Safety and Warranty
A door safety switch interrupts the appliance’s operation during washing, if the door is opened in error. The
pump motor winding has integrated thermal protection which interrupts power supply to the pump, in case
of overload or overheating. A thermal safety fuse interrupts power supply in case of booster or wash tank
overheating. No technical modications are allowed in this appliance. The manufacturer is not responsible for
any resulting damages due to modications. The same applies if the appliance is used for any other purpose,
except the ones indicated.

DRAINAGE CONNECTION
Outow is accomplished by gravity (natural ow) in the CD-GR-1500. The outlet hose should be connected
either directly to a oor drain or drain which must not be higher than the level of the outlet at the rear of the
machine. An open drain connection or one to a vented drain pipe is recommended.
ELECTRICAL CONNECTION
The dishwasher operates under specic voltage as noted on the attached Technical Specications label.
Note: A licensed electrician should be used for the connection according to local codes.
A 208 or 230 volt, one (1) phase, 60hz, 50A power circuit is required as unit draws 43A using 2 wire plus
ground. No neutral (115 volt service) is required. The ground line must be connected at the junction block.
Prepare power line with about 35” ( 95 CM ) of wire with the shielding removed. Install either a ¾” connector or
½” with ½” x ¾” bushings.
Open front control panel by removing two nuts and open inside cover by removing 4 nuts holding cover.
Insert power line in appropriate ¾” hole in rear panel, or if suitable, a ½” connector with bushings can be used,
mount connector, and feed wire to front control box terminals. Mounting posts are provided to hold wires with
“Tye Wraps”. Allow sufcient slack at panel end to allow wire to move when control panel is repositioned to
closed.
Connect power line to junction block. Be sure connections are tight.
Close control panel cover with the 4 nuts, and close the front panel with the two acorn nuts.
After installation, the dishwasher should be cleaned thoroughly before putting into operation.
INSTRUCTIONS FOR REGULAR OPERATION
The appliance is intended to clean dishes, cups, glasses, silver, etc. Be sure the items placed to be washed
are suitable for dishwashing. Silver should be cleaned of heavy food residues, if not washed right after use.
This machine is not intended for use with items which were used with acids, mineral oil, grease, gasoline or
colors.

8
Operation
PREPARATION OF DISHES FOR WASHING.
For best results avoid allowing food residues to dry. Remove bulk food residues, olive pips, lemon peels, tooth
picks, etc., before placing the dishes in the basket.
If washing is delayed, we recommend that you soak dishes and/or glasses which have food residues.
LOADING BASKETS
Place glasses and cups, with the opening facing down and not piled one on top of the other, in
the appropriate baskets. Glasses should not touch each other (damage to glass or stains due
to contact may occur).
Plates should be stacked vertically in appropriate baskets and not touching each other, look
to the side of the baskets to see the recommended loading capacity.
Place tableware in the supplied plastic basket, with handles downwards or placed freely in
a level plastic basket.
In any case, avoid overloading.
AUTOMATIC FILLING OF DETERGENT
This model has an automatic detergent pump for use with a container of non foaming liquid detergent. The
detergent pump is a peristaltic regulated (looks exactly like the rinse-aid pump) and can be regulated by a
screw above and on the right of the glass cover. The regulation can be from 0 lt/hour to 3,0 lt/hr.
both pumps are mounting vertically on an inox bracket in front of the washing pump and are marked with two
yellow stickers.
MANUAL FILLING OF DETERGENT
Use only non-foaming detergent suitable for commercial dishwashers. In the event of non use or malfunction
of the automatic detergent injection system, put the detergent suppliers recommended amount directly into the
wash compartment tank after the machine has reached its operating temperature.
The correct dosage depends on the water hardness and the amount of dirt on the dishes.
Follow the detergent manufacturer’s recommendations. Less detergent deters good washing results and more
detergent usually does not provide better results, but rather more unnecessary consumption and environment
pollution.
Do not use granular detergent. Poor results usually occur.
Do not use caustic products. This will void the guarantee.

9
Operation
RINSE-AID PUMP
Before you perform these adjustments, turn off the power supply.
This model has an automatic rinse-aid pump for use with a container of liquid rinse-aid. The rinse-aid pump is
a peristaltic regulated (looks exactly like the detergent pump) and can be regulated by a screw above and on
the right of the glass cover. The regulation can be from 0 lt/hour to 0,7 lt/hr.
The dozer is adjusted from the manufacturer’s premises at its maximum value for easy initial priming
and must be adjusted accordingly (depending on water hardness, water pressure, how dirty the dishes
are, and the detergent used).
For initial priming of dozer, during the initial lling of the wash tank, start by switching on machine normally.
While the wash tank is lling, during the initialization only, open and close the door in 5 second intervals. Be
careful of spraying water. Do this for about 10 times, and the rinse system will be primed. Empty wash tank and
ll normally. Operate 2 or 3 wash cycles and machine is now ready to be calibrated or ready for normal use.
To reduce (-) the amount of rinse aid, turn the center screw clockwise. To increase (+), turn counterclockwise.
Note: this is a 15 revolution adjusting screw to provide ne adjustments as required.
Hint to installing personnel: After priming system by operating machine through several cycles, rotate
adjusting screw gently to full closed position (clockwise) and adjust (counter-clockwise) about 7 full revolutions.
Empty wash tank and rell with fresh water. Operate for two or three cycles and verify concentration level.
Adjust dozer to achieve nal desired results.
OPERATION
1. Check that the pump inlet lter has been placed in the correct position if it was removed for cleaning.
2. Check that the overow stand pipe is inserted correctly in its outlet.
3. Close door.
4. Turn power switch to “ON” (switches should now illuminate.)
5. The dishwasher will ll automatically.
6. The booster indicator should come on to indicate that the inlet water to the rinse and ll system is being
heated to the required rinse temperature (usually 195°F / 91°C.)
7. When the booster water has reached the correct temperature, the corresponding light switches off and the
wash tank light comes on if the wash water temperature is not sufciently hot (usually 165°F / 74°C.)
8. At initial daily start, allow about 10 to 20 minutes for machine to stabilize water temperatures to their proper
temperatures.
Note: After warm-up, one initial wash cycle should be performed to thoroughly mix soap and water
and be sure unit is fully warmed up and ready to wash properly.
9. After initial warm-up, when all heater lights are off, the dishwasher is ready to wash.
Note: If door is opened during operation, the safety control will turn off the timer. Washing or
rinsing will restart from beginning of wash cycle.
10. Open the door, insert the basket with the items (dishes, glasses, etc.) noting that heavy food residue
has been removed. (If the automatic soap injection system is not used, pour the proper amount of liquid

Maintenance
MAINTENANCE / CARE / REPAIR
Proper operation and safe use may be ensured only through the correct use of the appliance, as well as
the compliance with the operation instructions, the corresponding specications and the care and cleaning
indications.
Notice: Before cleaning or performing any maintenance, other than daily interior cleaning, power and water
supply must be turned off. The appliance should never be sprayed with water or high pressure cleaning
solution, because any water or solution which may get into the electrical components will affect operation of the
appliance as well as present a potential for electrical shock. No safety systems should be disabled.
REGULAR MAINTENANCE AND CLEANING WORKS
Depending on local water hardness, the nozzles on the rinse arms should be cleaned regularly. Caution must
be exercised to not damage the nozzles.
PAY ATTENTION TO THE CORRECT POSITION OF FILTERS AND WASH ARM INSTALLATIONS AND BE
SURE NON-STICK BUSHINGS ARE NOT WORN.
Clean the appliance with warm water and conventional cleaning aids.
Stainless steel parts should never be cleaned them with “steel wool”, wire brush, etc, since even the lightest
contacts on the surfaces with steel may contaminate the stainless steel and cause rust formation. Use brushes
made of polymer plastic, natural bristles, or thin brass wire. Always keep brush movements in line with grain in
the Stainless Steel so that you will not affect the appearance. Finally, rinse with clean water and dry thoroughly.
We remind you that corrosion (rust formation) on stainless steel surfaces is not created by itself, but
rather due to the use of improper cleaning products (e.g. whitening or particularly caustic cleaning
products based on chlorine). Occasionally calcium sediments will form on the internal walls of the
dishwasher (due to mineral particles in the water), which may affect the correct operation of the
appliance and requiring regular removal.
SPARE PARTS, ACCESSORIES AND COMPONENTS
Spare parts and components are usually available at the authorized local service agency, or directly from
Omcan, In case of claims or complaints, you must supply the model and serial number of the appliance /
machine found on the specication label of the appliance.
