DESIGN AND OPERATING PRINCIPLE

• The control box is rigidly fixed to the heater casing and covered with a detachable cover. The control box incorporates:
  • fasteners for the electric heating element
  • electric components for connection to power supply
  • ground screw clamp
  • manual reset thermal switch TK-90
  • automatic reset thermal switch TK-50
• The electric cable gland for power cable as well as the connector for connection to the air handling unit are located on the front panel of the control box.
• The tubular electric heating element is incorporated inside of the heater casing.
• The casing, the connecting box and the heater cover are made of galvanized steel.
• The heater casing is heat-insulated with 20 mm mineral wool layer.

INSTALLATION AND SET-UP

Do not remove the plugs before the heaters are connected to the air handling unit. Make sure to cover the socket connector with the plugs after dismantling of the connecting cable. If only one heater is connected, do not remove the plugs from the other socket connector that is not in use. If the socket connectors are not covered with plugs for any reasons, the ventilation unit does not start during connection to power supply and the control panel displays DI1 and DI3 errors for EVH. Turn the unit off and cover the socket connectors with the plugs to troubleshoot the errors.

• Air duct connection to the heater
  • The heater is designed for inline mounting in the air duct both horizontally and vertically.
• Heater connection to the air handling unit
  • Connect the heater and the air handling unit using the cable with DB-9M connectors through DB-9F external connectors. The external connector of the heater must be connected to the external connector of the air handling unit prior to connection of the heater and the unit to power mains! ****

Heater position
In case of horizontal mounting position the control box cover must be directed upwards only. The maximum deviation angle is 90°. The control box cover may not be positioned downwards!

CONNECTION TO POWER MAINS

• Heater connection to the air handling unit
  • The connection must be completed prior to connection of the heater and the air handling unit to power mains!
  • The electric heater an the air handling unit must be connected via the cable with the prewired connectors DB-9F.
• Heater connection to power mains
  • Connect the heater to AC single-phase 230 V / 50 (60) Hz power mains using a pre-wired power cable with a Euro Plug.
