WATER COOLER PREPARATION
1) Remove lower front panel of watercooler by removing the four (4) screws from
the bottom of cooler. (See FIG. 1) NOTE: For Two Level Models the Bottle Filling
Unit should be mounted to the higher unit. Both lower front panels and basin
assemblies will need to be removed.
2) Power OFF circuit that the water cooler is connected to by switching the
circuit breaker to the “OFF” position or by removing the fuse to the circuit.
Remove the water cooler plug from the outlet and shut off water supply.
3) Locate Drain Mat and place on back of EZ cooler basin to use as a template.
4) Locate 1-3/8” diameter hole on left side of Drain Mat (See FIG. 2). Mark
center of hole on basin with pencil. Remove the drain mat from the cooler
(DO NOT THROW AWAY! It will be needed for bottle filler installation).
5) Remove Basin Assembly by loosening four (4) screws two on each side of
cooler as shown in Fig. 3. Disconnect water line “A” from bubbler at the
evaporator tank (See Fig. 7). NOTE: When disconnecting water lines use a
container to catch any water running out of the lines. Disconnect basin
assembly from drain trap. Lift basin assembly straight up to remove, and
disconnect two wires from push bar switches. (Note: This will allow easier
assembly of water filter to unit and pressurization of the unit.)
EWF3000 WATERSENTRY PLUS FILTER INSTALLATION
NOTICE: Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after the system.
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) Remove filter bracket from filter head assembly and flip it over and reinstall it
to the filter head (see Fig. 4).
3) See filter instructions for filter assembly. Insert 3/8” elbow fitting into the
inlet side of filter head, insert 1/4” polytube or 1/4” x 90° elbow into outlet side
of filter head prior to mounting the filter head assembly into the cooler.
4) Mount filter head as shown in Fig. 4, using the filter mounting bracket and
screws supplied. For Two-Level units the filter must be mounted to the L.H.
non-refrigerated unit at the same location as shown in Fig. 4.
PRESSURIZATION OF WATER SYSTEM
1) Remove water inlet (B) and outlet (C) from solenoid valve (See Fig. 7).
NOTE: When disconnecting water lines use a container to catch any water
running out of the lines.
2) 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. 5). Ends of tubing
must be cut square and free of burrs and sharp ends that could cut or nick the
o-rings.
3) Remove the 3/8” copper water inlet from the evaporator (See Fig. 7a).
4) Connect the outlet of the filter to the inlet of the evaporator using the 1/4"
O.D. poly tubing and 1/4" union supplied (See Fig. 8 or 8A).
5) Cut a 12” long piece of poly tube and insert one end into the outlet side of
the evaporator “D” (See Fig. 8), connect Tee to other end of tube.
6) Cut a 12” long piece of poly tube and insert into the Tee and the other end
into the inlet side of the solenoid valve “E”.

TWO-LEVEL MODIFICATION OF WATER SYSTEM
NOTE: Two-Level water systems are already plumbed for pressurization.
STANDARD TWO-LEVEL MODELS
Follow instruction 2 thru 4 under “Pressurization of water system” to attach
filter to water system. The non-refrigerated side must be removed from the wall
in order to remove the basin assy. and install the filter head assy.
1) Remove the Two-Level Cover Plate from the right hand side of the non-
refrigerated unit in order to access the rear Basin Assy. screw.
2) Cut poly tube “H” between the existing tee and the solenoid valve of the L.H.
unit.
3) Insert supplied 1/4” Tee in water line “H” where it was just cut (See Fig. 8A).
TWO-LEVEL REVERSED MODELS
Follow instruction 2 thru 4 under “Pressurization of water system” to attach
filter to water system. The non refrigerated side must be removed from the wall
in order to remove the basin assy. and install the filter head assy.
1) Remove the Bi-Level Cover Plate from the left hand side of the refrigerated
unit in order to access the rear Basin Assy. screw (See Fig 3).
2) Cut poly tube “H” approximately 3” from the left side of the existing tee.
3) Insert supplied 1/4” tee in water line “H” where it was just cut.
DRAIN MAT ASSEMBLY AND CARE
1) Insert a nut into each of the four hex pockets on the bottom side of mat.
2) Place Drain Cover on mat and install the four screws as shown in Fig. 13.
Note the two shorter screw are used at the back of the cover. It is recom-
mended that the cover be removed and the drain and drain cover be cleaned
weekly. To dis-assemble or re-assemble the drain cover to the mat the mat can
be picked up from the front to access the nuts beneath.
