Maintenance
Regular maintenance is essential to the performance and longevity of the
AQLP system. The maintenance consists of changing the pre filters, changing
the post filter if so equiped, and sanitizing the system. The filters should be
changed every 3 months to 1 year, depending on the quality of the feed water.
The system should be sanitized at least annually. Contact your dealer or the
factory for information in detemining the frequency of maintenance.
Prefilter Replacement
Turn off the feedwater and the storage tank valves. De-pressurize the
system by opening one the point of use faucets until the flow stops.
Locate the sediment filter sump and unscrew the sump by turning it clock-
wise (top view) until it is off. Empty the water from the sump and discard the
filter. Clean the sump with warm water and soap, inspect the o-ring, and put 1/
2 teaspoon of household chlorine bleach into the sump. Set a new sediment
filter into the sump and screw the sump onto the filter head until snug. Be
careful not to overtighten the sump.
Next, locate the pre carbon filters (if so equiped) and unscrew the sumps
clockwise (top view) until they are off. Empty the water from the sumps and
discard the filters. Clean the sumps with warm water and soap, inspect the o-
rings. Put new carbon filters into the sumps and then put 1/2 teaspoon of
household chlorine bleach into the center of each carbon filter. Screw the
sumps onto the filter heads until snug. Be careful not to overtighten the sumps.
