Section 4:
System Maintenance
4.5 Hurricane Vessel Maintenance (vessel #2)
Ebbco Inc. recommends changing the filter cartridge on the 1st of each month or every 200 hours
of runtime; whichever comes first.
Filter Cartridge change out procedure:
1) Shut down the filtration system by turning both the system control switch and the rotary disconnect to
the off position.
2) Open the drain valve and completely drain the vessel of water.
3) Open the bleeder valve on top of the lid to purge any trapped air from the vessel.
Caution:
Failure to drain the hurricane vessel when performing a filter change out can
result in a charge of unfiltered water being sent to the High-Pressure Pump
4) Open unit by removing wing nuts followed by the lid.
5) Lift out the filter cartridge assembly and place it inside a 5-
gallon bucket.
6) Unscrew the cartridge retainer nut from the assembly.
7) Remove the filter cartridge from the top disk and wipe both
components with a rag to remove some of the debris.
8) Apply wax (part # WJF-STW) to the top and bottom seals of
the replacement filter cartridge, on the cartridge retaining nut
threads, and on both sides of the top disc that come into
contact with cartridge and the retaining nut.
9) Place the top disc on the replacement filter cartridge
while
the assembly is still outside of the vessel
. Reapply the
retainer nut and properly tighten so the top disc does not
rotate or spin freely.
Note: Do not change the filter while it is inside of the vessel
as the top disc WILL NOT seal properly and cause
performance issues.
10) Visually inspect the lid O-ring gasket. Ensure that it is free of
debris and sits flush inside of the O-ring groove. Replace the
O-ring gasket if it has become worn or damaged. It is
recommended that sufficient O-ring seal kits be kept in stock
at all times.
11) Replace the assembly into the hurricane vessel.
12) Replace the lid and lightly tighten each of the wing nuts.
Fasten down all of the wing nuts in a star-shaped pattern to
evenly disperse pressure across the lid. Over-tightening can
cause damage to the O-ring gasket, which may lead to an
uneven leaking seal.
13) Restore power to the CLS. Place a rag over the bleeder valve
and slightly open the valve to release any trapped air inside of
the vessel; close the bleeder valve once all the air is purged
and fluid starts to flow out of the valve.
Note: The operator must apply wax lubricant (part # WJF-STW) to the top and bottom seals of the
filter cartridge and on the top and bottom of the top disc surface that come into contact with the
cartridge and retainer nut. This must be done prior to filter cartridge installation back into vessel #
2. Ensure that top disc does not rotate or spin freely once reinstalled.
