INSTALLATION, OPERATION AND CARE OF

MODEL UW50 UTENSIL WASHER

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.

INSTALLATION

UNPACKING

Immediately after unpacking the UW50, check for possible shipping damage. If the UW50 is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery.

If the Utensil Washer is lifted with a lift truck, place the forks so the drain assembly under the tank is not damaged.

Prior to installation, test the electrical service to ensure that it agrees with the speciﬁ cations on the data plate located below the controls (lower right front).

INSTALLATION CODES

Installation must be in accordance with state and local codes, with the national Fuel Code, ANSIZ223.1 (latest edition), if applicable, and the National Electrical Code ANSI/NFPA70 (latest edition). In Canada, the installation codes are: CAN/CGA B149.1, CAN/CGA B149.2 and CSA 22.1 (latest edition).

LOCATION

Set the machine in place after the ﬁ nal ﬂ oor covering is installed. Make sure the machine is level before making any plumbing connections. Machines equipped with gas heat require a minimum 3" clearance from the rear of the ﬂ ue to any combustible construction. Allow at least 3" at the rear and 18" at the sides of the machine as a suggested minimum for service access. Allow 13" in front of the machine for the door to lower and sufﬁ cient additional space for the operator to work.
