personnel and comply with all IEE and local regulations. Failure to do so could
result in personal or fatal injury.

By default, the power cable of TectoPromo MD4 Visio is located on top of the
cabinet.
4. Operation
The cooling is achieved by a fan evaporator system. The evaporator is located at the bottom
of the cabinet’s tray. The cold air is blown to the shelves through the perforated back wall and
through the cooling cell in the top corner.
The cabinet is equipped with an electronic controller. In case the pressure rises to high, for
example because of dirt in the condenser, the controller stops the machine from running and
shows an error message (HA2).
On TectoPromo MD4 Visio, there is no separate switch for cabinet lights. The lights are
controlled by a button located on top left of the controller’s display panel. Please see the
picture on chapter Control device.
For more information on the control system, please see the corresponding chapters.
