The following regulations must be observed:
• VDE 0100
• EN 806
• Installation must comply with all statutory regulations, as well as those of the local electricity
and water supply companies.
• The rating plate and technical specifications
• Only intact and appropriate tools must be used
4. Installation
Thoroughly rinse the water supply pipes before installation to remove soiling from the pipes.
1. Using a 12 mm hexagon socket screw key, screw the screw-in nipples according to image
manual into the wall connections as shown in. The seals must be fully screwed into the
thread.
Installing the wall bracket
• The electrical power supply cable may be connected in the upper part. In such case, the
connection will be done according to the description “Electrical connection from above” in
online manual.
• Install the appliance according to image manual.
Installing the appliance
Note: Accessories and surface mounting
Note: Fasten the screw nuts with caution, to avoid damage to the valves or the piping system.
• As shown in the illustration, screw the cold water connection piece with the union nut and
the ½ inch seal onto the cold water connection.
• Screw the hot water connection piece with the union nut and the ½ inch seal onto the hot
water connection.
Installing connection pieces
• Put the water flow reducer “
D” into the hot water connection piece. The O-ring must be
visible.
Note: If necessary, the connecting terminal can be displaced to the upper part of the appliance.
To do this, please follow the instructions in the operating and installation manual available online.
Check that the power supply is switched off prior to electrical connection!
1. Dismantle approximately 6 cm off the connecting cable above the wall outlet (fig. E2). With
the smaller opening ahead, slide the water splash protection sleeve over the connecting
cable so that the sleeve is flush with the wall. This prevents any leaking water from coming
into contact with the electrical leads. It must not become damaged! The protection sleeve
must be used!
2. Open the control panel rightwards.
3. Strip the cables and plug them in the connecting terminals according to the wiring diagram.
The appliance must be earthed.
4. Pull the protective sleeve over the connecting cables until the sleeve fits perfectly in the
recess of the intermediate panel. Adjust the water splash protection sleeve as illustrated and
fix it with the sleeve fixing (A). Reinsert the control panel and lock it on (fig. E3).
5. Place the hood on the appliance and screw in the fastening screw. After that you can slide
on the faceplate from the bottom up to the stop.
Based on the national constitution guidelines a general test certificate concerning the evidence
of applicability of noise behaviour is granted.
Installation site
• Appliance must only be installed in frost-free rooms. Never expose appliance to frost.
• The Appliance must be wall mounted and has to be installed with water connectors down-
ward or alternative transversely with water connections left.
• The appliance complies with protection type IP25 and may therefore be installed in protec-
tion zone 1 according to VDE 0100 part 701.
• In order to avoid thermal losses, the distance between the instantaneous water heater and
the tap connection should be as small as possible.
• The appliance must be accessible for maintenance work.
• Plastic pipes may only be used if they conform to DIN 16893, Series 2.
• The specific resistance of the water must be at least 1100 Ω cm at 15 °C. The specific resist-
ance can be asked for with your water distribution company.
2. Hold the included mounting template according to image manual on the wall, mark the drill
holes according to the template and drill them using a 6 mm drill.
3. Pull down the faceplate and unscrew the main hood screw to open the appliance.
4. Loosen the knurled nut of the wall bracket, remove the wall bracket and screw it on the wall.
Offset tiling or uneven surfaces can be compensated by up to 30 mm with the aid of the
spacers supplied. The spacers are fitted between the wall and the wall bracket.
