DC SERIES WARE WASHING

Gravity waste

• Connect the waste hose directly into the waste outlet. This can be sealed into the pipe.

• A "running trap " or "P trap" must be used to prevent odours returning into the machine.

• The hose can be shortened but enough slack should be left to allow the machine to be pulled out for servicing.

• The waste outlet "running trap " or "P trap" level should be around 100mm below the water level inside the machine

100mm

to allow proper drainage.

• Make sure drain hose is kink-free and not liable to be crushed when the machine is pushed into place.

Pumped waste

• Connect the waste hose directly into the waste stand pipe. This should be approximately 400mm above the water

100mm

level inside the wash tank of the machine.

• Insert the waste hose into the stand pipe using the high loop hook. (supplied).

• Do not seal the waste hose into the stand pipe, this must be plumbed as an "open to air " connection.

• A "running trap " or "P trap" should be used to prevent odours returning into the machine.

• Make sure drain hose is kink-free and not liable to be crushed when the machine is pushed into place.

Electrical connections

• Connect the mains cable supplied with the machine 30amp or three phase-3P+N(3x13A) or above supply as required

by the machine specifications.

• Electrical supply 30amp or three phase supply must be connected by a qualified electrician or catering engineer

trained for this type of machine. There should be a suitably rated mains on/off switch fitted close to the machine.

Pre-test

• Turn on the water supply to the machine and check for any leaks. Turn on the mains power supply and then the

machine on/off switch, the wash tank will start to fill and the boiler will begin to heat. The boiler amber lamp will go

out when the adjusted boiler temperature is reached (see commissioning the machine).

Detergent and Rinse aid dosing pump priming and adjustment

• Remove the lower front panel of the machine to access the peristaltic dosing pump.

• Check the red detergent tube & clear rinse aid tubes do not fowl the cooling fan on the waste pump (if fitted).

• As the wash tank fills with water turn both adjustments to maximum temporarily to prime the machine with chemicals.

• Reduce the detergent adjustment to (4 - 5) test the washing results and increase the adjustment if necessary.

• Reduce the rinse aid adjustment to (2 - 3) test the washing results and increase the adjustment if necessary.

• As a guide only allow 4mm to 6mm of foam to be visible on the wash tank water surface at the end of a wash cycle.

WARNING! Failure to adjust the peristaltic dosing pump correctly will result in poor results or damage to the

machine.

Too much rinse aid can result in foaming and cause cloudiness or streaks on glasses or dishes.

Hard water conditions will adversely affect washing performance and cause spotting on glasses or dishes.

To maximize the performance of the machine it is recommended that a water softener be fitted to improve the

detergent and rinse aid results and eliminate lime scale build up inside the machine.

Chemical products & suppliers may vary in the concentration and quality of there detergent and rinse aid, it is

important that adjustment are made with this taken into consideration. Changing supplier or concentration of

the chemicals used in the future may need new adjustments to be made to the dosing pump.

Commissioning the machine

• Adjust the rinse boiler temperature dial to 86c or as required. The wash tank thermostat will be factory set to 55c.

• Run through several cycles, the machine will wash and then move onto the rinse part of the cycle before finishing.

• Check for waste pump (if fitted) & dosing pump activation at the end of each cycle.

• Check temperatures for the rinse boiler and wash tank. Run several full basket loads through the machine and study

the results at the end of the wash cycle, adjust dosing pumps or temperatures accordingly.
