Ice Maker Installations
Consult local plumbing codes before installing an
ice maker. The codes in some areas require the use of
a permanent shutoff valve instead of a saddle valve on
the water supply line. Codes may also place restrictions
on the use of compression fi ttings.
19.1.2 Checking Electrical Supply
The electrical outlet for the refrigerator-freezer
must provide the correct electrical supply. Be sure to

read the electrical ratings on the appliance. Check
these against the electrical supply provided at the wall
outlet. Modern household refrigerators and freezers
may need more current than older, simpler refrigera-
tors and freezers.
There should be a separate circuit from the ser-
vice panel to the refrigerator-freezer outlet. Avoid
using an extension cord between the refrigerator
power cord and the wall outlet or the resulting volt-
age may be too low. Voltage at the refrigerator outlet
can be easily checked with a voltmeter or multimeter,
