IMPORTANT! INSTALLER PLEASE NOTE.

THE GROUNDING OF ELECTRICAL EQUIPMENT SUCH AS TELEPHONE, COMPUTERS, ETC. TO WA TER LINES IS A COMMON PROCEDURE. THIS GROUNDING MA Y BE IN THE BUILDING OR MA Y OCCUR A WA Y FROM THE BUILDING . THIS GROUNDING CAN CAUSE ELECTRICAL FEEDBACK INTO A FOUNT AIN, CREA TING AN ELECTROL YSIS WHICH CAUSES A MET ALLIC T ASTE OR AN INCREASE IN THE METAL CONTENT OF THE WA TER. THIS CONDITION IS A VOIDABLE BY USING THE PROPER MA TERIALS AS INDICA TED. ANY DRAIN FITTINGS PROVIDED BY THE INST ALLER SHOULD BE MADE OF PLASTIC T O ELECTRICALLY ISOLA TE THE FOUNT AIN FROM THE BUILDING PLUMBING SYSTEM. WE SUGGEST THA T THE BOTTLE FILLING ST A TION AND W A TER COOLER BE PROTECTED BY A GROUND F AUL T CIRCUIT INTERRUPTER (GFCI).

INSTALLER

EZWSR Bottle Fillers are among the easiest to install on the market today. To insure you install these models easily and correctly, PLEASE READ THESE SIMPLE INSTRUCTIONS BEFORE STARTING THE INSTALLATION. CHECK YOUR INSTALLATION FOR COMPLIANCE WITH PLUMBING, ELECTRICAL, AND OTHER APPLICABLE CODES. After installation, leave these instructions with the Cooler for future reference.

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. 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) Cut out the Drain Mat template located on the last page of the manual and place the template on rear left side of the EZ cooler basin.

4) Locate 1-3/8” diameter hole on left side of the template (See FIG. 2). Mark center of hole on basin with pencil.

5) Remove Basin Assembly by loosening four (4) screws two on each side of cooler as shown in Fig. 5. Disconnect water line “A” from bubbler at the evaporator tank (See Fig. 3). 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. 5. 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. 3B). 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 proceedure 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. 3 or 3B). 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.

3) Reonnect the water inlet to the inlet of the evaporator (See Fig. 4 or 4B).

4) Cut a 12” long piece of poly tube (besure to insulate poly tube with supplied insulation tubing) and insert one end into the outlet side of the evaporator “D” (See Fig. 4 or 4B), connect Tee to other end of tube.

5) Cut a 12” long piece of poly tube (besure 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. 4 or 4B).

PRESSURIZATION OF WATER SYSTEM

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. 4A).

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 5).

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.
