MAINTENANCE
The Bio-Logic
®
Pure Water Pack
TM
is designed to operate with a minimal amount of maintenance, providing the water
quality does not exceed maximum concentration levels, see “Water Quality” in the “Product Application” section. Ordinary
maintenance consists of;
• Filter cartridge replacement is recommended every 12 months. Over time water pressure to the system faucet will drop,
this is an indication that the filter cartridges are nearing the end of their service life.
• In poor quality water supplies filter cartridges may clog more rapidly, before the 12 months are up, reducing water
pressure to the system faucet. In these cases, change filter cartridges immediately. Changing filter cartridges will restore
normal water pressure.
• Lamp replacement is recommended every 10,000 hours of operation (approximately 12 months of continuous service).
• Cleaning of the quartz sleeve, when conditions warrant.
• Always disconnect the water supply and completely drain the water purifier if it will be subjected to temperatures
below freezing.
• Contact factory with questions.
INSPECTION
1. Regularly inspect the water purifier to ensure that the germicidal lamp is still in operation.
• An LED indicator light, located on the ballast, provides visual indication of germicidal lamp operation. This provides an
indication of lamp operation and does not indicate the level of ultraviolet intensity or transmission through the water.
2. To ensure proper operation of the Bio-Logic
®
Pure Water Pack
TM
, regular biological testing should be performed on a
schedule recommended by local public health authorities, or at minimum; at installation, quarterly for the first year of service
and annually, at lamp replacement, for the life of the water purifier.
3. Additional testing should be performed whenever modifications, change or additions are made to plumbing system, pumps,
well source water etc. to ensure adequate disinfection under new condition.
4. As with any water purifier installation, routine maintenance is necessary to ensure your equipment is operating correctly.
Regular inspection must also include the inspection of the ground to ensure grounding wires are secure to both the water
purifier and grounding point as originally installed. Regular inspection must also include confirmation that approved ground
fault circuit interrupt (GFCI) receptacle is still operational and that water purifier is plugged into this GFCI. Any components
which are damaged, or broken should be replaced.
FILTER CARTRIDGE REPLACEMENT
SAFETY EQUIPMENT REQUIRED TO PERFORM TASK
CAUTION: Never remove filter housings while the system is pressurized.
NOTE: Place a small bucket under the system, when changing filter cartridges, to catch any water that may leak from system.
1. WARNING: Disconnect and remove power to water purifier.
2. Shut off water supply to the system, by closing the supply valve. Open the system faucet and allow the system to drain.
3. Release the pressure in the filter housing, by pressing the red pressure release button, located on top of each filter housing.

4. Using the filter-housing wrench, loosen the filter housing by turning the housing clockwise. Remove the filter housing. Be
careful, the filter housing will be full with water, adding to the weight of the filter housing. Be sure not to lose the large
O-ring seal.
5. Drain water from filter housing, remove and discard old filter cartridge.
6. Clean the inside of the filter housing before installing the new filter cartridge. Wash the inside of the filter housing with soap
and hot water, rinse out thoroughly. Make sure the O-ring is fully seated, in its groove.
7. Remove the wrapper from the new filter cartridge, and place into the filter housing. The filter cartridge will fit into the
filter housing in either direction. The system uses 2 different filter cartridges. Be sure to install the correct cartridge into its
corresponding filter housing.
8. Replace filter housing and cartridge onto filter head and firmly tighten, by turning filter housing counter-clockwise. Be
careful not to cross thread the housing and filter head. (Continued on Page 11)
