USER MANUAL LXGEPR1 Hobart

SAVE THESE INSTRUCTIONS

GENERAL The LXGe Series glasswashers are fully automatic and front-loading. The LXGe series glasswashers are capable of doing 24 to 38 racks per hour, depending on model. All LXGe Series glasswashers shut down automatically 4 hours after last use to conserve energy. The LXGeR glasswashers include Sense-A-Temp™ to insure proper hot water temperature during rinse. Standard equipment includes one glass/wine rack, electronic controls, drain pump, rinse pump, chemical pumps, ll hose, and drain hose. MODEL DESCRIPTION LXGePR Fresh water rinse; low-temperature, chemical-sanitizing models for use with 6% sodium hypochlorite solution (bleach) as the sanitizing agent*. Note: If 8.40% bleach is to be used, contact Hobart Service or your chemical supplier to change the sanitizer pump settings. (Charges may apply) LXGeR Fresh water rinse with an internal energy recovery unit and a built-in 70°F rise booster heater. Recommended incoming water temperature 55°F to 80°F.

• - Sanitizing agent must be used in accordance with the EPA-registered label use instructions.– 7 – INSTALLATION UNPACKING Immediately after unpacking the glasswasher, check for possible shipping damage. If this machine is found to be damaged, save packaging material and contact the carrier within 15 days of delivery. LOCATION Prior to installation, verify that the electrical supply agrees with the specications on the machine data plate, which is located on the top of the door. Steam generated from normal operation may escape from the door. Wood, laminates, veneers, etc. are unsuitable materials for use in areas exposed to glasswasher steam and detergents. Stainless steel or other moisture-resistant shields are recommended for surfaces adjacent to LXGe sides and top. LEVELING The machine must be level to operate properly. Place the glasswasher in its operating location. Level the machine before any connections are made. Using a carpenter's level placed diagonally on the rack tracks, level the machine front to back and side to side by threading the adjustable feet in or out. WATER REQUIREMENTS Proper water quality can improve glass 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 efcient 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 glasswasher, and reduce detergent usage in the glasswasher. High iron levels in the water supply can cause staining and may require an iron lter. 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 lter. 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 glasswasher 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 sufcient level of salt. Contact your local Hobart Service ofce for specic recommendations.– 8 – A water hammer arrestor (meeting ASSE-1010 Standard or equivalent) should be installed (supplied by others) in the common water supply line at the service connection. The plumber connecting this machine is responsible for making certain that water lines are THOROUGHLY FLUSHED OUT BEFORE connecting to the glasswasher. This "ush-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 ttings are used, bits of solder or cuttings from the tubing. Debris, if not removed, may lodge in the glasswasher'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: MODEL TEMPERATURE LXGePR 120°F Minimum LXGeR 55°F Minimum, 85°F Maximum NOTE: On LXGeR installations, if cold water supply temperature is consistently above 80°F 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 owing water pressure to the glasswasher 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 glasswasher (by others). If owing pressure is less than 15 psi, improper machine operation may result. All LXGe glasswashers are equipped with a pumped rinse system; therefore, a water pressure gauge is not required and is not supplied with the machine. 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 ll 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

⁄2" minimum copper piping OD (

⁄4" recommended), with a

⁄4" male garden hose tting (not supplied). See installation diagrams, pages 14-17. PLUMBING CONNECTIONS Plumbing connections must comply with applicable sanitary, safety, and plumbing codes. Drain A drain hose,

⁄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 14-17. Drain must have a minimum ow capacity of 5 gallons per minute.

This machine must be cleaned after installation and before being put into operation. (See Cleaning)– 9 – ELECTRICAL CONNECTION Electrical and grounding connections must comply with the applicable portions of the National Electrical Code and/or other local electrical codes. Disconnect the electrical power to the machine and follow lockout/tagout procedures. ELECTRICAL DATA Complied in accordance with the National Electrical Code NFPA-70, latest addition. For supply connections, use copper wire only rated at 90°C minimum. *The (3W) systems require three power wires that include a current carrying neutral. An additional fourth wire must be provided for machine ground. Refer to the top of the door of the machine and the electrical label on the back side of the lower front panel for proper selection. ledoM esahP/ztreH/stloV tiucriCylppuSmuminiM yticapmArotcudnoC evitcetorPmumixaM yticapmAeciveD LXGePR 1/06/021 LXGeR

DETERGENT AND RINSE AID

Use only commercial-grade detergents recommended by your chemical professional. Do not use detergents formulated for residential glasswashers. The detergent and rinse aid pump "ON" times are factory-set. If adjustments are required, contact your local Hobart Service Ofce or your chemical supplier. Place the detergent and rinse aid containers (which are obtained from an independent supplier) under the glasswasher. Remove the detergent bottle cap and put the red delivery tube in the detergent container by snapping the bottle connector onto the container. Remove the rinse aid bottle cap and place the blue delivery tube in the rinse aid container by snapping the bottle connector onto the container. Be sure to push the delivery tubes completely to the bottom of each container. Check to make sure there are no obstructions or kinks in the delivery tubes. KNOCKOUT– 12 – CHEMICAL SANITIZER (LXGePR) Items such as pewter, aluminum and silver will be attacked by sodium hypochlorite (bleach). Therefore, chemical-sanitizing glasswashers should not be used to wash such items. The LXGePR chemical sanitizer pump is factory-set for use with 6% sodium hypochlorite solution. If 8.40% sodium hypochlorite solution is to be used, contact your local Hobart Service Ofce. On LXGePR models, place a sanitizer approved for potable water rinse machines under the glasswasher no higher than 10 inches off the oor. Do not pre-mix sanitizing solution with water or any other liquid. Never premix a wetting agent with the sanitizing solution. Mixing may cause hazardous gas to form. Remove the sanitizer bottle cap and place the white delivery tube in the sanitizer container by snapping the bottle connector onto the container. Be sure to push the delivery tube completely to the bottom of the container. Check to make sure there are no obstructions or kinks in the delivery tube. Frequently check your sanitizer bottle to make sure there is a sufcient chemical supply.

CHECKING SANITIZER CONCENTRATION

Verify there is sufcient chemical supply in the sanitizer bottle and that the delivery tube standpipe is inserted completely to the bottom of the chemical container. Place a glass rack, with glasses, in the machine. On LXGePR models, the PuriRinse feature must be deactivated to properly check the sanitizer concentration. To deactivate PuriRinse, press and hold the WASH key for ve seconds until wash cycle starts. Follow the directions precisely that are on the litmus paper vial and test the water on the surface of the bottom of the glasses. Concentration should be 50 p.p.m. minimum to 100 p.p.m. maximum. If reading is incorrect, contact your local Hobart Service Ofce or chemical provider for adjustments. DELIMING SOLUTION All LXGePR and LXGeR models are equipped with an automatic deliming system. At installation, a qualied 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 by snapping the bottle connector onto the container. Be sure to push the delivery tube completely to the bottom of the container. Check to make sure there are no obstructions or kinks in the delivery tube.– 13 –

PRIMING CHEMICAL PUMPS

When a chemical becomes empty, the priming operation starts automatically the next time the machine is turned on or a wash cycle is started. Note that the initial prime time for all pumps (Detergent, Rinse Agent, and Sanitizer) is 60 seconds. If the chemical is not sensed within 60 seconds, the add chemical indicator will ash. After the chemical is sensed, the indicator in the display turns off; and the pump continues to prime for 10 seconds to allow the chemicals to reach the machine. If all chemicals are empty, the sanitizer will prime rst followed by detergent. Only one chemical pump will run at a time. If chemicals are not sensed after three consecutive priming operations, the add chemical indicator will ash and priming is cancelled. The next time a wash cycle is started, the add chemical indicator will continue to ash. Verify that the chemical bottles are not empty and that the delivery tubes are inserted completely to the bottom of the containers. The priming operation can be reset by turning the glasswasher off, then back on. If the chemical bottles are not empty and the delivery tubes are inserted correctly, then the chemical sensor or pumps may have malfunctioned; contact your local Hobart Service Ofce.– 14 – Do not pre-mix other chemicals and sodium hypochlorite (liquid bleach). Mixing may cause hazardous gas to form. Required owing 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). Pressure guage not provided on pumped rinse machines. Important: The chemical containers should be placed no higher than 16" above oor. If chemical containers are to be placed in cabinet adjacent to machine, a 1/2" dia. hole is required in the cabinet to run chemical supply line. Use only 6% or 8.4% sodium hypochlorite (liquid bleach) as sanitizing chemical to insure proper operation of dishmachine. Certain materials including silver plate, aluminum and pewter are attacked by sodium hypochlorite (liquid bleach). NOTES:

1. All vertical machine dimensions taken from oor may be increased by .875" or decreased by .375".

2. Moist air escapes from the door.

Use only moisture resistant materials adjacent to dishmachine sides and top.

3. A vent hood is not recommended above the undercounter dishmachine since it does not produce

excessive vapors. PLUMBING NOTES:

1. Water hammer arrestor (meeting ASSE-1010 standard or equivalent) to be supplied (by others) in

common water supply line at service connection.

2. Recommended water hardness to be 3 grains or less for best results.

Fig. 8 RINSE ARM CENTER HUB BUTTONS LXGePR & LXGeR– 28 – MAINTENANCE Maintenance and regular care is important to maintain optimal results with your Hobart glasswasher. DELIMING Deliming solution, rinse agents or any other kind of acid must not come in contact with bleach or rinse solution containing bleach used in chemical-sanitizing machines. Mixing may cause hazardous gas to form. This entire procedure must be followed step by step for safe and satisfactory results. Do not allow the deliming agent to remain in the machine longer than recommended by the deliming agent manufacturer. DELIME THE GLASSWASHER ON A REGULAR BASIS AS REQUIRED. The regularity will depend on mineral content of the supply water. Deliming should be done when you can see clear signs of lime deposits (a white, chalky substance) on the inside walls and on the wash arms. All LXGe glasswashers are equipped with an automatic delime cycle reminder and are equipped with an internal delime pump which will automatically pump the required amount of deliming agent into the unit. If deliming is necessary, a deliming agent (such as Lime-A-Way

) should be used for best results. 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

2. Remove dish rack from machine.

3. Remove strainers from machine and clean. Replace strainer, empty rack and close door.

4. 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 rell with fresh water.

6. The unit will automatically enter the wash mode for 10 minutes, then will begin two rinse and drain

operations after the ll cycle is complete.

7. After the deliming operation is completed, power to the control will be turned off.

8. Inspect the interior of the machine for lime deposits. If necessary, another delime cycle can be

initiated by entering the Manager Programming Mode. LUBRICATION The pump motor has permanently sealed bearings and requires no lubrication.– 29 – TROUBLESHOOTING This section outlines various symptoms and possible causes that may be encountered in the event of abnormal machine operation.
