Bi-Level MODIFICATION OF WATER SYSTEM
NOTE:
Bi-Level water systems are already plumbed for pressurization.
STANDARD Bi-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 Bi-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 (See Fig. 6A or 6C).
3) Insert supplied Tee in water line “H” where it was just cut (See Fig. 7A or 7C).
Bi-Level Versatile 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 8).
2) Cut poly tube “H” approximately 3” from the left side of the existing tee.
3) Insert supplied tee in water line “H” where it was just cut.
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 Bi-Level Models the Bottle Filling
Unit can be mounted to the higher or lower unit. Both lower front panels and basin
assemblies will need to be removed.
1a) For units with model no’s. ending with 1, 1A, 2 or 3 these units will need to be
removed from the wall in order to remove the basin assembly(s).
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) Remove Basin Assembly by loosening four (4) screws two on each side of
cooler as shown in Fig. 8. Disconnect water line “A” from bubbler at the
evaporator tank (See Fig. 6). 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.)
5a) For units referenced in step “1a”. Remove Basin Assembly by
loosening four (4) screws two on each side of cooler as shown in Fig. 8. Remove
2 screws from top back of unit to remove the “L” bracket. Remove 1 screw from
left side of cross brace in front of unit that retains the drain support. Disconnect
water line “A” from regulator at the evaporator tank (See Fig. 6B). 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 un-
known 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) See filter instructions for filter assembly. Insert 3/8” elbow fitting into the inlet
side of filter head, insert 1/4” poly tube or 1/4” x 90° elbow into outlet side of filter
head prior to mounting the filter head assembly into the cooler.
3) Mount filter head as shown in Fig. 9, using the filter mounting bracket and
screws supplied. For Bi-Level units the filter must be mounted to the L.H.
non-refrigerated unit at the same location as shown in Fig. 9.
PRESSURIZATION OF WATER SYSTEM
NOTE: This procedure MUST be performed on ALL SINGLE EZ WATER
COOLERS
or the bottle filling unit
WILL NOT perform properly!
1) Remove water inlet (B) and outlet (C) from solenoid valve (See Fig. 6 or 6B).
NOTE: When disconnecting water lines use a container to catch any water run-
ning 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. 10). Ends of tubing must be
cut square and free of burrs and sharp ends that could cut or nick the o-rings.
3) 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. 7 or 7B).
4) Cut a 12” long piece of poly tube (be sure to insulate poly tube with supplied
insulation tubing) and insert one end into the outlet side of the evaporator “D”
(See Fig. 7 or 7B), connect Tee to other end of tube.
5) Cut a 12” long piece of poly tube (be sure to insulate poly tube with supplied
insulation tubing) and insert into the Tee and the other end into the inlet side of
the solenoid valve “E” (See fig. 7 or 7B).
