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 a
small round file not over 1/8” (3mm) diameter or small diameter wire.
DO NOT file or cut orifice material. Care must be taken not to damage the orifice(s).
3. 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.
4.
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.
5.
Lubrication: Motors are lifetime lubricated.
6.
Actuation of Quick Connect Water Fittings: Cooler is provided with lead-free connectors
which utilize o-ring water seal. To remove tubing from the fitting, relieve water pressure,
push in on the gray collar before pulling on the tubing. To insert tubing, push tube straight
into fitting until it reaches a positive stop, approximately 3/4” (19mm).

Service: Adjustments
1. Temperature Control
: Factory set for 50°F water (+/- 5°) (10°C ± 2.8°) under normal conditions. For colder water, adjust screw on cold control
clockwise (see Cooler Manual).
2.
Water Stream Height: Stream height is factory set at 35 PSI (2.4 bar). If supply pressure varies greatly from this, adjust screw located on the
right knee clearance area. 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 water does not flow or flows sporadically after a refrigeration cycle, turn cold control counterclockwise 1/4 turn.
3. Stream Regulator:
If orifice is clean, regulate flow as in “STARTUP” instructions above. If replacement is necessary, see parts list for correct
regulator part number.
4.
Water coming out of Bubbler continuously: Check the solenoid valve and the electric eye sensor.
5. 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.
6. 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.
- 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 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.
Service
•
Safety Glasses
• Protective gloves
For proper and safe servicing, please read these instructions completely.
DANGER
•
All Service and Maintenance must be performed by an authorized service person.
Service Technician must have specialized training before servicing systems containing flammable refrigerants.
Personnel who have not received certification for completing the Hydrocarbon Training Program and passed the examination, or received
equivalent training and certification, shall not service any system containing flammable refrigerants.
•
Disconnect electrical supply to the unit before any service work to reduce risk of electrocution.
•
Shut off water supply serving the unit before any service work to reduce risk of water damage.
CAUTION
• To prevent scratching the basin, place a towel or soft cloth over the entire basin when working above it.
• Do not puncture tubing.
•
No open flame or sparks during servicing or repair.
•
Repair and Disposal must be carried out by trained service personnel.
• Place in a well ventilated area to prevent accumulation of refrigerant.
•
Tools/Items required but not provided, for Servicing:
CAUTION
•
Hex drives
•
5/32” (4mm) Hex Key Flat blade Screwdriver
CAUTION
Complete range of sensor (24-46 inches/610-1168mm) is only one turn of the adjusting screw.
CAUTION
Make sure unit is unplugged before checking any wiring.
