Connecting to Power
Before
connecting this unit to a power source, verify the required voltage by studying the model
nameplate affixed to your machine. Cool Boss models marked CB-12SL and CB-14 SL indicates 110
VAC operation; model numbers with an H
suffix
indicates 208 to 240 VAC operation (e.g. CB-16 SLH
for 220 VAC operation).
It is recommended that a separate electrical circuit servicing
only the Cool Boss be provided.
If your Cool Boss is equipped with a plug
not
compatible with your current power source, you must
contact a licensed, certified Electrician. The Electrician will install a separate 15 Amp circuit protected
by a fuse or circuit breaker with an appropriately grounded power receptacle in accordance with all
national and local electrical codes
.
Use an outlet that cannot be turned off by a switch
.
No Electrician is required to connect the Cool Boss with a 110 VAC power source as shipped from the
factory. Units operating at 110 VAC have the appropriate plug attached. Only units requiring 220 VAC
operation require an electrician to install the required 220 VAC plug.
⚠
DANGER All electrical work must be accomplished by a licensed, certified Electrician ,
in accordance with national and local electrical codes. If you do not use a licensed,
certified Electrician, you void your warranty and put everyone who uses the cooler
in danger of injury or, in rare cases, death.
To connect the Cooler to a 220 VAC power source:
Verify the Cool Boss is disconnected from the power source.
If it is connected, disconnect it. Do not begin to install a 220 VAC plug until you are
sure that power has been disconnected from the unit.
Verify the Cooler is configured for 220 VAC operation. Locate the Model/Serial Number plate near
the Cooler Display. The operating voltage is indicated on this data plate and should indicate 208 –
230 VAC operation. If this data plate indicates 110 VAC, then the unit cannot be run on 220 VAC.
Have a
licensed, certified Electrician
attach a 250 VAC NEMA 30A, 2-Pole, 3-Wire plug.
This Plug is not shipped with the Cool Boss. You must have the Electrician bring the correct plug.
The colors of the three exposed wires from the power cord are Brown, Blue, and Green/Yellow,
the European color code.
Important: To connect the three exposed wires to an appropriate Plug or to hard-wire them,
have your Electrician follow the electrical codes for the country and locality in which
you are using the unit.
For example, if you are using the unit for 220V in the United States, the color codes of the power
cord wiring on the Cooler correspond to:
Brown : Live
Blue
: Live
Green/Yellow : Ground
If you were using the unit in a European
country, the color codes on the wiring that
comes with the Cooler correspond to:
Brown
: Live
Blue : Neutral
Green/Yellow : Ground
