Service: Adjustments

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 Flathead screwdriver). Clockwise adjustment will raise stream and counter-clockwise adjustment willpower stream height. For best adjustment, stream should hit basin approximately 6.5” (165mm) from bubbler.
   NOTE: If water does not flow or flows sporadically after a refrigeration cycle, turn cold control counterclockwise 1/4 turn.

3. Water coming out of Bubbler continuously: Check the solenoid valve and the electric eye sensor. For cooler with press bars, see Cooler Manual Water Valve Mechanism-Adjustment Procedure.

4. Cooler 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. Turn this screw clockwise to increase range and counterclockwise to decrease range.
   CAUTION
   Complete range of sensor (24-46 inches/610-1168mm) is only one turn of the adjusting screw.

5. Sensor Control: If sensor fails to operate valve mechanism or operates erratically, check the following:
   – Ensure there are no obstructions within a 40 inch (1016mm) radius in front of cooler.
   – Check wire connections at the solenoid valve and sensor.
   CAUTION
   Make sure unit is unplugged before checking any wiring.
   – 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.

Service: Inspection/Cleaning

• 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.

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 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.

2. Bubbler: Mineral deposits on the orifice can cause water flow to spurt or not regulate. Mineral deposits may be removed from the orifice with small round file not over 1/8” (3mm) diameter or small diameter wire.
   CAUTION
   DO NOT file or cut orifice material. Care must be taken not to damage the orifice(s)

3. Condenser Fan Motor: Confirm condenser fan turns freely. If the condenser fan does not spin freely, have an authorized service person replace.

4. Ventilation: Cabinet louvers and condenser fins 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: Confirm proper water flow. If water flow is slow, inspect filter or inline strainer for restriction. Replace filter cartridge if required. Disassemble inline strainer and clean if required.

6. Lubrication: Motors are lifetime lubricated.
