1.2. GL-X Operational Cycle

The GL-X 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.

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.

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

the Machine

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 tan k temperature b etween
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
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.
