Introduction

This manual should be read and understood by everyone involved with the installation and operation of the pan washer. Keep this manual in a safe place for future reference. Extra copies or replacement copies can be purchased from the manufacturer.

Service work on the machine should be done by either a factory representative or qualified local service company. Contact the factory if the machine is under warranty.

The LVO pan washer is designed for use in bakeries, restaurants, schools, hospitals, and hotels, to clean pots, pans, bowls, and utensils. LVO pan washers are constructed of 14 gauge stainless steel (cabinets) and 12 gauge stainless steel (framework). The interior piping, rinse system, wash arms, and screens are stainless steel. Because of its sturdy construction, it will deliver years of powerful, thorough cleaning.

The machine is equipped with a heating element in the rinse tank to boost the rinse water to a sanitizing 180°F at the inlet to the machine. A rinse tank heated with recirculated steam is an option available on some models.

The wash tank on electric models incorporates a 9 kW electric heating element for heating the wash water. The gas models use a series of (2) 24,000 BTU infrared burners. Steam models use either a direct injection system or a recirculated steam heating coil.

The pump recirculates wash water at approximately 55 pounds per square inch of pressure.

Each machine is equipped with two safety switches. The first is a low water cut-off, which shuts the machine off when the water level in the wash tank falls below the required level. The other safety device is a door switch, which prevents the machine from operating when the door is not completely closed. An electrical schematic for your machine is posted inside the control box cover.

Detergent Feeders

This machine must be operated with an automatic detergent feeder, which is supplied by the customer, including a visual means to verify that detergent is delivered or a visual or audible alarm to signal that detergent is not available for delivery. Power for the feeder can be provided by the pump supply connection in the control panel. See feeder equipment manual for additional information.

Installation Instructions

Step 1 READ: Read and understand these instructions thoroughly before attempting any part of the installation process.

WARNING: Not following these instructions may void warranty, cause damage to the equipment and/or cause injury to anyone involved in the installation or operation of this machine.

A copy of the installation instructions and start-up procedure is printed on the sheet attached to the side of the machine. EVERYONE involved with the installation must be familiar with all aspects of the installation procedure.

Step 2 POSITIONING: The factory recommends leaving as much room as possible around the machine for future service work. No less than 16” should be allowed along the sides of the machine (36” for side with control box), and no less than 12” between the rear of the machine and the wall. Extra room around the machine will facilitate cleaning the washer area.

Step 3 UNCRATING: Leave the machine fully crated until the washer is placed in the location where it is to be installed. After the washer is uncrated, remove the banding that holds the door weight stationary on the back of the machine. This will allow the door to open. Inside you will find the accessories for the machine. Among these will be the fan (if ordered) and the legs. Remove the machine from the pallet, install the legs, and level the machine. The legs are adjustable by turning the small end one way or the other.

Step 4 DRAIN: Provisions for the drain should be made next. The pan washer has a copper drain located as shown on the drawings (see specifications page for drain size). The drain should be plumbed according to local code. Local ordinance may require a grease trap, vent, and/or a floor sink. If required, these should be installed before the machine is installed. It is strongly recommended that unions be used to allow the machine to be easily moved. Failure to do so may void the warranty.

Step 5 WATER SUPPLY HOOK-UP: The factory recommends 140°F hot water at the machine (see specifications page for water line size). This may require a dedicated water heater for the pan washer. If hard water is present, the manufacturer recommends installing a water softener or calcium filter. Hard water deposits will shorten the life of many of the components on the pan washer, resulting in higher maintenance costs. Please note that a union is installed at the point of hook-up (see drawings). This will allow the machine to be moved for service and cleaning. The customer must furnish a shut-off valve on the supply side of the union. This

shut-off should be easily accessible to the operator of the machine. Additionally, if the machine is located a long distance from the water main, it may be necessary to supply a larger line to the machine to insure proper water pressure and flow for the machine to operate correctly.

Step 6 STEAM VENT: The machine is equipped with a collar for 6” duct work as shown on the drawings. This duct should be directly vented to the outside of the building. DO NOT vent into a wall, attic, or any other concealed space of the building, and avoid horizontal runs of duct.

The factory recommends 6” plastic pipe or stainless steel duct for the vent. If stainless steel is used, the duct work should be installed with reverse joints so that the condensate inside the vent can drain back into the machine without leaking, and all seams should be sealed with silicone sealant.

Generally, the machine will ship with fractional hp inline fan option. This fan should be mounted and sealed with silicone directly into the two adapters sent with the fan with the side with the fan blade pointing up, and the adapter into the flange on the top of the machine before the ductwork is installed. The longer 12” adaptor should be placed between the machine and the fan, with the shorter 3” adaptor placed into the discharge side of the fan. The fan is powered from the control circuit. Wire is provided to connect the fan to the two terminals marked “FAN”

The fan is designed to run at two different speeds. The lower speed is to remove excess steam from the machine during the wash cycle, which is determined by the speed control located inside the panel. The speed control should be set so that it just removes any steam coming from around the door when the machine is running fully loaded. The higher speed is controlled by a timer and runs at the end of each cycle and when the door to the machine is open.

Note: Consult the factory before connecting any fan not supplied with the machine.

While the machine is designed to be directly connected to a vent, local or state codes may require a hood to be installed. Always check the local regulations prior to installing the vent.

Step 7 ELECTRICAL CONNECTIONS: The electrical connection to the machine should be made by a qualified electrician. All steps should be taken to insure that the supply voltage to the machine is the same as the rated voltage of the machine. Also, check that sufficient amperage is supplied to the machine (see specifications page for ratings).

A main power shut-off, supplied by the customer, must be installed near the machine in a place easily accessible by anyone operating or servicing the machine. The line from the main shut-off to the machine should be watertight flex conduit. The factory strongly recommends that a few extra feet be used to allow the machine to be moved if necessary. The wire used to supply the machine must be heavy enough to carry the amperage load of the machine. The supply should be run into the back of the machine at the bottom, between the rinse tank and the side of the machine, and through the back of the control box.

The first connection should be the main ground to the grounding lug at the lower right hand corner of the control panel. Next, the hook-up can be made to the main power block.

Once the hook-up is complete, the circuit breakers in the control box of the washer must be checked to make sure they are in the “OFF” position. The main switch on the wall can then be turned on to power the machine.

Step 8 GAS CONNECTION (Gas Machines Only): A certified gas technician is required for the hook-up and final adjustments of the burners. This is necessary to insure proper inlet and manifold pressure for the gas machines (see spec page for gas pressure settings).

Verify the type of gas supply to be used, either natural or LP, and make sure the marking on the gas data plate agrees with that of the supply. The gas line hook-up must be made with a union at the location shown on the gas machine drawing (see spec page for gas line size). This line must have a shut-off valve (supplied by the customer) installed near the machine and accessible by anyone operating or servicing the machine.

A 3” stainless steel gas chimney runs up the back of the machine. A draft diverter is included with the machine (shipped inside the machine with the other accessories). The draft diverter must be installed on top of the factory installed chimney. The Type B gas flue can then be continued to the outside of the building per local codes.

The initial start-up of the burners should not be done until the start-up procedures for the machine on the following pages have been completed.

Step 9 STEAM CONNECTION (Steam Machines Only): A steam line is required to supply the steam injector or recirculated steam heat exchanger coil (see spec page for size of steam line). A strainer is already built into the machine but a union will be required in the supply line (supplied by the customer). The specification sheet above lists the rated pressure and average steam consumption rate for the machine.

Startup Procedures

Warning: These instructions must be followed or damage to the machine will result.

Step 1: Close drain valve. See drawings for location.

Step 2: With the circuit breakers in the control panel of the machine in the “OFF” position and the main power supply to the machine connected, the ON-OFF switch on the button panel can be turned to the “ON” position. Then wait approximately 5 seconds for the machine controller to power up.

Note: The amber power light will not turn on until there is sufficient water in the machine.

Step 3: Fill the machine by pressing the Auto Fill button. The machine will continue to fill for 90 seconds past the point where the low water protection device is energized, turning on the power light and temperature controllers. The machine is equipped with a low water protection device and will not run without sufficient water in the wash tank.

Note: The machine has a door switch and will not operate with the door partially open.

Step 4: With the machine full of water and with the door closed, press the start button and let the machine go through a complete cycle. The timers in the control panel will go through their sequence, lighting the wash and rinse lights on the front of the machine. The cycle is complete when the red light goes off and the amber light stays on. The pump will not run at this time because the pump circuit breaker in the control panel is in the “OFF” position.

Step 5: Repeat Step 4 at least two times or until water can be heard spraying out of the rinse nozzles. This ensures that the rinse tank is full of water before the heating element is energized.

Step 6: All circuit breakers in the control panel can now be switched to the “ON” position. This will energize the heating system in the wash and rinse tanks.

Step 7: Check the pump for proper rotation by pressing the start button and observing the wash pressure gauge on the front of the machine for 5 to 10 seconds. Then press the stop button. The wash pressure should be 45-60 psi. If the pressure is erratic and only rises to about 20 psi, the pump is running backwards. The pump will also have a noticeable growl when running backwards. Disconnect power to the machine and reverse the outside two wires that feed the power block in the control panel. Reconnect power and run the pump again to confirm that it is operating correctly.
