Section 4: System Maintenance
Always disconnect power and relieve pressure from the system before performing
any maintenance on this Filtration System
Always follow correct lock out procedures when working on this Filtration System
The system will require the following items to be maintained on a scheduled basis:
4.1 Closed Loop System Daily Check List
1) Lift the lid on the system’s clean tank and observe the water quality (the clean tank must be 100%
clean at all times).
2) Start the system pump by rotating the system pump control switch on the electrical panel.
3) Check the pressure differential on bag vessel inlet and outlet pressure gauges (vessel #1).
Note: The red service beacon on top of electrical panel will flash when the outlet pressure reaches
10 PSI, signaling that the bag filter inside of vessel #1 needs to be serviced. Allow 5 – 10 minutes
to elapse prior to changing the bag filter. Once the allotted time has passed perform the
maintenance to the bag filter, as described in section 4.4. Observing the pressure gauge at startup
will give you a good indication of how close you are to servicing the bag filter.
4) The hurricane filter cartridge typically will not get a large pressure differential. This filter should be
changed on a routine maintenance schedule. Ebbco Inc. recommends changing the cartridge on the
1st of each month, or *200 hours of operation (see maintenance section in manual for cleaning
procedure).
*Note: The material being cut and the abrasive being used may affect filter life.
5) Check the TDS meter on the front of the electrical panel. The TDS Meter is preset at the pump
manufacturer recommended settings. Your preset TDS level is 40.
TDS levels may spike during filter service or when make-up water is added.
This is normal, however the desired TDS level should return within a few
minutes (see maintenance section in this manual for Resin Bag information).
6) Open the lid to clean/dirty tank. First, the water should be overflowing from the clean tank into the
dirty tank. Second, the water in the clean tank must be clean at all times. Sending dirty water to High-
Pressure Feed Pump could result in catastrophic maintenance/damage.
7) Observe the water make-up float assembly. The water level in the dirty tank should maintain the
present float height with city water barely trickling in or shut off.
8) Start the High-Pressure Feed Pump. Your feed pump should be running at ~80 – 90 PSI.
Note: Pressure reading is before the High-Pressure Feed Pump is turned on; the pressure will
drop a couple of PSI after feed pump is turned on.
