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

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sufcientforthe
voltage in use.
5. Check to be sure the outlet provides the voltage
requiredbythecooler.

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nd,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lling.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ll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.
