5. INSTALLATION
Ultrasun UFD solar heaters are provided with drilled frames incorporating a support cross
bar. On roofs the preferable mounting arrangement is by means of hooks affixed to the
cross bar and secured to an appropriate mounting point on the roof beams. Suspension
from the hooks is generally sufficient and fixed location is not necessary.
For ground installation rear support legs are available which should be mounted on small
concrete feet as shown below:-

GROUND INSTALLATION
The units can be installed using a gravity system or pressurised supply. Pressurised systems
are preferable as they give higher line pressures up to a maximum of 3.5 Bar. Note that in
the case of pressurised supply hot and cold lines must be pressurised at the same pressure
to ensure even temperature control. The systems are easy to plumb being provided with two
piping connections only, the inlet and outlet. It is important to fit a non-return valve and
isolating valve on the inlet line. Suggested installation layout arrangements are shown
