set temperatures are 160°F (71°C) the wash cycle (tank) and 185°F (85°C) for the rinse cycle (boiler).
RINSE AID DISPENSER OPERATION
OPERATION
It utilizes the di󰀨erence in combined pressure caused by turning the washing pump on and o󰀨, and the rinse
pressure.
WATER CONNECTION
1. Connect the dispenser tube tting A to the pump, by means of the rubber tube installed in the appliance
(pump pressure).
2. Connect the small black rubber tube by the brass delivery tting B to the connection near the boiler
(injector).
3. Make sure that the green product suction tube is inserted on the special tting C and that the small lter
and the ballast are inserted in the rinse aid tank.

adjustment screw D during the wash cycle and open and close the door combined with pressing the pin D. This
method speeds up the rell process.

11
Installation and Operation
ADJUSTMENT
With each rinse cycle, the dispenser draws an amount of rinse aid, adjustable from 0 to 2 cubic inches (from
0 to 4 cc), equivalent to a length of 0 to 11” (from 0 to 30 cm) drawn into the suction tube. In order to regulate
the dispenser to the minimum amount, turn the adjustment screw D (completely clockwise. For the maximum
amount, turn the screw anticlockwise about 20 complete turns.
N.B.: for each turn of the screw the amount of the product drawn into the tube varies by 5/8 inches
(1,6cm), equivalent to 13/16 cubic inches/run (0,2 cm³/turn) - (about 1/8 Dramme/run - 0,21g/turn - with a
concentration of 0,60 oz/cubic inches - 1,05 g/cm³ of rinse aid). The rinse aid cannot function properly
if the di󰀨erence in level between the bottom of the machine and the container exceeds 31 inches (80
cm).
THE DISPENSERS ARE PRE-SET TO A 2” (5 CM) INTAKE OF PRODUCT FOLLOWING A TEST PHASE
SYSTEM CHECK. THIS MEASUREMENT SHOULD BE ADJUSTED ACCORDING TO THE TYPE OF RINSE
AID USED AND WATER HARDNESS.

• The appliance is now ready for a new wash.
• At the end of the day, clean the machine.
• Turn o󰀨 the machine and the water tap.
DISHES AND CUTLERY LOADING
Before loading the dishes it is necessary to carry out a proper cleaning o󰀨 of the food residuals. It is not
necessary to rinse the dishes with water before the loading.
WARNING: do not wash items contaminated by petrol, paint, pieces of steel or iron, ash, sand, wax,
lubricating grease. These substances damage the machine. Do not wash fragile items or made of
material that do not stand the washing process.
FOLLOW THESE TIPS:
• Crockery and cutlery must not lie inside one another, covering each other.
• Place the dishes so that all the surfaces can be reached by the water; otherwise the dishes cannot be
washed properly.
• Make sure that the dishes are placed in a stable position and that the empty containers (cups, glasses,
bowls, etc.) do not turn upside down.
• Place all the empty containers like cups, glasses, etc., upside down.
• Place in tilted position the dishes with deep hollows, so that the water can drain.
• Make sure that the smaller dishes do not fall from the baskets.
• Check all the wash arms runs freely and they are not blocked by too tall or too prominent crockery.
Eventually, run a manual rotation of the arms to check it.
Some foods, such as carrots, tomatoes, and others, may contain some natural dyes substances, that in large
amounts, can alter the crockery and plastic parts colors. Any discoloration does not mean that the plastic is not
heat resistant.
CROCKERY AND CUTLERY NOT SUITABLE FOR DISHWASHER
• Wooden crockery and cutlery or with wooden parts; water at high temperature causes deformation to wood.
Also the adhesives used are not suitable for treatment in the dishwasher; a consequence could be the
handles detachment.
• Crafts, precious vases or decorated glasses.
• Not heat-resistant plastic crockery.

13
Installation and Operation
• Copper, brass, pewter or aluminum objects: they may become discolored or opaque.
• The decorations on glass, after a certain number of washes, can lose gloss.
• Fragile glasses or crystal items, if often washed, can become opaque. We recommend to buy exclusively
crockery and cutlery suitable for dish washing. After several washes, the glass can become opaque.
It is mandatory to repeat the washing cycle if at the end of the cycle the crockery are not well clean or
if there are washing residues (glasses, cups, bowls, etc. with liquid inside).
WARNINGS:
• Do not slam the door when opening and closing.
• Do not put material or objects on the machine.
• The water used for the washing and the rinsing is not potable because of the presence of chemical
additives. In case of contact with skin or eyes wash them immediately with plenty of water and check the
safety instructions of the detergent manufacturer. If necessary, contact a doctor.
• Some important rules must be followed for the use of this appliance:
- Never touch the appliance with wet hands or feet.
- Never use the appliance when barefooted.
- Do not install the appliance in places exposed to water splashes.
• This machine must be disconnected from the main electrical supply after use at the end of the day and for
any service/maintenance operation. Switch o󰀨 the main switch located on the wall, which shall be installed

WASH TANK AND/OR AT THE END OF THE WASH CYCLE.
DETERGENT USE
ONLY use NON FOAMING types suitable for industrial glass-washers and dishwashers. It is advisable to use
liquid detergents. The detergent must be put directly in the tub. The correct amount will be suggested by the
product manufacturer according to the water hardness. By request, the dishwasher can be equipped with an
automatic detergent dosing pump (always recommended). 3/8 inches (1 cm) of the product drawn into the tube
is equal to about 3/32 Dr (0,15g). A correct amount of detergent is very important for a successful wash. This
machine must be operated with an automatic detergent dosing pump. Verify the correct operation by checking
the detergent ow in the transparent suction hose from the detergent canister. Make the check during tank
lling or rinse phase.
RINSE AID USE
The machine is equipped with a rinse aid dispenser. The machine automatically draws the product. The rinse-
aid chemical, shall be suitable for professional glass and dishwashers. It is advisable to rely on specialized
retailers in the sector. The amount dispensed can be regulated by operating the ne-adjustment screw on
the dispenser. Reduce the amount by turning the screw clockwise, increase by turning it anticlockwise. The

Washing results are unsatisfactory. The washing nozzles are obstructed or the rack does not rotate.
Unscrew and clean the nozzles and the rotation shaft carefully, ret
them correctly in their seats.
Filters are dirty. Remove lters, clean with brush under a jet of water
and replace in original position.
Presence of foam. Always use a non-foaming detergent. Have the
detergent and rinse aid dosages checked.
Fats or starches are not removed. Detergent concentration too low.
Check the tank temperature (it must be about 160°F - 71°C). Adjust the
thermostat or check correct heating element operation.
Length of washing cycle inadequate for type of grime build-up. Choose
a longer cycle if possible, otherwise repeat wash cycle.
Wash water too dirty. Empty water from the tank, clean lters; rell the
tank and correctly ret the lters.
The objects are not dried properly. Wrong rinse aid concentration. Have the rinse aid dosage checked.
The rack is unsuitable for the glasses and dishes. Use a suitable rack
enabling the dishes to be tilted so water can run o󰀨.
The dishes have been too long in the tank. As soon as the wash cycle is
nished, pull the rack out immediately, allowing the air to dry the glasses
and dishes more quickly.
Rinse water temperature is less than 185°F (85°C). Check the
temperature of the booster thermostat. Call Omcan service to adjust.
Surface of dishes and glasses too rough or porous for material wear.
Replace type of dishes and glasses used.
Streaks and spots on glasses and
dishes.
