ELKAY EZWS-ERPB8-RF Retrofit Bottle Filling Station

IMPORTANT
THIS IS AN INDOOR APPLICATION ONLY.
ALL SERVICES ARE TO BE PERFORMED BY AN AUTHORIZED SERVICE PERSON.

CAUTION: Review these instructions before beginning installation. Be sure that installation conforms to all plumbing, electrical, and other applicable codes.

WARNING: When the installation is complete, ensure these instructions are left in the plastic bag provided inside the installed unit for future reference.

WARNING: Service is to be performed by authorized service personnel only.

NOTE: It is common practice to ground electrical hardware such as telephones, computers, and other devices to available water lines. This can, however, cause electrical feedback in the plumbing circuit, which results in an “electrolysis” effect occurring in the fountain. This may result in water that has a metallic taste to it or a noticeable increase in the metallic content of the water. When inspecting the plumbing circuit, remember the line may be grounded some distance from the installation and may occur outside the building or area in which the unit is being installed. This condition can be avoided (in most cases) by using recommended materials during installation. Any drain fittings provided by the installer should be made of plastic which will electronically isolate the fountain from the remainder of the building’s plumbing circuits.

Typical current installation with fountains and panels removed. 1 Disassemble the current Bi-Level Refrigerated fountain installation.

1. Prepare for conversion. Turn off the electrical power and water supply to an existing installation.

2. Disassemble the current installation see (Fig. 2).

   • Remove existing fountains and plumbing connection lines.
   • Remove upper and lower panels
   • Remove the left-hand mounting frame

3. Install a new mounting frame into the left-hand side of the wall opening.

   • Secure mounting frame to wall opening and adjacent frame.
   • Use all fastener holes to secure the frame properly.

4. (For LZWS-ERPB8-RF) If an existing filter is not present, install the filter bracket on the chiller (Fig. 4), then install the filter head to the bracket, plumb from the filter outlet to the chiller inlet with ¼” poly tubing, and ¼ x ¼ union, install the filter.

5. (For EZWS-ERPB8-RF) Verify that a strainer is installed on the water supply line to the chiller (Fig. 5).

6. Install the chiller on the shelf, and install ¼ x ¼ x ⅜ tee on the chiller output tube. With the back panel standing close to the frame, connect the ⅜” poly tube from the bottle filler to the chiller outlet tee.

7. Install reset switch for bottle filler (Fig. 7). Snap the switch into position after locating wires through the slot. Wrap up the excess cord.

8. Hang the main panel on the mounting frame hanger. Make sure the power cord, reset switch wire & poly tube do not get pinched between the panel & mounting frame. Ensure the panel engages at the top. Align fountain holes with mounting frame holes.

9. Remove the protective coating from the main (upper) panel.

10. Install fountains with (4) 5/16-18 HHMS, (4) 5/16-18 nuts & (2) support brackets (Item 3) (from original installation) (Fig. 7). Connect the ¼” water lines from the fountain to the remaining opening on the tee at the remote chiller (cut lines to fit as needed), (Test fit refrigerated panel to make sure there is a tight joint between it & the main panel before fully tightening mounting screws.)

11. Attach waste tubes (1-1/4” O.D.) to 1-1/4” O.D. slip trap. The trap on the bottle filler side must be 1-1/2” O.D. (Traps and connection fittings provided by others).

12. Drill a 5/32” (.156”) diameter mounting hole in the right-hand frame to secure the lower right corner of the upper panel.
    • Center the hole in the tab opening.
    • Secure the panel to the frame with (a screw from kit Item 8).

13. Make final water supply connections. Turn on the water supply, and check for leaks. Repair leaks as required.
    • These products are designed to operate on 20-105 PSI supply line pressure. If inlet pressure is above 105 PSI, a pressure regulator must be installed in the supply line.
    • (Caution: Any damage caused by connecting these products to a supply line with pressure lower than 20 PSI or higher than 105 PSI IS NOT covered under warranty.)

14. Make electrical connections to the bottle filler and remote chiller. The LCD Bottle counter should illuminate. Refer to BF11 Program instructions for additional details on Bottle Filler setup.

15. Verify proper dispensing from the bottle filler by placing a cup, hand, or any opaque object in front of the sensor area and verify water dispenses. Note: the first initial dispenses might have air in the line which may cause a sputter. This will be eliminated once all air is purged from the line. A steady stream of water assures all air is removed. The sensor has a 20-second maximum ON time. It may be necessary to step away from the beam a few times to purge all air. Check for leaks.

16. Reconfirm the installation has no leaks. Install the lower (louver) panel.

BF11 – BF12 PROGRAM SETTING THE CONTROL BOARD

VERIFY CONTROL BOARD SOFTWARE

1. To verify the software program of the control board the unit will need to be shut down and restarted. The chiller (if present) does not need to be shut down and restarted.
2. Shut down the unit by unplugging the power cord from the wall outlet or switching off the circuit breaker to the unit.
3. Restart the unit by plugging the power cord back into the wall outlet or by switching on the circuit breaker to the unit.
4. Upon start-up, the bottle count display will show the software designation of BF11 or BF12.

ACCESSING THE PROGRAMMING BUTTON

1. To access the program button, remove the bottom lower louvered panel (Fig. 7) by removing the lower panel screws. The reset button is located on the mounting bracket.

RESET THE FILTER MONITOR

1. Instructions apply to filtered units only.
2. Depress the program button for approximately 2 seconds until the display changes then release. The display will change and scroll through two messages:
   • “RST FLTR” – Reset Filter Monitor
   • “SETTINGS” – System Settings Sub Menu If the program button is not pushed again the display will scroll through the two messages above for three cycles and then default back to bottle count and be back in run mode.
3. When the display changes to “RST FLTR”, depress the button again. The display will change to show “FLTR =”. Depress the button again and the display will show “FLTR =0”
4. The Green LED should be illuminated indicating that the visual filter monitor has been reset.

SETTING THE RANGE OF THE IR SENSOR WHERE APPLICABLE

1. Depress the program button for approximately 2 seconds until the display changes then release. The display will change and scroll through two messages:

   • “RST FLTR” – Reset Filter Status LED
   • “SETTINGS” – System Settings Sub Menu
     If the program button is not pushed again the display will scroll through the two messages above for three cycles and then default back to bottle count and be back in run mode.

2. When the display changes to “SETTINGS”, depress the button again. The display will change to show

   • “RNG SET” – Range set for IR sensor.
   • “UNIT TYP” – Type of unit (REFRIG or NON-RFRG)
   • “FLT SIZE” – Select filter capacity
   • “RST BCNT” – Reset bottle count

3. When the display shows “RNG SET” push the program button once the display will show the current value (can be 1 – 10) e.g. “RNG = 3”.

4. Once the display shows the current value push the program button to scroll through value of 1 – 10. Select the desired range setting, “1” being closest to the sensor and “10” being farthest away.

5. Once the range is selected allow approximately 4 seconds to pass and then the display will go back to the bottle counter and be in run mode.

6. Test bottle filler by placing the bottle or hand in front of the sensor to make sure water is dispensed.

TROUBLESHOOTING & MAINTENANCE

Orifice Assembly: Mineral deposits on the orifice can cause water flow to spurt or not regulate. Mineral deposits may be removed from the orifice by poking with a small round file not over 1/8” diameter or using a small diameter wire.

DO NOT file or cut orifice material.

Actuation of Quick Connect Water Fittings: Cooler is provided with lead- free connectors which utilize an o-ring water seal. To remove the tubing from the fitting, relieve water pressure, and push in on the gray collar while pulling on the tubing. (See Figure 12) To insert the tubing, push the tube straight into the fitting until it reaches a positive stop (approximately 3/4”).
