GENERAL INSTRUCTIONS

(INSTALLATION)

Note: Read the following instructions carefully. Proper installation of your Conserver Dishwasher

will ensure proper machine operation.

1. Cut straps holding machine to base of crate, ease machine on to floor and move into place of installation.

2. Connect drain line to bottom of machine (2 IPS female fitting on front of machine) to conform with local and/or national codes. Drain is a gravity feed system from the machine. a. The Conserver is designed to accommodate an external scrap trap if one is shipped with the unit. The

scrap trap should be placed beneath the unit with the top opening to the right of the pump and motor mounting shelf so that the top hole of the scrap trap is in line with the drain opening from the machine.

b. Direct the drain line from the dishwasher to the top of the trap and plumb accordingly with 2" pipe of the

necessary length. Connect a 2" fitting to the back of the scrap trap and plumb to the drain line. The drain line is a gravity feed system from the dishwasher to the scrap trap and also from the scrap trap to the drain line. Scrap trap aids sluggish drains by containing machine water as it drains and letting it drain off slower.

3. Connect incoming 33/4" water line with capacity to supply 16.5 gallons per minute with a flow rate of 20 PSI at a temperature of 140°F. This connection is just before the Y-strainer. Connect to conform with local and/or national codes (standards). a. It is recommended that in areas where there is fluctuating water pressure a restrictor valve allowing 8

gallons of water per minute be installed. This will help to provide a steady fill rate. The restrictor should be located down the line from the Y-strainer.

4. Install the proper circuit breaker, wire and conduit size to conform with local and/or national codes. Refer to data plate for electrical codes.

5- The electrical connections are made to the terminal block located in the dispenser/control box on the

top of the machine. The terminal block is located on the back wall of the box with a grounding lug next to it. Three wires L1, N, and a ground wire should be passed through the hole in the back of the box and connected to the terminal block as marked.

6. Do not apply power until step #9.

7. Turn on water supply to machine; check for any leaks in plumbing and connections.

8. Place the open end of the red tube into a container of detergent; white, into a container of sanitizer; and blue, into a container of rinse additive.

9. To energize electrically, proceed as follows: a. Turn on customer's circuit breaker controlling the machine. b. Check voltage at incoming terminals L1 and N. It should match data plate voltage. Voltage at L1

should be checked to ground to ensure that a high (or wild) leg is NOT connected. (Voltage exceeding 150V to ground would indicate a high leg.)

c. If voltages are in required range, turn on circuit breaker on the side of the dispenser/control box.

10. To fill the unit with water: a. Located on the right side of the control box is a two-positioned momentary switch. To fill this unit

initially with water, push and hold the switch to the top of the unit until the water reaches the-top of the cut out for the drain opening. Release the switch and it will return to the off position.

b. After the unit is full of water, check for leaks and see if the solenoid valve opens and closes as the

fill switch is turned on and off.

c- After checking the plumbing lines for leaks, run the unit through a complete cycle to determine the

proper water level. The proper level for the water is the top of the cut out for the drain opening leading from the machine into the drain strainer and stopper. If this level is either not reached or is exceeded, please turn to the timer section of this manual to determine the proper adjustment of the timer that has to be made.

TIMER ADJUSTMENTS

The timer is a self-contained (frame-mounted) timer of the repeating cycle type. It is mounted in the control box on the top of the machine to control the automatic functions of the machine. The timer motor operates on 110 VAC, 60 cycles, taking 90 seconds to complete one full revolution. There are six micro switches which are controlled by rotating cams driven by the timer motor. Two of the cams are fixed and cannot be adjusted. The remaining four cams are adjustable and can be adjusted to either lengthen or shorten the desired operation.

Remove the power to the machine when making all timer adjustments. Included and taped in each control panel is a spanner wrench (as shown in the drawing). This wrench is

needed to adjust the cams on the timer. The cams are preset at the factory but may have to be readjusted for different conditions of the country and for the different brands of detergent, rinse additive and sanitizing solutions. On both sides of the four adjustable cams, there are holes into which the spanner wrench is placed to apply leverage to make the desired change. The left side of the cam will always start an operation and the right side will end it. The cam on the right side is the one that will be adjusted more often since this one determines the length of the operation.

When making adjustments to the timer cams, be sure that the first cam next to the timer motor is in its stop position in the notch. Place one hand over the timer motor with your thumb lodged next to or on the first cam so that it will not move when the other cams are being adjusted. To make the adjustment, place the wrench in the holes on the right side of the cam. If a longer operating time is desired, increase the gap between the left and right side of the cam. If a shorter operating time is desired, decrease the gap between the left and right side of the cam. At the extreme end from the timer motor, there is a cam marked in five-degree increments. Every four degrees equals one second of the timer's revolution.

Function of each micro switch starting from the timer motor and going left to right Timer Motor Micro Switch: controlled by a fixed cam that controls the total length of the cycle. It is

activated by engaging the fill/start switch in the start position. Detergent Micro Switch: controlled by an adjustable cam. It operates the peristaltic pump that

dispenses the detergent. By adjusting the right side of the cam, you can either increase or decrease your amount of detergents.

Drain Solenoid Micro Switch: controlled by a fixed cam. It opens the solenoid valve during the cycle that drains the wash water out of the unit.

Fresh Water Solenoid Valve Micro Switch: controlled by adjustable cam. It is important that the unit have two-and-a-half gallons of water in it during the wash and rinse cycles. The proper level indicator is the height of the cut out leading into the drain strainer and stopper. By adjusting the right side of the cam, you can either increase or decrease your water supply to meet this required level. Fill water is turned on before drain cycle ends to ensure machine is flushed before filling.

Rinse Agent Micro Switch: controlled by an adjustable cam. It operates the peristaltic pump that dispenses the rinse agent. By adjusting the right side of the cam, you can either increase or decrease your amount of rinse additive. It should activate during the fill cycle.

Sanitizing Agent Micro Switch: controlled by an adjustable cam. It operates the peristaltic pump that dispenses the sanitizer solution. By adjusting the right side of the cam, you can either increase or decrease your amount of sanitizer solution. It should activate during the fill cycle. When the timer is preset at the factory, it is set to dispense 24 milliliters of detergent, 18 milliliters of rinse additive and 16 milliliters (50 parts per million) sanitizing agent based on an 8.4% solution of Sodium Hypochlorite.

Power On Light — This light is lit all the time the circuit breaker is on.

REPLACEMENT of SWITCHES

in CONTROL PANEL

There is one two basic type of manually operated switch utilized on the Conserver dishwasher. It is the rocker switch.

Before working on the machine, it is important that the power be turned off at the customer's circuit breaker. To prevent the possibility of electrical shock, trip the breaker to the OFF position. Then turn the machine circuit breaker OFF located on the side of the control box.

The rocker switch is mounted in a rectangular hole held in position by a bracket. This switch is designed to be released from the inside and pushed outward. The spring sides must be depressed to release the switch and bracket from the hole. To remove the bracket from the switch, wedge a screwdriver in between them then lift up and move off.

If the switch is found to be defective, mount a new one into the bracket and insert it into the hole in the control box. Make sure that the tab on the switch is in the proper notch on the bracket for easy operation of the switch. Replace the wires from the used switch terminal by terminal on to the new switch.

Power can now be applied to the dishwasher and run through cycles checking all operations.

PERISTALTIC PUMP SANITIZING

DISPENSING SYSTEM

The peristaltic pumps are mounted in the Control/Dispenser Box which is attached to the top of the unit. The pumps receive their electrical signals from two sources.

The first source is the primer switch, which is used to prime the pump when it is first put into operation and then every time the agent is changed and/or the tubes are clear of any solution.

The second source is the timer, which activates the pumps during the cycle at the proper time to dispense the correct agent when needed.

If control box is locked and access to prime switches is not available, just run dishwasher through several cycles to move liquid from storage bottles to pumps.

Checkout of Sanitizing Injector The pump can be deemed operational if the following items are observed:

1. If the cam roller assembly rotates during each cycle.

2. If the solution is observed passing through the tube.

Note: Both of these operations must be observed to determine if the sanitizing agent is being

dispensed.

If it is determined that the unit is not operating correctly, the following procedures will aid in correcting the problem:

1. Make certain that the tube is in the bottle of solution. 2- Make certain that there are no cracks in the tubing and particularly in the pump hose.

3. Check ail wire connections on the pump, the timer cam, and the primer switch.

4. Check to see that there is no debris in the tubes.

5. Make sure that the tubing is inserted into the pump hose so that air is not drawn into the system.

REPLACING SEAL and CERAMIC

on WASH/RINSE PUMP

Function:

The pump is part of the total motor-pump system and utilizes one shaft seal and ceramic to prevent the pump from leaking around the impeller and shaft. One gasket is used to prevent leakage between the pump housing and the pump flange.

Replacement of Seal and/or Ceramic

1. Remove the power source to the machine by turning the circuit breaker to its OFF position on the side of the control/dispenser box.

2. Drain the system by raising the plunger and leaving it at an angle to allow all of the water to drain out of the unit. Open the petcock on the pump and drain the water from the pump into a catch basin.

3. Remove the four bolts that are holding the pump unit to the base of the machine.

4. Remove the eight bolts that hold the pump housing to the pump flange. This will eliminate having to remove the plumbing going into and coming out of the pump flange.

5. Pull the motor and the remaining pump parts away from the pump flange and plumbing. If unable to work on the pump at its present location, disconnect the wires and move it to a stable location.

6. To remove the impeller jam nut insert a screwdriver into one of the passages of the impeller and back off the jam nut with a 5/8" socket and wrench. 7- Remove the impeller by inserting a screwdriver in the end of the motor shaft to prevent it from turning and unscrew the impeller in a counter clockwise direction from the shaft.

8. To remove the mechanical seal from the shaft, place two screwdrivers opposite each other with their flat edges under the seal with the shank of the screwdrivers against the housing. Push on the screwdrivers with equal force and this will pry the seal off of the shaft.

9. After removing the four bolts that hold the housing to the motor, take off the housing and place it on a flat surface. Push out the ceramic seat and rubber cup being careful not to touch the housing.

10. Clean thoroughly the flange and housing gaskets of any scale or dirt build up. Clean the counterbore where the ceramic seat is located and the shoulder of the motor shaft that fits next to the impeller.

11. To enable the ceramic face and rubber cap to be installed in the housing squarely and evenly the counterbore in the housing and the rubber cup should be coated with a thin film of oil. Press the ceramic face and rubber cup into the counterbore of the housing using your thumbs. Apply even pressure all the way around to ensure a good tight fit, but be careful not to damage the top of the ceramic face.

12. Replace the housing on the motor being very careful not to damage or move the ceramic when

passing the shaft through the ceramic. Tighten the four bolts tightly.

13. Apply a thin film of oil to the new mechanical seal and press it into place by placing a piece of tubing

over the shaft and pushing it toward the ceramic face. The face of the seal has to fit snugly against the surface of the ceramic face. Be very careful not to allow the ceramic face to come out of the rubber cup while installing the seal.

14. Reassemble the pump and motor by reversing the procedure in steps 1-9. Close petcock on pump.

Caution: Do not operate unit until pump is filled with water.

SOLENOID VALVE P/N

0143400,115V 2 PER UNIT P/N 0143000, 220V

To Take The Valve Apart Disassembly—These valves may be taken apart by

unscrewing the bonnet and the enclosing tube assembly from the valve body assembly. See Fig. 3. After unscrewing, carefully lift off the bonnet and enclosing tube assembly. Don't drop the plunger. The "O" ring seal and diaphragm cartridge can now be lifted out.

Be careful not to damage the machined faces while the valve is apart.

To Reassemble—Place the diaphragm cartridge in the body with the pilot port extension UP. Hold the plunger with the synthetic seat against the pilot port. Make sure the "O" ring is in place, then lower the bonnet and enclosing tube assembly over the plunger. Screw bonnet assembly snugly down on the body assembly.

DIAPHRAGM CARTRIDGE

Possible Problems:

Pilot Port extension #1 clogged. Hole #2 clogged.

Remedy: Pass heated straight pin through hole #2 or clean hole #1.

INSTRUCTIONS for ADJUSTING

TENSION of CANTILEVER

Problem: Doors raise hard, but lower easily. Solution:

1. Back off (loosen) upper adjusting nuts (F) on both eyebolts (E) about two or three complete turns.

2. Tighten lower adjusting nuts (G) on both eyebolts (E) a complete turn.

3. Check door for easy operation. Adjust further, if necessary.

4. When adjustment is completed, tighten upper adjusting nuts (F) down against angle to lock in position. Check both eyebolts.

Problem: Doors raise easily, but lower hard. Solution:

1. Back off lower adjusting nuts (G) carefully, making sure there is still some thread on eyebolt available (both eyebolts).

2. Check door for easy operation. Adjust further, if necessary.

3. When adjustment is complete, tighten upper adjusting nuts (F) down against angle to lock in position. Check both eyebolts.

Problem: Doors sticking, or are hard to move up and down. Solution:

1. Raise doors.

2. Clean inside door channels on machine with a good cleaning compound. It may be necessary to remove doors to completely clean channel. If so, remove only one door at a time. Make sure cantilever has stop to prevent pulling other door up and out of channel. If it does not have stop, secure cantilever arm to machine with doors in the closed position.

3. Build-up should be completely removed so it may be necessary to use an abrasive pad (non-metallic) to clean.

4. While you have the door out of channel, make sure it is not dented or crooked. If channel is crooked or

dented, use 1/2" wide block to spread to proper opening.

5. Clean nylatron runners on the doors or replace nylatron, if excessively worn. See instructions on door runners.

6. Check door channels on machine for evenness and burrs. 7. After replacing doors, check for proper operation by raising and lowering with cantilever.

Problem: One side of door higher than other and does not close completely. Solution:

1. Straighten cantilever arm.

2. This can sometimes be accomplished while arm is on machine by forcing down on the arm connected to the high door while the other side of the cantilever is pulled up.

3. If step two cannot be accomplished on machine, cantilever will have to be removed and straightened.

APPLYING NYLATRON STRIP

to CONSERVER DOOR

It's important when removing the old door guides that the surface be cleaned thoroughly. This can be done with a solvent that will dissolve the remaining glue and/or the use of a fine sandpaper to scratch the surface where the door guide would make contact with the stainless steel door.

After this is accomplished and you are quite convinced that the surface is cleaned of all oil, glue, dirt. detergent, etc., then the door guide should be placed on a flat surface and a bed of silicone adhesive or any good non-hardening glue should be laid on the inside of the door guide's surface (top to bottom, making sure that none of the exposed surface to the outside has any glue on it).

Take the door guide and snap it over the door's edge as described in the attached sketch. Let this door set for at least one hour before use so that the glue or adhesive has a chance to set somewhat.

If these instructions are followed, the door guides should adhere to the door.

Fig. 1 - PUT A STREAM OF SILASTIC OR NON-HARDENING ADHESIVE IN INSIDE CORNER OF STRIP. Fig. 2 - SIDE VIEW OF NYLATRON STRIP. Fig. 3-SNAP STRIP ON DOOR LIP.

NOTE: DO NOT SLIDE STRIP FROM END ALWAYS SNAP ON.
