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 Figure 2.
NOTE: Hanger Bracket MUST be supported securely. Add fixture support carrier if wall will not provide adequate support. Anchor hanger securely to wall
using all six (6) 1/4 in. dia. mounting holes.
IMPORTANT:
5-7/8 in. (150mm) dimension from wall to centerline of trap must be maintained for proper fit.
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 Figure 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 fits into the
trap. Assemble the slip nut and gasket to the trap and tighten securely. The purple jumper wire (item 48) from the right hand refrigerated unit is to be
connected to the the purple jumper wire (item 48) located on the non-refrigerated left hand unit by removing the protective end caps and connecting the
male and female terminal connectors.
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 flow. 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 left side below the push bar assembly on
the crossbar. 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 flow occurs at the end of the compressor cycle, turn cold control (Item 38) 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 36 inches (914 mm). If actual
range varies greatly from this or a different 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 (24-36 inches/610-1168mm) is only one turn of the adjusting
screw.
SENSOR WITH VISUAL FILTER MONITOR (VFM) – LZO SERIES:
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. On LZOTL units, the sensor also monitors the water time on of the left hand unit
using a purple jumper wire. If the purple jumper wire is not installed, improper water usage will be calculated. There are (3) LED’s and indicates 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.
Once power is applied to the water cooler, if all three LED’s flash then the Green LED aluminates, this indicates that there is some filter usage memory
stored. When the Green LED comes on only, this indicates that the filter life is at absolute 0% of filter life. NOTE: You may have some very minimal
filter life in memory upon receiving water cooler due to factory functional testing.
NOTE: The filter status will be retained until reset (see resetting filter monitor). The filter monitor will retain its memory even during a loss
of power.
RESETTING VISUAL FILTER MONITOR (VFM):
In order to reset the visual filter monitor status LED’s, you must remove the access panel (item 45) underneath the front dispenser. With your finger
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 flashlight) Reinstall access panel and the Green LED should be illuminated indicating that the visual filter 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 flows,
look for an obstruction in the valve itself or elsewhere in the water supply line.

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, first disconnect the power supply. The underside of the
bubbler can be reached through the access panel (Item 45) on the underside of the
upper shroud (item 2). Remove the access panel by removing the retaining screw (item
46) . To remove the bubbler, loosen locknut (Item 10) from the underside of the
bubbler and remove the tubing from the quick connect fitting per the Operation Of
Quick Connect Fittings section in the General Instructions. After servicing, replace the
access panel and retaining screw.

BUBBLER DETAIL
NOTE:
When installing replacement bubbler and pedestal, tighten
nut (Item 10) only to hold parts snug in position. Do Not
Overtighten.

Cleaning the strainer
To clean the strainer, unscrew the cap of the
solenoid valve. Remove screen and rinse
thoroughly with water. Insert screen back
into solenoid valve and screw cap on. Make
sure the o-ring is placed properly.
Screen
O-ring
Cap
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 finished 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 chemicals or petroleum based or abrasive cleaners
will void the warranty.
