SAVE THESE INSTRUCTIONS
GENERAL
The UW50 Utensil Washer is the answer to volume utensil washing problems in your kitchen, bakery or
supermarket operation. The UW50 occupies a minimum amount of fl oor space (under 48" x 43" with door
open) and does not require separate dishtables. The upper portion of the door raises, while the lower portion
swings out to provide a drain platform. The rack can then be pulled out for easy loading and unloading.
The program selector lets you select a 2-, 4- or 6-minute cycle; each wash cycle is followed by a dwell
and a 24-second rinse. The two upper and two lower wash arms provide thorough cleaning. Four rinse
arms provide a sanitizing rinse at the end of each cycle. The 5-horsepower pump produces 343 gallons
per minute.
The UW50 may be ordered with steam injector, steam coil, electric or gas tank heat. A top-mounted electric
booster is also available. When equipped with a top-mounted electric booster, a spray hose and nozzle
is provided on the left side of the machine. On models without top-mounted electric boosters, the spray
hose and nozzle can be installed in the fi eld as an accessory. Machines equipped with booster heaters
are provided with a pressure-regulating valve and a relief bypass which must be installed in the water
supply line. Machines without booster heaters must have a pressure-regulating valve with relief bypass
(by others) if the incoming line pressure exceeds 25 psig.
Features include: sloping strainer system, self-closing drain with overfl ow, timed fi ll, wash and rinse
thermometers and rack with inserts for trays. The fl at rack can accommodate a 140-quart Hobart mixer
bowl.
