4. Consider media replacement if after 30 minutes of
settling, a measurable layer of sediment is within or on
top of the filter media or fine, colored particles are
suspended in the water. This condition can mean the
organic loading may be excessive.

Granular filter media for WHIRLPOOL SPAS and SPA POOLS
must be changed based on the inspection and sedimentation test
results or every 12 months, whichever is more frequent. For all
other RWFs, granular filter media must be changed based on the
inspection and sedimentation results or per the manufacturer’s
recommendations, whichever is more frequent.

Results of both the filter inspection and sedimentation test must be
recorded.

6.3.1.2.4 Cartridge Filter Inspection and Filter Change (10)
Cartridge or canister-type filters must be inspected weekly for
WHIRLPOOL SPAS and SPA POOLS. For all other RWFs,
cartridge filters must be inspected every 2 weeks, or in accordance
with the manufacturer’s recommendation, whichever is more
frequent.

The filters must be inspected for cracks, breaks, damaged
components, and excessive organic accumulation. Cartridge or
canister-type filters must be changed based on the inspection
results, or as recommended by the manufacturer, whichever is
more frequent.

At least one replacement cartridge or canister-type filter must be
available.

6.3.1.2.5 Other Filter Media (10)
Inspect and change filters based on the manufacturer’s
recommendations.

6.3.1.2.6 Filter Housing Cleaning and Disinfection (10)
The filter housing must be cleaned, rinsed, and disinfected before
the new filter media is placed in it. DISINFECTION must be
accomplished with an appropriate HALOGEN-based
DISINFECTANT. At a minimum, a 50-ppm solution for 1 minute,
or equivalent CT VALUE, must be used. Records must be
maintained on all inspection and cleaning procedures.

The filter housing must be cleaned, rinsed, and disinfected each
time the filter media—including cartridge filter—is changed.
