INSTALLATION MANUAL

To insure you install this Kit easily and correctly, PLEASE READ THESE

SIMPLE INSTRUCTIONS BEFORE STARTING THE INSTALLATION. CHECK

YOUR INSTALLATION FOR COMPLIANCE WITH PLUMBING, ELECTRICAL, AND

OTHER APPLICABLE CODES.

IMPORTANT

THIS IS AN INDOOR APPLICATION ONLY.

ALL SERVICE TO BE PERFORMED BY AN

AUTHORIZED SERVICE PERSON.

IMPORTANT! INSTALLER PLEASE NOTE.

THE GROUNDING OF ELECTRICAL EQUIPMENT SUCH AS TELEPHONE, COMPUTERS, ETC. TO WATER LINES

IS A COMMON PROCEDURE. THIS GROUNDING MAY BE IN THE BUILDING OR MAY OCCUR AWAY FROM

THE BUILDING. THIS GROUNDING CAN CAUSE ELECTRICAL FEEDBACK INTO A FOUNTAIN, CREATING AN

ELECTROLYSIS WHICH CAUSES A METALLIC TASTE OR AN INCREASE IN THE METAL CONTENT OF THE

WATER. THIS CONDITION IS AVOIDABLE BY USING THE PROPER MATERIALS AS INDICATED. ANY DRAIN

FITTINGS PROVIDED BY THE INSTALLER SHOULD BE MADE OF PLASTIC TO ELECTRICALLY ISOLATE THE

FOUNTAIN FROM THE BUILDING PLUMBING SYSTEM. WE SUGGEST THAT THE BOTTLE FILLING STATION

AND WATER COOLER BE PROTECTED BY A GROUND FAULT CIRCUIT INTERRUPTER (GFCI).

WATER COOLER PREPARATION

●Remove Lower wrapper on the cooler by removing the (4) screws using a 5/16 nut driver

●Shut o󰀨 water to the cooler

●Remove water pressure by pressing on any of the cooler push bars until no water comes out of the bubbler

●Unplug the water cooler

●Remove the P-trap from the cooler drain

1. Remove the (4) screws – 2 per side on the upper shroud using the Torx bit or Allen

Wrench. (See Fig. 1) Note: The kit is for refrigerated units only.

2. Take a black marker and mark the water line where it enters the base of the evaporator.

This will ensure the water line is reinserted fully later. Fig. 2 & 3

Fig. 2 Fig. 3

3. Remove the water line from the evaporator. Have a bucket ready to catch water

coming from the evaporator.

4. Lift the basin shroud assembly, tilting forward towards the front of the water cooler and

unplug the two switch wires. One on the solenoid and one on the cold control. Once

both wires are free lift the assembly completely o󰀨.

5. Turn the basin/shroud assembly over on a table so that it is sitting on the basin.

6. Locate the serial number on the data label and write it down in permanent marker on

the blank label on the bottom of the new shroud.

7. Loosen the clamp on the drain and remove it and the plastic drain.

8. Remove the basin from the shroud by removing the four screws with the Torx bit or

Allen Wrench. Note: If your shroud has a regulator installed it will need to be

removed too.

9. Place the new shroud on the basin and attach it using the screws removed.

Note: If a regulator was removed from the old shroud it will need to be inserted

in the new shroud.

10. Insert the clamp and plastic drain into the rubber drain boot and tighten.

11. Using a Flat head screwdriver remove the plastic cap covering the electricals on the

compressor. Fig. 4

12. Remove the white wire from the compressor relay and the black wire from the overload. Leave the fan wires connected. Fig 5 & 6

13. Remove the power cord ground connection on the frame using the ¼ nut driver. Keep this

screw it will be needed to connect the ground wire on the new power cord. Fig. 7

16. Measure 23 inches from the plug end of the power cord and place the strain relief on

the cord at that point. Fig. 9

17. Squeeze the strain relief and place in the slot in the bracket that the old power cord

was removed. Push up until it locks into place. Fig. 10

Fig. 9

14. Using pliers, squeeze the strain relief on the power cord and pull down to remove the cord

from the bracket. Fig 8

15. Remove all remaining wires from the solenoid and cold control and discard.

19. Connect both female connections on the power cord to both open terminals on the cold

control. It does not matter which connector goes on which terminal. If the connections

do not reach, spread the wire apart more to gain length. Fig. 12

18. Put the ground screw in the ring terminal on the green ground wire on the power cord.

Tighten the screw back into the frame where the old ground wire was connected.

Tighten the screw so that the terminal will not turn. To make sure that the grounding

connection is secure, use a multi-meter and check for continuity. Place one probe on

the round connector on the plug and the other probe on the frame. Fig. 11

20. Follow the wires on the power cord that will connect to the compressor. The side of

the power cord connected to the cold control will need to be connected to the overload

connection on the compressor and the side of the cord coming from the connector

block on the cord will connect to the relay on the compressor. Fig. 13

22. Connect the black wire from the kit. The female connector is connection on the wire is connected to the piggyback terminal on the cold control and

the other end is connected to either one of the empty terminals on the solenoid. Fig. 15 & 16

NOTE: Some models have a di󰀨erent solenoid and location, however the wiring process remains the same.

23. Place the basin shroud assembly back on to the cooler frame and connect the sensor

wires. Connect the black wire to the piggyback terminal on the solenoid, the red wire

on the open terminal on the solenoid and the white wire to the white wire on the power

cord. Fig. 17

Fig. 17

21. Replace the cover over the compressor electricals. Place the slot on the cap on the lower arm on the compressor, slide all the wire into the large

slot in the cap. Rotate the cap upwards and push until it snaps into place. Fig. 14a, 14b & 14c
