3. Appliance description

The appliance is a wall mounted electric direct heater.The appliance is suitable as a full heating system in bathrooms, for example, or for use between seasons and as a booster heater in smaller rooms, such as hobby and guest rooms.The air in the appliance is heated by a heating element and ex-pelled via natural convection through the air outlet grille at the top. Cool room air flows in through the apertures at the bottom of the appliance.

After mounting the appliance on the wall and making the elec-trical connection using a mains plug, the appliance is ready for operation.

After mounting the appliance on the wall and making the electri-cal connection using a permanent power supply via an appliance socket, the appliance is ready for operation.

4.1 Description of the user interface

Switch the appliance ON via the switch on the r.h. side of the appliance. Set the required room temperature via the continuously vari-able temperature selector (for temperatures see specification chapter).2607310037As soon as the selected room temperature is reached, it is con-stantly maintained at this selected temperature through periodic heating (the output of the appliance must correspond at least to the required heat demand of the room).If several appliances are installed in a single room, the setting at the temperature selector on each appliance can be different. Note To avoid excessive power consumption when windows are open, switch the appliance off while airing.OPERATION Cleaning, care and maintenance www.stiebel-eltron.com CNS S | CNS U | 15 ENGLISH

4.2 Frost protection

Turn the temperature selector as far to the right as possible. In this position, the temperature controller switches on the heating element automatically if the room temperature drops below the frost protection temperature.

4.3 Limiting the temperature controller

Using the two pins fitted to the back of the control casing, you can fix the temperature controller at a certain setting or limit the temperature setting range. Break out the pins. To fix the selected temperature, push a pin into the hole op- posite (see diagram).

1 Pin 2 Temperature selector To limit the temperature setting range, set the minimum and maximum values at the temperature selector, and push a pin for each into the slightly offset hole opposite (see diagram).

Move the switch on the right of the appliance to OFF.

5. Cleaning, care and maintenance

CAUTION Burns Never spray cleaning spray into the air slot. Ensure that no moisture can enter the appliance. If a pale brownish discolouration appears on the appliance casing, wipe it off with a damp cloth. Clean the appliance when cold with ordinary cleaning products. Avoid abrasive or corrosive cleaning products. Note As part of regular maintenance, we recommend also having the control components checked. The safety and control components should be checked by a contractor no more than ten years after commissioning.

... the appliance does not heat up: Check the temperature set at the appliance and the MCB/fuse in your fuse box. The appliance has a safety temperature controller that shuts the appliance down if it overheats. After the cause has been removed (for example air outlet or inlet apertures covered) and the appli- ance has cooled down for a few minutes, operation starts again. If you cannot remedy the fault, contact your contractor. To facilitate and speed up your enquiry, please provide the number on the type plate (no. XXXXXX - XXXX - XXXXXX).INSTALLATION Safety 16 | CNS S | CNS U www.stiebel-eltron.com INSTALLATION
