The heater must be properly installed before it is used.

DANGER Electrocution

- Before cleaning, make sure the power has been turned off at the circuit breaker panel and that the heating element of the heater is cool.

DANGER Fire

Never operate this appliance ...

• if the minimum clearances to adjacent object surfaces are not maintained, for example to furniture, net curtains, curtains, textiles or other flammable materials (for minimum clearances, see "specification/dimensions and minimum clearances").
• in rooms where the appliance is at risk from fire or explosion as a result of chemicals, dust, gases or vapors.
• in the direct proximity of pipes or containers that carry or contain flammable or explosive materials.
• if work such as laying cables, grinding or sealing is carried out in the installation room.
• if sprays, floor polish or similar products containing gasoline are used. Vent the room sufficiently before heating.
• if an appliance component is damaged, the appliance has fallen over or already had a fault.
• outdoors.

DANGER Fire

Never place any flammable, combustible or insulating objects or materials, such as laundry, blankets, magazines, containers with floor polish or gasoline, spray cans or similar on the appliance or in direct proximity to it.

WARNING Fire

Ensure that no foreign bodies enter the ventilation air and extract air apertures. This could result in electric shock or fire or in damage to the appliance.

WARNING Fire

To prevent fires ensure that the air inlets and outlets are never blocked. Never position the appliance on soft surfaces, such as a bed, as this could result in the apertures becoming blocked.

DANGER Overheating

The appliance could continue to heat the room unchecked if it is operated on a time switch. Ensure constant supervision if the appliance is used in a small room and the persons within that room cannot leave the room on their own.

WARNING Injury

Where children or persons with limited physical, sensory or mental capabilities are to be allowed to control this appliance, ensure that this will only happen under supervision or after appropriate instructions by a person responsible for their safety.

Children should be supervised to ensure that they never play with the appliance.

4. 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 out of plastic. The controls are located on the right 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.

4.1 Control with external room temp. controller

(Only applicable for: CK)

In rooms larger than 215 ft ^2 (20 m ^2 ) you can operate the appliance with a conventional wall mounted room thermostat.

▶ To do so, turn the temperature selector fully clockwise.
▶ Control the temperature by using the wall thermostat.

5. Operation CK 15 E / CK 20 E

1 0 26_07_31_0211

1 Temperature selector

5.1 Starting heating

The temperature is infinitely adjustable. The appliance stops heating as soon as the selected room temperature has been reached.

▶ Turn the temperature selector clockwise to the required setting.

5.2 Stopping heating / frost protection

To ensure frost protection, the power switch must be in the on position.

▶ Turn the temperature selector fully counter clockwise.

This position ensures frost protection. The heater starts automatically if the room temperature drops below the frost protection temperature.

6. Operation CKT 15 E / CKT 20 E

1 Temperature selector
2 Timer

6.1 Starting heating

The temperature is infinitely adjustable. The appliance stops heating as soon as the selected room temperature has been reached.

▶ Turn the temperature selector clockwise to the required setting.

6.2 Adjusting the time switch

With the time switch, the appliance heats with full output and without temperature control.

▶ Turn the Timer clockwise to set any number of minutes to count down from 0 - 60 minutes.

6.3 Stopping heating / frost protection

This position ensures frost protection. The heater starts automatically if the room temperature drops below the frost protection temperature.

▶ Turn the temperature selector fully counter clockwise and ensure that the time switch is set to "0".

7. 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 the environment Never spray cleaning spray into the air slot.

8. Storage

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

9. Troubleshooting

If the appliance does not heat, check the temperature set at the appliance and the circuit breacker.

The appliance has a safety high limit 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, operation starts again.

If you cannot remedy the fault, notify the contractor who installed the appliance. To facilitate and speed up your enquiry, please provide the serial number from the type plate (000000-0000-000000).
