6. FUNCTIONAL DESCRIPTION6.1 Operating functionThe waste water from the spittoon flows to thecoarse filter (3) and into the storage container(4). When sufficient fluid has collected the floatcontact (2) activates the Reed contact (1)which serves to switch the suction unit on. Thecontrol electronics activate the solenoid elec-trovalve (6), so that the incoming stream ofcompressed air (5) opens the cut-off valve (7).The fluids are fed directly into the vacuum sy-stem.

INSTALLATION

7. NOTESThe Institute for Civil Engineering inBerlin has set a max. waste water flowof 4 l/min per treatment station. For thisreason the water-driven suction hoseshould be cut off during this period.

• Check the setting on the water ring pump:- Any vacuum should not exceed 160

mbar (1.6 kPa), set if necessary.- Reduce the flow of water to the lowest re-

commended by the manufacturer. Waterconsumption c. 2 l/min.

• Do not remove either the gold collector orcoarse filter from the spittoon unit!

Treatment staions into which thespittoon valve unit is to be installedmust be cut off from any currentand protected from accidental swit-ching on!

• The spittoon valve unit (12) may only be in-stalledand operated in treatment stations(chairs) and in dry rooms.Ii this is not possible, then the spittoon valveunit (12) must be fitted in a housing and lo-cated either near the treatment unit or thewall socket.

9.1 Installation Valve UnitWe recommend that the spittoon valveunit (12) be installed inside the treat-ment unit (chair) in the supply to thewaste water connection from the spit-toon (10).

• Mount the spittoon valve unit in a suitable lo-cation in the treatment chair.

• Cut the waste water outlet hose at a suitablepoint and insert the spittoon valve unit. If ne-cessary use parts of the connector series(see Special Accessories under section 3.1).

9.2 Electronics box - alternative set-up

• The box containing the electronics (8) canbe detached from the spittoon valve unit andmounted separately into the treatment unit.The automatic cleaning operation is activa-ted using the electronics box switch.Therefore, the electronics box must bemounted in a visible and accessible locati-on.The distance from the spittoon valve unitshould not exceed 25 cm.

If access is poor or the max. distanceof 25 cm is not possible then theswitch module (11) 7560-520-00should be fitted.

• Place the switch module (11) in a good visi-ble and accessible location near to the spit-toon valve unit (9).

9.3 Compressed air supplyCheck the compressed air supply:if a pressure of 5 bar is exceeded,an additional pressure reducer is ne-cessary (15, 7560-991-00) and shouldbe installed.

• Cut the compressed air hose (14) perpendi-cularly after the pressure reducer (lower airpressure) and fit the T-piece connector (13)with 4mm fork.

• Fit a tecalan hose between the T-piece (13)and the spittoon valve unit.

When inserting or removing the pres-sure hose (14) press the black socketend on the air connection (16) in-wards.

9.4 Installation selector valveIf no station selector valve has beenfitted, we recommend the installationof s selector (21) to be placed bet-ween the outlet from the hose manifoldset (22).
