Connecting the power supply (this operation must be performed by a qualified fi tter)

Warning

1. The connection to the power supply and earth must comply with local electrical safety regulations.
2. Before connecting the machine, check that the voltage and fuses match the model plate on the machine.
3. Turn off the supply at the mains (400V circuit fuse box) and place a card, clearly visible, near the fuse box, stating that you are carrying out electrical work.

Connect the colour-coded wires correctly (400V) to the mains according to the description and electrical diagram on the inside of the machine panel.

(Electrical diagram: see page 43)

Selecting the cable (400V)

Select the correct cables and contact-breaker switch for the power supply you are using.

Refer to the main technical specifications table to select the appropriate materials for connection.

Connecting the water supply

Warning

1. The water connections must comply with local safety standards and regulations.
2. The minimum water pressure required is 2 kg/cm ^2 . Cleaning performance will be adversely affected if water pressure is too low.
   The temperature of incoming water must not exceed 65^ C, and water pressure must not exceed 5 kg/cm^2 .

Connect the inlet hose to the mains water supply (3/4" internal screw thread). Ensure that your hands are completely clean before you connect the tap or magnetic valve to the mains water supply. The manufacturers will not accept any responsibility for any damage or loss incurred as a result of foreign objects (e.g. dirt, iron or calcium) entering the tap or the magnetic valve. Pull carefully on the inlet pipe to ensure that it is firmly attached. Open the tap slowly and check that no water is leaking. It is necessary to first check that the inlet pipe is firmly attached and the supply line is open each time the dishwasher is used.

Water inlet (Requirements for water inlet)

	Temperature Pressure (dynamic)
	°C °F K Pa kg/cm			2
With 3 KW (230 V) electric boiler 40 ~ 60	04 ~ 140 196 ~	490 2 ~ 5
With 6 KW (400 V) electric boiler 10 ~ 60	50 ~ 140 196 ~	490 2 ~ 5

Water discharge

Connect the water discharge hose to a suitable drainage point. This must be lower that the discharge outlet of the machine to ensure natural drainage. If necessary, to achieve this, the machine can be raised or placed on the stainless steel support frame (optional), or the fi tter can install a drain pump (optional).

If local regulations require a grease trap, it must be installed by a certifi ed company.

Note: After installation, test the pressure of the incoming water supply. If the hydrodynamic pressure is lower than 2 kg/cm^2 , it will be necessary to install a pressure raising pump (from an independent supplier). If the stagnation pressure is higher than 5 kg/cm^2 , it will be necessary to install a pressure reduction valve (from an independent supplier)

Tests

Water inlet hose

Clean the water inlet hose before connecting it. Clean all fi Iters after their first use.

Water connection and hydrodynamic pressure

Check that the inlet hose is firmly connected. The hose may come loose and start leaking if the dishwasher is moved. If the hydrodynamic pressure is too low, this may lead to malfunction of the machine.

Electrical connection

Connect up all the wires in the switch box (400V). Check that all wires are firmly connected. Check that the other electrical components, for example the switches and cable, appear to be in good order.

Inspect the inside of the dishwasher

Check that there is nothing inside the machine that does not belong there (for example: clothes, screws, nuts & bolts, tools, packaging materials, etc.).

11. Washing dishes and cleaning

Washing dishes

• First remove any left-over food from the plates and clean them with a pre-rinse spray.
• Select the required wash cycle, 90 sec., 120 sec. or 180 sec. (standard 120 sec.) depending on the size of the plates and how dirty they are.
• Place the plates in a plate rack. The plates should not touch each other. The water must be able to access both sides of a plate properly. Always place plates on their side in a rack with plate supports.

Cups, glasses and bowls must be placed upside down in an open basket or better still in a compartmentalised basket (img. 3). Cutlery and other small items can be spread loose on the bottom of a finely meshed cutlery basket or in special cutlery baskets.

• Fill the rack, open the door, slide the rack into the CaterChef machine and close the door again. The wash and rinse cycle will begin when the Start button is pressed, the after rinse cycle begins automatically when the wash cycle ends, after which the total cycle is finished (signal).
• Open the door when the wash and rinse cycles are finished and remove the rack of clean items. Slide the next rack of dirty dishes into the machine, close the door and press the Start button.
• If you need to add dishes after the wash cycle has started: turn off the power (0) or open the door 1 cm and wait for 10 seconds before opening the door completely. Allow the spray arms to stop by themselves to avoid being spattered by hot water. Then press Start.

Cleaning

We recommend that the machine is cleaned at least once a day or more often if it is used intensively. It must be cleaned according to the following steps:

1. Disconnect the power and water supply.
2. Open the door and remove the basket and any large food remains left floating.
3. Drain the wash reservoir by disconnecting the overflow pipe.
4. Remove and empty the strainer basket, fi Iter inset and inlet strainer pump and clean them thoroughly.
5. Clean the inside of the machine thoroughly.
6. Replace the strainer basket, filter inset and inlet strainer pump precisely and correctly.
7. Leave the door open to allow the inside to dry naturally (end of clean).
8. Check that the wash and rinse arms can spin freely and are not obstructed.
9. Check that the spray jets are not blocked by limescale or other residue.
10. The power and water supplies must be switched back on before the machine is used again.

12. Maintenance

Warning!

Always disconnect power before any cleaning or maintenance operation!

Wash and rinse arms

The upper and lower wash and rinse arms must be able to spin freely and must continue to spin for several turns after they have been set off by hand. The power must be turned off while the arms are being checked. Spin the arms and remove any obstructive objects.

If the strainer basket, fi lter inset and inlet strainer pump are not placed correctly, the spray arms and jets may be obstructed by such items as food remains or bones.

The spray arms can be removed easily for cleaning.

To remove the wash and rinse arms, the serrated nuts must be unscrewed, after which the wash and rinse arms can be removed (img. 4).

Rinse arm Serrated nut Wash arm

Img.4

Comment:

It is necessary to have a firm grip on the upper wash and rinse arms before totally unscrewing the serrated nut that holds them in place. Be careful not to let them drop.

The upper and lower wash and rinse arms are interchangeable.

Maintaining the heating elements

Due to the high electrical load and lime-rich water found in many areas, it is common for limescale to form on the heating elements. This has a detrimental effect on heat conduction. This is why it is necessary to maintain and clean the dishwasher regularly and to use a water softener!

Remove any limescale residue on the bottom of the reservoir. If in doubt, contact your dealer.

Maintaining the water pipes

Impurities in the water inlet hose (strainer) must be removed regularly to ensure a constant flow of water.

Service

If repairs or other adjustments are necessary, please contact your dealer or service company.

13. Detecting malfunctions

This section could help prevent the need to call out a repair service. If a problem persists after all possible causes have been checked, contact your dealer or a qualified service company.

Problem Possible causes & proposed solution
The machine will not work	First check that the power and water supplies are switched on and working correctly!Open the door and close it again, then press the Start button, and if it doesn't work:1. There may be a blown fuse or activated circuit breaker in the meter cupboard.2. Check if the internal fuse has blown. Switch off the power!3. Check that the rinse arms can spin, remove dirt etc. regularly.
Long wash cycle	1. The temperature in the boiler and/or reservoir is too low. (See the display)2. Check the fi Iter gauze in the water inlet pipe, and clean if necessary.3. If there is too much limescale residue (consult dealer), use a water softener!
Plates are not clean	1. Remove left-over food thoroughly before washing up, use a pre-rinse spray2. The water pressure may be too low due to a blockage in the inlet strainer pump in the reservoir. Disconnect the power supply, empty the reservoir, inspect it and clean the strainer, etc, remove any food remains.3. The water temperatures may be too low. Not enough warming up time after it has been turned on: Check the temperatures in the display panel.4. Incorrect dose of detergent. Contact your detergent supplier or your dealer.5. Descaling may be necessary, use a water softener!6. The plate racks may not be loaded correctly.
Spots and stains on cutlery, glasses and plates	1. The baskets are not loaded correctly.2. Incorrect rinse water temperature (See display).3. Low water pressure caused by an obstructed pump (clean regularly).4. Extremely hard water use a water softener!5. Incorrect detergent for the type of water. (detergent supplier)6. Incorrect rinsing agent for the type of water. (detergent supplier)7. Incorrect concentration of detergent and rinsing agent. (detergent supplier)
