DISHMACHINES
PREPARATION FOR INSTALLATION
When you receive your new CMA-44, complete the assembly by installing the curtain rods and two
buffer sections which are shipped inside the machine. After the shipping crate has been removed from
the machine, remove the left and right stainless steel buffer sections and bolt them in place with the nuts
and bolts provided. The buffer with the extra curtain clamps mounts onto the dirty end of the machine.
All of the spray arms should be inserted and locked in place over the wash tank compartments. Make
sure that the end caps are in place.
There are a total offive curtains used in the CMA-44; two are long and three short. Two of the long cur-
tains have shorter rods than any of the other curtains. The short rods hold the long curtains at the
entrance and exit of the machine.
If the dish flow is from left to right, the proper sequence for the placement of the curtains would be long
curtain, short rod, in the first station; short curtain, short rod, in the second station; short curtain, long
rod, third station; short curtain, long rod, fourth station; short rod, long curtain, sixth station. The only
curtain change to reverse the flow of dishes is that the short curtain #2 changed to #5. The sketch
below lists the stations 1 through 6. In this case, it represents a flow to left to right. Reverse the se-
quence for right to left dishmachine.

DISHMACHINE FRONT VIEW
The CMA-44 is designed to give maximum cleaning in 44 inches. It represents the cleaning power of
machines twice its length. The curtains incorporated in the machine minimize transfer from tank to tank
during the wash and sanitizing procedures.
Energy costs for running the CMA-44 have been greatly reduced by the introduction of stage washing.
This design allows the heavy food soil to be removed in the first station which provides a relatively clean
dish before it reaches the wash stage in the center tank.

CMA
INSTALLATION NOTES
DISHMACHINES
1. Tables must slant into machine (for 28" of Table we recommend a drop of at least 3/4" in table
height).
2. Tray rail is not to be moved up or down. Any change will alterthe position of the Tilt Switch in relation
to the dish rack or the dish rack in relation to the conveyor dogs.
3. Use wide angle 90 degree plumbing for scrap trap (to avoid debris from blocking the scrap trap
drain). This could result in flooding the machine.
The scrap accumulator
is plumbed to the two inch exit on the entrance side (or dirty dish side) of the
machine. The machine
is designed to deliver .8 L.T./.94 H.T. gallons of fresh rinse water which carries
from the rinse and power wash tank, into the pre-wash tank and then exits out into the scrap accumulator.

4. Observed rotation of the Conveyor Cam.
• If rotation is clockwise as you are looking at the machine from the front, that is correct.
• If it is counter clockwise, the movement ofthe rocker arm will unscrew the cam bearing.
•
To change rotation switch any two wires at motor.
• See (below right) for conveyor speed cam locations.
5. Water pump motors should be wired as such:
*Caution -motors are 3 Ph. Checkrotation. Motors must turn clockwise looking at shaftfrom back
of motor. Remove dustcap on back of motor to check rotation of motor shaft.
6. Incoming wire for the CMA-44 should be at least an 8 gauge wire for L1, L2 and L3. Connect highest
voltage wire (stinger) to L-2.
7. If tables enter conveyor machine at a 90 degree angle and buffer or splash shield cannot be used,
modify shield by cutting on a diagonal. It will provide some protection from spla~h.

8. Make sure that all racks used will press lever switch down -far enough to activate. If they DO NOT,
adjust tray track so that the racks will.
9. No Quick Drains should be installed on tables before orafter machine. They must be plumbed back
into machines or welded over and capped off.
10. The diagram below should be viewed as though looking at from the inside of the machine. The dia-
gram indicates proper tilt switch adjustment. Adjust cam to activate micro switch, when trip switch is
level with tray track.
NOTE: If not adjusted properly, Final Rinse will tum off and on several times when dish rack re-
leases tilt switch and it rocks back and forth.

11. The water inlet is attached to the inlet line of the top of the machine with a three-quarter inch, 140
L.T., 180 H.T. degree hot water supply.
NOTE: Make sure that the primary heater is set to deliver 140-150 degrees to the machine. If un-
sure, turn down the booster heater to 140-150 degrees and leave it on line. Be sure the water
source is 3/4" inlet all the way from water heater or water softener. No 1/2" restrictions. The High
Temp machine comes with two incoming water line connections. One is for the final rinse at 180°F
and the other is to fill the machine 140°F. *High Temp must be 180°F water supply to final rinse
valve and an additional 140°F supply line to machine fill valve.
12. Set Pressure Regulator while machine is in FINAL RINSE CYCLE; correct pressure is 20 psi(+ or-
2 lbs.) VERY IMPORTANT.
13. The diagram below shows the proper spray arm alignment to prevent tank to tank contamination
and excessive spray reflecting out of machine. *See #7 under Regular Service & Maintenance

ELECTRICAL POWER REQUIREMENTS
DISH MACHINES
CMA-44 requires 208-230 volt, 3 phase power. Connect the wire that indicates the highest voltage
(stinger lead) to L-2 powerblock connection.
Install CMA-44 Conveyor on a clean 40 amp breaker.
*IMPORTANT: Check that motors are turning in the correct direction. Looking at shaft of motor on the
back side, it shouldbe turning clockwise. If one or both pump motors are turning in the wrong direction
switch L-1, L-2 & L-3 wires untilcorrectdirection is found.
CMA-44 HEATER
The 10 Kw, 3 phase heater is located in the wash/final rinse tank. The heater has an independent
power switch which is activated when ready for operation. If one was to drain the tank and leave the
heater on, the thermostat would receive a signal to shut down from the float switch, located along side
heater in the rinse end of the tank.
* We do recommend that the heateris shut off when machine is not in operation.
Thermostat is located behind stainless cover on final rinse side of machine. There is a thermostat ad-
justment access hole located on this cover.

SAFETY TIPS FOR CMA-44
Always turn off circuit breaker at wall when working on dishmachine. (Remember it is
220 voltage.) Even with machine switched off there is a live connection coming to the
switch so switch off circuit breaker.
Do not get in path of conveyor rocker arm and the conveyor moving bar. Do not reach
into rocker arm area without first making sure the dishmachine is turned off at the cir-
cuit breaker.
Do not open front doorwhen machine is in operation. -
Avoid water spraying on electrical control box on top of the dishmachine. When
cleaning, do not spray water directly on to motors.
When cleaning final rinse arms that are plugged, exercise caution when removing.
The final rinse arms are under pressure and filled with chemicals.

B. Turn on circuit breaker from power source. Turn ball valve on and fill machine until overflowing out
pre-wash tank.
C. Turn heater switch on an make sure water temperature is between 140-150 degrees. Tank heater
will hold temperature at 140° if final rinse is providing 140°-150° at all times (Low Temp) and 150°-
1600 for High Temp if final rinse is maintained at 180°.
D. IMPORTANT
Placement of dishes in rack:
Make sure dishes are placed correctly. If they become dislodged, they could interfere with lever tilt
switch and interrupt the operation of the machine.
---RACK TRAVEL--.,..
E. At the end of the day and after heavy periods of accumulation, clean strainer trays. There are 5
trays inside the machine. Also, remove six spray arms and clean them out. Remove these and
clean, then take caution in returning to holding tracks in tanks.
*When waterbecomes heavily soiled, drain tanks and refill machine.
F. Check chemical buckets. Make sure there is adequate supply of detergent, rinse aid, and sanitizer
(LT.). Also check that pick-up line is inserted into correct bucket.
G. Activate trip switch on pre-wash end of machine. The 60 sec. time delay-off relay will lock the
machine in the run position for 60 sec. then shut-off. This delay-off relay can be adjusted from
0-60 sec. This relay prevents machine from running when flight of dish racks are not in machine.

The rinse and sanitizing agents are not injected during the initial fill stage. They are injected into the final
rinse make-up water when the tilt switch is activated in the final rinse tank.
CHEMICAL DISPENSING: Low Temperature Application.
See BETA operational instructions for sanitizer adjustments for Low Temp applications.
The BETA sanitizing pump operates when the fresh water enters the machine during final rinse. The
water is treated at 50 ppm. The CMA-44 is adjusted with the pressure regualtor to 20 pounds pressure,
+ or - 2 lbs. This allows .8 (L.T.)/.94 (H.T.) gallons of water to enter the machine each time a rack is
washed.
It is recommended the 5-1/2% chemical solution be standardized to allow uniform dispensing of the
sanitizing solution into the flow of rinse water as the machine operates. At this level, maximum shelf life
is available.
Inside the control box is a labeled power block for sanitizer and rinse aid which is powered when the
final rinse tilt switch is activated. The detergent power block is labeled and provides power when the
conveyor and pump motors are operational.

CMA
DISH MACHINES
1. Upon entering the facility, make a preliminary check of the flatware and glasses, especially
stemware. This will give you a quick indication of how the machine is functioning.
2. Go to the CMA-44, turn off the circuit breaker providing power to the machine. Open the door and
check the interior condition of the machine.
a. The stainless on the inside of the machine should be clean and shiny, no dull look or buildup of
white lime scale.
b. Checkthe condition of the scrap trays for excessive garbage. Make sure the machine operator is
cleaning the machine, explain proper cleaning procedures. ·
c. Open the drains and check to make sure they are all working properly.
3. Once the machine has drained, remove both end curtains from the scrap and rinse and remove all
the scrap trays from the machine. A. Check all spray arms and jets -clean and explain cleaning
procedures to dishmen. B. Check the drain openings making sure they are free and clear of debris.
C. Check the heater element. It should be black with no splits, breaks, or cracks.
4. Close the drains, turn the power on and fill the machine.
a. Checkfill vacuum breaker for leaks.
b. This is a time to check the water hardness. Check the water at the fill while it is coming into the
machine.
c. Using a curtain bar or something long, tum on the final rinse and observe the spray pattern of the
final rinse jets. It is easier to see while the pressure is lower. If you have any clogged rinse jets,
clean them using a bent paperclip.
5. Check the heater to see if it is working. If the temperature is below 140 degrees, check the
thermostat setting .. Also check that the heater contactor has activated. The contactor plunger should
be in the PULLED-IN position. Check that the float switch is working properly.
6. With the machine full, replace all of the scrap trays into the proper position.
7. Place a rack into the machine, and observe the spray pattern of the scrap, the wash, and the final
rinse.
*The CMA-44 has an excellent feature about it which is helpful in checking the spray pattern.
The wash pump motors and the conveyor motor can be operated independently from one
another by pushing the test switch located on the top of the mag starters. Disarm one mag
starter at a time and observe the spray arm spray pattern for needed adjustments.
By disarming the conveyor motor while a dishrack is in the final rinse section this makes
it convenient in setting the chemical levels.
a. Checkthe titration of the wash tank at this point.
b. While the rack is in the final rinse, check the chlorine for 50 ppm in the final rinse.
c. Observe final rinse vacuum breakerfor leaks.
8. Run a stemware or glass rack through the machine at this point and check the results on the glassware.
A. Observe the check valves for the rinse and sanitizer. Make sure they are not leaking or building
up chlorine crystals. If they are clean, leave them alone. B. Check the condition of the chemical
tubing from the peri pump to the check valves. C. Check the peri pump squeeze tubes to make sure
they are tight, pumping product properly and not leaking within the peri pump. There should be no
moisture within the peri pump itself. D. Observe the final rinse pressure at 20 psi ±2. Adjust if
necessary.

MA
REGULAR SERVICE & MAINTENANCE CHECK LIST
I
9. Check the condition of the chemical tubing coming from the detergent rinse and sani buckets, up to
the machine.
10. With the machine stopped, check the roller cam bearing on the conveyor. You should be able to
move the outer cover of that roller cam bearing with your finger. Also, keep it well greased so that
outer covering does notfreeze up.
11 . Check the conveyor system. Make sure the complete system is running smoothly.
12. Run two or three racks through the machine. Check the scrap overflow. While the racks are running
through the machine, take a quick look under the machine to check for any drips or leaks coming
from the machine or motorto make sure a pump seal is not leaking.
13.*Run a rack through the machine and check if 60 sec. off delay relay is operating properly. If relay is
set for 60 sec., machine will shut off 60 sec. after final rinse trip switch is de-activated. If 60 sec. off
delay is notworking, there is an override switch located on the back of control box.
14. Run a rack through and check if power activating trip switch is operating properly. This trip switch is
located on pre-wash end of machine. The trip switch activates a reed switch that is mounted on the
outside of the machine underthe dish table.
15. Using an all-purpose cleaner or stainless steel polish, clean up the outside of the machine to keep it
looking nice.
16. Once this is done, fill out a service report and take your results to the manager.
This is a quick, preliminary check of the machine that should be done at least once a month on a regular
scheduled service call with a serviceman or a scheduled appointment with a salesman going in. All of
this checking does not require much in the way of tools. About the only extra item you need is a chlorine
test kit or a detergent test kit. The above can be accomplished in 10-15 minutes.

SPECIAL TOOLS NEEDED IN SERVICING THE CMA-44 CONVEYOR:
Electrical Test Equipment
1. Voltage/ohms tester
2. Amp probe
Hand Tools
1. Small snap ring pliers
2. Mechanical fingers (flexible or rigid)
3. Thermometer
4. Allen wrench set
5. variety of hand tools
TEST TO RUN
Heater Circuit 10 Kw 3 Phase heater should read 21 amps on any of the three wire connections.
Tilt Switch If a tilt switch becomes loose and inoperative, it will be necessary to remove it by taking the
snap ring from the shaft after the cam has been taken off. Then the tilt switch can be pulled from the
inside after which the bearing and brass sleeve can be tightened or replace.
Elect All controls in the CMA-44 conveyor are operated with 208/230 voltage. The power supply to the
three motors and heater element is 208/230 voltage three phase.
Thermostat If it become necessary to adjust the thermostat, it can be done by removing hole plug on
heater cover and turning set screw clockwise to increase. Heater cover is on the final rinse side of
machine tank.
Best results are obtained if line water temperature at machine is 150 degrees F for Low Temp and
180°Ffor High Temp. ·
If all tests have been made and all components are satisfactory, a solution (if an answer still has not
been found), may be a loose connection or poorly crimped wire. This will keep full power from reaching
the motor or heater.
When testing for voltage in the CMA-44 conveyor, start at the power block and follow down to the end
(defective item). When you lose a voltage reading, you have found your problem.
Final Rinse Arms Recommend keeping extra rinse arms on service trucks, in case of ha.rd water
clogging, soak clogged arms in a delimer back at shop.
