DPS1 DPS2 RPS1 RPS2

- An interface for the dosing equipment is provided in the control box of the dish washer using terminals which have assigned defined functions. Terminal specification: DPS1 "Fire" (wash pump ON) Signal for dosing detergent DPS2 "Neutral" Signal for dosing detergent RPS1 "Fire" (fill valve open) Signal for dosing rinse aid RPS2 "Neutral" (wash pump ON) Signal for dosing rinse aid - Connect the wiring to the terminal in the control box.

9

C800 DISHWASHER OPERATION INSTRUCTIONS - Recommended dosing concentration Concentration of detergent and rinse aid depends on soil concentration (pre scrapping), water conditions and wash ware type. Typical recommended concentration levels are as follows: Detergent: 2 – 4 g/l Rinse aid: 0.2 – 0.5 g/l

(of tank regeneration) (of rinse water consumption)

3.1.5 CONNECTION DYING MODULE -

Install dying control box by the four bolt under the dying Fixed Harness by ties lying the back and top of dying Remove the front panel of electric heating box Ground connection

- Plug the fan wiring harness 1M8

- Connect respectively drying and heater wiring harness 1B9-11/21/31

- Connect the temperature sensor harness 1B5-1/-2

- Reinstall the front panel of the drying and electrically heater box - This wire harness connects to the main control box

10

- Sequentially check the wires that if they connect correctly and if do than fix with cable ties; the wires should be neatly arranged NOTE: Do not job when you stand the top of wash room: Check all bolts and connections, verify that tightened.

3.2 WATER CONNECTION Must be carried out by an authorized technician according to the national and local codes. The machine must be operated with potable water. For water with an extremely high mineral content an external demineralization is strongly recommended.

3.2.1 GENERAL - Connect water supply and drain pipes according to installation plan. - Class A air gap is fitted to the machine as standard.

3.2.2 WATER SUPPLY CONNECTION (G3/4") -

Should be soft (up to 4° Clark, resp. 0.5 mmol/l,10 - 82°C). Must be cold if condenser is fitted. Line flow pressure 1.5 - 6 bar, at least 350 l/hr. Provide shut-off valve at site.

NOTE:The water hardness should be ≤0.5mmol/L. If not, water softener is strongly recommended. Or else, may affect the warranty set out in the standard conditions of sale.

3.2.3 DRAIN CONNECTION -

To be connected to site drain: Tank drain DN50. Drip water drains off tabling, sink and other elements. All drains must be connected to goose neck (individually or single point).

11

C800 DISHWASHER OPERATION INSTRUCTIONS 3.3 STEAM CONNECTION(OPTION) Must be carried out by a qualified technician according to the national and local codes. NOTE FOR INSTALLATION Make sure that pressure and temperature of the heating medium do not exceed values indicated on the installation plan.

- Install the bracket in the operate table or fix it on the floor on site.

3.3.3 ADJUSTMENT OF SHUT-OFF VALVE - with flow reducer for steam and hot water supply - The built-in shut-off valve is equipped with an adjustment device to limit the heating supply medium. A special tool is necessary for adjusting the valve-seat. - The correct adjustment is very important particularly for higher pressure, and therefore must be done by a HOBART trained service technician before first run. - The optimum adjustment is achieved, when the nominal temperature of the boiler can be held during continuous operation, while the valve is opened to maximum. - If adjusted too far open pressure shocks may occur when the

12

solenoid valve closes. This could cause damage at the installation. - If adjusted too far closed the required heating-power cannot be achieved.

Note: Prepare personal protection before operation, respirator, lag, antiskid shose etg.

23

C800 DISHWASHER OPERATION INSTRUCTIONS 7.2 RACKING(Remove coarse food soil before washing )

when loading plates consider the machine direction

Gastronorm pans and other large containers or boards should ideally be washed in a separate Utensil Washer. In Automatic Rack Type Dishwashers these items may cause problems such as splash-over leading to low water levels in the tank/s and poor rinsing. On the occasions when these items are to be washed, they should be loaded sloping towards the direction of machine operation as shown in the picture. This will reduce the problems described above.

24

7.3 WASHING - By pushing the Conveyor ON button ③ the machine is ready for operation. Conveyor and wash will start. This should be done after the set water level have been reached. Give dishes enough time to dry after washing.

7.4 STAND-BY OPERATION - When no further racks enter the machine, conveyor and wash can be switched off manually by pushing the Conveyor OFF button ④ . The heaters run continuously. - By pushing the Conveyor ON button ③ conveyor and wash will start again.

7.5 MACHINE-OFF In case of operating error or faults, it is possible to switch-off the machine immediately without draining the tanks. - Turn the program selector switch ① to "0" position.

7.6 LOWER WASH PIPE PRESSURE - Reduce the pressure of lower wash arm when clean light or small dishware. - Open the door, take out the lower wash arm, and turn the knob deasil. - Install the lower wash-pipe, and close the door. Then it works under the less pressure. - It can turn back the normal pressure when turn the knob widdershins. - The cleaning result will be affected during in lower pressure state. Strongly recommended: Separate the light and small dishware from normal.

25

C800 DISHWASHER OPERATION INSTRUCTIONS 7.7 CAUTION - Potential crushing hazard.

- Scalding and slipping hazzard. Heat insulating gloves and clothes and non-slip shoes are required.
