Overview

a Steaming appliance with pressureswitch

d Reduction

b Magnetic valve water vaporelimination

e Water supply pipe

c Heat exchanger (up to approx.50°degrees)

Description • The electronics control the DynaSteam steaming appliance. Theyregulate the water quantity for generating steam. DynaSteamguarantees, regardless of the water pressure, the precise supplyof the required quantity of water. The prerequisite for this is acustomer-supplied water flow pressure between 2 and 6 bar. Thewater pressure is monitored using a pressure switch.

• The DynaSteam steaming appliance cannot be calibrated and iscompletely electronically controlled.

• The heat exchange heats the water in advance up to 50°C. Theheat from the exhaust pipe is used for this.

• The water comes through the water supply pipe to the fan impellerin the cooking chamber. The fan impeller creates small waterdrops, which evaporate in the hot oven atmosphere. The waterevaporates in the cooking chamber and on the fan impeller. Thetapering of the hose stabilizes the water flow of the pulsingsteaming unit.

a Magnetic valve K12 c Pump G24b Pump G16

The following purification stages are available on the fully automaticcleaning WaveClean:

• Short: duration of about one hour

• Normal: duration about two hours

• Extra: duration approximately three hoursDescription 1. Testing the cooking chamber temperature.

Automatic cooling of the cooking chamber, if > 55°C.2. Inserting the WaveClean cartridge.3. Water exchange of siphon content by the siphon pump G24 and

solenoid valve K12.4. Circulation of water by means of pump G16. Thus pre-cleaning of

the cooking chamber. Then anew siphon water exchange.The heater heats the oven to 55°C.

5. Start cleaning.Fan motor and WaveClean pump G16 active.Heating active. Heating the cooking chamber to about 70°C.The first layer of wax melts in the WaveClean cartridge. Thecleaner falls into the cooking chamber and mixes with water.The fan motor operates in both directions of rotation and atdifferent speeds.The cleaning phase duration depends on the selectedprogram.

6. A new water exchange of siphon content by means of the siphonpump G24 and solenoid valve K12.

7. Start of rinsing.Identical to step 5 (cleaning).Differences: Heating of the cooking chamber to 92°C. Thesecond layer of wax melts in the WaveClean cartridge. Therinse agent drops into the cooking chamber and mixes withwater.Final rinse to bring the pH value to the normal level.

8. In the programs "normal" and "extra" additional drying of theinterior occurs by means of hot air.

9. Finally, an indicator for withdrawing the WaveClean cartridgeappears, and has to be confirmed.

INFORMATIONDespite different cleaning durations, all cleaning steps require the sameamount of water.During the cleaning process about 3 liters of water are provided by the steam-ing unit into the oven.

WaveClean termination

INFORMATIONWaveClean forced rinsing

The WaveClean forced rinse is automatically started by the operator in case offailure or premature termination. The duration is 12 minutes. An entry is madeinto the HACCP and in the diagnostic memory.

Step 1 (test door contact)1. Open cooking chamber door and close again.

If test successful, proceed with the next test step.If the door is not recognized as having been opened andclosed again within the specified time (60 seconds), the test isnot passed.

Step 2 (prepare for WaveClean)1. Preparation for WaveClean test.

Automatic water exchange via the siphon pump and the solenoidvalve for steam elimination.

Step 3 (heat output)1. Check of heat output.

Display switches to green = test successful.Display switches to red = test not successful.

Check of on-site voltage supply.Check of heating element for electric energy typeCheck of semiconductor relay for electric energy typeCheck of ignition process for gas energy typeCheck of internal fuse for load circuit (depends on unit version).
