4.0 OPERA
TION AND MAINTENANCE
The operation and maintenance of your GE Osmonics E4H Machine is relatively simple but
requires regular data recording and routine preventative maintenance. We cannot emphasize too
strongly the importance of filling out the daily log sheet during each operating shift. A data sheet
was filled out upon start-up containing pertinent facts on the operation of your machine. These
two records are invaluable in diagnosing the performance of the equipment and must be kept for
reference. If you have questions concerning the operation of your machine or the method of data
recording, contact the GE Osmonics Application Engineering Department.
The three preventative maintenance procedures which must be done on a regular basis are as fol-
lows:
1. Change the pre-filter cartridge.
2. Flush the machine daily.
3. Clean the machine with approved GE Osmonics cleaners.
See the following sections for specific maintenance procedures.
4.1 Daily Log Sheets
A Daily Log Sheet (Section 10.0) which includes general operating conditions (pressures,
flows and concentrations) and routine or special maintenance (pre-filter changes, flushing,
cleaning, etc.) must be kept. Copies of the log can be made from the template. A copy of
this log sheet will be required by GE Osmonics if a warranty question arises.
4.2 Pre-Filter Cartridge
A 5-micron pre-filter is factory-installed to protect the membrane elements and valves
from particles which may be in the feed water. The pre-filter uses two 20-inch (50.8-cm)
diameter, 5-micron nominal rated cartridges. To order replacements, contact your
distributor.
The pre-filter cartridges must be replaced, at a minimum, once per week or after every 100
hours of operation, whichever comes first. A pressure drop of 8 psig (0.6 bar) across the
filter or more during operation indicates one or more cartridges need changing. Use only
Osmonics approved filters rated for 5 microns or less. Do not attempt to clean used
filters - install new replacements.

TANT NOTE: Failure to change the pre-filter according to these requirements
will void the warranty.
