7. Water Drip Or Will Not Shut Off:
a. Remove Pushbutton Adjust flow regulator to the highest setting using a
flat head screwdriver and turning clockwise. Check if water drip continues, if it is no longer
dripping turn screwdriver counter-clockwise until you have desired flow rate. Assure that
retaining nut is tighten to valve assembly, 25 in-lb torque is required. If issue still continues after
adjusting flow and tightening retainer nut, replacement of the flow regulator cartridge will be
required.
4. Compressor Cycling On Overload Protector
a. A dirty condenser or a blocked fan will cause a high head pressure and frequent cycling of
the overload protector.
b. Check the incoming voltage to make sure it is within 10% of the serial nameplate rating.
c. A restriction or moisture in the system will also cause intermittent cycling. A certified
refrigeration mechanic should be contacted in this situation.
d. Change the overload or relay if defective.
3. Periodically remove access panels and clean out in-line strainer.
6. Restricted Or No Water Flow
a. Ensure water supply service stop valve is fully open.
b. Verify minimum 20 psig supply line flow pressure.
c. Check for twists or kinks in bubbler tubing.
d. Check the water inlet strainer. Sediment from the main supply can get trapped in the
screen along with installation materials such as pipe dope and flux. The screen should
be cleaned and checked on a regular basis and replace if needed.
NOTE: STRAINER SCREEN MUST BE IN PLACE FOR WATER TO FLOW.
e. The cartridge valve located in the water control assembly or bubbler can also become
clogged with foreign material. The cartridge valve can only be replaced and not repaired.
f. Check flow adjustment. See start up note #3.
g. The water cooler may also develop a freezing condition in which the water will become
frozen inside the evaporator coil. This indicates a refrigeration problem or thermostat
failure in which case the water cooler needs to be checked by a qualified technician.
5. Exterior panels can be cleaned using mild household detergents or warm, soapy water. Extra care must be
used cleaning chrome plated items and mirror finished stainless steel. They can scratch easily and should only
be cleaned using a clean, soft cloth and mild soap with water or a mild glass cleaner.
c. An incorrect refrigerant charge, restriction or defective compressor (not pumping) will also
cause the compressor to run without producing cold water. All these signs indicate a
problem within the refrigeration system and the water cooler must be checked by an
authorized service company.
5. Noisy Operation
a. Check to make sure the fan blade is rotating freely.
b. Make sure the water cooler is correctly mounted to the wall. Absence of the two lower
mounting bolts may cause excess noise and vibration.
c. Check the compressor mounting to make sure the pins and clips are not rattling. If the
compressor appears to be noisy internally, it must be replaced.
1. Motors have lifetime lubrication and do not require scheduled maintenance.
2. Excess dirt or poor ventilation will cause the compress` more frequently.
CLEANING & MAINTENANCE GUIDE:
4. Do NOT use harsh chemicals, abrasive or petroleum based cleaners. Use of these will void the Acorn warranty.
