UTILITY TABLES
FUNCTION AND PURPOSE
This utility table is intended to hold non-perishable food
products or supplies. It is NOT to be used for the holding or
serving of food items that require temperature maintenance
for safe consumption.
CLEANING
1. Wipe all surfaces with a clean, damp cloth.
2. If soap or chemical cleaners are used to clean the metal
surfaces, be sure they are completely rinsed away with
a clean damp cloth or sponge. Chemical residue may
corrode the surface of the utility table.
Symptom
One well does not get as hot as all the others.
Elements burn out after a short time.
Drains leak.
Unit heats when thermostat dial is in off position.
Unit does not get hot enough.

TROUBLESHOOTING GUIDE

Thermostats could be out of calibration. To test, when the unit is cold, turn
the thermostat from the off position slowly to full on. You should hear a
"click" at about the second or third position. If the click is heard much later,
the thermostats are out of calibration and must be replaced. Knocking the
thermostats can cause them to be thrown out of calibration.
Check voltage. 208V units are not designed to operate on 240V. Check
the power supply. Operators often plug 120V 5-30 and 5-50 plugs into
208V or 240V receptacles.
Elements must always be covered with water. If the unit is used without
water, the elements will burn out prematurely.
Check for obstructions preventing the valve to close properly.
Plastic drain adapter is cracked where brass reducer or valve is screwed
into drain adapter. The drain parts should be hand tightened only. Teflon
tape should not be used when installing drain valves. Over-tightening the
drain parts will crack the plastic.
Thermostat is wired wrong. Wires should be on terminals 1 and 2.
Thermostat is damaged and must be replaced.
Too much water. 480 Watt units should only have 2 Quarts of water and
must be preheated with a cover for 1 hour.
Check to see the unit has the proper voltage. A unit requiring 120V supply
will not perform properly if the voltage supplied is low.
