1. Temperature Control: Factory set for 50ºF ± 5º (10ºC ± 5º) water under normal conditions. To adjust water temperature, turn screw
clockwise for colder, counter clockwise for warmer.
2. Water Stream Height: Stream height is factory set at 35 psig (0.24 MPa). If supply pressure varies greatly from this, adjust screw using the
access hole in the pushbutton (insert athead screwdriver). Clockwise adjustment will raise stream and counter-clockwise adjustment will
lower stream height. For best adjustment, stream should hit basin approximately 6.5” (165mm) from bubbler.
NOTE: If water does not ow or ows sporadically after a refrigeration cycle, turn cold control counterclockwise 1/4 turn.
3. Water coming out of Bubbler continuously: Check the solenoid valve and cooler fountain push button. For cooler with push button, see
Cooler Manual-Water Valve Mechanism-Adjustment Procedure.
Service: Inspection/Cleaning
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
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).
Make sure not to damage the bubbler screen while cleaning.
3. Condenser Fan Motor: Conrm condenser fan turns freely. If the condenser fan does not spin freely, have an authorized service person
replace.
4. Ventilation: Cabinet louvers and condenser ns should be periodically cleaned with a brush, air hose or vacuum cleaner. Cleaning should be
one 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 inline strainer for restriction.
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).
• Inspect Bottle Filler and 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.
