Filter Change Frequency
Several situations will mandate filter changes. Complete filter
sets should be changed when any of the following apply:
• Six (6) Months have passed since unit installation or previous
filter change.
• Reduced water flow.
If filter change frequency is less than 6 months due to pressure
drop, it may be necessary to add additional prefiltration or evalu-
ate system sizing recommendations.
Filter Cartridge Replacement Procedure
IMPORTANT: Determine whether all equipment connected to
the OptiPure System must be turned off prior to shutting off water
supply from filters.
1. Close inlet ball valve.
2. Relieve pressure downline by opening flush valve or briefly
actuating equipment.
3. Turn cartridge to the left 1/4 turn until it stops.
4. Pull down on the cartridge until it clears head. Discard old
cartridge.
5. Line up the upward-arrow on the new cartridge with the
upward pointing arrow on the head.
6. Push cartridge up into head until it stops and turn to right
until it stops. (The upward-arrow on the cartridge should
align with the downward-arrow on the head).
7. Open the inlet ball valve.
8. Open down-stream flush valve to flush new cartridge at the
specified flow rate for a minimum of ten (10) minutes.

Pressure Gauge Monitoring
Periodically monitor the pressure gauge on the OptiPure unit.
If the needle on the gauge ever enters the red zone (while the
connected equipment is in operation and water is flowing through
the system to the equipment) it may be an indication that the
filters have become clogged with sediment. Ideally the pressure
should never drop into the red zone.
Maintenance
The only routine maintenance your OptiPure System should ever
require is periodic filter cartridge changes or replacement sump
O-rings. Filter changes are necessary for optimum performance
of your foodservice equipment. If the system sizing recommen-
dations have been followed the OptiPure System is designed to
provide a six (6) month filter replacement interval on most tap
water.
