Adjusting setting depth - joint with standard thermal insulation
The mechanical depth stop enables the
fastener setting depth to be adjusted exactly.
For the basic setting the setscrew (11) must
protrude approx. 10 mm (see Figure 4.1).
Counter-clockwise rotation:
The fastener is set lower.
Clockwise rotation:
The fastener is set higher.
Correct setting:
When the disc lies flat on the insulation or on
the waterproof membrane and cannot be rota-
ted any more using two fingers (see Figure
4.2 and 4.3).
Adjusting setting depth - joint with Rockwool Megarock thermal insulation
Fastener/stress plate combination:
Only IR2-M-4,8xL are used in combination with IF/IG-C-82x40
Depth stop adjustment:
To ensure the fasteners are not overdriven, the correct adjustment of the depth stop is
very important (see Figure 4.2 and 4.3).
Procedure for depth stop adjustment:
1. Adjust depth stop such that the discs can just be rotated by hand
(min. 3 attempts).
2. Turn the depth stop screw back by 1.5 mm (1¼ turns, min. three attempts).
Approximate tested, established settings:
Roof construction (from bottom to top):
• Corrugated decking thickness 0.75 mm
• Rockwool Durock 100 mm
• Rockwool Megarock 60 mm
• Plastic membrane TPO/FPO 1.8 mm
Requirement, corrugated steel decking: thickness ≥ 0.75 mm
Instruction
Detailed instruction of the installer by an SFS trainer is imperative.
Changing sockets
The E320 hexagonal socket will be worn out after approx. 3000 insertions, depending
on the application; the socket must then be replaced (see Fig. 5.1). Press the spring-
loaded pin with a pointed object and pull the socket downward.
