1 Purpose
The Winterhalter Gastronom GS 310 cutlery rinsing machine may only be used to rinse cleaned cutlery.
The cutlery must be brought into a thoroughly hygienic condition before rinsing in the GS 310 (for example,
by washing it in a dishwasher).
Rinsing in the GS 310 cleans salts and other residues from water off of the cutlery so that it can dry without
spots and needs no more polishing.
The GS 310 cutlery rinsing machine may not be used to clean cutlery.
Alterations of the design or intended purpose of the GS 310 cutlery rinsing machine undertaken without the
written permission of Winterhalter Gastronom GmbH shall cause the warranty and product liability to termi-
nate.
If damage should occur to the GS 310 cutlery rinsing machine due to non-observance of these instructions,
no warranty claim may be brought against Winterhalter Gastronom GmbH.
In the rest of these operating instruction the GS 310 cutlery rinsing machine will simply be referred to as
"machine" in order to make the text easier to understand.
2 Safety tips
Do not use the machine until after you have read and understood the operating instructions. Let Winterhalter
customer service tell you how to use and work with the machine.
The symbols are used:

3 Before using the machine
Before you use the machine in your work, it must be connected on your premises by trained specialists in
conformance with locally effective regulations and then set in operation by the Winterhalter customer service.
3.1 Setup and hookup
Setting up and hooking up the machine to the customer's supply lines and outlets must
be performed in conformance with specific local and national circumstances by ap-
proved fitters.
Completeness check:
After unpacking the machine, first check the delivery against the packing slip to see that it is complete and
has suffered no damage during transportation. Inform the haulage company, the insurance company and the
manufacturer immediately of any damages.
Setting up and aligning the machine
Before beginning installation, use a water level to align the machine horizontally. Use the machine's height-
adjustable feet to even out any irregularities in the floor.
Put the machine without any back paneling up against a wall.
Please note that water vapor escapes from the machine when it is running (for instance, when
the door is opened). Any wooden furniture nearby must be shielded to keep it from swelling.
Do not expose the machine to freezing temperatures. Freezing can damage running water
systems damaged.
Sanitary installations:
Please observe carefully the information in the attached connection diagram!
Make sure that the water pressure and flow capacity demanded by the connection diagram are
present so that the machine will function properly.
•Install an easily accessible main shutoff valve in the water supply line near the machine. It may not
be located behind the machine.
•The machine is DVGW and WRC approved, or designed and built according to DVGW and WRC
guidelines. It can be connected to the fresh water supply line without any safety device in between.
•For the cutlery to dry without spots, the water must be kept as free as possible of salts and minerals.
Its conductivity must be less than 50 µS/cm. The best method of water treatment depends on the qual-
ity of the local water supply. In most cases, however, it will be necessary to desalinate the input water.
Winterhalter will be glad to help you choose a suitable water treatment unit.
•Use the hose and the fine filter in the machine to connect it. The fine filter keeps particles from the
water supply line from getting into the machine and causing extraneous rust to form on the cutlery or
the machine itself.
•The machine is equipped with a drain pump. The maximum draining capacity is found on the connec-
tion diagram.

89008157 5
Electrical installation:
Only allow a professional electrical firm approved by the responsible energy supply
company install the electrical devices and accessories in conformance with standards.
In the process, the Technical Connection Regulations (TAB) must be observed.
All electrical safety systems must be checked before the machine is started.
Attention! The machine must be considered live until the customer's main switch has
been switched off.
The electrician must take note of the following:
•The total connected load of the machine is stated on the rating plate.
•Safeguard the electrical connection of the machine with delayed-action fuses or automatic fuses in
conformance with the total connected load (see rating plate). Do not use the machine to safeguard
any other electric power consumers.
•as required by regulations, install a main or on-off switch, as well as an FI safety switch in the electri-
cal supply line. All poles of this switch must respond when it is switched off and it must be at least 3
mm between contacts. It must be installed near the machine and be easily accessible.
•Connect the machine to your potential equalization system. The screw for this connection is located in
the machine's base.
If you set up the machine on a supporting stand, the potential equalization system must be put be-
tween the machine and the stand.
•The protective conductor (PE) is yellow-green, the neutral wire (N) is blue and the wires conducting
the electricity (L1, L2, L3) are black or brown.
Connecting the machine
Only the manufacturer, its customer service representative or a similarly qualified person may make changes
or replacements.
Final work:
The machine must be entirely connected to the electrical power mains and the fresh water supply and waste
water drain system. The electrical safety system must be tested and fully functional.
A Winterhalter customer service technical performs the initial start-up. In the process, the operator of the
machine is instructed in how the machine works.
3.2 Initial start-up
After the machine has been connected to your supply lines according to regulations, contact the Winterhalter
agent responsible for your locality in order to perform the initial start-up and be instructed in how to run the
machine.

4 Good things to know about rinsing cutlery
Water treatment
In order for the cutlery to dry without spots, the water must be as free as possible of minerals and salts. Its
conductivity must be less than 50 µS/cm.
For this reason, it is absolutely necessary to hook up a water treatment unit in front of the machine. We rec-
ommend our Winterhalter VE 15 or VE 20 full desalination unit, or the RoMatik reverse osmosis unit. The
optimum method of water treatment depends on the quality of the water in your locality.
Winterhalter will be happy to help you choose the right water treatment unit for your requirements.
Rinse aid
We recommend using our "Gastronom-Klarspüler S" rinse aid.
The amount of rinse aid is automatically determined by the built-in dispensing unit. It needs about 0.9 ml per
rinse cycle (if you use Winterhalter rinse aid).
Customer service has to set the dispensing speed, since this requires access to electrically conductive
parts.
Be sure that the rinse aid reserve container never empties entirely. Top it up with rinse aid as soon as "DOS"
lights up on the machine's operating panel.
Recommendations for tarnished cutlery
If the cutlery exhibits tarnishing due to starch or protein, these deposits must be removed by thorough clean-
ing in an immersion bath, for instance. Only then can the cutlery dry without spots after being rinsed in the
machine.
Preparing the immersion bath
Attention! Cleaning agents for commercial dishwashers can cause acid burns. Please take
note of the information on the package.
Wear protective gloves and safety glasses.
Dissolve 200 grams of "Winterhalter Gastronom-Besteckreiniger" in approx. 10 liters of hot water (ap-
prox. 80° C). When the cleaning agent has completely dissolved, put in the cutlery, which must already have
been washed in a dishwasher.
Keep the immersion bath up to heat for approx. 30 minutes if possible and then let it cool to approx. 40° C.
Clean the cutlery with a brush and wash it in the dishwasher. Then it can be rinsed in the GS 310 cutlery
rinsing machine.
Ideal sequence for cleaning cutlery
•Wash the cutlery in the dishwasher as soon as possible after it has been used. If this is impossible, it
should left to soak in a basin (immersion bath with pre-washing agent added) until it can be washed.
Attention! Do not use hand dishwashing agent, since this can cause suds to form in
the machine.
•Wash the cutlery in a dishwasher:
- lying in a rack without divisions, but not piled too high or
- loosely standing and unsorted in cutlery baskets.
•Sort the cutlery in the baskets after it has been washed and then rinse it in the GS 310 cutlery rinsing
machine.
•Thereafter, you can take care of it without having to touch it again.

5.2 Method of functioning
Once the machine has been switched on, the boiler and the tank fill up and are heated to operating tempera-
ture. The program key (6) lights up red during the heating up phase.
As soon as the target temperatures are reached (approx. 60° C for the tank and approx. 85° C for the boiler),
the machine is ready to run. The program key (6) shines green.
The machine can be run with 2 fully automatic programs. The program key (6) shines blue while the program
is running.
An integrated dispensing unit adds the right amount of rinse aid automatically from the reserve container
behind the front paneling.
Cleaning agent is unnecessary because the cutlery has to be washed in a dishwasher beforehand and is
only rinsed in the GS 310.
Do not open the door while the program is running. Hot water could splash out of the ma-
chine.
Do not sit or stand on the open door.
5.3 Rinsing program
The machine has two fully automatic rinsing programs to choose from. Use the operating panel to choose
the program you want.
There is also an additional self-cleaning program for cleaning the interior of the machine at the end of the
working day.
Program Key Explanation
Program 1 Maximum rack capacity: 24 racks/ hr.
Program 2 Maximum rack capacity: 48 racks/ hr.
Empty tank /
self-cleaning program Cleaning the machine:
•rinse water circulates in the rinsing space

8.1 Empty tank; self-cleaning program
Take all cutlery out of the machine.
Close the door.
Press down the function key (2) and hold it down for three seconds to start the self-
cleaning program. The function key will flash.
Now the tank water in the rinsing space will circulate for a while before it is pumped out.
Then the interior of the machine will be rinsed out with fresh, hot water, which will also
be pumped out afterward. When the self-cleaning program is finished, the machine will
switch off automatically. The operating panel will no longer be lit.
Take out the filter cassette and clean it under running water.
Put the filter cassette back in.
Open the door slightly. There is a catch for this purpose in the door latch. This helps the
interior dry out. This is important to prevent rust, even on stainless steel.
8.2 Switching off
When the self-cleaning program is finished, the machine's control will already have switched off automati-
cally. However, the machine is still live.
Close the stop valve on the water supply1.
Switch your own main switch off.
Now the machine is no longer live.
1If a water treatment system is hooked up in front, adhere to the instructions in the documents for this de-
vice.

9 Maintenance and upkeep
To keep the machine functional for a long time, it should be cared for at regular intervals.
In addition, we recommend have Winterhalter customer service overhaul the machine twice each year.
Do not spray the machine with a high-pressure or steam jet cleaning unit.
Take out the filter cassette and clean it under running water.
Put the filter cassette back in.
Open the door slightly. There is a catch for this purpose in the door latch. This helps the
interior dry out. This is important to prevent rust, even on stainless steel.
Clean the outside of the machine with stainless steel polish. We recommend Winterhal-
ter Gastronom stainless steel cleaner and Winterhalter stainless steel polish.
If the flat filter is particularly dirty:
Take out the lower washing fields and rinse them out with water.
Check that the nozzles are clean.
Remove the flat filter and clean it under running water.
Use a brush to clean off any deposits which may have formed in the interior of the machine.
When cleaning, make sure that not foreign bodies which could rust remain in the interior of the machine.
These could cause the interior to rust. These foreign bodies could come from rinsing things not made of
stainless steel, from cleaning aids, damaged wire racks or supply lines which are not rustproof.
