Appliance description

This appliance is wall mounted and is particularly suitable for work rooms, kitchens, bathrooms, wash rooms and similar.
The external casing of the appliance is made from stove-enameled sheet steel. The sides are made from plastic. The controls are located on the r.h. side panel.
The quiet fan draws in the ambient air that is heated by a bare wire heater element. The air then exits evenly through the hot air channel and the air outlet grille set into the
bottom of the appliance.
The appliance heats up the ambient air inside the room and maintains it at the selected temperature.
After mounting the appliance on the wall and making the electrical connection using a mains plug, the appliance is ready for operation.
4. Operation CK 20 S

1 Temperature selector
4.1 Starting heating
The temperature is infinitely adjustable. The appliance switches off as soon as the selected room temperature has been reached.
Turn the temperature selector clockwise to the required setting.
4.2 Control with external room temperature controller
In rooms larger than 20 m you can operate the appliance with a conventional external room temperature controller.
To do so, turn the temperature selector fully clockwise.
4.3 Stopping heating / Frost protection
Turn the temperature selector fully anti-clockwise.
This position ensures frost protection. The heater starts automatically if the room temperature drops below the frost protection temperature.
4.4 Taking the appliance out of use
Pull the plug from the power socket.
5. Operation CKZ 20 S

Temperature selector
Rocker switch position (Operation with the time switch)
Rocker switch position (Standard operation)
Time switch
Marker arrow

5.1 Starting heating
Use the rocker switch to select one of the following operating modes:
– Standard operation
– Operation with the time switch
Standard operation
The temperature is infinitely adjustable. The appliance switches off as soon as the selected room temperature has been reached.
Turn the temperature selector clockwise to the required setting.
Operation with the time switch
The 24-hour time switch has 96-time segments. Every hour is divided into 4-time segments of 15 minutes. The time switch has to be reset when commissioning the appliance and after any power interruption. To do this, turn the time switch clockwise until the marker arrow points to the current time. To select the required heating time, proceed as follows: Press down the time segments around the circumference. Red markings will become visible, indicating the preselected heating time at which the appliance automatically
starts to heat. If the required room temperature has been reached during the heat-up time, the appliance switches off. It starts again if there is a further heat demand and will continue doing so until the selected heating time has elapsed. This process is repeated daily. The heating time can be adjusted at any time if required by pressing time segments up or down.
5.2 Stopping heating / Frost protection
Turn the temperature selector fully anti-clockwise.
In this setting, frost protection is only ensured if the rocker switch is positioned for “Standard operation”. The heater starts automatically if the room temperature drops below
the frost protection temperature.
5.3 Taking the appliance out of use
Pull the plug from the power socket.
6. Operation CKR 20 S

Temperature selector
Rocker switch stage (Base heating stage)
Rocker switch stage (Quick heating stage)

6.1 Starting heating
Turn the temperature selector clockwise to the required setting.
The temperature is infinitely adjustable. The appliance switches off as soon as the selected room temperature has been reached.
You can use the rocker switch to choose between the following two outputs with matched fan motor speed:
Base heating stage
Set the rocker switch to “I”. Provided that the appliance has been switched on via the temperature selector, it will heat with an output of 1000 W at the slow fan stage.
Note
Never operate the appliance at the standard heating stage
If the room where the appliance has been installed has cooled down severely. f If the room has cooled down severely, switch the appliance to rapid heating stage II in order to ensure normal appliance operation.
Quick heating stage
Set the rocker switch to “II”. Provided that the appliance has been switched on via the temperature selector, it will heat with an output of 2000 W at the quick fan stage.
Select the powerful quick-heating stage if you need to heat up a cold room rapidly to the selected temperature. Afterward, set the rocker switched back to stage “I”.
Once the preselected room temperature has been reached, the appliance switches off. The appliance then starts and stops heating as necessary to keep the room temperature constant.
6.2 Control with external room temperature controller
In rooms larger than 20 m you can operate the appliance with a conventional external room temperature controller.
To do so, turn the temperature selector fully clockwise.
6.3 Stopping heating / Frost protection
Turn the temperature selector fully anti-clockwise and select quick heating stage “II” on the rocker switch.
This position ensures frost protection. The heater starts automatically if the room temperature drops below the frost protection temperature.
6.4 Taking the appliance out of use
Pull the plug from the power socket.
7. Operation CKT 20 S

Temperature selector
Time switch

7.1 Starting heating
The temperature is infinitely adjustable. The appliance switches off as soon as the selected room temperature has been reached.
Turn the temperature selector clockwise to the required setting.
7.2 Adjusting the time switch
With the time switch, the appliance heats with full output and without temperature control.
Turn the time switch selector clockwise to set any number of minutes to count down, from 0 – 60 minutes.
7.3 Stopping heating / Frost protection
Turn the temperature selector fully anti-clockwise and ensure that the time switch is set to “0”.
This position ensures frost protection. The heater starts automatically if the room temperature drops below the frost protection temperature.
7.4 Taking the appliance out of use
Pull the plug from the power socket.

Cleaning, care, and maintenance

The appliance contains no user-serviceable parts.
Clean the appliance when cold with ordinary cleaning products.
Avoid abrasive or corrosive cleaning products.
If a pale brownish discoloration appears on the appliance casing, wipe this off as soon as possible with a damp cloth.
Damage to the appliance and environment
Never spray cleaning spray into the air slot.

Storage

When not in use, keep the appliance in a dry place.

Troubleshooting

If the appliance does not heat, check the temperature set at the appliance and the MCB/fuse in your fuse box.
The appliance has a temperature limiter that shuts the appliance down if it overheats. After the cause has been removed (for example air outlet or inlet apertures covered) and
the appliance has cooled down for a few minutes, the operation starts again.
If you cannot remedy the fault, notify your heating contractor. To facilitate and speed up your inquiry, please provide the serialnumber from the type plate (000000-0000-000000).
