All electrical ratings provided in this manual are for reference
only.Always refer to the machine data plate to get exact electrical
information for this machine. All electrical work performed on
machines should be done in accordance with applicable
local, state, territorial, and national codes. Work should only
be performed by qualied electricians and authorized service
agents.
Note that all electrical wiring used in the CG- series of machines
must be rated, at a minimum, for 212 °F (100 °C), and that only
copper conductors must be used.
Where applicable, heating element amperage draws have been
adjusted for the assumed input voltage. The manufacturer
assumes incoming voltages will be either 208 or 230 Volts. Some
heating elements used in the machines could be rated for other
voltages, so always verify the amperage draw of the machine in
operation when sizing circuit protection.
If the dishmachine is equipped with an optional rinse heater, note
the rinse heater might have its own electrical connection and
require a separate service.Amperage loads for motors and heaters

Before installing the unit, check packaging and machine for damage. Damaged
packaging might be an indication of damage to the machine. If there is any type
of damage to both packaging and unit, do not throw away the packaging. The
dishmachine has been inspected at the factory before shipping and is expected to
arrive in new, undamaged condition. However, rough handling by carriers or others
might result in damage to the unit while in transit. If this occurs, do not return the unit to
the manufacturer. Instead, contact the carrier and ask them to send a representative
to the site to inspect the damage and request that an inspection report be completed.
Contact the carrier within 48 hours of receiving the machine as well as the dealer that
sold you the unit.
The machine should be unpacked and removed from the pallet before installing.
Remove all of the materials from inside. Once unpacked, verify there are no missing
parts. If a part is missing, contact the manufacturer immediately.
The dishmachine is designed to operate while level. This is important to prevent any
damage to the machine during operation and to ensure the best possible results. The
unit comes equipped with adjustable bullet feet which can be turned using a pair of
pliers. Verify the unit is level from front-to-back and side-to-side before making any
electrical or plumbing connections.
All plumbing connections must be made to adhere to local, state, territorial, and
national codes. The installing plumber is responsible for ensuring the incoming
water lines are ushed of debris before connecting to the machine. Note that chips
and materials from cutting processes can become lodged in the solenoid valves
and prevent them from opening or closing. Any valves that are found to be fouled
or defective because of foreign matter left in the water line, and any subsequent
damage, are not the responsibility of the manufacturer.
Cold water supply must be a minimum of 75 °F with a capacity of 180 GPH at 8-12
PSI. Hot water supply must be a minimum of 120 °F (CG-1200)/130 °F (CG-115) with
a capacity of 10 GPH at 20 ± 5 PSI. Incoming hot and cold water service connections
(supplied by customer) must be a 1/2” NPT pipe size minimum. Install the water
supply line to the dishmachine using copper pipe. It is recommended that a water
shut-o󰀨 valve be installed in the water line between the main supply and the machine
to allow access for service.

PRESSURE
REGULATOR
SHOCK ABSORBER
CONNECTING THE
DRAIN LINE
The manufacturer has an optional water pressure regulator to accommodate areas
where water pressure uctuates or is higher than the recommended pressure. Take
care not to confuse static pressure with ow pressure: static pressure is line pressure in
a “no ow” condition (all valves and services are closed); ow pressure is the pressure
in the ll line when the valve is opened during the cycle.
It is suggested that a shock absorber (not supplied) be installed on the incoming water
line. This prevents water hammer (hydraulic shock)—induced by the solenoid valve
as it operates—from causing damage to the equipment.
The CG- glasswashers have a gravity drain (2” NPT connection). All piping from the
machine to the drain must be a minimum 2” NPT and must not be reduced. There
must also be an air-gap between the machine drain line and the oor sink or drain. If
a grease trap is required by code, it should have a ow capacity of 5 GPM.
After installing the incoming ll line and the drain line, slowly turn on the water supply
to the machine. Check for any leaks and repair as required. All leaks must be
repaired before operating the machine.
Take care not to confuse
static pressure with
ow pressure!

Proper preparation of ware will help ensure good results and fewer re-washes. If not
done properly, ware might not come out clean and the e󰀩ciency of the dishmachine
will be reduced. Scraps should always be removed from ware before being loaded
onto the carousel. Pre-rinsing and pre-soaking are good ideas.
Place cups and glasses upside-down on the carousel so they don't hold water during
the cycle. The dishmachine sanitizes as well as cleans. To do this, ware must be
properly prepared before being placed in the machine.
1. Turn the power switch to the “ON” position; the carousel will begin to rotate.
2. Place glasses upside-down on the carousel.
3. When the glasses have completed the cycle, the paddle switch will activate,
turning o󰀨 the water and carousel.
4. Remove clean glasses which are against the paddle switch.
5. The carousel will begin to rotate again.
Strainers can become clogged with soil and debris as the workday progresses.
Operators should regularly inspect strainers to ensure they have not become
clogged. Clogged strainers reduce the washing capability of the machine and should
be cleaned at regular intervals or as required by workload. See the next section.

OPERATING INSTRUCTIONS
OPERATION
Detergent usage and water hardness are two factors that contribute greatly to how
e󰀩ciently this dishmachine will operate. Using detergent in the proper amount can
become a source of substantial savings. A qualied water treatment specialist can
determine what is needed for maximum e󰀩ciency from the detergent.
1. Hard water greatly a󰀨ects the performance of the dishmachine, causing the
amount of detergent required for washing to increase. If the machine is installed
in an area with hard water, water treatment equipment should be installed.
2. Deposited solids from hard water can cause spotting that will not be removed
with a drying agent. Treated water will reduce this occurence.
3. Treated water might not be suitable for use in other areas of operation and it
might be necessary to install a water treatment unit for the water going to the
dishmachine only. Discuss this option with a qualied water treatment specialist.
4. Dishmachine operators should be properly trained on how much detergent is to
be used per cycle. Meet with a water treatment specialist and detergent vendor
to discuss a complete training program for operators.
5. This dishmachine requires that chemicals be provided for proper operation and
sanitization. Contact a chemical supplier with any questions.
6. Water temperature is an important factor in ensuring that the dishmachine
functions properly, and the machine's data plate details what the minimum
temperatures must be. If minimum requirements are not met, there is a possibility
that dishes will not be clean or sanitized.
7. Instruct dishmachine operators to observe the required temperatures and to
report when they fall below the minimum allowed. A loss of temperature can
indicate a larger problem.
In order to maintain the dishmachine at its optimum performance level, lime and
corrosion deposits must be removed. The frequency for deliming will be based on
water conditions. A deliming solution is available from your chemical supplier. Read
and follow all instructions on the label.
1. Disconnect the detergent pump.
2. Drain and refill the wash tank.
3. Add deliming solution per supplier's instructions.
4. Run machine the period of time recommended by chemical supplier.
5. Wait ve minutes, then inspect the inside of the machine. If the machine is not
delimed, run again.
6. Run two cycles to remove residual deliming solution.
