1.2. PKD24A Operational Cycle

The PDK24A Operational Cycle has a total cycle time of 2 minutes (120 seconds). The Timing Diagram and the steps listed below detail the individual functions that are executed during each Operational Cycle.

Seconds: 0 10 20 30 40 50 60 70 80 90 100 110 120

1. With the machine powered on, toggling the START switch begins a cycle. a) Toggling the START switch energizes both the cam timer motor and the instant

start relay. The instant start relay latches ON the power to the cam timer motor so that the START switch can be released a moment after it has been toggled without the cam timer motor losing power.

b) After about 2 seconds, Cam 1—the Start cam—latches ON the power to the cam

timer motor and drops out the instant start relay. The cam timer motor continues to run for a total of 2 minutes, at which time it switches OFF—resetting the cam timer—and waits for the next start command.

2. Cam switch 7 controls the pump motor. The pump motor comes ON at the beginning of the operational cycle and continues to run until the end of the drain function (controlled by cam switch 3), at which time it turns off for about eight seconds allowing time for the machine to refill enough to avoid running the pump dry before the pump motor restarts and runs to the completion of the operational cycle.

PKD24A INSTALLATION & OPERATION MANUAL Rev. 11.09 PAGE

The pump motor runs the pump for the 57-second wash cycle, then pumps the water out through the drain, turns off for about 8 seconds (allowing the machine to refill with clean rinse water) and then runs the pump for the 48-second rinse cycle.

3. Cam switch 3 controls the drain function. At the end of the 57-second wash cycle, cam switch 3 energizes the drain valve solenoid allowing the pump motor to drain the wash water out of the machine. Cam switch 3 also increments the rack counter by one each cycle.

4. Cam switch 4 controls the water valve solenoid on the water supply to flush and fill the machine. At the end of the wash cycle the drain valve is opened, the pump motor continues to run (to pump the wash water out through the drain), and the Flush function begins. At first, flushing the machine because the drain valve is still open, then—with the drain valve closed and the pump motor stopped— the machine begins to fill for the rinse cycle. Once the machine has refilled sufficiently, the pump motor restarts carrying out the rinse portion of the cycle as the filling of the wash tank completes.

5. Cam switch 2 controls the detergent pump and turns ON about 5 seconds after the operational cycle is started and runs for a few seconds to provide sufficient detergent for the wash cycle. This cam can be adjusted as necessary for proper detergent dosage. See section 4.1.1 Cam Adjustment

6. Cam switches 5 and 6 control the sanitizer and rinse pumps respectively. They turn ON at the beginning of the rinse cycle and run for a few seconds to provide sufficient sanitizer and rinse aid for the rinse cycle. These cams can be adjusted as necessary for proper chemical dosage. See section 4.1.1 Cam Adjustment

7. Cam switch 8 operates the sustainer heater. This cam assures that the sustainer heater only turns on when the dishmachine is not in a cycle. This prevents the machine from drawing too much electrical current at any one time.

Getting Started

2. Getting Started

2.1. Introduction to the PKD24A

The PKD24A Glasswasher is unique in its field; it has all the features of a standard commercial size machine packed into an under-counter, standalone glasswasher.

Operation of the PKD24A is extremely easy. After initially filling the machine (see section 3.1.3

Filling the Machine), pressing the rocker Fill/Start switch to the “START” position begins the

operation cycle, which runs automatically. To reduce service time, all electrical components are mounted in a sliding drawer for easy access.

This “Works-In-A-Drawer” can be removed by disconnecting wires on power block. The only external connections necessary are the power source, water supply and drainpipe. The optional sustainer heater with thermostat is extremely practical for maintaining wash tank

temperature between cycles. The 1250-watt heater will hold the wash tank temperature between 130°F and 140°F when machine is not in operation.

The supply water to the PKD24A must be a minimum of 140°F. The pipe supplying the water must

be ½” minimum. The plumbing connection is located at the back of the machine. The drain is a 1"

NPT fitting located at the back of the machine for easy attachment of your drain hose. See section

2.2.2 Plumbing. This manual is structured to provide a complete reference guide to the PKD24A. It is presented in

a manner that all users will be able to comprehend and use as an effective tool in supporting the installation, operation and maintenance of the glasswasher. The first section provides the specifications and details of the operational cycle. The next section explains how the machine is packaged and what to look for when receiving the machine. After unpacking the machine, this manual explains how to install and set up the machine for use. Requirements are given for plumbing, wiring, and space considerations. Our well-trained sales representatives prior to the order being placed always take these attributes of the machine into consideration. In the manual, guidance is also given for operation to ensure that the machine will be able to run optimally.

The Operation section of the manual may be used for instruction and procedures when required. We make this portion of the manual easy to understand so that all levels of operators may be able to read and comprehend the operation of the machine. The function of the machine itself is mostly automatic and takes little training to put into full operation. The Operation section also includes diagnostic considerations for the machine if problems occur.

The Maintenance section of the manual is for qualified personnel and provides trouble shooting procedures and specific maintenance instructions.

The final section of the manual is the Parts Manual. This section has the parts lists and wiring diagram for the machine.

Perlick warranties the workmanship of the machine. At Perlick we are committed to providing the best machines and customer service in the food and

beverage industry and your feedback is welcome. The Q.C. form found in each machine has a section, which we encourage you to fill out for feed back regarding the equipment.

MODEL PDK24A INSTALLATION & OPERATION MANUAL Rev. 11.09 PAGE

Getting Started

2.2. Receiving and Installation

The glasswasher is shipped from the factory in a corrugated box on a wooden pallet. The installation guidelines give a systematic procedure for setting up the machine.

1. Start by removing the box and packaging material. Check for the following component parts:

A. Drain Screen:

The Wash Tank Scrap Screen is shipped inside the wash cavity of the machine. This screen must be in place during operation. It has been designed to perform two basic functions:

Strain water that is circulating through the spray arms and pump assembly. A basket to catch heavy solids or broken glass that could plug the pump.

B. Spray Arms

The end caps on the spray arms have been caped to protect them in shipping. Remove the cap from the spray arms.

C. Tube Stiffeners:

The tube stiffeners must be used to prevent the feed tubes from curling up inside the chemical pail allowing the tip to rise out of the chemical. Remove the tie-wraps securing the tube stiffeners to the dishmachine to free them up for use.

2. Set the machine in place and, using the leg adjusters, level from side-to-side and front-to-back

(VERY IMPORTANT).

2.2.1. Electrical*

A 20-amp, 115 volt, 60 Hz dedicated circuit must be used to supply electrical power to the PKD24A machine (see specification sheet page 2). The power connection must be such that there is sufficient length of flexible conduit to permit the machine to be moved for cleaning.

2.2.2. Plumbing*

The machine is equipped with a gate valve with a ½” female NPT connection located at the lower

left-hand corner (facing the back) of the machine. A 140°F water line should be plumbed to this point. The water line used must be of sufficient length and flexibility to permit the machine to be moved for cleaning.

A 1” male NPT fitting is provided for the drain connection on the discharge port of the diverter valve (lower, right-hand corner of machine). This fitting may be removed and user provided hardware might be used if necessary to facilitate compliance with local plumbing codes. Code requires that the drain discharge provide an air gap no less than 1” or two pipe diameters; whichever is greater, above the flood level rim of an approved floor drain.

2.2.3. Post Instructions

Mount the wall chart provided where it can be easily viewed and instruct the operators on proper cleaning and operation of the PKD24A. The instruction chart is also provided as an appendix to this manual (see appendix 1).

Electrical and plumbing connections must be made by a qualified person who will comply with all

available Federal, State, and Local Health, Electrical, Plumbing and Safety codes

3. Operation

3.1. Initial Setup

3.1.1. Check…

 Drain screen is in place  Spay arms and end plugs are secure

3.1.2. Chemicals

Assure there is a sufficient supply of chemicals before beginning a shift.

3.1.3. Filling the Machine

With the power ON, press and hold the Fill/Start switch in the “FILL” position

until the water level in the wash tank is about 1” deep, for best results use

water level indicator located at the back of the wash tank.

3.2. General

Caution: Do not operate the dishmachine without the drain screen in place. Debris

getting into the pump impeller can damage the pump.

1. Load a rack of glass into the machine and close the door.

2. With the machine filled to the proper level, press rocker Fill/Start switch to the “START” position – the machine will automatically begin its cycle. The green running light on the switch will illuminate while an operational cycle is in process.

3. At the end of the shift, drain the machine by holding the Drain rocker switch in the

“DRAIN” position until the machine is completely drained. To avoid running the pump dry, do not hold the Drain rocker switch in the “DRAIN” position any longer than

necessary.

4. Remove and clean the drain screen. Remove and clean the spray arms. (See wall chart instructions).

5. Replace the drain screen and spray arms.

3.2.1. Pre-Scrapping

It is essential that the operator thoroughly understand the importance of pre-scrapping the glasses before loading them. The PKD24A is equipped with a removable drain screen. The drain screen can be easily removed for cleaning between Operational Cycles of the dishmachine. Properly pre-scrapping the glasses should permit the glasswasher to operate for an entire shift before needing to remove and clean the drain screen.

3.2.2. Proper Chemical Dosage

The amount of chemical delivered, whether it is detergent, sanitizer or rinse aid, is determined by its respective cam on the cam timer.

Cam number 2 runs the detergent pump Cam number 5 runs the sanitizer pump Cam number 6 runs the rinse aid pump

These cams were set at the factory but must be adjusted after final installation to maximize efficiency of chemical use (see section 4.1.1 Cam Adjustment.)

Operation

MODEL PDK24A INSTALLATION & OPERATION MANUAL Rev. 11.09 PAGE

Operation

3.2.3. Proper Filling

The number 4 cam determines the amount the machine is automatically filled each cycle. When the number 4-cam switch actuator rides down into the cam groove, the solenoid valve on the fill line is energized causing the machine to fill. Since the cam only controls the duration of the fill, varying water pressure can vary the amount the machine fills. If the water pressure at the facility where the machine is installed is higher or lower than the water pressure was at the factory, the number 4 cam may need to be adjusted to correct the difference (see section 4.1.1 Cam Adjustment). The machine should be filling to a level about 1” deep over the entire bottom of the wash tank, or just below the lower wash arm. If the water pressure at the facility varies throughout the day, a pressure regulator may have to be installed on the water supply line to the machine to maintain constant pressure.

Note: The tank must be properly filled, and the machine properly leveled, or the float switch, which prevents the heater from turning on if the level is too low, will not permit the heater to turn on.

3.2.4. Water Pump

The water pump takes in water from the drain sump and pumps it to the spray nozzles at a rate of 35 gallons per minute and a pressure at the nozzles of approximately 7 to 10 PSI. After being released through the spray arms and washing or rinsing the dishes, the water runs down the pan to the sump, through drain screen, and back to the pump.

A 115-volt, 1 HP motor operating at 3450 RPM, drives the pump. The impeller is mounted with a right-hand thread onto a 5/8” stainless steel shaft, which is coupled to the motor armature shaft.

3.2.5. Pump Cavitation

By listening to the normal pumping sound of the motor it can be determined if there is insufficient water in the machine, as you will hear a hesitation in the normal pumping rhythm, which is created by the air getting into the pump. Cam 4 can be adjusted to increase the amount of water that is automatically fed into the machine during a cycle (see section 4.1.1 Cam Adjustment).

Maintenance

4. Maintenance

The maintenance procedures detailed in this section are to be performed by qualified personnel.

4.1. Timer assembly

The standard timer assembly consists of a (2 minutes per revolution) motor turning a common shaft, which, in turn, rotates eight cams. As the cams rotate, they control various functions and the sequence of the operational cycle.

A label on the timer assembly identifies the individual function of each of the 8 cams. Cams 1 through 8 are positioned from left to right beginning with the “START” cam (cam 1).

Timer Assembly Label

Except for cams 1, and 3, all other cams can be user adjusted. The cam positions are all set at the factory and only the cams controlling the chemical pumps (cams 2, 5 & 6) should ever need adjusting. Each micro switch on the timer assembly is turned on and off by the cam its actuator rides on. For all of the cams, except cams 1, 7 and 8, its corresponding switch is ON when its actuator is down in the cam groove. (Cams 1, 7 and 8 are reverse acting and are turned ON when the micro switch actuator is up out of the groove.) Opening the groove of any cam other than cams 1, 7 or 8 will increase the amount of time that the micro switch is held ON. The cams are slip-fit and a cam adjustment wrench is provided (a small screw driver or the edge of a table knife can also work to adjust the cams).

4.1.1. Cam Adjustment

The two sides of each cam connect to the shaft with a slip-fit so all cam adjustments are made by rotating one side of the cam on the shaft to either increase or decrease the size of the cam groove.

1. Turn off the circuit breaker providing power to the machine before accessing the timer assembly.

Caution: One of the terminals on the main power switch remains “hot” even when the machine’s main power switch is turned off—so turn the power off at the circuit

breaker.

2. Remove the two screws securing the front lower panel.

3. Using the timer assembly label, determine which cam is to be adjusted. Double check by counting over from cam 1 to the cam to be adjusted.

4. Determine which edge of the cam groove to be adjusted is the leading edge (contacts the limit switch actuator first when the shaft is rotating) and which edge of the groove is the trailing edge. The leading edge of the cam groove determines when in the cycle the control action begins and should not be changed.

5. Adjust the trailing edge of the cam groove by rotating the appropriate side of the cam

in the proper direction to either increase or decrease the cam’s groove; resulting in

increasing or decreasing the total time that switch will be held ON.
