Noisy Operation

Check to make sure the fan blade is rotating freely.

Make sure the water cooler is correctly mounted to the wall. Absence of the two lower 
mounting bolts may cause excess noise and vibration.
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.

Restricted Or No Water Flow

Ensure water supply service stop valve is fully open.

Verify minimum 200 kPa supply line flow pressure.

Check for twists or kinks in bubbler tubing.

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 replaced if needed.
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.
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

Compressor Cycling on 
Overload Protector

A dirty condenser or a blocked fan will cause a high head pressure and frequent 
cycling of the overload protector.
Check the incoming voltage to make sure it is within 10% of the serial nameplate 
rating.
A restriction or moisture in the system will also cause intermittent cycling. A certified 
refrigeration mechanic should be contacted in this situation.
Change the overload or relay if defective.

Cleaning & Maintenance 

1.  Motors have lifetime lubrication and do not require scheduled maintenance.
2.  Excess dirt or poor ventilation will cause the compressor overload protector to turn the compressor off and it will cycle 

on and off with no cold water coming out of bubbler. Periodically clean with vacuum cleaner, air hose or brush the 
condenser fins and cabinet ventilation louvers. In environments where dirt and dust is more prevalent, clean more 
frequently.

3.  Periodically remove access panels and clean out in-line strainer.
4.  Do NOT use harsh chemicals, abrasive or petroleum based cleaners. Use of these will void RBA warranty.
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
