SECTION VI
MAINTENANCE SCHEDULE
Maintenance frequency of the vending machine depends on the use of the machine and the feed water quality.
The best way to determine when filters and other components should be changed is to keep a log of tests done
and the date and gallon reading at which they are done. For additional information on maintenance of the
components, please refer to the appropriate sections in this manual.
WARNING: REPLACE COMPONENTS ONLY WITH ORIGINAL FACTORY
REPLACEMENTS. COMPONENTS OF DIFFERENT BRANDS MAY NOT
WORK PROPERLY WITH OTHER PARTS IN THE MACHINE and MAY
CAUSE DAMAGE TO THEM and TO THE HEALTH OF YOUR
CUSTOMERS.
1. Strainer
Test: Monitor pressure drop at sediment filter. Clean or replace after 2 PSI (0.31 bars) drop.
Replace/Clean Establish frequency from test, clean at least once a month.
Frequency:
Failure Mode: Clogged and caused a pressure drop large enough to shut off the reverse osmosis (R.O.) pump,
reducing yield of the R.O. membrane to a trickle.
2. Sediment Filter
Test: Visual, change when dirt penetrates more than 2/3 of the filter or when pressure differential is
10 PSI (0.68 bars) or more, whichever is first. CHECK WEEKLY.
Replace/Clean Establish frequency from test, clean at least once a month.
Frequency:
Failure Mode: Clogged and caused a pressure drop large enough to shut off the R.O. pump, reducing yield of
the R.O. membrane to a trickle.
3. Carbon Filter
Test: Use free chlorine test kit. Free chlorine level should be less than 0.1 ppm. Test at 5 gallons
(18.92 liters), 10,000 gallons (37854.12 liters), 18,000 gallons (68137.41 liters), and after every
replacement. Gallon reading is taken from the water meter. Collect water sample from valve
located between inlet test cell and the water meter.
Replace/Clean Replace any traces of free chlorine (0.1 ppm or higher) but no less frequently than once every
20,000 gallons (75708.24 liters) or every three (3) months, whichever comes first.
