Assembly and installation instructions
6. Screeding / Protection from dirt
Before commencing screeding, check whether
• the water connection has been correctly done,
• the electrical connection has been correctly done,
• The height and distance of the trench from the window is correct,
• the grille is covered (Caution! Cement destroys the surface of the grille!),
• Sound insulation (not with raised floors) is fitted underneath the trench
heater,
• there are no sound bridges to the concrete slab, especially close to the
height-adjustment feet,
• appropriate materials have been used to seal all openings and punched
openings of the trench convector from the ingress of screed.
• the openings and punched openings of the trench convector are sealed
when using screed or other low-viscosity floor coverings.
Important:
Do not allow screed or the floor to press the floor trench.
Provide expansion joints if necessary.
Roll-up grilles packed separately, for instance when using installation covers
to protect the trenches from dirt, are rolled up in the factory. The grille can
become slightly over-long due to the steel springs extending. Unrolling the
grille and laying it flat for a few hours can return the grille to its original
length. Laying the grille into the trench, as shown on the figure above, helps
it to fit more easily into the frame.
