Installation of AHU Kit

WARNING
Electric shock from live power supply cords

► Wiring installation must only be performed by a qualified electrician.
► Before starting to work on any machines or devices, always switch off the power supply
and lock it in switched-off position.
ATTENTION
!
Damage to the AHU Kit enclosure and to the thermistor and/or expansion valve wires
Exposing the AHU Kit enclosure to direct sunlight can cause overheating and material damage and
should therefore be avoided.
Exposing the wires of thermistors or, in case of the ECOi and ECO G systems, of the expansion
valve to the outside and/or to direct sunlight might damage the wires and should therefore be
avoided.
► Attach the AHU Kit either directly to the Air Handling Unit or to a wall nearby and make
sure that it is not exposed to direct sunlight.
► Use protecting wire ducts to avoid exposing the wires of thermistors and the electronic
expansion valve to the outside.
