PARALLEL-202 PRE-FILTER (EV9100-24)
INSTALLATION
1. Shut off water and electrical power to all affected food service equipment.
It is important that the installation of the pre-filter be clean and sanitary. All water-contact parts shall be immersed in chlorinated water (a
capful of bleach per bucket of water) at the start of the installation procedure.
2. Disconnect electrical power and water from the high flow filter system to be served by the Parallel-202 Pre-Filter. Close the inlet water ball
valve on the high flow filter system. Disconnect the inlet water line from the high flow filter system ball valve.
3. Select a suitable location near the high flow filter system (not to exceed maximum of 10 ft.) for mounting the pre-filter and install mounting
hardware 16" apart (pre-filter mounting plate may be used as a template). The pre-filters overall dimensions are 26
1
⁄16" high x 28
3
⁄4" wide x 8
1
⁄2"
deep. Allow at least 2
1
⁄2" below the pre-filter to change out the cartridges. Be sure the mounting hardware is capable of supporting 42 pounds
(pre-filter weight when in service).
4. Unscrew both sumps from the pre-filter using the sump wrench, if necessary. Do not lose the O-ring seals. Remove the cartridges and set
aside with the sumps and O-rings (if removed).
NOTE: Be sure to use a high quality pipe joint compound or Teflon
®
tape on all threaded connections.
5. Install a 3/4" NPT x 3/4" barb connector into the the outlet tee of the pre-filter and the inlet water ball valve on the high flow filter system.
6. Measure distance between the barbs on the connectors and cut tubing (not supplied) to this length plus an additional 2". Slide two tubing
clamps (not supplied) onto the tubing and install the tubing ends fully onto the connector barbs (not supplied). Fully tighten the tubing clamps
to secure the tubing onto each connector barb.
7. Check that the sump O-ring is lubricated. If additional lubricant is required use only a high grade silicone lubricant. Install the O-ring in its
respective groove in the sump, remove protective wrap, position the cartridge on the guide seat in the bottom of the sump, then firmly screw
the sump into the cap and tighten with the provided sump wrench. DO NOT USE A PIPE WRENCH. Repeat this procedure for the second
cartridge and sump.
8. Connect the inlet water line disconnected from the inlet water ball valve on the high flow filter system the inlet water ball valve on the pre-
filter.
9. Turn on water to the pre-filter, place the pre-filter ball valve in the ON position (handle parallel to water flow), and press the red pressure
relief button on one cap to open the pressure relief valve, purging air from the high flow filter system. When water vents out, release the
button and repeat for the pressure relief on the second cap.
