4. Appliance description

The appliance is an electric direct heater only for installation on a wall.

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 expelled 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 electrical connection to the main breaker, the appliance is ready for operation.

5. CNS E Operation

The CNS E is a convection operated space heater with a thermostat and an on/off switch.

5.1 Description of the user interface

» Switch the appliance ON via the switch on the right hand side of the appliance.
» Set the required room temperature via the continuously variable temperature selector (for temperatures see specification chapter).

3D technical drawing of a mechanical component with no visible text or symbols

As soon as the selected room temperature is reached, it constantly maintained at this selected temperature thro 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.

To avoid excessive power consumption when windows are open, you should stop the appliance while venting.

5.2 Frost protection

To disable normal heating but maintain protection against freezing, 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 (45 °F / 7 °C).

5.3 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 prevent adjustment of the selected temperature, push a pin into the hole opposite (see diagram).

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).

5.4 Shutting down

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

6. Cleaning, care and maintenance

WARNING:

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. Failure to do so could result in serious burns, electrocution, serious bodily injury, or death.

If a pale brownish discolouration appears on the appliance casing, wipe this off as soon as possible with a damp cloth. Clean the appliance when cold with ordinary cleaning products. Avoid abrasive or corrosive cleaning products. 8.2 Inst

CAUTION: Fire

Never spray cleaning spray into the air slot. Ensure that no moisture can enter the appliance.

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.

7. What to do if ...

... the appliance does not heat up:

Check the temperature set at the appliance and the circuit breaker 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 appliance 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 (000000-0000-000000).

INSTALLATION

8. Safety

Only qualified contractors should carry out installation, commissioning, maintenance and repair of the appliance.

8.1 General safety instructions

DANGER: Electrocution

If you mount the appliance on the wall, do so in such a way that control equipment cannot be touched by a person in the bath or shower.

CAUTION:

-Only fit the wall mounted appliance to a vertical wall that is temperature-resistant to at least 185 °F / 85 °C.

-Observe the minimum clearances to adjacent object surfaces (for minimum clearances see specification chapter).
- Never install the appliance directly below a wall socket.
-Ensure that the power cable is not in contact with any appliance components.

» Wall mounting bracket (hooked into the appliance)

10. Installation

10.1 Installing the wall mounting bracket

You can use the wall mounting bracket as a template for wall mounting; this ensures the required floor clearance.

» Unhook the wall mounting bracket.
» Place the centred wall mounting bracket level on the ground and mark holes 1 and 2.
» Lift up the wall mounting bracket so that its lower holes match up with the markings you have just made on the installation wall.
» Mark holes 3 and 4 on the installation wall.

1 2 3 4 ① ② 26.07_31_0124

» Drill holes at all four markings. Secure the wall mounting bracket with suitable materials (screws, rawl plugs) depending on the type of wall. With the vertical slots, you can compensate for an offset fi xing hole.

10.2 Appliance installation

» Hook the appliance by its slots in the back of the appliance on to all four tabs of the wall mounting bracket simultaneously.
» Push the appliance to latch it in position.
» Turn the locking bolt in the wall mounting bracket fully clockwise; this locks the appliance in place.
» Push the safety cap onto the locking bolt to prevent it from loosening.

^e 10.4 Power supply

This appliance does not come with an electric cable. Cable must be routed to the unit from a circuit breaker of suitable size.

Ensure the power cable is of a suitable gauge.

10.5 Terminal block

Consult the chart below for the recommended torque amounts on the terminal block screws.

Screw Size (mm)	Min. Torque (N·cm)	Min. Torque (Lbf·in)
M3.5	60-80	5.31-7.08

Using the proper torque specifications to secure wire to the wiring block helps to avoid personal loss or property damage.

DANGER: Electrocution

Carry out all electrical connection and installation work in accordance with all national, state and local building code.

DANGER: Electrocution

Each heater must be wired directly to the circuit breaker panel with the proper size breaker and wire gauge.

DANGER: Electrocution

Do not plug the heater into a wall outlet.

The specified voltage on the nameplate must match the voltage at the circuit breaker panel.
