Laying an electric convector in a bathroom

The electric heating of the bathroom poses security problems. Serious accidents can occur with devices that do not meet safety standards. Comply with those defined by the Technical Union of Electricity (U.T.E.). The radiator fan (convector) posed here, presents all the necessary security guarantees. Suspended on the wall in volume 3 of the bathroom (more than 60 cm from the bath), it is here connected to a ground socket called "comfort", allowed only in this volume 3 of the bathroom.

  • Pencil
  • Bubble level
  • Screwdriver
  • Drill

Steps

  1. Lay the metal wall bracket against the wall
  2. Laying the electric convector

1. A simple convector is an electrical appliance that heats resistances on which the coldest air at the bottom of the room goes upwards. This air is thus heated and then diffuses into the room that it heats up. This system often makes it called "toaster" because it works on the same principle as the home appliance solicited at breakfast. The addition of a fan provides superior comfort since it precipitates the brazing of the air in the room whose cycles of passage on the resistances of the device are renewed much more quickly.

2. Drill the partition with a hole saw and connect the conductors to the socket base. In a bathroom, the electrical installation is most often built-in and the drivers must be placed under waterproof insulated ducts. In any case, use a socket with a ground connection (yellow and green two-color wire). This socket, like the radiator, must be located outside the volume 2 of protection.

3. Carefully screw the base box of the recessed socket.
The conductors must have a sufficient section: 2.5 mm2.
Be sure to connect the ground wire to a grounded outlet and never to a water inlet or outlet pipe.
If the installation is mounted in apparent duct, please ensure that the connection between the duct and the base is perfectly sealed. Preferably choose a comfort type plug with cell plugs.

4. Place the metal wall bracket against the wall. With level and pencil, you will have identified its horizontality. Mark the location of the holes to be drilled and attach the bracket with dowels (if necessary) and screws supplied with the unit.

Laying the electric convector

Hang the radiator

Hang the radiator

1. Hang the fan heater on the protruding end of the wall bracket by holding it down. Its formwork protects it from splashing water. The unit blows warm air through the low rack. So do not put it too high to enjoy the warm air that comes out.

2. The appliance is equipped with a thermostat: the indicator light comes on when the convector starts and goes out as soon as the chosen temperature is reached. On this model, the maximum temperature is 30° C (thermostat 5). Set to minimum (1), the thermostat keeps the room above zero (frost free). Remember to unplug the unit when it is not in use (in good weather) to prevent it from remaining energized, which happens when the thermostat is set to the point (off).

3. As a general rule, convectors, when class II, must not be connected via a plug in a socket but be directly connected by dominoes on conductors (neutral and phase) rigid camouflaged directly by a cover with low footprint for the arrival of the wire of the apparatus. This category does not require a ground connection. But the convector posed here is class I. This authorizes the editing we have done.
