EWF112,TWF112 WaterSentry® I KIT (Sediment, Taste & Odor Reduction)
EWF172, TWF172 WaterSentry® VII KIT (Lead, Cyst, Sediment, Taste & Odor Reduction)
These filter kits are designed to be used with the following
Elkay and Cordley/Temprite products.
1. EDG, TDG, EDP, TDP, EDV, TDV Series Point-of -Use
Water Coolers.
2. EBL, TBL, EBV, TBV Series Water Coolers with FV-122
Float Kits.
3. LKH-190 Hot Water Dispensers
4. LK-2156 Dispensing Valve with or without a chiller unit.
5. LK-1141 Bubbler with or without a chiller unit.
6. Independently in an undersink application. For
undersink applications, it is recommended that water
be dispensed through a dedicated valve or faucet
instead of the sink faucet due to the reduced flow
through the filter.
NOTICE: Do not use with water that is microbiologically
unsafe or of unknown quality without adequate
disinfection before or after the system.
General Installation Instructions
1. These filter kits must be installed in compliance with all
state and local laws and regulations governing the
installation and use of this product. Maximum inlet
water temperature 100°F (38°C).
2. Mount filter head in a suitable location, using the filter
mounting bracket and screws supplied. Allow enough
room under the filter head for installation and removal of
filter cartridge (13" minimum).
3. Connect the cold water supply to the filter through a
shut-off valve and 3/8" O.D. tubing (supplied by the
installer). For ease of servicing, the shut-off valve
should be located within easy reach of the filter.
NOTE: The inlet and outlet fitting supplied as
part of the filter head are John Guest Superseal
fittings that accept 3/8" O.D. tubing on the filter
inlet and 1/4" O.D. tubing on the outlet. They may
be used with copper, stainless steel, or semirigid
nylon or polypropylene tubing, with a rated working
pressure equal or greater than encountered in
application. Do not use soft or braided tubing.
4. CAUTION: If supply pressure will ever exceed
100 psi, install a pressure regulator to limit the
inlet pressure to the filter to 100 psi or below.
DO NOT ATTACH HOT WATER LINE TO FILTER.
To make connections on the filter head, loosen locknut.
Push the tube end past both o-rings to a positive stop in
the filter head recess - approx. 1", locknut may have to
be backed out a little more. Screw the locknut hand tight
to seal (See Fig. 1). Ends of tubing must be cut square
and free of burrs and sharp ends that could cut or nick
the o-rings.
5. Connect the outlet of the filter to the inlet of the union
using the 1/4" O.D. poly tubing and 1/4" union supplied.
6. Remove filter from carton, remove protective cap, attach
filter to filter head by firmly inserting into head and
rotating filter clockwise.

7. Follow the applicable instructions below for correct
flushing procedure and to complete the installation.
The flushing procedure must be followed to purge air
and fine carbon particles from the sytem.
8. Read and follow instructions for the installation of the
product to be used with the filter kit.
EDP, EDV Series Point-of-Use or EBL, EBV Series water
cooler with FV-122 float kit.
1. If water reservoir contains any water, drain completely
through cold water faucet.
2. Turn on water supply and immediately open cold water
dispensing faucet on cooler, holding faucet open until
approximately 1 gallon of water is dispensed. This
flushing procedure purges air and fine carbon particles
from the filter. When 1 gallon of water has been
purged through the cooler, allow the faucet to close
and the reservoir to fill.
3. Carefully inspect all water connections for leaks.
4. Dispense approximately 1/2 gallon of water through
the hot faucet. Unit is now ready for operation.
LKH-190 Hot Water Dispenser, LK-2156 Dispensing
Valve with or without a chiller tank, LK-1141 Bubbler
with or without a chiller unit, under sink application.
1. Open inlet water supply valve, open dispensing valve
or bubbler and allow approximately 1 gallon of water to
be dispensed. This flushing procedure purges air and
fine carbon particles from the filter.
2. Turn dispensing valve off and carefully inspect all water
connections for leaks.
3. Unit is now ready for operation.

Filter Replacement*
1.Turn inlet water valve off.
2.Open dispensing valve to relieve pressure build-up in
the system.
3.Remove filter from head by rotating filter counterclock
wise.
4.Remove new filter from carton, remove protective cap;
cap may be placed on old filter to reduce the chance of
water spilling from filter housing.
5.Attach filter to filter head by firmly inserting into head
and rotating filter clockwise.
*Optional Filter Monitor (Part No. 92640C)
counts gallon usage and provides an audible alert
when filter needs replacement. Alert is sounded only
when water is being dispensed; beeping is not continuous.
Requires 9VDC alkaline battery.
RATED OPERATING CONDITIONS
NOTE: The filter head contains an automatic
shut-off valve that stops the flow of water.
If the filter is removed inadvertently with-
out shutting off the incoming water.
Listed below are filters that will fit into the filter head
supplied with this kit. The labels on the filters are colorcoded as noted. Make certain that the correct filter is
being used for application. See Performance Data
