HANGER BRACKETS INSTALLATION

1. Remove the hanger brackets fastened to the back of the cooler by removing one (1) screw.

2. count the hanger brackets as shown in Figures 2, 3, 4 or 5.
   NOTE: Hanger Bracket MUST be supported securely. Add a fixture support carrier if the wall will not provide adequate support. Anchor hanger securely to wall using all six (6) 1/4 in. dia. mounting holes
   INSTALLATION OF COOLER

3. Hang the cooler on the hanger bracket. Be certain the hanger bracket is engaged properly in the slots on the cooler back as shown in Figures 2, 3, 4 or 5.

4. Remove the four (4) screws holding the lower front panel at the bottom of the cooler. Remove the front panel by pulling straight down and set aside.

5. Connect water inlet line–See Note 4 of General Instructions.

6. Install trap. Remove the slip nut and gasket from the trap and install them on the cooler waste line making sure that the end of the waste line fits into the trap. Assemble the slip nut and gasket to the trap and tighten securely.
   IMPORTANT: If it is necessary to cut the drain, loosen the screw at the black rubber boot and remove the tube, check for leaks after re-assembly.

7. Install bottle filler per page (11).

8. Plug-in electrical power. The unit must have electrical power to have water flow
   START UP Also See General Instructions

9. Stream height is factory set at 35 PSI. If supply pressure varies greatly from this, adjust the screw located on the right knee clearance area. CW adjustment will raise stream and CCW adjustment will lower stream. For best adjustment, stream should hit basin approximately 6-1/2” (165mm) from the bubbler on the downward slope of the basin.
   NOTE : If continuous flow occurs at the end of the compressor cycle, turn the cold control counterclockwise 1/4 turn.

10. Replace the front panel ensuring that the metal wrapper is secured inside of the upper shroud. Replace all four screws previously removed

CLEANING

Warm, soapy water or mild household cleaning products can be used to clean the exterior panels of the EZ coolers. Extra caution should be used to clean the mirror-finished stainless steel panels. They can be easily scratched and should only be cleaned with mild soap and water or Windex glass cleaner and a clean, soft cloth. Use of harsh chemicals or petroleum based or abrasive cleaners will void the warranty.

Service Instructions
Lower and Upper Shroud
To access the refrigeration system and plumbing connections, remove four screws from the bottom of cooler to remove the lower shroud. To remove the upper shroud for access to the push bars, regulator, solenoid valve or other components located in the top of the unit, remove the lower shroud, disconnect the drain, remove four screws from tabs along the lower edge of upper shroud, unplug two wires and water tube.
Bubbler

To remove the bubbler, first disconnect the power supply. The underside of the bubbler can be reached through the access panel on the underside of the upper shroud. Remove the access panel by removing the retaining screw. To remove the bubbler, loosen locknut from the underside of the bubbler and remove the tubing from the quick connect fitting per the Operation Of Quick Connect Fittings section in the General Instructions. After servicing, replace the access panel and retaining screw.

Switches Behind the Push Bar

The regulator in an EZ cooler is always held fully open by the use of a single regulator nut (See Fig. 6 or 7). Water is not dispensed until the pushbar is depressed to activate a switch which then opens a solenoid valve. When installing the regulator nut, the regulator spring must be depressed while turning the nut. To remove sidebars, from the inside compress the flared tabs and pull out carefully. To reinstall side pushbars, the front of the pushbar is inserted first. While keeping the switch depressed, snap the rear of the pushbar into position.

Bottle Filler Installation Instructions

1. Remove two (2) mounting screws with a 5/32” Allen wrench holding the top cover to Bottle Filler (See Fig. 9). Remove the top cover. Note do not discard mounting screws, they will be needed to reinstall the top cover.
2. Remove the wall mounting plate from the Bottle Filler. Place the wall plate against the wall on top of the basin. Centre the wall plate side to side with the basin. Mark the six (6) mounting holes with a pencil (See Fig. 2, 3, 4 or 5).
3. Remove wall mounting plate from the wall. NOTE: The mounting plate MUST be supported securely. Add a fixture support carrier if the wall will not provide adequate support.
4. Install wall mounting plate to the wall using six (6) 7/16” obround mounting holes (mounting bolts not included) (See Fig. 8). Use appropriate fasteners for your wall type.
5. Lay Bottle Filler on the water cooler basin and cut the insulation from tube even with bottom of gasket, remove this insulation from the 3/8” tube but do not discard it. Feed the power cord and waterline through the hole on top of water cooler. NOTE: To prevent scratching the basin place a towel or soft cloth over the entire basin when work-ing above it.
6. Install a gasket on the bottom of the bottle filler tower with a gasket support bracket & (2) screws (See Fig 11).
7. Feed power cord & 3/8” water line through hole in tower/basin gasket (See Fig 10).
8. With the power cord , wire(s), and waterline through a hole on top of the water cooler place the Bottle Filler on the three (3) angled tabs protruding from the wall mounting plate installed on a wall. Make sure round boss in gasket fits in hole of basin. (See Fig. 18, p.17).
9. Once the Bottle Filler is installed on wall plate tabs, water line, wire(s) and power cord are installed properly, push the top of Bottle Filler toward wall and line up top cover two (2) holes.
10. Reinstall Top Cover on Bottle Filler (See Fig. 9) with two mounting screws from Step 1 above. Caution, do not over tighten screws.
11. Install the remaining tube insulation to the water line from the bottle filler, and connect Bottle Filler waterline inside of the water cooler by connecting the 3/8” water line to the tee.
12. Install the filter cartridge , remove filter from a carton, remove the protective cap, attach the filter to filter head by firmly inserting into head and rotating filter clockwise.
13. Turn water supply on and inspect for leaks. Fix all leaks before continuing.
14. Once unit has been inspected for leaks and any leaks found corrected, plug Bottle Filler and unit into wall. Be sure to reinstall fuse to the circuit or switch the circuit breaker back to the “ON” position.
15. Once power is applied to Bottle Filler , the GREEN LED light should illuminate showing good filter status along with the LCD Bottle Counter.
16. Verify proper dispensing by placing cup, hand, or any opaque object in front of sensor area and verify water dispenses. Note: the first initial dispenses might have air in line which may cause a sputter. This will be eliminated once all air is purged from the line.
17. Once unit tests out, install Lower Panel back on water cooler(s). Unit is now ready for use.
