Ventmatika EKA - Installa on and Electrical Connec on

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.
