Before commencing screeding, check whether

• 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 in the trench heater from the ingress of screed.
• the openings and punched openings on the trench are sealed when using
screed or other low-viscosity floor coverings.

Provide expansion joints if necessary.
