Installing the Power Cord
Once you have verified that the power supply matches the electrical
requirements of the freezer, connect the unit to the power supply using the
power cord provided.
CAUTION!
If the plug on the power cord does not fit the outlet, or if the freezer’s
voltage rating does not match your electrical supply, do not plug the
freezer into the power supply. Contact your laboratory supervisor,
safety officer, or qualified service or electrical engineer.
#
NOTE:
Some freezers are supplied with more than one removable power cord.
Utilize the cord that matches your power outlet.
1.
Unwrap the power cord(s) provided. If you have more than one, select the
correct cord for your facility’s power outlet.
2.
Install the rectangular end of the cord into the power outlet at the back of
the freezer.
3.
Fasten the safety clip around the cord by tightening the screw located at the
top of the safety clip.
4.
Plug the other end of the cord into an appropriately rated power outlet.

Power Switch Operation
The
ON/OFF
circuit breaker power switch is located within the lockable panel
(a) at the bottom lefthand corner on models U360, U535 & U725, or (b) at the
top righthand side on models U101, C585 & C760. The panel can be removed
by turning the key (provided) one quarter turn to the right. The key can be
removed to prevent access.
Set the
ON/OFF
power switch to the
I
(ON)
position. The display illuminates
immediately.
#
NOTE:
The freezer’s compressor will not operate for approximately one minute
after connection of the power supply, because there is an automatic delay
device in the circuit. Temperature and alarm settings, however, can be
adjusted immediately.
