SPECIFICATIONS ELECTRICAL REQUIREMENTS PERFORMANCE/CAPABILITIES WASH PUMP MOTOR HORSEPOWER OPERATING CAPACITY (RACKS/HOUR) RACKS PER HOUR 24 DISHES PER HOUR 600 GLASSES PER HOUR 600 NOTE: Typical Electrical Circuit is based upon (1) 125% of the full amperage load of the machine and (2) typical fixed-trip circuit breaker sizes as listed in the NEC 2002 Edition. Local codes may require more stringent protection than what is displayed here.
INSTALLATION INSTRUCTIONS Jackson MSC Inc. provides technical support for all of the dishmachines detailed in this manual. We strongly recommend that you refer to this manual before making a call to our technical support staff. Please have this manual with you when you call so that our staff can refer you, if necessary, to the proper page. Technical support is available from 8:00 a.m. to 5:00 p.m. (EST), Monday through Friday. Technical support is not available on holidays.
INSTALLATION INSTRUCTIONS (CONTINUED) ELECTRICAL POWER CONNECTION: Electrical and grounding connections must comply with the applicable portions of the National Electrical Code ANSI/NFPA 70 (latest edition) and/or other electrical codes. Disconnect electrical power supply and place a tag at the disconnect switch to indicate that you are working on the circuit. The dishmachine data plate is located on the front of the machine.
CHEMICAL DISPENSING EQUIPMENT The Conserver 24LT dishmachine is not supplied with integral chemical dispensing feeder pumps. Instead, an independent chemical dispensing system must be connected to the unit prior to use in order to achieve required cleanliness and sanitation. Please consult the literature that accompanied your independent chemical dispensing system for information concerning installation and operation of the dispenser.
DETERGENT CONTROL Detergent usage and water hardness are two factors that contribute greatly to how efficiently your dishmachine will operate. Using detergent in the proper amount can become, in time, a source of substantial savings. A qualified water treatment specialist can tell you what is needed for maximum efficiency from your detergent, but you should still know some basics so you’ll understand what they are talking about.
OPERATION INSTRUCTIONS PREPARATION: Before proceeding with the start-up of the unit, verify the following: 1. The strainer is in place and is clean. 2. That the wash arms are screwed securely into place and that their endcaps are tight. The wash arms should rotate freely. 3. Verify all chemical levels for machine chemical feeder pumps are correct. POWER UP: To energize the unit, turn on the power at the service breaker. The voltage should have been previously verified as being correct.
CONSERVER 24LT CAM TIMER OPERATION INSTRUCTIONS The Conserver 24LT cam timer is a 2 minute, 8 cam timer with an OFF-DRAIN function. The following is a description of set points for each cam and function for each switch. CAM 1: Cam 1 is a cut cam with a single notch and serves as the Cycle/Reset. FUNCTION: When the machine is in the operation mode the notch is the home position. The machine will set idle until the door is opened, then cam 1 moves to the start position and holds until the door is closed.
CONSERVER 24LT CAM TIMER OPERATION INSTRUCTIONS (CONTINUED) SETTINGS: The left side of cam 5 must be set to drop in just past the stop point of the off/drain cam. There must be a dwell between the off/drain and the fill, so that the fill will not run while the machine is in the off state. Any adjustment made to the fill should be made with the right side of cam 5. Proper water level will be achieved when the water touches the bottom of the strainer pan.
CONSERVER 24LTP CAM TIMER OPERATION INSTRUCTIONS The Conserver 24LTP cam timer is a 2 minute 8 cam timer with an OFF-DRAIN function. The following is a description of set points for each cam and function for each switch. CAM 1: Cam 1 is a cut cam with a single notch and serves as the cycle/reset. FUNCTION: When the machine is in the operation mode the notch is the home position. The machine will set idle until the door is opened, then cam 1 moves to the start position and holds until the door is closed.
CONSERVER 24LTP CAM TIMER OPERATION INSTRUCTIONS (CONTINUED) CAM 6: Cam 6 is an adjustable cam and controls the sanitizer pump. FUNCTION: The sanitizer pump cam works off the normally closed contacts of cam 6. This requires the switch to be held open by the cam and allowed to drop into the notch to operate the pump. SETTINGS: The left side of cam 6 must be set to drop in just past the starting point of the fill cam. The adjustment for sanitizer volume must be made with the right side of the cam.
PREVENTATIVE MAINTENANCE The dishmachines covered in this manual are designed to operate with a minimum of interaction with the operator. However, this does not mean that some items will not wear out in time. Jackson highly recommends that any maintenance and repairs not specifically discussed in this manual should be performed by QUALIFIED SERVICE PERSONNEL ONLY.
TROUBLESHOOTING SECTION WARNING: Inspection, testing and repair of electrical equipment should only be performed by a qualified service technician. Many of the tests require that the unit have power to it and live electrical components be exposed. USE EXTREME CAUTION WHEN TESTING THE MACHINE. Problem: Nothing on the machine operates; power switch is on and the power light is off. 1. The circuit breaker may be tripped. Reset the circuit breaker.
TROUBLESHOOTING SECTION (CONTINUED) WARNING: Inspection, testing and repair of electrical equipment should only be performed by a qualified service technician. Many of the tests require that the unit have power to it and live electrical components be exposed. USE EXTREME CAUTION WHEN TESTING THE MACHINE. Problem: Door drops hard and will not stay closed. 1. The door spring is broken. Replace as required. 2. The door hinge is bent. Replace as required. Problem: Water flooding from the machine. 1.

ORDERING REPLACEMENT WIRE Jackson dishmachines have several color and gauges of wire used in them and it may become necessary to replace these wires. Wire may be ordered from Jackson MSC Inc., but please note that it is only available in feet. Ensure that you order the correct color and gauge.
ORDERING REPLACEMENT CONDUIT & FITTINGS/HOSE & TUBING Jackson dishmachines come with a wide variety of conduit and fittings for use in routing the wires of the machine. The list below provides for most of stock of such items. When ordering, remember that Jackson does not offer pre-cut sections of conduit for your machine, instead it is sold by the foot. Please take into account the slack that will be necessary once installing the new conduit to ensure that it fits correctly.
