Installa on and electrical connec on

Electrical duct heaters EKA can be installed horizontally in any posi on except electrical connec on box
downward and ver cally (only if the air flow direc on upwards) (see Fig. 2).
IMPORTANT:
The installa on to the mains power supply may only be wired by a competent electrician. The power
supply cable must be selected in the ra o with power of the heater. When installing these heaters, the
standards and regula ons in force in your country must be followed strictly adhered to. Within the installa on
an electrical isola on automa c circuit breaker (not included) must be present, to enable the installer to cut all
power supply lines. Automa c circuit breaker must be selected regarding power and nominal current (see the
electrical ra ng plate on the lid of heater) of the heater and should have characteris c B. Connect the heater to
the mains power supply, check that the voltage, frequency, power and current are the same as those indicated
on the electrical ra ng plate. The heater must be earthed.
We recommend install supply air temperature sensor in distance mul plied by the heater's diameter (3xD).
For example: heater EKA diameter 200 mm, sensor's installa on distance will be: 3x200=600 mm.
