Module

Solenoid valve MV11 is caught.

Defective membrane in the module of the instrument for which the error does not occur.

MV21-X on module defective (X – holder no.)

White break on “auto” valve of module due to excessive screwing torque or spring force too low.

Filter tissue of heater is dissolved.

Precipitation in the heater element.

Replace MV11.

Replace module.

Replace solenoid valve MV11.

Replace membrane and check input pressure. Pressure = 4.3 bar +/- 0.1

(in case SPRAYVIT flow is active).

Replace MV21.X.

replace “auto” valve, do not tighten too hard. Check filter in heater.

Check filter in heater and replace it, if necessary, and rinse water pipes.

(Defective filter and information to Bensheim)

Replace heater and rinse water pipes.

1.Adjusting cuspidor flushing:

For right-handed version – Remove side panel A of water unit and adjust control nozzle B until the bottom of the cuspidor is flushed evenly. Remount back side panel A of water unit.

For left-handed version – Remove cover C. Lift rubber cover and adjust control nozzle B using a coin until the bottom of the cuspidor is flushed evenly. Refit the cover.

2.Check the swivel-back motion of the cuspidor:

–Swivel the cuspidor into the movement range of the chair

–Press the manual chair button and start the chair program consecutively

The cuspidor must always swivel back into the starting position automatically
