INSTALLATION – SOLAR COLLECTORS
Maximum Height To Collector
The solar collectors must be the highest point of the system. The maximum height of the solar installation,
from the base of the solar storage tank to the top of the solar collectors, is 7.5 m for this closed circuit system.
The pump supplied with the solar storage tank will not circulate closed circuit fluid through heights greater than
7.5 m and solar gain will not be achieved.
An additional or auxiliary pump cannot be added to this system, nor can the pump supplied with the system
be replaced with another pump, to increase the maximum height of the system.
Note: The top of the solar storage tank must be a minimum of 500 mm below the bottom of the solar collectors
for the system to operate correctly.
