1. Operation instructions for the user and the professional

Use of electrical equipment in principle re- quires care to exclude any potential risks from fire, electrical shock or injury. Therefore the unit should only be used as described in these instructions, where any use outside the manu- facturer‘s recommendations can lead to dam- age or injury. The correct match between the heat require

ment of the room and the heating power of the unit must be observed. Before use of the unit, read the entire instruc

tions and follow the information given on proper handling of the unit. These instructions should be kept carefully and handed to any subse- quent user of the unit. Please show them to the engineer performing any repair work.

The CNS is an electric direct heater exclusive- ly for wall installation. It is suitable e.g. for heat- ing a bathroom or as transitional or additional heating for small rooms such as hobby rooms or guest rooms. Series CNS-S After wall mounting and electrical connection via a plug and socket, the unit is ready for use. Series CNS-U After wall mounting and electrical connection via a fixed connection through a junction box (note national regulations), the unit is ready for use. Function The air in the convector is heated by heating element and emerges by natural convection at the top through the air outlet grille (4). The openings in the underside of the unit provide cooling room air Safety device The convector has a protective thermostat (STR) which switches the appliance off on overheating. After eliminating the cause (e.g. covered air outlet or inlet opening), after a cooling down period of a few minutes the unit resumes operation.

The convector is switched on and off via the switch (1) on the right-hand side. The desired room temperature is set via the temperature selector (2) anywhere between around +6°C and +30 °C. As soon as the set room tem- perature has been reached, it is maintained constantly by intermittent heating (the heating power of the unit must correspond at least to the heat requirements of the room). If several heaters are fitted in a room, the temperature setting on each unit may vary. To avoid excessive energy consumption with the windows open, the unit should be switched off during ventilation at the switch ( 1). Frost protection If the unit is used as a frost guard, set the tem

perature selector (2) to the far right stop (*). In this position the thermostat switches the heating on automatically if the room tempera- ture falls to around +6°C. Limiting the thermostat Using the two pins on the back of the switch housing ( 3), the thermostat can be fixed in a particular setting.

C26_07_31_0038 To fix a desired temperature, push pin a into the hole opposite. To limit the temperature adjustment range, set the minimum and maximum values on the selector knob and mark these by inserting pin

into the opposite, slightly offset hole each time.

1.2.1 External room thermostat

If necessary the unit can be operated with a commercial external room thermostat. The temperature selector (2) must be turned to the right stop (MAX). The room thermostat should be located as far as possible from the unit and at least 1.5 m high.

To shut down the unit, move the switch to the OFF position and remove the mains plug from the wall socket (do not pull out the plug using the lead).

The unit should not be operated – in rooms at risk of explosion or re from chemicals, dust, gas or vapour, – in the immediate vicinity of pipes or con- tainers which transport or contain am- mable or explosive substances, – if the minimum distances from adjacent object surfaces are not observed.

• Installation (electrical installation), first op

eration and maintenance of this unit may only be performed by an accredited expert according to these instructions.

• The unit must not be operated if in the same room work is performed such as floor laying, grinding, sealing, cleaning with petrol and care (spray, beeswax) and similar.

• The housing surfaces of the unit and the emerging air are hot during operation (over 80 °C). Risk of burns! Keep small children away from the unit.

• Do not place objects on the unit, lean ob- jects against it or store anything between the heater and the wall (e.g. drying washing). Also do not place in the immediate vicinity of the unit any flammable, combustible or heat-insulating objects or substances such as laundry, blankets, newspapers, containers of beeswax or petrol, spray cans or similar. Risk of explosion! To prevent overheating of the unit, it must not be covered.

For objects of all types e.g. furniture, curtains, hangings or textiles or other flam

• The unit may not be used as a freestanding unit.

• Do not stand on the unit.

• No changes may be made to the unit.

• The unit should never be left in operation accidentally.

• Special care is required if the unit is used in the presence of children, the infirm or animals. Risk of injury!

• If part of the unit is damaged, if the unit has fallen off or is malfunctioning, do not operate.

1.4 Care and maintenance

If the unit housing shows a slight brown discol- ouration it should be cleaned as soon as pos- sible with a damp cloth and hot water: When the appliance is cold it can be cleaned with normal cleaning agents. Avoid scouring or aggressive cleaning agents. Moisture must not penetrate the unit. Do not spray cleaning spray into the air slots.

2.2 Provisions and specica-

tion The unit should not be operated – in rooms at risk of explosion or re from chemicals, dust, gas or vapour, – in the immediate vicinity of pipes or con- tainers which transport or contain am- mable or explosive substances, – if the minimum distances from adjacent object surfaces are not observed. In workshops or other rooms in which ex- haust gases, oil or petrol vapours etc. occur or where solvents and chemicals are used, persistent odour problems and where appli- cable contamination can occur.

• The unit may only be fitted to a vertical wall, temperature-resistant up to at least 80 °C.

• Minimum distances from adjacent object surfaces must be observed.

• All electrical connection and installation work must be performed to VDE regula

tions (0100), the regulations of a competent utility company and the corresponding na- tional and regional regulations. For regular maintenance we recommend checking the control and adjustment elements. At the latest 10 years after first use, the safety, control and adjustment elements should be checked by an expert.

• The unit must not be mounted directly be- low a wall socket.

• If the unit is permanently connected to an AC network (junction box) an isolation distance of at least 3mm is required on all poles for isolation from the network. For this circuit breakers, LS switches, fuses etc. can be used. Installation with permanent connection ca- bles is not permitted.

• The rating plate must be observed. The rat- ed voltage must correspond to the nominal voltage.

• On installation of the heater in rooms with a bath and/or shower, the protection area to VDE 0100 part 701 as specified on the unit rating plate must be observed.

• The unit must be mounted such that the switch and control units are out of reach of a person in the bath or shower.

• The mains connection cable may only be replaced with original Stiebel Eltron spare parts by experts.

The wall bracket should be used as a template for fixing the appliance to the wall. It also helps to keep the necessary ground clearance. To at

tach the unit proceed as follows: I Place the wall bracket (5) holding the centre point horizontally on the ground and mark the holes a and d on the assembly wall; II Raise the wall bracket so that the ho- les b in the wall bracket coincide with the marks just made on the assembly wall; Mark holes c and d on the wall bracket on the assembly wall; At all four markings drill holes and attach the wall bracket to the wall using suitable fixing materials (wall plugs and screws) de

pendig on the type of wall. The vertical slots allow adjustment for an offset in the fixing holes.

The convector is mounted by attaching the slots on the rear simultaneously to the four tabs of the wall bracket pressing down to lock. The closing bolt (

6) of the wall bracket is then

turned clockwise to the stop, locking the fixing. To remove the convector, unscrew the locking bolt and lift the unit slightly, pulling it forwards and out of the bracket.

2.4 Electrical connection

The required electrical connection is AC 230V ~ 50 Hz. For fixed connection, an earth socket or junc

tion box should be installed at a distance of at least 10 cm to the side of the heater.

Explain to the user how the unit functions. Draw his attention in particular to the safety instructions. Give the user these operating and usage in- structions. Chechk that . . . . . . the ON/OFF switch is turned on. . . . in your fuse box, the corresponding fuse is intact or whether the breaker has tripped. Eliminate cause! If the heater still does not warm up, call an engineer! Check whether it is covered, so it could have overheated (e.g. covered air outlet or inlet opening). Eliminate cause! If it does not warm up again after a few minutes‘ cooling down period, call an engineer! Read the type (Typ) and number (Nr.) from the rating plate (8) on the unit and tell customer service!
