Step 5: Cylindrical Air Valve assembly for A drain and O drain units
1. Install hemmed end (not sharp end) of support tube with gasket onto bowl.
2. Place sprayhead with 3/8" tubing onto support tube as shown in Figure 7 on page 10. Run tubing
down through support tube. Make sure spray holes point away from the wall.
3. Place upper tie bar (notched at corners of both ends) on top of sprayhead parallel to wall.
Connect the two threaded tie rods together using the coupling nut with hex head set screws. Run
the tie rod down through upper tie bar (see Figure 7) and secure from underneath the bowl using
the lower tie bar (no notches) and hex nut with socket head set screw. A minimum of 1-1/2" of
threaded tie rod should protrude below the lower tie bar, this will be required to attach the valving.
4. Place actuator module assembly on top of sprayhead. Rotate until actuator locks in with tie bar.
Drop the 1/8" diameter supply tube down to pedestal.
NOTE: Skip to Step 5 for units without soap.
• For units with soap option, install the spacer, soap dispenser and cover using the coupling nut,
third tie rod (8-5/8" long) and second coupling nut as shown (see Figure 8 on page 11).
5. Secure actuator module cover and top cover with acorn nut and socket head set screw.
6. Holding the valve assembly outside of the pedestal, connect 3/8" supply tubing and the 1/8" air tub-
ing from the sprayhead to valve assembly tube connectors (see Figure 9 on page 12).
7. Thread one supplied 3/8" nut onto the tie rod. Slide valve assembly on next and secure with
another 3/8" nut.
FOR “A” UNIT: Connect flexible hoses to supply stops using suitable fittings.
FOR “O” UNIT: Install 1/2" nom. copper tubing supply lines (pass through holes in cover,
down through support column) and connect flexible hoses to supply stop valves using suitable
fittings.
8. Turn supplies on. Open check/stop valves completely.
9. Open volume control valve completely and check piping installation for leaks.
10. Push operating pushbutton until air is purged from the lines.
