Installation and Operation Guide
E10 & E20 Prefilter Systems
E-Series prefilters are designed to increase the life of Everpure carbon water filters in
areas with an unusual amount of dirt in the water. With a 10 micron (nominal) rating,
the Everpure prefilter traps much of the dirt which contributes to scale buildup in ice
makers, and clogs the delicate orifices of other water-using equipment.

*The Standard EC110 Cartridge is provided with each Model E10 Filter. It is rated at 10
microns nominally and has a more-than-adequate life when filtering water with "normal" or
average dirt loads. The EC210 cartridge is provided with each E20 filter, which is also rated
at 10 microns nominally.
Applications and Features
• General purpose coarse filtration
• Pre-filtration for fine filters
• Reduces dirt, rust, oxidized iron and sulfide
• High-strength materials
Installation
The E10 coarse prefilter (part number EV9795-80) includes two 3/8" FPT optional reducer bushings. The E20 course pre-
filter (part number EV9795-90) includes two 1/2” FPT optional reducer bushings. Before starting the installation, be sure
to shut off both power and water to the equipment being served by your E-Series prefilter. For servicing purposes, a man-
ual shut-off valve should be installed in the water line.
IMPORTANT: Always use a NSF approved pipe dope or Teflon tape at all thread connections.
1. Select a suitable location for mounting the prefilter and install mounting screws 2 1/4" apart. The prefilter should be
close to the machine served and mounted ahead of the carbon filters for optimum performance.
2. Remove the prefilter from the carton and separate the bowl and head assembly. Set the bowl and cartridge aside. If
installing the EV9795-80 coarse filter, assemble (2) 3/8" FPT x 3/4" MPT bushings to the head (as needed). If
installing the EV9795-90 coarse filter, assemble (2) 3/4” MPT x 1/2” FPT bushings to the head (as needed). Be sure
to use a NSF approved pipe dope or teflon tape.
3. Check to be sure the o-ring on the bowl is sufficiently lubricated. If additional lubrication is needed, use only a high
quality food grade silicone lubricant.
