3. Apply sealant to top flange of collector, making a continuous 5 mm bead along
each side of the holes.
4. Place panel on flange (bulged side facing upwards) and align bolt holes in flanges
with drift pin.
5. Bolt panel and flange together using bolts, washers and nuts supplied.
Use washers between panel and bolts.
Follow the torque value specified on the panel serial plate. Torque should
be applied crosswise and in a least two stages. Torque values are based
on new free running bolts coated with light oil. After initial start-up, check
torque values.
6. Assemble the explosion detection device (bracket and signalling cable) and place
into position. The signalling unit including cable loop must be integrated into the
threaded cable connected in such way that the loop is matching the other side
of the explosion panel.
7. Pull the steel cable carefully through the cable loop and fix both mounting eyes
with the mounting screw (min. M10) of the vent panel.
8. Now pull the signalling unit carefully to a slight tension and tighten the threaded
cable connection. The cable shall be at the crest to the dome of the panel or lead
straight across in case of flat panels.
Do not bend the stiffened part of the cable as damage could occur.
It is mandatory that the cable connection is pulled tight otherwise the signalling
unit does not break and no alarm signal is actuated. This means that no alarm
contact or plant shut off is triggered. Heavy damages (e.g. due to further
transport of burning material or uncontrolled product release) can be the
consequence.
