Installation, Operation and Care Of Model PW10/PW20 Prep Washer SAVE THESE INSTRUCTIONS

GENERAL

The PW10 and PW20 Prep Washer is the answer to volume utensil washing problems in your kitchen, bakery or supermarket operation. The PW10/20 occupies a minimum amount of floor space (under 48'' × 43'' with door open) and does not require separate dish tables. 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 key pad lets you select a 2-, 4- or 6-minute cycle; each wash cycle is followed by a dwell. After the dwell is a 10 (PW10, PW10eR, PW20) or 12 (PW20eR) second rinse. Advansys models include a 112 to 212 minute condensing time following the rinse cycle. The upper and lower wash arms provide thorough cleaning. Upper and lower rinse arms provide a sanitizing rinse at the end of each cycle.

The PW10/20 is only available with electric tank heat and electric booster is standard. A spray hose and nozzle is provided on the side of the machine.

Features include: sloping strainer system, pumped drain, automatic fill, and rack with inserts for trays. The flat rack can accommodate a 140-quart Hobart mixer bowl.

Water Requirements

Proper water quality can improve ware washing performance by reducing spotting, enhancing effectiveness of labor and extending equipment life. Water conditions vary from one location to another. The recommended proper water treatment for effective and efficient use of this equipment will also vary depending on the local water conditions. Ask your municipal water supplier for details about your local water conditions prior to installation.

Recommended water hardness is 3 grains of hardness per gallon or less. Higher hardness may cause excessive formation of lime scale. Water hardness above 3 grains per gallon requires water treatment. Water treatment has been shown to reduce costs associated with machine cleaning, reduce deliming of the dishwasher, and reduce detergent usage in the dishwasher. Chlorides must not exceed 50~ppm .

NOTICE High iron levels in the water supply can cause staining and may require an iron filter. High chloride levels in the water supply can cause pitting and may require a chloride removal system. Contact your local water treatment professional for proper water treatment.

Sediment may require a particulate filter. Dissolved solids may require water treatment such as a water softener, reverse osmosis system, etc. Contact your local water treatment professional for proper water treatment.

If an inspection of the dishwasher or booster heater reveals lime buildup after the equipment has been in service, water treatment is recommended. If a water softener is already in place, ensure there is a sufficient level of salt. Contact your local Hobart Service office for specific recommendations.

Water Supply Connection

The water supply line should be a 34 male garden hose (supplied by others).

The plumber connecting this machine is responsible for making certain that water lines are THOROUGHLY FLUSHED OUT BEFORE connecting to the dishwasher. This "flush-out" is necessary to remove all foreign matter, such as chips (resulting from cutting or threading of pipes) pipe joint compound from the lines; or, if soldered fittings are used, bits of solder or cuttings from the tubing. Debris, if not removed, may lodge in the dishwasher's plumbing components and render them inoperative. Manual valves or solenoid valves fouled by foreign matter and any expenses resulting from this fouling are NOT the responsibility of the manufacturer and associated repair costs are not covered under warranty.

Water supply requirements are as follows:

WATER SUPPLY REQUIREMENTS

Model Supply	ly Temperature
PW10 Hot Water	110°F Minimum
PW10eR Cold W	ater 55°F Minimum, 80°F Maximum
	Hot Water 110°F Minimum
PW20 Hot Water	110°F Minimum
PW20eR Cold W	ater 55°F Minimum, 80°F Maximum
	Hot Water 110°F Minimum

PW10eR and PW20eR models require both a cold water supply connection and a hot water supply connection.

NOTICE On PW10eR and PW20eR installations, the cold water supply must not exceed 80^ (27^) for proper operation. Optimal results are obtained when cold water supply temperature is below 65^ (18^) . For best results, it may be necessary to use 12 pipe for cold water pipe size and minimize the distance between the dishwasher and the entrance into the building. Pipe insulation will also improve results.

If cold water supply temperature is consistently above 80^ (27^) or if excessive water vapor or steam is entering the room after the condensing cycle is complete, contact Hobart Service to increase condensing time.

Required flowing water pressure to the dishmachine is 15-65 PSIG. If pressures higher than 65 PSIG are present, a pressure regulating valve must be installed in the water line to the dishmachine (by others). If flowing pressure is less than 15 psi, improper machine operation may result. All PW models are equipped with a pumped rinse system; therefore, a water pressure gauge is not required and is not supplied with the machine.

NOTICE The water pressure regulator must have a relief bypass. Failure to use the proper type of pressure regulator may result in damage to the unit.

A manual shutoff valve (not supplied) should be installed upstream of the fill hose to accommodate servicing the machine.

It is recommended that a line strainer (not supplied) be installed in the supply line between the manual shutoff valve (not supplied) and the connection point on the machine. Make plumbing connections with 12 minimum copper piping OD (34) recommended), with a 34 male garden hose fitting (not supplied). See installation diagrams, pages 11-14.

Plumbing Connections

WARNING Plumbing connections must comply with applicable sanitary, safety, and plumbing codes.

Drain

A drain hose, 7/8" inside diameter and 6' long, is provided. This should be securely plumbed into a drain. Use care not to kink hose. See installation diagrams, pages 11-14. Drain must have a minimum flow capacity of 18 gallons per minute for PW10/ PW10eR and 26 gallons per minute for PW20/PW20eR.

Venting Requirements (PW10 / PW20)

Type I or type II canopy hoods are recommended. Hoods must be installed according to the manufacturer's instructions. Make-up air must be provided so that the exhaust flow rate results in a negative building pressure in the room where the unit is located (more exhaust air than outside air). Factory-built hoods not tested to UL standard 710 and custom-built hoods must comply with the following specifications: Stainless steel should have a minimum thickness of 0.037 in. (0.94mm) [No. 20 Gauge] or copper sheet weighing at least 24 ounces per square foot (7Kg / m2) ; the hood must be secured in place by noncombustible supports and must meet the RATE of EXHAUST FLOW CALCULATIONS.

NOTICE Make sure the installation meets the local code for your area.

Rate of Exhaust Flow Calculations (FIG. 14)

Based on the 2015 International Mechanical Code.

Fig. 15

Canopy Size and Location

The inside lower edge of canopy-type type I and II commercial hoods shall overhang or extend a horizontal distance of not less than 6 inches (152 mm) beyond the edge of the top horizontal surface of the appliance on all open sides. The vertical distance between the front lower lip of the hood and such surface shall not exceed 4 feet (1219 mm) with a minimum of 1 foot (305 mm).

18" min overhang of the front opening.

The RATE of air flow required for a vent hood is a minimum of 100 CFM per linear foot of hood length.

Rate of Exhaust Flow Calculations

Based on the 2015 International Mechanical Code.

The minimum net airflow for Type II hoods used for dishwashing appliances shall be 100 cfm per linear foot of hood length. The net quantity of exhaust air shall be calculated by subtracting any airflow supplied directly to a hood cavity form the total exhaust flow rate of a hood.

Models PW10eR and PW20eR do not require a Type II vent hood. According to 507.3 of the 2015 IMC, Type II hoods are not required where the heat and moisture loads is incorporated in the HVAC system design. See Table A for heat dissipation or heat gain to space.

For Advansys models only - If excessive amounts of steam or water vapor exit the machine after condensing cycle light goes out and door is opened, incoming cold water temperature may be too high.

Contact Hobart Service to adjust the rinse and condense times according to the adjustment table. Increasing cycle time will increase water consumption and decrease the racks per hour, but should reduce the water vapor entering the room.

General Operating Instructions

Keep the prep washer clean to provide best results. Do not allow foreign objects to enter the unit, especially metallic contaminants.

Do not wash aluminum utensils in the prep washer. The caustic detergent and high water temperature will cause aluminum oxide formation (black). Copper utensils may require polishing to remove oxide formation after exposure to utensil washer cleaning for a period of time. Stainless steel utensils should clean quickly and easily if the food soil is not baked on.

It may be necessary to scrub or prewash some hard-to-remove substances which may not come clean in the prep washer with even a 6-minute washing. For stubborn food soil, a plastic scraper, plastic abrasive pad, nylon bristle brush or sponge with abrasive surface (Scotch Brite) may be used before washing in the prep washer. Never use steel wool on ware to be loaded into the prep washer. Use only products formulated to be safe on stainless steel. Do not use deliming agent on outside of machine. Rinse items thoroughly after scrubbing to remove metallic debris.

MAINTENANCE

MOTOR

The motor has permanently sealed bearings and requires no lubrication.

WASH AND RINSE ARMS

All wash arms and rinse arms should turn freely and continue turning for a few seconds after being whirled by hand. To check, DISCONNECTELECTRIC POWER SUPPLY, rotate arms and remove any obstructions causing improper operation. Refer to CLEANING THE PREP WASHER on pages 27-31.

If the strainer pans and strainer basket are not properly in place, obstructions (such as food particles or toothpicks) may clog the wash arm nozzles.

DELIMING

WARNING Deliming solution must not come in contact with bleach or rinse solution containing bleach. Mixing may cause hazardous gas to form. This entire procedure must be followed step-by-step for safe and satisfactory results.

The dishwasher should be delimed on a regular basis as required. How often depends on the mineral content of the water. Deliming should be done when you can see clear signs of lime deposits (a white chalky substance) on the inside walls, on the wash and rinse arms and tank heater. Inspect the machine interior for lime deposits. If deliming is necessary, a deliming agent (such as Lime-A-Way® or LSR®) should be used for best results.

All Prep washers are equipped with an automatic delime cycle reminder. It is recommended that deliming be done when DELIME RECOMMENDED is lit. PW10eR and PW20eR models are equipped with an internal delime pump which will automatically pump the required amount of deliming agent into the unit. All PW10eR/PR20eR models are equipped with an automatic deliming system. At installation, a qualified Hobart Service technician or your chemical supplier must adjust the total water hardness setting to properly set the delime intervals.

Remove the deliming agent bottle cap and put the black delivery tube in the container. Be sure to push the delivery tub standpipe completely to the bottom of the container. Check to make sure there are no obstructions or kinks in the delivery tube.

After the preprogrammed number of cycles has expired, the control will indicate the delime request by displaying DELIME RECOMMENDED and will prompt 'would you like to delime now?' . You must enter Yes' or No' to proceed with a delime cycle or to continue with normal machine operation. If No' is selected, the machine will continue to notify the operator at each start-up and power down until the delime cycle is completed. To delime the unit.

1. Press the MENU/DOWN Arrow key until the > symbol is shown to the left of 'YES' and press the ENT key.
2. Remove rack from the machine.
3. Remove strainers from the machine and clean. Replace strainers and rack and close door.
4. On PW10er/PW20eR machines, ensure delimer chemical container is not empty. Be sure to push the delivery tube standpipe completely to the bottom of the container. Check to make sure there are no obstructions or kinks in the delivery tube.
5. Press ENT key to enter the delime mode. The machine will drain and refill with fresh water.
6. On PW10/PW20 machines, after the deliming agent has been added, close the door. Press the ENT key to continue the cycle. The machine will enter the wash mode for about 25 minutes, then will begin two rinse and drain operations. Total time to complete the delime operation will be about 45 minutes. ON PW10eR/ PW20eR machines, the unit will automatically enter the wash mode for about 40 minutes, then will begin several rinse and drain operations after the fill cycle is complete. Total time to complete the delime operation will be about 1 hour 40 minutes.
7. After deliming operation is completed, the machine will shut down.
8. Inspect the interior of the machine for lime deposits. If necessary, another delime cycle can be initiated by entering Manager Programming Mode.

NOTICE Do not allow deliming agent to remain in the machine longer than recommended by the deliming agent manufacturer. After deliming, run the machine through two 6-minute cycles with no utensils in order to rinse and flush machine interior.
