For the efficient and reliable operation of the solar water heater, it is necessary to
follow the installation instructions that are listed in this Chapter of this leaflet.
4.1 Components of the solar water heater
The basic components of the solar water heater
Thermosiphon 150/2.5
are shown
in Figures 4.1a and 4.1b in the next pages.
The solar heater is delivered to the customer in three separate packages. One
contains the storage tank, the second the collector and the third the mounting
frame and all other required components, i.e.
- the plastic pipes for the closed loop (Figure 4.1a, components 7 and 8) and
required fittings
- the expansion tank and the safety valve of the closed loop (Figure 4.1a,
components 5 and 6) as well as required fittings
- the combined “safety and one-way” valve in the cold water inlet of the hot
water storage tank (Figure 4.1b, component 10) as well as required fittings
- two containers (one litre each) with antifreeze
- the required quantity of corrosion inhibitor
- screws and nuts for the mounting frame and for attaching the collector on
the mounting frame
It is recommended to remove all packaging material from the tank, the collector, the
mounting frame and the other components at the site, where the solar water heater
will be installed, in order to avoid damaging the equipment when moving it.
4.2 Necessary special tools and materials
The following special tools and materials must be used for the proper installation of
the solar water heater (provide list).
4.3 Removing packaging
Before starting the installation of the solar water heater, you must remove packaging
material from the storage tank and the collector, taking care not to support their
weight on the inlet/outlet connecting points. Remove the protective plastic caps
from the connecting ends of the collector and hot water storage tank.
