Service
For proper and safe servicing, please read these instructions completely.
DANGER
• All Service and Maintenance must be performed by an authorized service personnel.
• Disconnect electrical supply to the unit before any service work to reduce risk of electrocution.
• Shut o󰀨 water supply serving the unit before any service work to reduce risk of water damage.
CAUTION
• Tools/Items required but not provided, for Servicing:
a) Safety Glasses
b) Protective gloves
c) 5/16” (8mm) Hex Socket or Flathead Screwdriver
Service: Adjustments
1. Temperature Control: Factory set for 50ºF ± 5º (10ºC ± 2.8º) water under normal conditions. To adjust water temperature, turn screw on Item No.
25 clockwise for colder, counter clockwise for warmer.
2. Water Stream Height: Stream height is fact`ory set at 35 psig (0.24 MPa). If supply pressure varies greatly from this, adjust screw located on the
right knee clearance area side at bottom of the switch shroud. Clockwise adjustment will raise stream and Counterclockwise 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.
3. Water coming out of Bubbler continuously: When this occurs at the end of the compressor cycle, turn the cold control warmer (counterclockwise)
¼ turn.
Service: Inspection/Cleaning
• Inspect Cooler twice each year for proper operation and performance.
• Inspection of the unit will require disconnecting electrical supply, removal of panels, etc. and reassembly and return to service practices.
1. Cleaning: Warm, soapy water or mild household cleaning products can be used to clean the exterior panels. 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 chemicals or petroleum based or abrasive cleaners will void the warranty.
2. Bubbler: Mineral deposits on the orice can cause water ow to spurt or not regulate. Mineral deposits may be removed from the orice with a
small round le not over 1/8” (3 mm) diameter or small diameter wire.
• CAUTION : DO NOT le or cut orice material. Care must be taken not to damage the orice(s)
3. Condenser Fan Motor: Conrm condenser fan turns freely. If the condenser fan does not spin freely, have an authorized service personnel replace.
4. Ventilation: Cabinet louvers and condenser ns should be periodically cleaned with a brush, air hose or vacuum cleaner. Cleaning should be done
twice each year or more frequently if needed due to environment. Excess dirt or poor ventilation can cause no cold water and compressor cycling
on the compressor overload protector.
5. Water Flow: Conrm proper water ow. If water ow is slow, inspect lter or inline strainer for restriction. Replace lter cartridge if required.
Disassemble inline strainer and clean if required.
6. Lubrication: Motors are lifetime lubricated.
7. Actuation of Quick Connect Water Fittings: Cooler is provided with lead-free
connectors which utilize o-ring water seal. To remove tubing from
the tting, relieve water pressure, push in on the gray collar before pulling
on the tubing. To insert tubing, push tube straight into tting until it reaches a
positive stop, approximately 3/4” (19mm).
Operation: Start-Up
1. Turn on the building water supply and check all connections for leaks.
2. Rotate fan to insure proper clearance and free fan action.
3. Connect plug-end of International Power Cord Set (sold separately) into electrical outlet.
WARNING
• Exposed, electrically energized components. Use extreme caution.
4. Purge air from all water lines by depressing button or front push bar of cooler/fountain.
5. Recheck all water and drain connections with water owing through system.
6. After verifying that the water cooler is properly connected and operational, replace and reattach the cooler front panel by retightening
screws

1. Lower Front Panel and Upper Shroud: To access the refrigeration system and plumbing connections, remove four (4) screws from bottom of cooler
to remove the lower front 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.
2. Bubbler: To remove the bubbler, rst disconnect the electrical supply. The underside of the bubbler
can be reached through the access panel on the underside of the upper shroud. 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 (see above).
When installing replacement bubbler and pedestal, tighten nut only to hold parts snug in position.
Do Not Overtighten. After servicing, replace the lower front panel and four (4) screws.
3. Switches Behind the Push Bar: The regulator in an EZ cooler is always held fully open by the use of
a single regulator nut. Water is not dispensed until the pushbar is depressed to activate a switch
which then opens a solenoid valve. When installing the regulator nut, the regulator spring must be
depressed while turning the nut. To remove sidebars, from the inside
compress the ared tabs and pull out careful. To reinstall side pushbars, the front of the pushbar
is inserted rst. While keeping the switch depressed, snap the rear of the pushbar into position.
Service: Inspection/Replacement
• Inspect Cooler twice each year for proper operation and performance.
• Inspection of the unit will require disconnecting electrical supply, removal of panels, etc. and reassembly and return to service practices.
