3 Installation and connection
Installation and connection of the washer to the customer’s water inlet, waste water
drainage and electricity connections are to be carried out in accordance with national
and local criteria by qualified engineers.
Check for completeness:
After unpacking the machine, first check the delivery against the delivery note to ensure that it is complete,
and inspect for damage that may have occurred during transportation. Immediately report any damage to the
carrier, the insurance company and the manufacturer.
Setting up and alignment
If machine is installed with accessible back side, back panel is absolutely necessary.
When setting up the machine, remember that the machine gives off water vapour during
operation (e.g. when you open the door). Protect adjacent wooden furniture to prevent it
absorbing moisture and swelling up.
Protect the washer against frost. Systems that carry water can be damaged if they freeze.
Before starting installation, use a spirit level to check that the system is totally horizontal. Adjust the
machine’s feet to compensate for any unevenness of the floor.
Connection to the water supply:
Note all the information on the enclosed connection diagram!
For the machine to work correctly, the required water pressure and flow rate must be
guaranteed at all times.
•Fit a main stop valve in the water inlet near the washer and in an easily accessible position. It must
not be located behind the washer.
•The washer has been tested by the DGVW (German Association for the Gas and Water Industry), and
was designed and constructed in accordance with DGVW guidelines. It can be connected directly to
the fresh water inlet without the need for further safety devices.
•Use the feed pipe and fine filter in the glasswasher for the water feed. Check that there are no leaks at
the connections. The feed pipe may not be shortened or damaged
•Use the flexible drain pipe in the dishwasher to drain the water. The drain pipe may not be shortened
or damaged.
•Installation of a water treatment system (if not already integrated into the machine) is recommended if
the water hardness exceeds 3°d. This will guarantee optimum washing results. The Winterhalter
customer service department will be happy to advise on a suitable system.
•The washer is equipped with a drain pump. The maximum pump-out head is shown in the connection
diagram.

89007311 5
Connection to the power supply:
Have the electric installation of the washer and the auxiliary devices belonging to it carried out
only by a specialist firm of electricians approved by the responsible electricity board in
accordance with the norms.
Observe the technical connection regulations.
Before commissioning the washer, check that all electrical protection systems are working
correctly.
Caution! The machine is only to be considered free from voltage when the mains
disconnecting switch (mains switch) provided by the customer is switched off.
•The total load of the washer is shown on the machine’s rating plate.
•The electrical connection of the washer is to be fused by the customer with time-lag fuses or circuit
breaker according to wattage (see machine rating plate). No other consumers may be fused with the
washer.
•Install a mains disconnecting device (mains or inspection switch) and a fault current breaker (release
current 30mA) in the electrical feeder according to regulations. These switches must switch off all-
poles and have at least 3 mm contact distance. The place of installation must be near the washer and
easily accessible.
•Connect the washer to the customer’s equipotential bonding system. The connecting screw is located
in the machine base.
If the machine is mounted on a base, the base has to be connected to the equipotential bonding
system of the machine.
•The protective conductor (PE) is yellow-green, the neutral conductor (N) is blue and the live wires (L1,
L2, L3) are black or brown.
Connecting cable
The connecting cable may only be changed or replaced by the manufacturer, its customer service
representative or a similarly qualified person. Use an H07 RN-F type cable or equivalent.

Connecting dosing units not made by Winterhalter Gastronom GmbH
A connection for dosing units not made by Winterhalter Gastronom GmbH is found in the machine base. This
connection is marked on the circuit diagram. If needed, a description of connection possibilities can be
ordered.
Final tasks:
The washer must be connected to all services (electricity supply and to the fresh water and waste water
systems), prior to testing the machine & installation
Commissioning (initial washing ) is carried out by a Winterhalter service engineer, who also trains the
operator in how to use the washer.
4 Commissioning
Once the washer is connected correctly to the customer's power supply and water inlet, contact the
Winterhalter works representative with responsibility for the location to arrange commissioning and
instruction in use of the dishwasher.

5 Points to note when washing glasses
Drinking glasses can be cleaned hygienically, quickly and easily. Note the following
important points to keep your glasses in good condition for as long as possible:
Points to note when buying glasses
•Any indentations in the base of the glass should be as shallow as possible.
•The glasses should not have beading around the rim since a heavy rim will prevent the film of water
draining out fully after washing.
•Thick bases (e.g. on wheat beer glasses) cool down very slowly and are more likely to break.
•Very tall, narrow glasses are always harder to wash than glasses of normal height.
Points to note concerning glass racks
•Winterhalter glass racks are designed for washing glasses in a slightly tilted position, which increases
the rinsing effect and allows the water to drain out of indentations in the base more easily.
•Glass racks are made from plastic or plastic-coated wire to prevent damage to the glasses.
•Wire glass racks must not be damaged in any way. The rack should be replaced if the plastic coating
is damaged.
Points to note concerning glasswashers
•Do not wash glasses in a normal dishwasher. The higher temperatures inside a dishwasher will
damage the glass over time.
•Winterhalter Gastronom recommends the following temperatures for washing glasses:
Washing: approx. 60°C
Rinsing: approx. 65°C
•For hygiene reasons, never clean ashtrays in the glasswasher!
How to avoid broken glasses
•Do not polish glasses after washing. This is unhygienic and the mechanical pressure places stress on
the glass.
•Do not cool glasses quickly after washing (e.g. by placing them in cold water or ice). Rinsing with cold
water inside the machine also places stress on the glass.
•Store clean glasses in closed cabinets. Do not store them face down to prevent damage to the rim and
to allow the inside of the glass to dry out completely.
•Do not stack glasses during storage.

89007311 7
Preventing odours
•Use odour-free detergents and rinse aids. We recommend that you use our own products – detergent
and rinse aid.
•Do not store glasses in areas used for baking, frying or roasting.
•Store clean glasses in closed cabinets. Do not store them face down to prevent damage to the rim and
to allow the inside of the glass to dry out completely.
•Do not hang clean glasses from racks over the bar since tobacco smoke can contaminate the inside
of the glasses.
•Do not stand glasses on bar towels, etc, to dry. After washing, remove the rack from the machine and
leave on the bar to allow the glasses to dry in the rack. We recommend the purchase of a second rack
so that the next rack can be filled while the first is being washed.
What to do if glasses are spotted, streaked or dull
•Call in the experts! Have your machine checked out by a Winterhalter customer service engineer.
The wash water
•The water should be pre-treated to prevent mineral and limescale deposits building up on glasses.
•Your water should be tested to determine the correct water treatment for your system. We will be
pleased to help you with this and can also supply suitable water treatment systems.
Preparing the glasses for use
•Before your wash your glasses in the machine for the first time, you should first clean them thoroughly
to remove the protective film applied at the factory.
•This initial cleaning process can be carried out in the machine. Add approx. 50 – 60 ml Winterhalter
detergent directly to the heated wash water and wash the glasses three times.
Attention: Do not put your hands into the wash water. The detergent is extremely alkaline.
Then leave the glasses to dry outside the machine.

6.2 How the glasswasher works
When the machine is switched on, the boiler and tank fill up and are heated to operating temperature. The
programme button (6) is lit red during the heating up phase.
As soon as the target temperatures are reached (tank: approx. 60°C, boiler: approx. 65°C), the washer is
ready for operation. The programme button (6) then lights up green.
The machine is operated using fully-automatic programmes. These consist of three steps: washing, draining
and rinsing. The programme button (6) is lit blue during the programme.
Integral dosing pumps dose the rinse aid and detergent from storage tanks behind the front panel.
Washing: The wash pump pumps the wash water from the tank onto the glasses via the wash arms and
jets. As the wash water circulates, it passes constantly through a filter system where it is cleaned.
Draining: After washing, there is a brief pause to allow the wash water to drain off the glasses.
Rinsing: In the final step of the programme, the cleaned glasses are rinsed with fresh hot water to remove
any detergent residues and to heat up the glasses for optimum drying outside the machine. The rinsing
water also replaces the wash water.
Do not open the door while the programme is running. There is a risk of hot water spraying
out of the machine.
Do not place anything on the open door.
6.3 Wash programmes
The dishwasher has several different wash programmes which are selected using the operating panel.
Programme (button) Description
Normal programme (6) For normal soiled glasses
Medium drying time
Short programme (10) For lightly soiled glasses
Short/no drying time
Programmes with reversible rinse
temperature (11) (optional) For washing dishes
Programme duration: according to selected wash programme
Tank drainage / self-cleaning (2)
Cleaning of the machine:
•Circulation of the wash water inside the wash chamber
•Pumping out the wash water
•Flushing out the wash chamber with fresh hot water
•Pumping out the used fresh water.
The washer switches off automatically when the cleaning
programme is finished.

7 Before washing
Turn water stop valve to open position.
Switch on the mains disconnecting device (mains switch) provided by the customer.
Checking the filter system:
Open the door.
Check that the filter cartridge and flat filter are inserted correctly.
Close the door.
Switch on machine:
Press On/Off switch (1), heating up phase begins.
The programme button (6) is lit red: the boiler and tank are filling and heating up.
Adding rinse aid and detergent:
Only use detergent and rinse aid which are suitable for commercial washers. Do not use
normal washing-up liquid. This leads to large amounts of foam building up in the
washer.
We recommend the products developed by Winterhalter Gastronom. These are
specially developed to suit Winterhalter Gastronom washers.
Irritant: Detergents for commercial glasswashers irritate the skin. Always follow the
instructions on the packaging and drums.

89007311 11
Do not mix different detergent products, since this could cause the dosing pump to
break down due to crystallisation (see Maintenance and care).
If DOS is displayed on the machine operating panel, check the level of detergent and
rinse aid.
Optional extra: an acoustic signal indicates that you have to top up the machine with
detergent or rinse aid.
To do this fold the lower panelling forwards.
The storage tanks are identified with “detergent” and “rinse aid”.
When filling, make sure that no detergent goes into the rinse aid container and
vice versa.
Then fold back the lower panelling.
The programme button (6) is lit green: The tank and boiler have reached their target
temperatures.
The machine is now ready for operation.
Adding regenerating salt *:
* Only for machines with an integral water softener
The salt container inside the machine must be filled with regenerating salt when the
symbol lights up on the operating panel1.
You can do this while the machine is on: you do not have to switch off the machine or
drain the water.
Open the screw cap on the salt container, insert the funnel into the filler opening and
add three bags of Winterhalter special salt (= 1.5 kg).
Remove the funnel and remove any salt residues from around the filler opening.
Replace the screw cap, making sure that the lid is not tilted.
Then perform a washing program immediately to flush out any salt residues. Otherwise
there is a risk of rust forming in the filling area.
Only add regenerating salt to the salt tank!
The salt used should be very fine (max. grain size 5 – 7 mm). Salt tablets are not
suitable.
Do not add any other chemicals, such as detergent or rinse aid. These will cause
damage to the machine.
1Note:
If the machine does not have an integral water softener and this symbol lights up, the connected external
water treatment system is exhausted and must be regenerated. Follow the instructions in the documentation
supplied with the water treatment system.

8 Washing
Observe the following when loading the rack:
•Tip out drink residues (not into the machine).
•Remove paper residues.
•Rinse off any ash with water.
•Load glasses face down.
•Leave a gap between the glasses so that they do not rub against one another. This will prevent the
glasses becoming scratched.
•For tall glasses, use a rack with suitable divisions that will hold the glasses in a stable position.
8.1 Washing with the normal programme
Push the full wash rack into the machine and close the door.
Press programme button (6). The programme button is lit blue while the programme is
running.
The programme button (6) is flashing green when the programme has ended and the
door has not yet been opened. As soon as the door of the machine is opened, the
flashing stops and the programme button 6 switches to a continuous green light.
The flashing programme button (6) indicates that the wash programme is complete and the door has not yet
been opened.
If the flashing disturbs you, the machine control system can be adjusted by an authorised service engineer to
prevent key 6 from emitting the flashing green light.
Open the door, tilt the wash rack forward slightly to allow any remaining water to drain
off the glass bases.
Pull the wash rack out and place it on the bar, for example. Close the door or wash the
next rack.
The intrinsic heat of the glasses and the effect of the rinse aid added to the rinse water combine to quickly
dry the glasses with a bright and shiny finish. To allow the glasses to dry inside, they should be placed face
up in a closed cabinet. Do not stack the glasses, otherwise they might break.
Do not dry recently cleaned glasses with a towel to avoid spreading bacteria and germs.

89007311 13

89007311 15
10 Maintenance and care
The washer should be regularly cleaned to ensure that it remains reliable and in good working order for
many years to come.
In addition to daily cleaning, we recommend that you have the washer serviced at least twice a year by a
Winterhalter service engineer.
Do not spray the machine or direct vicinity (walls and floor) with a water hose, steam jet or high-
pressure cleaner.
When cleaning the floor, take care to avoid flooding the substructure of the machine, in order to
prevent the uncontrolled entry of water.
10.1 Every day after washing
Remove the filter cartridge, clean it under running water and reinsert it.
If the flat filter is very dirty:
Remove the bottom wash trays and rinse them with water.
The endcaps of the wash trays are removeable.
Check, if the wash jets are clean.
Remove the flat filter with the filter cartridge and clean it under running water.
Use a brush to remove any deposits inside the machine.
Remove the bottom wash trays and rinse them with water during cleaning, make sure
that no rusting foreign bodies remain inside the washer. This can cause the interior to
rust. The foreign bodies may come from non-stainless steel items washed, cleaning
aids, damaged wire racks or from supply lines which have not been rust-proofed.
Reinsert the flat filter with the filter cartridge.
Reinsert the bottom wash trays.

16 89007272
Clean the outer walls of the washer with cleaning products for high grade stainless steel.
We recommend the use of Winterhalter Gastronom stainless steel cleaning products.
Open the door slightly into the vent position. This will allow the interior to dry more
easily, which is important for long-lasting protection against corrosion – even for
stainless steel.
10.2 As required
Check the required FI-residual current operated device for faults regularly according to
the regulations by pressing the test button.
Descaling
Machines that are operated in hard water areas and do not have an integral water softener or are not
connected to an external water treatment system must be descaled from time to time. There are descaling
agents specially designed for commercial washers available for this purpose.
Warning: Descaling agents for commercial washers cause corrosion. Always follow the
instructions for use and safety instructions on the packaging and drums.
Changing the detergent type.
If changing to a different detergent type (even one by the same manufacturer), you must rinse the suction
and pressure hoses with fresh water before connecting the new detergent container.
Otherwise, the mixing of different types of detergent will cause crystallisation, which may result in a
breakdown of the dosing pump.
Failure to observe this condition will invalidate the guarantee and product liability claims vis-à-vis
Winterhalter Gastronom GmbH.
