HANGER BRACKETS & TRAP
INSTALLATION
1) Remove hanger bracket fastened to back of cooler by removing one (1) screw.
2) Mount the hanger bracket as shown in Fig. 2.
NOTE: Hanger Bracket MUST be supported securely. Add xture support carrier if 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 Fig. 2.
4) Remove the four (4) screws holding the lower front panel at the bottom of 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
ts 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 tube, check for leaks after re-assembly.
7) Plug in electrical power. Unit must have electrical power to have water ow.
START UP
Also See General Instructions
8) Stream height is factory set at 35 PSI. If supply pressure varies greatly from this, adjust screw located on the right knee clearance area of the
underside of the Basin Shroud. CW adjustment will raise stream and CCW adjustment will lower stream. For best adjustment, stream should
hit basin approximately 6-1/2” (165mm) from bubbler on the downward slope of the basin.
NOTE: If continuous ow occurs at the end of the compressor cycle, turn cold control counterclockwise 1/4 turn.
9) Replace the front panel ensuring that the metal wrapper is secured inside of the upper shroud. Replace all four screws previously removed.
SENSOR RANGE ADJUSTMENT:
The electronic sensor used in this cooler is factory pre-set for a “visual” range of 18" to 24" (457mm to 610mm). If actual range varies greatly
from this or a dierent setting is desired, follow the range adjustment procedure below:
- Using a small tip screwdriver, locate range adjustment screw through the small hole between the sensor lenses (See Page 1.)
Turn this screw clockwise to increase range and counterclockwise to decrease range (See Fig. 3).
CAUTION: Complete range of sensor is only one turn of the adjusting screw.
SENSOR WITH VISUAL FILTER MONITOR (VFM) – LZO SERIES:
The electronic sensor includes LED lter status indicators that are factory preset to monitor lter 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 and indicates the following:
Green LED (Good) indicates that the lter is operating within 0% - 80% of its life.
Yellow LED indicates that the lter is operating within 80% - 100% of its life.
Red LED (Replace) indicates that the lter needs to be replaced since it has reached end of lter life.
Once power is applied to the water cooler, if all three LED’s ash then the Green LED illuminates, this indicates that there is some l-
ter usage memory stored. When the Green LED comes on only, this indicates that the lter life is at absolute 0% of lter life. NOTE: You
may have some very minimal lter life in memory upon receiving water cooler due to factory functional testing.
NOTE: The lter status will be retained until reset (see resetting lter monitor). The lter monitor will retain its memory even during a
loss of power.
RESETTING VISUAL FILTER MONITOR (VFM):
In order to reset the visual lter monitor status LED’s, you must remove the access panel (item 21) underneath the front dispenser. With your
nger or straight blade screw driver, reach inside opening and depress the reset button located on the back of the sensor for a minimum of 1
second. (You may need a ashlight) Reinstall access panel and the Green LED should be illuminated indicating that the visual lter monitor has
been reset.
SENSOR CONTROL: If sensor fails to operate valve mechanism or operates erratically, check the following.
A. Ensure there are no obstructions within a 40 inch (1016mm) radius in front of cooler.
B. Check wire connections at the solenoid valve and sensor. CAUTION: Make sure unit is unplugged before checking any wiring.
C. Ensure proper operation of solenoid valve. If there is an audible clicking sound yet no water ows, look for an obstruction in the
valve itself or elsewhere in the water supply line.
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 nished
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 chemi-
cals or petroleum based or abrasive cleaners will void the warranty.

ASSEMBLY
Lower and Upper Shroud
To access the refrigeration system and plumbing connections, remove four screws from bottom
of cooler to remove the lower shroud. To remove the upper shroud for access to the pushbars,
regulator, solenoid valve or other components located in the top of the unit, remove lower shroud,
disconnect drain, remove four screws from tabs along lower edge of upper shroud, unplug two wires
and water tube.
Bubbler
To remove the bubbler, rst disconnect the power supply. The underside of the bubbler can be
reached through the access panel (Item 21, Page 2) on the underside of the shroud (Item 3).
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 tting per the
Operation Of Quick Connect Fittings section in the General Instructions. After servicing, replace the
access panel and retaining screw.
