EZWS-ERFP8-RF ezH2O Retrofit Bottle Filling Station

IMPORTANT
THIS IS AN INDOOR APPLICATION ONLY. ALL SERVICE TO BE PERFORMED BY AN AUTHORIZED SERVICE PERSON.
Review these instructions before beginning installation. Be sure that installation conforms to all plumbing, electrical and other applicable codes.
When installation is complete, ensure these instructions are left in the plastic bag provided inside the installed unit for future reference.
Service 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 which has a metallic taste to it or has a noticeable increase in the metallic content of the water.
When inspecting 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.

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

2. Disassemble the current installation (See Fig. 2).
   • Remove existing fountains and plumbing connection lines.
   • Remove upper and lower panels
   • Remove left hand mounting frame

3. Install new mounting frame into left hand side of wall opening.
   • Secure mounting frame to wall opening and adjacent frame.
   • Use all fastener holes to secure the frame properly.

4. (For LZWS-ERFP8-RF) If an existing filter is not present, install filter bracket on 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 filter.

5. (For EZWS-ERFP8-RF) Verify that a strainer is installed on the water supply line to the chiller (Fig. 11).

6. Install chiller on shelf, install ¼ x ¼ x ⅜ tee on chiller output tube. With the back panel standing close to the frame, connect 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 slot. Wrap up the excess cord.

8. Hang main panel on 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 protective coating from main (upper) panel.

10. Install fountains with (4) 5/16-18 HHMS, (4) 5/16-18 nuts & (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. 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 right hand frame to secure the lower right corner of the upper panel.
    • Center the hole in tab opening.
    • Secure the panel to the frame with (screw in kit Item 8).

13. Make final water supply connections. Turn on water supply, 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 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 maxi mum 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.

NOTE: The following items are not used with the  converted installation:
– One Fountain Assembly
– Wall Frame – Left Side
– Upper Panel
– Lower (Louver) Panel
BF11 – BF12 PROGRAM

SETTING THE CONTROL BOARD

V ERIFY 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

TROUBLESHOOTING & MAINTENANCE

Orifice Assembly: Mineral deposits on 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.

Figure 11 – Water Supply Connections

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