4. OPERATION AND MAINTENANCE
The operation and maintenance of your GE Water & Process Technologies 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 should have been filled out upon start-up containing
pertinent facts on the operation of
y
our 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 Water & Process Technologies Technical Support Team. The three
preventative maintenance procedures, which must be done on a regular basis are as follows:
1. Change the pre-filter cartridge.
2. Flush the machine da
ily
.
3. Clean the machine with approved GE Water & Process Technologies cleaners.
See the following sections for specific maintenance procedures.
4.1 Daily Log Sheets
A daily log sheet, 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 Water & Process Technologies if a warranty question arises.
4.2 Pre-Filter
A 5-micron pre-filter is factory-installed to protect the membranes and valves from particles,
which may be in the feed water. The pre-filter uses two 20-inch (50.8-cm) diameters, 2-
micron nominal rated cartridges. To order replacements, see the standard parts list.
The filter cartridges must be replaced, at a minimum, once per week or after ever
y 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 GE
Water & Process Technologies approved filters rated for 5 microns or less. Do not attempt to
clean used filters - install new replacements.
