•Upper level (Moment of switching on as pressure is increased)
•Lower level (Moment of switching off as pressure is decreased)
Adjusting Pressure Switches (If necessary)
1. The pressure switches should be set correctly, however, it is necessary to verify the
correct settings, and make any adjustments if needed.
2. Connect the hand pump to the appropriate channel.
3. Increase pressure using hand pump until the switch activates.
4. Verify pressure level for activation.
5. Slowly decrease pressure on hand pump until the switch deactivates.
6. Verify pressure level for deactivation.
7. If any adjustments are necessary to the pressure switches, adjust the central screw 1 to
set the upper level. Adjust screw 2 to set the difference in upper and lower levels.

Setting channel pump regulators
1. Ensure WLD block is installed in basin
2. Using the expert screen, fill basin with several inches of water by closing the drain, and
turning on water supply.
3. Turn on the channel pump, open the spray head, and open each of the channels one by
one to prime the lines.
4. After lines are primed, close the spray head and all the channels. Remember that the
elevator channel is normally open, and must be activated to close.
5. At this point, the channel pump should be pumping against a deadhead (no flow).
6. Adjust the channel pump regulator for 24 psi (± 1 psi) with the pump deadheaded.
7. Secure the regulator’s adjusting knob by pressing it in.
•Update the software if necessary
•Reattach the alcohol and detergent containers. Prime the alcohol and detergent lines in expert mode
for both sides.
1. For detergent activate P0Z until detergent starts entering the basin, then press “release
all”.
2. For alcohol activate Y10, Y11, and P0C until alcohol starts entering basin through the
elevator port on the hookup block, then press “release all”.
•Run test cycles on both sides and check for fluid leaks
•No waterline disinfection is needed unless work on the water supply valve or the pre-filter has been
performed
•Perform a backup, follow procedure 50096-867
