General
The following instructions enable authorised personnel to install the systems efficiently and safely. The
installation and safety instructions must be followed. The accident prevention regulations of the professional
associations must be observed, especially when working on the roof. If there is a risk of falling, precautions
must be taken. The entire solar energy system must be installed and operated in accordance with recognised
technical regulations. Errors and omissions excepted.
General specifications
These installation instructions describe the installation of the TS-INOX solar water heater for a sloping roof.
The main components of the system are as follows:
- Solar storage tank
- Solar collector(s)
- Mounting bracket
- Hydraulic kit
Detailed information can be found in the product nomenclature.
TS-INOX thermosiphon water heaters operate in direct circulation. The storage tank is protected against
corrosion (Inox 316L)
The hot water in the storage tank can reach more than 100°C. The maximum operating pressure is 7 bar. If
the mains pressure is higher than 4 bar, it is necessary to use a pressure reducer.
For optimum performance, the solar collectors must face south in the northern hemisphere and north in the
southern hemisphere. To ensure the production of hot water all year round, it is possible to install an electric
back-up. To avoid burns and for greater comfort, it is necessary to install a solar thermostatic mixer.
How does a thermosiphon work?
The water, circulating inside the collectors heats up, expands and becomes lighter than cold water. It rises
naturally in the storage tank located above the collectors for the thermosiphon technology. This hot water
then replaces the cold water which goes back down to the collectors to be reheated, and so on.
It is a phenomenon of natural circulation of a liquid that uses the variation of its density with temperature.
Packaging, handling and storage
The collector is packaged in two cardboard covered, reinforced by honeycomb wedges on the corners. The
tank is wrapped in a protective foam, filmed with stretch plastic film. The supports are wrapped with stretch
film, as well as the tubes of the hydraulic kit. The products must be stored indoors. Do not handle the solar
collector or the tank by the inlet/ outlet tubes. Protect the glass and the back of the collector during transport.
Maintenance
In order to ensure that the system function properly over time, it is important to carry out all the maintenance
steps mentioned in the user manual. If these steps are not carried out, the longevity of the product and its
warranty may be affected.

V07.22 Page 7of 20
Safety instructions
Roof
Before installation, make sure :
- that the roof can withstand the load of a TS-INOX water heater once filled.
- that the inclination is sufficient for the thermosiphon’s function (see page 6)
Local climatic conditions, such as snow and wind, must be taken into consideration. Please contact your
seller for more information.
Location
Make sure that there is enough space available for the correct installation of the system. Please observe
the distance to the roof edge of 1.5m. This is necessary with regard to roof statics, snow and wind loads,
as well as to facilitate the maintenance of the system. If the roof does not allow this, please consult a
structural engineer.
Roof waterproofing
In order to avoid moisture and water infiltration problems on the roof, pipes that penetrate the roof must be
well sealed. The fixing of the supports is carried out by means of anchor bolts with sealing gasket.
Additional comments
The connecting pipes must be very well insulated to avoid heat loss and UV damage.
We recommend that you declare the TS-INOX water heater to your insurance company as an added value
to the building and take out insurance against lightning and glass breakage.
Be careful:On very sunny days, the collectors can become very hot. There is a risk
of burning. Therefore, the collectors must be covered during installation. Prefer an
installation in the early morning.

Page 8of 20 V07.22
Technical instructions
Installation guide
The installation of the water heater is described in detail on the following pages. These installation
instructions are divided into three parts:
1. Installation of collectors and storage tank
2. Hydraulics
3. Maintenance
Before starting the installation, please consider the following points:
The thermosiphon solar water heater must be installed with a minimum inclination of 15°, corresponding to the
limit of use.
Antifreeze corrosion protection
The TS-INOX thermosiphon water heater must not be installed in areas at risk of frost.

V07.22 Page 9of 20
Technical instructions
Security Group
The safety groups protect the water heaters when the internal pressure reaches 7 bar. This also allows the
opening and closing of the water supply to the water heater and the emptying of the water heater by
operating the valve cap. The safety group must be connected to the gutter by a drain pipe. The drain pipe
must be free of obstructions so that excess water can drain off normally.
Electrical connection
Where a booster resistor is required, a circuit breaker must be installed. This installation must be carried
out by a certified electrician.
Lightning protection
The load-bearing structure of the collectors must be earthed. If a lightning protection device is already
provided for the building, the metal piping of the solar system must be connected to this device with a
green/yellow conductor cable with a minimum cross-section of 6 mm² Cu (H07 V-U or R). If this is not the
case, an earth spike can also be used for earthing.
Decommissioning and dismantling
The system must be disassembled early in the morning to avoid the risk of burning. Be aware of system
temperatures before starting dismantling. Cover the collectors the day before if possible, to prevent the
passage of solar radiation.

This step allows the roof to be drilled to fix the tie rods
(5.5). Drilling on high corrugations.
Position the stringers along the marks previously
made, to check alignment.
Drill holes in the roof and screw in the lag bolts (5.5).
Drill the stringers (4.1 and 4.2) at the level of the tie
rods.
Pay attention to the perpendicularity of the stringers
in relation to the horizontal.
Screw the stringers to the tie rods (5.5).
Screw the collector crossbars (4.3 or 4.4) onto the
longitudinal beams.

Lift the collectors (3) on the roof. For lifting, attach two
sturdy ropes as shown opposite. During handling,
make sure that the rope does not cover the copper
pegs. It is recommended to use a crane for lifting. If
necessary, carefully use a ladder to mount the
collectors on the roof. Work in pairs: one installer
secures the collectors, the second one guides the
collectors to the roof.
Raise the ball on the roof. For assembly, attach two
sturdy ropes as shown opposite. We recommend
using a crane for lifting. Work in pairs: one installer
secures the tank, the second one guides the tank.
