Electrical connection
•
Do not open the appliance housing for installation or power connection.
•
The heater is connected with the supplied plug connector to a power mains socket to be
provided at the site of installation. If the supplied connecting cable is not long enough, it can be
replaced with a H05VV-F 3x1.0mm² cable. Direct connection to a fixed line is only permissible
up to a cross-section of 1.5mm² (e.g. NYM-J 3x1.5mm²).
•
At the site of installation, an all-pole circuit breaker or disconnect device with a contact gap of
min. 3mm must be installed in the fixed electrical system (observe applicable regulations and
standards).
Assembly sequence
• Deenergise the power supply line to be connected to the appliance.
• Connect the supplied cable wires to L (brown), N (blue) and PE (green/yellow). For bathroom
installation in safety zone 2 (see Fig.3), the connecting point (power socket, etc.) provided at the
site must also conform to IP24. For possible connection layouts (e.g. in conjunction with room
thermostat), see wiring diagrams below.
Wall installation
• When installing the appliance vertically, ensure that the plug connector (Fig.1, item 5) is at the
top. For horizontal installation, it must be to the left (seen from the front of the appliance) (see
arrows in Fig.1), as protection rating IP24 can otherwise not be guaranteed.
• Insert the appliance with the lower (fixed) hooks into the lower securing tabs (Fig.1, item 7) of
the wall bracket. Check carefully whether the hooks are fully inserted!
• Tilt the top of the appliance away from the wall by approx. 10 to 15cm and insert the mains
cable.
Ceiling installation
• Work in teams of minimum two fitters.
• Lift the appliance and connect the plug connector of the supply line (Fig.1, item 5) to the heater.
• Insert the appliance with the lower hooks into the lower (fixed) tabs (Fig.1, item 7) of the wall
bracket. Check carefully whether the hooks are fully inserted!
• During the subsequent installation work, keep the appliance pushed against the lower (fixed)
tabs to ensure that it does not become dislodged.
Wall and ceiling installation
• During the subsequent installation work, press the appliance against the foam blocks at the rear
(Fig.1, item 6) towards the wall and secure the upper (spring-loaded) tabs (Fig.1, item 3) using a
5mm hex screwdriver. Tighten the screws to the stop. Ensure that the hooks are not caught on
edge and are fully inserted into the tabs.
• Check carefully whether the hooks are fully inserted in the tabs. If this is not the case, hold the
appliance firmly so that it cannot fall, loosen the upper tabs slightly and press them down and/or
press down the appliance to engage the hooks properly. Tighten the upper tabs and check the
hooks for proper insertion.
• Place the supplied plastic caps on the screw heads.
