3. Site Installation
3.1.
 Check the order, order reference and the delivered system sizes match.
 At the position the system is to be installed, check / mark out the system width (X),
the system draw (Y) and the diagonals (D).
 It is important that the diagonals are equal. Measure and adjust the marking out so
the diagonals are equal.
 System width (X) and system draw (Y) must be parallel.
 Refer to the installation drawing supplied with the system and mark out the fixing
positions.
 All wall fixings are to be supplied by the installer and are to be suitable for the material
being fixed to. Fixings should be M8 size.
VERY IMPORTANT –DO NOT ATTEMPT TO INSTALL THE SYSTEM UNTIL SYSTEM AND FIXING
POINT DIMENSIONS HAVE BEEN CHECKED AND FIXING POSITIONS ARE SQUARE.
3.2.
Electric power supply
 Each system should be on a switched single spur, so as to isolate each system.
 Check with the site manager to ensure that electrics are set up correctly.

Tess 100/400 Manual. Issue 1 (DR1004. October 2018)
12. Fabric Tracking And Final Tension
13.1.
The TESS systems can be fine tuned to ensure good fabric tracking and long life. Tracking
may need to be adjusted during product life.
The fabric when being retracted back towards the barrel should remain in position on the
barrel. The fabric should not move towards one side. Long fabrics might move towards one
side and then back towards the other.
 Taking care that the fabric does not crease —Deploy and retract system several times
to give accurate indication of tracking.
 Adjust the fabric tracking as required by loosening the mounting screw and
repositioning the tracking plate (this can be carried out at both sides).
13.2
Tensioning Tool –Supplied in fitting kit
 Apply 10-20 FULL turns to the gear box by using the tensioning tool (provided)
 Recheck fabric tracking.
INFORMATION
 Do not over tension system.
 The system is over tensioned if the spring cassette is locked. Simply check this by
pulling onto the tension cable to check for free movement of the spring cassette cable
spool.
