6a) For Two-Level model installations: Attach the purple and yellow wires from coolers to the purple and yellow wires on the back of the unit, purple to
purple, yellow to yellow.
7) Remove 3/8” to 1/4” reducing union from end of waterline, (do not throw away it will be needed later). Lay Bottle Filler on water cooler basin and cut
insulation from tube even with bottom of unit, remove this insulation from 3/8” tube, but do not discard. Fish the power cord, and waterline through the
hole on top of water cooler created from the “Water Cooler Preparation” section. NOTE: To prevent scratching the basin place a towel or soft cloth over the
entire basin when working above it.
8) With the power cord and waterline through hole on top of water cooler place Bottle Filler on the three (3) angled tabs protuding from the wall mounting
plate, installed on wall (See Fig. 11). Make sure rubber Drain Mat is installed properly on bottom of Bottle filler (See Cover Illustration).
9) Once Bottle Filler is installed on wall plate tabs, drain mat, water line, wire(s) and power cord are installed properly, push top of Bottle Filler toward wall
and line up top cover two (2) holes.
10) Reinstall Top Cover on Bottle Filler (See FIG. 10) with two mounting screws from step 1 above. Caution do not over tighten screws.
11) Install remaining tube insulation on to water line from bottle filler, connect Bottle Filler waterline inside to the water cooler by connecting the 3/8” water
line with the 3/8” to 1/4” union and short piece of poly tube that was previously installed to the tee. (See Fig. 8 or 8A).
12) Install filter cartridge, remove filter from carton, remove protective cap, attach filter to filter head by firmly inserting into head and rotating filter
clockwise. NOTE: If existing plumbing roughin locations (Drain, Water In, Electric Supply) do not allow the filter to be mounted inside the cooler
cabinet the filter can be installed horizontally below the unit see page 9. A retrofit kit is available to mount the filter beneath the cooler.
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 LZ 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 infront of sensor area and verify water dispenses. Note: the first intitial
dispenses might have air in line which may cause a sputter. This will be eliminated once all air is purged from the line. NOTE: If your Bottle Filler
Counter continuously advances, see page 7 for wiring changes to the non-refrigerated unit to correct the problem. The included adapter wires may
only be needed on Two-Level Units manufactured before JANUARY 2009.
17) Once unit tests out, install Lower Panel back on EZ water cooler(s). Units are now ready for use.
The electronic sensor includes LED filter status indicators that are factory preset to monitor filter life. The sensor monitors the “ON” time
of the water valve solenoid and keeps track of total time water is dispensed.
There are (3) LED’s that indicate the following:
Green: LED (Good) indicates that the filter is operating within 0% - 80% of its life.
Yellow: LED indicates that the filter is operating within 80% - 100% of its life.
Red: LED (Replace) indicates that the filter needs to be replaced since it has reached end of filter life.
TO CHANGE THE FILTER:
1) Remove the lower front panel of the watercooler by removing the four (4) screws
2) Turn inlet water valve off.
3) Open bubbler to relieve pressure build-up in the system.
4) Remove filter from head by rotating filter counterclockwise.
5) Remove new filter from carton, remove protective cap; cap may be placed on old filter to reduce the chance of water spilling from
filter housing.
6) Attach filter to filter head by firmly inserting into head and rotating filter clockwise.
7) Turn on water supply and hold open the bubbler on cooler until approximately 1 gallon of water is dispensed. This flushing
procedure purges air and fine carbon particles from the filter.
