Fixing to round ducts with clamps.
Any mounting position except for the junction box downwards to prevent condensate leakage and short circuit.
Install a filter upstream to the heater to protect heating elements against dirt ingress.
Recommended distance between the heater and other system components must be not less than two connecting diameters for air flow stabilization.
Duct heaters are rated for minimum air flow speed 1.5 m/s and maximum air temperature supplied to the units 40 °C. In case of speed regulation with a speed controller the minimum air speed through the heater must be provided.
For correct and safe heater operation an automatic control and protection system is recommended including the following functions:
-regulation of the heating capacity and temperature of the air heated up;
-filter clogging control by a differential air pressure sensor;
-power cut-off in case of supply fan shutdown or low air flow speed as well as in case of actuating the overheat protection thermostats;
-heat removal from the heating elements after ventilation system shutdown.
