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.
MODEL GL-X INSTALLATION & OPERATION MANUAL Rev. 1.00A –08/04/05
PAGE3
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 GL-X
The GL-X 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 GL-X 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 GL-X 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 GL-X. 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.
CMA warranties the workmanship of the machine.
At CMA 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.

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 GL-X
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 GL-X. 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

Operation
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
•
3.2.
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, or just below the
bottom wash arm.
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 GL-X 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

Operation
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.)
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. See section Error! Reference source not found. Error! Reference source
not found. for a detailed drawing.
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).

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.

surfaces of the utensils when they are properly racked. These parts shall be thoroughly cleaned at
least once each day. The pumps and the wash and rinse sprays or jets shall be designed that a
forceful stream of water will reach all surfaces of the utensils when they are properly racked. These
pars shall be readily accessible for inspection and cleaning.
“After bactericidal treatment, utensils and containers shall be stored at a sufficient height above the
floor in a clean, dry place, protected from flies, splash, dust, overhead leakage and condensation,
and other contamination. Containers and utensils shall be inverted, covered, or otherwise protected
from contamination until used for serving.”
Drain racks, trays and shelves shall be made of non-corrodible material and shall be kept clean. In
handling containers and utensils the surfaces thereof which come in contact with food or drink shall

clean dishes as may be possible.
All single service articles and utensils shall be purchased in sanitary cartons and stored in a clean,
dry place until used, and after removal from the cartons, these articles shall be handled in such a
manner as to prevent contamination.
