Installation

19 Installation
Instructions for the service technician authorised by Winterhalter or dealer:
 Adhere to the connection diagram.
 The location for installation must be frost-proof so that the water carrying systems do not freeze.
 Align the machine using a spirit level.
 Cancel out any unevenness of the floor using the adjustable machine legs. Placement on three feet is
possible if the machine is installed below a worktop.
 When opening the machine door, water vapour escapes. This vapour may cause wood to swell. If
furniture adjacent to the machine is made of wood, a steam protection kit must be installed. The same
applies if the machine is installed underneath a wooden work surface.

20 Water connection

Notes for the plumber:
 Adhere to the connection diagram with specifications for water inlet temperature and water pressure.
 Connect the machine to drinking water.
 Install a main stop cock near to the machine, in an easily accessible position in the water supply line.
 It must not be behind the machine.
 Water safety must be ensured in compliance with EN 61770. Accordingly, the machine can be connected
directly to the fresh water pipe without the intervention of any additional protection device.
 Use the supply hose and fine filter located in the dishwashing machine for the water supply. The fine filter
prevents particles from the water supply from penetrating into the dishwashing machine and causing rust
on the cutlery and in the dishwashing machine.
 Check that the connections do not leak. The supply hose must not be shortened or damaged.
Old, pre-existing hoses must not be used again.
 Use the flexible drain pipe located in the dishwashing machine for the water drain. The drain pipe must
not be shortened or damaged.
 The dishwashing machine is equipped with a drain pump. The maximum pump height can be found in the
connection diagram.
 If the water hardness is more than 3°d total hardness (GH), we recommend connecting a water treatment
unit upstream to prevent build-up of limescale in the machine and in order to achieve optimum cleaning
and drying results. The service technician authorised by Winterhalter will be happy to offer advice.

21 Electrical connection

Notes for the electrician:
DANGER! Risk of fatal injury due to live components.
Disconnect the machine from the mains and check that machine is de-energised.
The machine and its associated ancillaries must be connected by an electrical contractor
Danger
authorised by the responsible power company, in accordance with locally applicable
standards and regulations.
 Adhere to the connection diagram.
 Adhere to the rating plate and circuit diagram.
 Check that all electrical protection systems are fully functional.
 Connect the machine to a protective circuit which has been installed and tested in accordance with the
relevant regulations.
 The machine must be connected electrically in compliance with the data on the rating plate.
 Fuse the electrical connection of the machine as a separately fused circuit, as part of the on-site system,
using slow-blowing fuses or circuit breakers, in accordance with the total connected load (see rating
plate).
 In the electric supply line, install a universal current sensitive residual current circuit breaker class B with
a tripping current of 30 mA (DIN VDE 0664) as a frequency inverter is located in the machine.
 The machine connection (mains connection cable) should preferably be installed as a fixed connection.
 When the machine must be permanently connected (without a plug), a mains disconnector with all-pole
separation from the network must be installed. The mains disconnector switch must have a contact
opening width of at least 3 mm, and must also be lockable in the neutral position.
