INSTALLATION INSTRUCTIONS
SOL 27 PREMIUM S & W COLLECTORS - 230016 & 230017
single pane safety glass. As the light strikes the absorber
plate, it is converted to heat. The highly selective vacuum
coating of the absorber and the thermal insulation on the
back of the absorber keep heat lossed to the environment to
a minimum.
The thermal energy produced by the collector is transported
by the heat transfer medium (solar loop fl uid), via a
circulating pump, to the storage tank(s)/ The inside of the
collector can fog up under certain operating conditions
(e.g., large tank with low temperature compared to the
outdoor temperature and/or high relative humidity). Vent
holes are provided in the collectors for venting humidity and
equalizing air pressure.
