GENERAL INFORMATION
The Norcold six cubic foot refrigerator will
be used in model ZE06582. The refrigerator
will operate on either 12-volts D.C .
or 120
volts A.C .
This dual voltage refrigerator
automatically switches from A.C. to D.C . or
D.C . to A .C .
The six cubic foot refrigerator cooling
system is basically the same as the seven and
one-half
cubic foot refrigerator with the
exception of the power required to operate the
swing motor compressor .
Refer to "Com-
pressor
Voltage
Check"
and
"Compressor
Amperage"" for specific values required .

SERVICING
COMPRESSOR VOLTAGE CHECK
The voltage is checked at the compressor
terminals with an A .C . voltmeter (Figure 1).

REFRIGERATOR
The information described in Maintenance Manual X-7525 under the heading
REFRIGERATOR (SEC. 24D) is applicable to models covered by this supplement
with the exception of the following:
24D-1
NOTE :
A standard (RMS) A .C. voltmeter
will read a high A.C. compressor voltage on
D.C . operation .
The reason being the
inverter does not produce a true sine wave
on D.C. operation .
The 120-volt A.C ., 60
cycles/second, will produce a true sine wave
which an A .C . voltmeter is designed to read .
If the voltage at the compressor is not
adequate
the
voltage
source
should
be
checked .
A.C . Operation
Using a standard (RMS) A.C . voltmeter the
voltmeter reading should be:
6 cubic foot model = 19 to 21 volts
7-1/2 cubic foot model = 22 to 24 volts
D.C . Operation
Using a standard (RMS) A.C. voltmeter the
voltmeter reading should be:
6 cubic foot model - 27 .2 to 29 .2 volts
7-1/2 cubic foot model - 31 .5 to 33 .5 volts
COMPRESSOR AMPERAGE
One method of determining whether or not
the proper amount of freon is in the cooling
