Operation; Maintenance; Filter Cartridge Replacement Procedure - OptiPure QT-2+ Installation, Operation & Maintenance Manual

Operation

With adequate pressure, normal operation of the OptiPure System is completely automatic. Dependable operation
involves only monitoring of outlet pressure, periodic filter changes and service documentation.

Maintenance

The only routine maintenance your OptiPure System should ever require is periodic filter cartridge changes or re-
placement sump O-rings. Filter changes are necessary for optimum performance of your foodservice equipment. If
the system sizing recommendations have been followed the OptiPure System is designed to provide a six (6) month
filter replacement interval on most tap water.
Filter Change Frequency
Several situations will mandate filter changes. Complete filter sets should be changed when any of the following ap-
ply:
• 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 prefiltra-
tion or evaluate system sizing recommendations.

Filter Cartridge Replacement Procedure

IMPORTANT: Determine whether all equipment connected to the OptiPure System must be turned off prior to shut-
ting 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 le� 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 two (2)
minutes.
