(3.3.1) Roof fixing kits
MS System
Technical product description
�
The MS Sy stem is supplied as standard with the THERMOMAX MS manifolds. The patented
stainless steel bands provided are suitable for pitched roof tiles, especially slated roofs.
KS System
The optional KS System is similar in its application to the MS System. It is also used on
pitched roofs with roof tiles. The use of this system is recommended for stone/brick tiles, as a
bigger distance has to be overcome between the rafter and the support frame of the THER-
MOMAX � sy stem.
FS System
The optional FS System is to be used for flat roof or ground installations. It contains a complete
frame set, manufactured out of stainless steel, allowing the system to be installed under
different inclination angles on a flat roof or the ground. Basically the heat-pipe works under
angles between 25° and 50° with the optimum angle of the solar radiation being equal to the
geographical latitude of the system location.
Alternative mounting methods
The THERMOMAX � solar collector system can also be fixed directly to a concrete roof, a solid
wall or a copper roof. It is possible to secure the support frame to the rafter using either the
MS or the KS system by using a noggin. A noggin is a beam between two rafters. Figure 5
shows one alternative roof mounting option.
(3.3.2) Solar Differential Controller
Figure 5
THERMOMAX � manufacturers a compact and easily installed control device that will regulate
the flow of water from the collector to the heat exchanger in the hot water storage tank using
microprocessor technology. The control unit will automatically operate the pump according to
conditions set by the installer.
Pump Control Unit
The pump control unit is a fully assembled group of components mounted on a back plate,
enclosed by an insulated cover and includes the following parts:
