Installation instructions – Wooden frame collectors
In-roof installation
SAFETY INSTRUCTION!
The basic equipment
includes:
+ safety shoes
+ hard hat
+ cut-proof safety gloves
+ safety harness
Ladder
Lean ladders only on strong and secure support points. Before climbing, be sure that the
ladder can not exile, fall over or sink in. Circulation lanes next to the site should be blocked
in order to avoid any risk of accident due to fall of objects.
Damaged ladder should not be used (nor patched up).
Up on the roof
At heights of more than 3 metes and for works on roofs with inclination between 20 and 60
Must take protection and safety measures against risks of fall. This can be done by using
scaffold for roof works or safety harnesses.
Wind gusts
Solar collectors and their accessories, such as covering frames, are of large area
and can be subject to wind gusts. One must be very aware of this phenomenon and be
sure of one’s stability. In case of strong wind, installation should be interrupted.

Installation instructions – Wooden frame collectors
In-roof installation
BE VERY CAUTIOUS WITH….
Roof’s stability
Before any installation, it is imperative to check the good state of the roof’s substructure and
its load-bearing capacity. Particular attention should be paid the timber substructure with
regard to the durability of screw connections.
The indications of this notice are only valid within the frame of the following restrictions:
- Roof inclination 20 ° - 45°
- Maximal building’s height 25 m.
- Wind speed inferior to 150 km/h
Ventilation
It is imperative to build a sufficient air circulation underneath the collectors. This ventilation
avoid the stagnation of water underneath the collector in case of heavy rains.
Contamination Prevention
During the installation phase, all ventilation holes and connections must be protected against
contamination and clogging.
Flushing and filling
For safety reasons, you should only fill the collectors when the sun is not shining (or cover
the collectors). You should use a mixture of antifreeze with water (40% antifreeze), Tyfocor
LS is recommended. Filling should always be done with the recommended heat transfer fluid.
It is recommended that the use of a solar filling pump is used in order to completely de-aerate
the panels and the system.
We recommend to fill the system with a pressure filling pump to eradicate any air bubbles
within the solar collector and pipework.
Operating pressure
The maximum operating pressure is 9 bar, recommended operating pressure is 3 bar with
pre charge pressure of expansion vessel set at 2.5 bar.
Check heat transfer fluid
The heat transfer fluid must be checked every 12 months with regard to its antifreeze and pH
value. We recommend to use Tyforcor LS fluid
Maintenance of the collector
The collector or the collector array must be inspected visually, once a year, for any damage,
leaks and contamination and also antifreeze level checked as the above recommendation.
avoids the stagnation of water underneath the collector in case of heavy rains.
