Before working with the machine
4
4 Before working with the machine
Have the machine installed by your service technician authorised by Winterhalter or dealer. You will find
further information in chapter 22. Follow chapter 17 if the installation location is not free of frost.
Have the machine connected by authorised technicians in accordance with the locally applicable standards
and regulations (water, waste water, electrics). You will find further information in chapters 23 and 24.
Have the machine commissioned by a service technician authorised by Winterhalter. At the same time,
have yourself and your operating personnel trained in how to operate the machine.
4.1 Initial installation
After the machine has been correctly connected to water and electricity, contact your Winterhalter branch
or your dealer in order to request initial installation and training on how to operate the machine.
5 Product description
The UC series dishwashing machines are designed to be used to wash various dishes. The service techni-
cian authorised by Winterhalter does not program the machine's control unit for use of the dishwashing ma-
chine as a “special machine” for a specific application until it is installed. Alternatively, the dishwashing ma-
chine is supplied ready-programmed for a specific application, but can be reprogrammed at any time.
Programming determines whether the machine can be used either as:
a dishwashing machine (if mostly dishes are to be washed), or as
a glasswashing machine (if mostly glasses are to be washed), or as
a bistro dishwashing machine (if dishes and glasses are to be washed), or as
a cutlery rinsing machine (if only cutlery is to be washed).
If the application changes, the service technician authorised by Winterhalter reprograms the control unit and
thus adapts it to your requirements.
Special equipment
1
Cool (only for glass washing machines)
The washing power of the constantly hot tank water ensures hygienic results. At the end of the wash cycle,
the rinse with cold fresh water ensures the glasses are cooled.
The special benefit: the rinse temperature can be increased at any time. You can always at all times whether
you require cold glasses or wish to optimise drying with a hot rinse.
IMPORTANT: The first wash cycles after activation of the function are performed with hot or warm rinse
water.
Requirement: Machine connection to cold water.
Energy
The construction above the machine includes a fan motor and a heat exchanger. After rinsing, the fan motor
draws the moist, warm vapours out of the washing area through the heat exchanger. The cold fresh water
which flows through the heat exchanger for rinsing during the following washing programme condenses the
vapours and is pre-heated. This reduces the energy required to heat the fresh water to the required rinse
temperature. At the same time, the air quality in the kitchen is improved in the long-term since less vapour
(i.e. exhaust) escapes the machine when the machine door is opened.
Requirement: Machine connection to cold water.
UC-S Excellence-i(Plus), UC-M Excellence-i(Plus)
A reverse osmosis module is built into the plinth of these machines. The reverse osmosis module produces
osmosis water for the rinse. The special functions are described in a supplementary manual that comes with
the machines.

terhalter Internet portal.
Identification feature: The text PAY PER WASH on the display.
The special functions of PAY PER WASH are described in a supplementary manual that can be downloaded
from the Winterhalter website: www.winterhalter.biz/manuals.
CONNECTED WASH
Machines with this special equipment can be connected with the Winterhalter Internet portal. After registra-
tion, you can read the various operating data and information about the machine there. The special functions

6 Rinse aid and detergent
Danger
Possible risk of chemical burn
Wear protective clothing, protective gloves and protective goggles when handling chemicals.
When handling chemicals, observe the safety notes and the dosage recommendations on
the packaging.
Caution
Only use products which are suitable for commercial dishwashing machines. Such products
are marked accordingly. We recommend using products developed by Winterhalter. These
products are specially adapted for Winterhalter dishwashing machines.
Do not mix different detergent products as this could result in crystallisation and consequent-
ly cause irreparable damage to the detergent dosing device (6.6).
Do not fill the storage tanks for rinse aid with detergent and vice versa.
6.1 Rinse aid
Rinse aid is required so that the water on the dishes drains off as a thin film and dries quickly after washing.
Rinse aid is dosed into the machine's boiler automatically, either from a storage tank integrated in the ma-
chine or an external storage tank. The rinse aid dosing device is integrated into the machine. The dosing
quantity is set by the service technician authorised by Winterhalter when the machine is installed.
INFO: The rinse aid dosing device is not part of the scope of delivery for all machines.
A display on the screen indicates when integrated storage tanks are empty (11.1). Exter-
nal storage tanks have to be fitted with a suction tube with level control if a display on the
screen is required to show when the filling level drops.
6.2 Detergent
Caution
Do not use products that can create foam (e.g. hand soap, soft soap, manual washing-up liq-
uid). Ensure that these do not enter the machine even during the pre-treatment of the wash
items.
Detergent is required to remove food residue and soiling from the dishes. Detergent can be dosed in the
following ways:
manually as detergent powder.
automatically from an integrated storage tank by an integrated detergent dosing device.
automatically from an external storage tank by and integrated or externally fitted detergent dosing device.
INFO: The detergent dosing device is not part of the scope of delivery for all machines.
6.2.1 Dosing the detergent powder
Pre-dosage
Add the detergent powder in the machine as soon as the start button lights up green. The machine is then
ready for operation (heated up).
UC-S: approx. 30 g
UC-M, UC-L and UC-XL: approx. 50 g
Start a wash cycle immediately afterwards in order to mix the detergent powder with the water.
Adhere to the instructions for dosing on the detergent packaging.
Additional dosage
After 5 wash cycles add approx. 10-15 g of detergent powder in the machine.

6.2.2 Dosing the liquid detergent
The dosing quantity is set by the service technician authorised by Winterhalter when the machine is installed.
A display on the screen indicates when integrated storage tanks are empty (11.1). Exter-
nal storage tanks have to be fitted with a suction tube with level control if a display on the
screen is required to show when the filling level drops.
6.3 Pour in liquid detergent and rinse aid
Caution
When filling make sure that no detergent gets into the rinse aid storage tank, and vice versa.
Opening with white flap: Detergent storage tank
Opening with blue flap: Rinse aid storage tank
Take hold of the lower body panel sides
on the storage tanks and fold them for-
ward
Place funnel (1) in the filler opening.
Place container on the funnel and fill
until the float switch (2) is visible.
Fold lower body panels back
Rinse the funnel in the dishwasher after
use.
6.4 Priming the dosing device
The dosing devices have to be primed if air has entered into the dosing tube due to the storage tanks not
being refilled quickly enough.
For an integrated dosing device proceed as described in chapter 12.
For an external dosing device refer to the equipment documentation.
6.5 Suction tube with level control
Caution
Only use the suction tube with sufficiently stable containers. Narrow and tall containers can
tip if the suction tube is pulled.
Do not place the suction tube for the rinse aid in the detergent container or vice versa.
Do not pull unnecessarily on the suction hose or main power cable, as this may lead to a
defect.
As an option, with your machine you may have one or more suction tubes. The suction tube is already con-
nected to the machine.

Servicing and maintenance
Rinse the suction tube at every container change under running water. Re-
move crystallised detergent residue.
Ensure that both vent holes (a) in the caps are open.
Put the suction tube back into the container. Slide the cap downwards until
the container opening is closed.
6.6 Changing the detergent product
Pay attention to the following when changing the detergent product:
Mixing different detergent products can lead to crystallisation and cause the dosing device to fail.
This is the case even if the new detergent product is from the same manufacturer.
As a rule, a new detergent product means it is also necessary to reset the dosing device.
The entire system, comprising the storage tank, dosing tubes and detergent dosing device, has to be
flushed with water before the new detergent is used.
Have the necessary work carried out by the service technician authorised by Winterhalter so that you
continue to achieve good washing results.
Winterhalter Gastronom GmbH will not accept any liability and all warranty claims will be rendered null and
void in case of failure to comply with this instruction.
If the detergent is dosed from external storage tanks, you can flush the dosing tubes and the detergent dos-
ing device with water yourself:
Procedure:
Warning
When using chemicals, adhere to the safety notes and recommended dosages printed on the
packaging.
Wear protective clothing, protective gloves and protective goggles when handling chemicals.
Do not mix different detergent products.
Remove the suction tube from the storage tank and insert it in a container filled with fresh water.
Flush the dosing tubes and the detergent dosing device with water by repeatedly using the “vent the dos-
ing device” function (see 12). How frequently you do so depends on the length of the dosing tubes.
Insert the suction tube into the storage tank with the new detergent.
Repeatedly use the “vent the dosing device” function to replace the water in the dosing tubes with deter-
gent.

Integrated water softener (optional)
9
7 Integrated water softener (optional)
Softening the tap water prevents the build-up of limescale in the machine and on the dishes. In order for the
integrated water softener to function properly, the salt container must be filled with regeneration salt.
7.1 Entering the water hardness
When the machine is installed, the service technician authorised by Winterhalter measures the water hard-
ness and enters the respective value.
7.2 Lack of salt display
A display on the screen (11.1) indicates when an empty salt container needs to be refilled.
The display disappears after topping up the salt container as soon as approx. 3 wash cycles
have been complete and some of the salt added has dissolved.
7.3 Adding regeneration salt
Caution
Only add regeneration salt to the salt container.
This salt should be fine-grained (max. 0.4-7 mm grain size). Salt tablets are not suitable.
Do not add any chemicals, e.g. detergent or rinse aid. These will inevitably cause damage to
the water softener.
Caution
After filling start a wash cycle.
After filling, immediately start a washing programme in order to rinse off any salt residue.
Otherwise there is a risk of rusting in the filling area.
Open the machine door and re-
move the washing rack from the
machine

of the machine. After the first programme step (figure 4), the self-cleaning programme is interrupted so that
you can remove the filter cylinder and the strainer and clean them (figures 5-15). If you do not follow these
steps, the self-cleaning programme will continue automatically after 30 seconds.
Proceed in accordance with Figures 1 to 30.

10.1.3 Cleaning the inside of the machine
Caution
When performing daily cleaning, make sure that no foreign objects which may rust have been
left in the interior of the machine. These objects can even cause “stainless steel” material to
rust. Rust particles may originate from non-stainless steel dishes, cleaning aids, damaged wire
racks or water pipes with no corrosion protection.
The following materials must not be used for cleaning:
High-pressure cleaner
Detergents containing chlorine or acid
Sponges and wire brushes containing metal
Abrasives or abrasive cleaners
Remove any soiling from the interior of the machine with a brush or a cloth.
Clean the labyrinth below the door.
10.1.4 Cleaning the outside of the machine
Clean the screen with a damp cloth.
Clean the exterior surfaces with a stainless steel cleaner and stainless steel polish.
10.1.5 Checking the external water treatment (if available)
Check whether sufficient regeneration salt has been added.
10.2 Weekly cleaning
Cleaning the rotating wash fields (top and bottom)
Proceed in accordance with Figures C1 to C6.

10.3 Descaling
If the machine is operated with very hard water and without the appropriate water treatment, limescale can
build up in the boiler, in the interior of the machine and in all lines which carry water.
Limescale deposits and the dirt and grease residue they contain represent a hygiene risk, and the limescale
can cause the heating elements to fail. Therefore, it is essential to remove these deposits at regular inter-
vals.
You should have the job of correctly descaling the boiler and all pipes which carry water carried out by a
service technician authorised by Winterhalter.
You can descale the interior of the machine yourself using the descaling programme (14.5.1).
Warning
When using chemicals, adhere to the safety notes and recommended dosages printed on the
packaging.
Wear protective clothing, protective gloves and protective goggles when handling chemicals.
10.4 Maintenance by customer service
We recommend having the machine serviced at least once a year by a service technician authorised by Win-
terhalter. This service should also include having components which are subject to wear or ageing being
checked and replaced as necessary.
Examples of such components:
Water connection hose
Dosing tubes
Door seal
On the electronic control unit you can program the maintenance interval in operating hours and
set the number of remaining operating hours from which point the symbol for maintenance / ser-
vicing is displayed. If necessary, open the cleaning opening in the rotating wash field with a coin
and rinse the rotating wash field with water.
