1.
ALWAYS UNPLUG THE SYSTEM BEFORE
WORKING ON IT
.
The water coolers described
in this manual operate on either 110 volts, 60 hertz
single phase, or on 220/240 volts, 50/60 hertz single
phase. Every effort should be made to avoid electric
shock.
2.
ALWAYS SHUT OFF THE WATER FLOW AT THE
WATER SUPPLY LINE BEFORE WORKING ON
SYSTEM.
3. When using a volt/ohm meter in the ohms mode, be
sure the cooler is unplugged.
4. When using a volt/ohm meter in the AC volts mode,
be sure the meter is set on a level sufficient for the
voltage in use.
5. Check to be sure the outlet provides the voltage
required by the cooler.

TROUBLE SHOOTING
GUIDE
(Unit Problems)
Some problems have simple solutions. This section describes a couple of them.
1.
NON-WORKING SYSTEM: CHECKING THE VOLTAGE
The easiest solution to a non-working system may be to plug the system’s service cord into an electrical outlet.
Although most solutions are not usually this simple to find, do not be lulled into forgetting to check this possible
cause of trouble.
Check
•
Is the service plugged in?
•
Is the switch controlling the outlet in the ON position?
Test
•
Plug in the cooler.
•
Make sure any switch controlling the outlet is in the ON position. Remove the service cord from the wall
outlet and plug in a radio or similar device. If the radio works, the outlet is good.
Repair/Solution
Incorrect voltage through the outlet may need to be corrected by the local utility company. Contacting the utility
is the responsibility of the customer.
2.
NON-WORKING SYSTEM: CHECKING THE CUSTOMER’S NEEDS WITH THE SYS
-
TEM’S CAPACITY
Under normal conditions, most coolers will produce 1.0 gallon of cold water (<10°C) per hour and a little more
than 1.5 gallons of hot water (80°C-90°C) per hour.
Check
A.
The temperature. If the temperature of the room containing the cooler or the temperature of the water
in the cooler is below 32°F, the cooler will not be able to provide as much cold water within the standard
amount of time.
B.
Amount of hot/cold water required in an average hour.
Find out how many persons use the cooler
each hour and what size cups they are filling. Calculate the total amount of water required in an
average hour.
C. Special customer needs for large amounts of water during certain periods of the day. For example,
does the customer need 9 liters of cold water at 12:45 each afternoon to fill pitchers for meeting rooms?
Does the customer need 18 liters of hot water early each day when coffee or tea is prepared?
Repair/Solution
If customer’s water needs are exceeding the cooler’s capabilities, consider adding another cooler.
