5. Unplug 1/2” outside diameter (O.D.) tubing at the outlet of the Reverse Osmosis (R.O.) pump and plug into
the OUTLET of the 20-inch (50.8 cm) filter housing. (Refer to Tubing and Fitting Replacement Technique
on page 39) for instructions on tubing removal and assembly. Plug the 1/2” O.D. tubing at the INLET of
the 20-inch (50.8 cm) filter housing into the outlet of the pump.
6. Detach the 3/8” O.D. tubing entering the water storage tank (product tubing). Attach the extended length
3/8” O.D. tubing supplied in the kit to the cluster and direct the other end of this tubing into the drain bay.
7. Vend enough water from either bay to cause the R.O. pump to operate. The machine will not begin to
produce water until level is at least 10 gallons (37.85 liters) below full.
8. Open the main water valve and watch the R.O. pump. The pump will start in 30-seconds. Wait 30 to 40-
seconds and shut off the main water valve.
9. Unplug the vending machine and put up a sign for "cleaning, DO NOT use." Let the membrane soak in the
solution for 8 to 16 hours.
10. Open PVC sampling valve after the carbon filter for a few seconds and close it. Remove the 20-inch (50.8
cm) housing and reattach the original 1/2” tubing to the outlet of the R.O. pump. Clean and save the 20-inch
(50.8 cm) housing for the next cleaning and discard the cartridge.
11. Plug vending machine back in and open main water valve. The machine will go through its purge cycle
automatically. Wait until the R.O. pump has run for AT LEAST TEN MINUTES before removing cap
and loosening the locknut on the back pressure valve. With the pump running, adjust the pressure valve until
the pressure on the pump gauge reads 160 PSI (11.03 bars). Tighten the locknut and replace the cap on the
valve.
