure.
Minimum clearances must also be adhered to for servicing and
or replacement of parts (see Fig. 20).
