WATER COOLERS

6. Restricted Or No Water Flow
a. Ensure Water Supply Service Stop Valve is fully open.
b. Verify minimum 20 PSIG (168 kPa) 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.
CLEANING & MAINTENANCE GUIDE:
4. In the unwanted event when freezing has occurred, disconnect the electrical power. Allow the
ambient temperature to rise gradually to the minimum ambient temperature of 41°F (5°C) and
maintain this condition for at least two hours, check for leaks or cracks on the refrigeration or water
lines. Restore electrical power if no damage is found.
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.
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. Remove and clean.
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 Panel and clean out In-Line Strainer.
5. For cleaning, DO NOT use water jet, harsh chemicals, abrasive or petroleum based cleaners. Use of
these will void the Murdock Mfg. warranty.
6. 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 may scratch
easily and should only be cleaned using a clean, soft cloth and mild soap with water or a mild glass
cleaner.
