English | 3 | Machine description
Automatic hood start
Closing the hood automatically starts a washing programme. The automatic hood start can be deactivated by an author­ised service technician (P572). Every washing programme will then need to be started by pressing the start button.
Automatic hood mechanism (optional for PT-M and PT-L)
The hood opens automatically after every washing programme and can be closed again using the start button on the front cover.
EnergyPlus (optional)
Note:Cold water connection required.
The Energy module above the warewasher includes a fan motor and a heat exchanger. The fan motor extracts the moist, warm air (=vapours) out of the washing compartment and transfers the generated energy to the cold inlet water via a heat exchanger. A waste water heat exchanger provides an additional energy gain.
ClimatePlus (optional for PT-M and PT-L)
Note:Cold water connection required.
The heat pump module above the warewasher includes a fan motor and a heat pump. The fan motor extracts the moist, warm air (=vapours) out of the washing compartment and the area around the warewasher and transfers the generated energy to the cold inlet water via a heat exchanger.
Cool (optional)
Note:Cold water connection required.
The rinse temperature can be changed for warewashers with this option. Glasses are ready to be used again faster with cold rinsing.
Utensil (optional for the PT-L and PT-XL)
Warewashers with this option combine two applications and can wash both utensils (e.g. pots, trays) and dishes. Two tank heaters are installed to maintain the tank water temperature.
Integral water softener (optional)
Warewasher with built-in salt container for regeneration salt. The regeneration salt softens the inlet water and thus pre­vents a build-up of limescale inside the warewasher and on the items being washed.
PAY PER WASH (optional)

3.6 Chemicals

Operate the warewasher with chemicals from Winterhalter. Contact Winterhalter or an authorised customer service team before using other chemicals.
Rinse aid
Rinse aid is required to ensure that water on the wash items runs off as a thin film after washing. This helps the wash items to dry quickly.
Rinse aid is automatically dispensed using an integrated or external dosing device.
Detergent
A detergent is required to dissolve food residues and dirt on the wash items. Detergent is automatically dispensed using an (optional) integrated or external dosing device.
To avoid damaging the warewasher and to achieve a good wash result:
– Do not use acidic detergents.
– Do not use foaming products (e.g. manual washing-up liquid) for pre-treating the wash items.
Defoamer
Defoamer is necessary if heavy foam formation prevents a good wash result. Defoamer is automatically dispensed using an (optional) integrated dosing device.

4.2.7 Basic cleaning

The menu-guided basic cleaning programme is used for the thorough cleaning of wash items:
– Removal of starch residues from dishes
– Basic cleaning of new glasses
– Removal of residues on glasses
We recommend running the basic cleaning programme at the end of the working day, as the machine’s tank is emptied when the programme ends. This programme requires a basic cleaner that is suitable for commercial warewashers. For dishes, Winterhalter recommends the A 20 ST basic detergent, and for glasses the A 25 GL basic cleaner.
WARNING
Risk of chemical burns due to chemicals
Chemicals can cause severe burns or serious eye damage if they come into contact with the skin or eyes.
Ø In the event of contact with the eyes or skin, wash thoroughly with tap water. If necessary, seek medical
attention.
Ø Wear protective clothing, protective gloves and protective goggles. Ø Read and observe the danger and safety notes on the container and safety data sheet.
Starting the basic cleaning programme
Follow dosing recommendations when adding the basic cleaner. The initial dose for the first use of the programme de­pends on the machine’s tank volume.
The post-dosing for each additional programme depends on the rinse water volume.

4.2.8 Descale

If the warewasher is operated in a hard water area without a water treatment system, then the boiler, the machine interior and all water-bearing lines and components may develop scale. Limescale deposits and the dirt and residual grease they contain present a hygiene risk, while scaling can cause heating elements to fail. If limescale deposits form, the ware­washer must be descaled.
The interior of the warewasher can be descaled using the descaling programme (} page 23). We recommend running the descaling programme at the end of the working day only because the machine’s tank is emptied when the programme starts and ends.
The descaling programme is used to descale the interior of the warewasher. We recommend running the descaling pro­gramme at the end of the working day only because the machine’s tank is emptied when the programme starts and ends.
Water-bearing lines and the boiler can only be descaled by an authorised service technician. For descaling, you require an acid-based descaler suitable for commercial warewashers. Winterhalter recommends A 70
LS descaler.
WARNING
Risk of chemical burn due to contact with descaler
Contact between descaler and the skin or eyes can lead to severe burns or serious eye damage.
Ø Wear protective clothing, protective gloves, protective goggles and protective mask. Ø Observe the hazard and safety notes on the canister and the safety data sheet.
WARNING
Danger of chlorine gas developing
Mixing active chlorine cleaner and acid-based descaler produces chlorine gas. Contact with chlorine gas leads to eye, nose and throat irritations.
Ø Do not mix active chlorine cleaner and acid-based descaler. Ø Ensure good ventilation when you descale the warewasher.
NOTE
Danger of corrosion due to descaler solution
Descaler solution has a corrosive effect when in contact with metals and plastics for a long time and there­fore must not remain in the interior of the machine (e.g. overnight).
Ø Do not cancel the descaling programme and follow the instructions on the display.
Starting the descaling programme
When adding the descaler, observe the tank volume and dosing recommendation.

Risk of chemical burns due to chemicals
Chemicals can cause severe burns or serious eye damage if they come into contact with the skin or eyes.
Ø In the event of contact with the eyes or skin, wash thoroughly with tap water. If necessary, seek medical
attention.
Ø Wear protective clothing, protective gloves and protective goggles. Ø Read and observe the danger and safety notes on the container and safety data sheet.
Five seconds after the soaking programme has started, the wash pump circulates the tank water for seven seconds. The soaking time of five minutes begins after this circulation. The tank water moistens the wash items and soaks the contam­inants.
– If you open the hood during this time and close it again within 10 seconds, the wash pump circulates the tank water
again for five seconds. The soaking time is not extended.
– If you open the hood for longer than 10 seconds to put more wash items into the wash rack, the soaking programme
will start once the hood has been closed. A washing programme starts automatically after the end of the soaking period. The soaking period can also be shortened by pressing the start button.
A service technician can adjust the times mentioned above.

Self-cleaning programme
The self-cleaning programme is helpful for cleaning the inside of the warewasher at the end of the work day. We recom­mend that you also use A 15 MC cleaning tablets. The A 15 MC cleaning tablets help to remove unpleasant odours and light limescale deposits.
After the first programme step, the self-cleaning programme is interrupted and a video with further steps is shown on the display. If no notice is taken of the video, the self-cleaning programme will start automatically.
Cancelling the self-cleaning programme
Cleaning the warewasher interior
Make sure that there are no rusting foreign bodies inside the warewasher that could also cause stainless steel to rust. Rust particles can come from non-rust wash items, from cleaning aids, damaged wire grate racks or from water pipes that are not protected against rust.
To achieve an optimal wash result and to increase the service life of the warewasher, we recommend cleaning the interior daily.
Ø Hose down the interior with a water hose.
Ø Remove dirt with a brush or cloth.

8.3 Topping up the regeneration salt

NOTE
Risk of damaging the water softener
Chemicals, e.g. detergent, rinse aid or other salts, such as table salt or thawing salt, will inevitably damage the water softener.
Ø Only fill with regeneration salt with a maximum grain size of 0.4–7mm.
Ø Only fill with water when commissioning the water softener for the first time.
Ø Top up the regeneration salt.
Cleaning and maintenance | 8 | English
Ø Note:Danger of rust formation in the filling area as a result of salt residues! After filling the regeneration salt,
start a washing programme or the self-cleaning programme in order to wash away any salt residues that may be present. We recommend starting the self-cleaning programme, as salt residues can have a negative impact on the wash result.

8.4 Replacing the canister

WARNING
Risk of chemical burns due to chemicals
Ø Read and observe the danger and safety notes on the container and safety data sheet. Ø Wear protective clothing, protective gloves and protective goggles.
A suction tube is needed to suck out the chemicals from the containers.
– Do not place the suction tube for the rinse aid in the container holding detergent defoamer, or vice versa.
– Use the suction tube only with sufficiently stable containers. Narrow and tall containers can tip as soon as the suction
tube is pulled.
– Do not pull on the dosing hose or main power cable, as this may lead to a defect.
Ø Wear protective clothing, protective gloves and protective goggles.
Ø Pull the suction tube carefully out of the empty canister.
Ø Check whether both vent holes (1) in the cover cap are open. Clean if required.
Ø Place suction tube in the new canister.
Ø Slide the cover cap slowly downwards until the canister opening is closed.
Ø Prime the dosing device.
Priming the dosing devices
The dosing device must be primed if air has entered the dosing hose. This occurs if the canister is not replaced in time.
Item Description
1 Rinse aid dosing device 2 Detergent dosing device 3 Defoamer dosing device
Ø Press button 1, 2 or 3.
ð The button turns white.
ð The dosing device is primed.
Ø As soon as the button light goes out, exit the menu.

8.5 Changing the chemicals

Crystallisation can occur as a result of mixing different chemical products, which can damage the dosing device. The dosing device and the dosing hoses must therefore be flushed with water before a new chemical product is used. If this is not done, the Winterhalter Gastronom GmbH warranty and product liability will be void.
Ø Remove the suction tube from the canister and place it in a water-filled container.
Ø Rinse the dosing device with water via the “Priming” menu.

ð The water in the dosing hoses and dosing device is replaced by the new chemical product.
The dosing must also be reset.
Ø Use an authorised service technician to continue to attain good wash results.

8.6 Descaling the warewasher

If the warewasher is operated in a hard water area without a water treatment system, then the boiler, the machine interior and all water-bearing lines and components may develop scale. Limescale deposits and the dirt and residual grease they contain present a hygiene risk, while scaling can cause heating elements to fail. If limescale deposits form, the ware­washer must be descaled.
The interior of the warewasher can be descaled using the descaling programme (} page 23). We recommend running the descaling programme at the end of the working day only because the machine’s tank is emptied when the programme starts and ends.
The descaling programme is used to descale the interior of the warewasher. We recommend running the descaling pro­gramme at the end of the working day only because the machine’s tank is emptied when the programme starts and ends.
Water-bearing lines and the boiler can only be descaled by an authorised service technician.

8.7 Maintenance by the customer service department

We recommend that you have the warewasher serviced by an authorised service technician at least once a year so that vulnerable components subject to ageing and wear can be checked and replaced as required. Original spare parts must be used for repairs or to replace consumable parts.
Consumable parts include:
– Dosing tubes
– Supply hose
Service interval
The warewasher control unit specifies the number of operating hours or wash cycles at which the pic­togram for service is shown.
Note:This function is deactivated ex-works. On request, the service technician can activate this function.
