Wrapper Removal and Installation

Wrapper Removal Steps:

1. Remove the two security screws from the front panel. (See Fig. D(i)). Ensure screws thread into the bushing correctly, avoiding horizontal threading.
2. Gently pull the wrapper down and rotate it to a downward position. (See Fig. D(ii)).
3. To remove the wrapper, hold each side and gently pull it up and out of the pivoting bracket. (See Fig. D(iii)).

CAUTION: The wrapper drops and swings when security screws are removed. Do not lean on the wrapper. Do not use power tools to tighten; do not overtighten.

Wrapper Re-attachment Steps:

1. Ensure no plumbing or external objects are below the wrapper within the specified dimension (3.27" minimum) for it to swing out. (See Fig. D(iv)).
2. Removing the wrapper from the pivoting bracket is recommended for servicing. The wrapper can be left in place for quick serviceability. (See Fig. D(iii)).
3. When re-attaching the wrapper, ensure each side is engaged to the pivoting bracket. (See Fig. D(v)).
4. Rotate the wrapper up and under the shroud. Align the through holes on the wrapper with the plastic bushing threads on the frame before engaging the security screws. Ensure the screw is angled relative to the ground and perpendicular to the wrapper surface before engagement. Hand-tighten before using a hand tool to prevent cross-threading.
5. Four plastic bushings are located in the cross brace of the frame. The lower two are in use, and the top two are spares. (See Fig. D(iii)).

NOTE: The highlighted portion in red in Figure E indicates acceptable plumbing rough-in.

NOTE: To mitigate wrapper rotation interferences, zip tie lines (plumbing and electrical) running between cooler units to the waste line (PVC pipe).

Hanger Brackets Installation

1. Remove the hanger bracket fastened to the back of the coolers by removing one screw.
2. Determine your mounting configuration from the figures shown on pages 2-5. The refrigeration unit must be on the right-hand side.
3. IMPORTANT NOTE: If the Bottle Filler is to be mounted on the left-hand cooler, a basin assembly change will be needed. Refer to Configuration Instructions on page 10.
4. Mount the hanger bracket as shown in Figures 1-4 (Pages 2-5).
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 the wall using all six (6) 1/4" dia. mounting holes.
6. IMPORTANT: Maintain a 5-7/8" (150 mm) dimension from the wall to the centerline of the trap for proper fit.

Installation of Cooler

1. Refer to Fig. D(i) to D(iv), Pg. 6 for wrapper removal instructions.
2. Hang only the refrigerated cooler on the hanger bracket, ensuring it is properly seated in the slots on the cooler backs as shown in Figures 1-4.
3. Hang the non-refrigerated cooler on the hanger bracket, ensuring it is properly engaged in the slots on the cooler backs as shown in Figures 1-4.
4. Unband the loose wires in the refrigerated cooler for the filter communication board. Stretch them out, thread them through the left side of the refrigerated cooler and into the right side of the non-refrigerated cooler. Plug into the filter communication board located behind the filter head.
5. Secure each cooler frame to the wall by installing two screws and washers (not supplied) in the lower holes. Ensure screws engage in a structural member.
6. Connect the supply water to the filter 3/8" copper inlet tube.
7. Connect the waterline from the outlet of the filter to the inlet of the evaporator in the refrigerated cooler by inserting it into the quick connector.
8. Connect the waterline from the solenoid in the non-refrigerated cooler to the open 1/4" tee fitting in the refrigerated cooler.
9. Find your cooler configuration on page 11 and connect the drain assembly.
10. Install the trap.

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.

Bottle Filler Installation

1. Remove two (2) mounting screws with a 5/32" Allen wrench holding the Bottle Filler to the wall mounting plate (See Fig. 8). Do not discard these screws.
2. Remove the wall mounting plate from the Bottle Filler (See Fig. 8). Place the wall mounting plate against the wall on top of the basin. Center the plate side-to-side with the basin. Mark the six (6) mounting holes with a pencil (See Fig. 1, Pg. 2). Place tape over the wiring harness connection on top of the cooler to prevent debris from falling into the connection (See Fig. 6, Pg. 7).
3. Remove the wall mounting plate from the wall. NOTE: Mounting plate MUST be supported securely. Add a fixture support carrier if the wall will not provide adequate support.
4. Install the wall mounting plate to the wall using six (6) 7/16" obround mounting holes (mounting bolts not included) (See Fig. 7, Pg. 7). Use appropriate fasteners for your wall type.
5. Install the gasket on the bottom of the Bottle Filler with the gasket support bracket & (2) screws. (See Fig. 8).
6. Route the 3/8" tubing through the opening in the bottle filler gasket and plug into the bulkhead fitting in the basin. Route the wiring harness through the gasket and plug into the connector on the top of the basin. Cut the water line to length before attaching to the bulkhead fitting.
7. Place the Bottle Filler on the four (4) hooks on the mounting plate installed on the wall.

Final Installation (Filter)

1. Remove the filter from its carton, remove the protective cap, and attach the filter to the filter head by firmly inserting it and rotating clockwise. Ensure the front-facing label is readable when installed. (See Fig. 12).
2. Turn the water supply on and inspect for leaks at both the cooler and the Bottle Filler. Fix all leaks before continuing.
3. Once the cooler and bottle filter have been inspected and any leaks corrected, plug the cooler into the wall.
4. Reinstall the two mounting screws from the first step. Caution: do not overtighten screws.
5. Once power is applied, the GREEN LED light on the bottle filler will illuminate, indicating good filter status, along with the LCD Bottle Counter.
6. Verify proper dispensing by placing a cup, hand, or any opaque object in front of the sensor area. Note: Initial dispenses may have air in the line, causing sputtering or a hazy appearance. Run water to flush the filter and purge air and fine carbon particles before use.
7. Once the unit tests out, install the Lower Panels back onto the water coolers. (See pages 12-13 for versatile wrapper installation).

Instructions for Replacing Filters

1. Refer to Fig. D(i) to D(iv), Pg. 6 for wrapper removal instructions.
2. Turn off the water supply and dispense water to relieve pressure.
3. Remove power by unplugging the cooler.
4. Turn the used filter counterclockwise a 1/4 turn to remove it from the filter head.
5. Remove the cap from the new filter and use it to seal the used filter.
6. Insert the new filter into the existing filter head and turn fully clockwise. Ensure the label on the front of the filter is readable once installed. (See Fig. 12).
7. Plug in the unit to restore power.
8. Turn on the water supply and run water through the filter to purge air and fine carbon particles before use. Visit elkay.com/filtration for additional details. Also, run water through the bottle filler until all air is removed and the water flow is clear.
