Ready-to-install trench heaters with EC tangential fan
Assembly and installation instructions
• Use the pipe openings in the floor trench for the water-side connection
5
.
• Remove the punched pipe entry opening or use the round connection
openings for electrical wiring. Screw on the thermostatic valve and
return shut-off valve without the need for additional sealing to the
Eurokonus connections on the convector.
• Then fit the flow and return pipes.
• Perform a pressure test.
• Adhere these installation instructions very visibly to the Katherm HK for
subsequent trades.
• Cover the grille and Katherm HK with the transparent installation cover
to protect it from dirt or cement.
Important! Grilles are suitable for foot traffic. Avoid point loads
(e.g. chair legs).
Before commencing screeding, check whether
• the water connection has been correctly done,
• the electrical connection has been correctly done,
• the height of the trench heater and air flow direction are 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,
• requisite empty pipes have been laid,
• appropriate materials have been used to seal all openings and punched
openings of the Katherm HK from the ingress of screed.
• seal the openings and punched openings on the trench when using
screed or other low-viscosity floor coverings.
Important!
• Do not allow screed or the floor to press the Katherm HK. 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.
