Cartridge Cleaning Instructions
Hurricane
®
cartridges are made of Polyester Plus
™
,
a proprietary blend of polyester fibers which can be
cleaned in most applications and micron ratings to
make Hurricane
®
filter elements reusable! For best
results, follow the directions described below:
When Cartridge Cleaning is Possible
Clean cartridge when pressure differential is 12 psi
above startup differential.
Non-cleanable Applications
Replace cartridge when pressure differential is 30 psi
above start-up differential or when flow has diminished
to an unacceptable level, indicating cartridge is at
capacity.
Cartridge Removal
To remove filter cartridge,
drain filter housing. Remove
wing-nuts and lid. Hold
cross-bar in retainer nut and
pull upward to remove filter
cartridge and top plate from
filter housing. Follow cleaning
instructions described herein.
Lid Replacement
Replace wing-nuts system-
atically, rotating around filter.
“Finger tight” is normally suf-
ficient. However, in extreme
duty applications it may be
necessary to tighten to 75
inch lbs. of torque. Over-
tightening can cause dam-
age to the rim gasket.
When Cartridge Cleaning is Not Possible
For best results, clean
cartridges with pressure
nozzle using standard
hose. Direct spray at
an angle to remove
particulate (see photo).
Follow these directions
to remove oils, organic
matter, algae and mineral
deposits.
OILS: Soak cartridge in
a solution of tri-sodium
phosphate or similar
strong detergent (2 lbs. to
10 gallons of water). Soak
up to 12 hours for best
results. Rinse after bath.
ORGANIC MATTER, ALGAE: Use tri-sodium phosphate solution
as described above, plus 1 pint of liquid chlorine to kill organic matter
and algae. Soak cartridge one hour or longer until surface is no
longer “slippery.” Rinse after bath.
CALCIUM MINERAL DEPOSITS: Follow directions for “oils”
described above. Soak cartridge for approximately ten minutes in a
solution of one part of muriatic acid to twenty parts of water. Rinse
cartridge thoroughly with water.
Generally, it is not possible to clean Hurricane
®
filter cartridges when
filtering petroleum-base liquids, toxic substances, and one and
below micron applications.
Note: Pressure gauges are recommended to indicate when cartridge
cleaning or replacement is necessary.
Cartridge Care
Cartridge Cleaning in Aqueous Applications
Caution: Do not rinse cartridges with acid
until oils and organic matter are removed.
Use detergent first and follow with acid bath
for mineral removal. Flush cartridges with water
after muriatic or tri-sodium phosphate baths.
Cartridge Sub-assembly
Prior to installing cartridge
in filter, place top plate
on top of cartridge with
clip upward. Thread on
retainer nut securely for
proper seal.
