The Winterhalter Gastronom utensil washers GS 640, GS 650, and GS 660 are industrial machines designed for washing items and utensils in catering, butcher shops, and bakeries. These operating instructions must always be kept within easy reach of the utensil washer.

Function Description:

The utensil washer operates with fully automatic programs consisting of washing, dripping off, and rinsing. After being switched on, the machine fills and heats its boiler and tank to operating temperatures (tank: approx. 60°C, boiler: approx. 85°C). Once these temperatures are reached, the program button (6) lights green, indicating readiness for operation.

During the washing phase, a circulating pump conveys wash water from the tank through wash arms and nozzles onto the items. The wash arms move side to side to ensure powerful and efficient cleaning. The wash water is continuously circulated through a filtering system and a patented Mediamat Cyclo (floating particle separator). A short pause follows washing, allowing wash water to drip off the items. The final step is rinsing with fresh, hot water to remove residual water and warm the items for optimal drying. This rinse water also refreshes the wash water in the tank.

The machine supports various wash programs:

Normal programme (6): For normally soiled items, offering a medium drying time.
Short programme (10): For lightly soiled items, providing short or no drying time.
Intensive programme (13): For heavily soiled items, with a long drying time.
Normal programme with cold water pre-rinse (optional) (12): Designed for items with protein-containing soiling, where cold water rinsing prevents coagulation.
Tank drainage / self-cleaning (2): An automatic cleaning program where the wash pump activates for 30 seconds to clean the wash tank. Soiled wash water is pumped off, and the interior is rinsed with fresh water. The machine switches off automatically after this program.

Important Technical Specifications:

Water Temperatures: Tank approx. 60°C, Boiler approx. 85°C.
Detergent Dosing: Can be manual (powder) or automatic (liquid) via a built-in or external dosing pump. For GS 660, detergent and rinse additive containers can be stored inside the machine; for other models, they are stored separately.
Water Hardness: Greater quantities of detergent may be needed for heavily soiled items or extreme water hardness.
Hoseproof Rating: IP X5 (hoseproof), but high-pressure or steam jet cleaners are prohibited for external cleaning.
Noise Emission: Workplace related emission value measured according to DIN EN ISO 11202: LpAeq < 70dB.
Tank Volume: GS 640, GS 650: 85 liters; GS 660: 125 liters.
Detergent Dosage (Winterhalter Gastronom Detergent P 65):
- GS 640, GS 650: 255g (1 measuring cup) for initial dosage; 75g (1/2 measuring cup) for manual addition after approx. 5 wash cycles.
