Electrical Requirements & Safety
A 15 amp or 20 amp, 110-120 VAC, circuit which is
grounded and protected by a circuit breaker or fuse is
required.
We recommend using a dedicated circuit for each
appliance to prevent circuit overload and the chance of
interruption to the appliance.
The appliances are equipped with a three-prong
(grounding) polarized plug for protection against possible
shock hazards.
Comply with the National Electrical Code as well
as local codes and ordinances when installing the
receptacle.
WARNING!
Electrocution hazard.
Electrical grounding required.
•
Do not remove the round grounding
prong from the plug.
•
Do not use extension cords or
ungrounded (two-prong) adapters.
• Donotuseapowercordthatisfrayedor
damaged.
• Do not use a power strip.
Failure to follow these instructions may
result in fire, electrical shock or death.
General Remarks
IceMaker (if equipped)
The icemaker is located in the freezer compartment. It
must be connected to the water supply. The appliance
must be level for the icemaker to function properly.
Except for the CS 1640B which has an internal tank ice
maker
The water supply pressure requirements are different
based on whether or not the supplied Liebherr water filter
is installed. With the filter installed, the pressure must be
in the range of 40-90 psi (2.8-6.2 bar). Without the filter
installed the acceptable pressure range is 22-87 psi (1.5-
6 bar).
Use a braided style ice maker hose with 1/4" compression
end or a 1/4" OD copper line to connect the water supply
with the solenoid valve of the appliance. This is not sup-
plied with the appliance.
The supplied brass fitting
must be used to connect to the solenoid
as the plastic threads on the solenoid are
metric.
If you have hard water, we recommend you install a
water softener. Also, a filter must be installed if the water
contains solids such as sand.
All equipment and devices used to supply the water to
the appliance must comply with the current regulations
for your geographical area.
Safety Instructions and Warnings
• Donotattachthewatersourcewhiletheapplianceis
connected to an electrical outlet.
• Ashut-offvalve,mustbeinstalledbetweenthehose
line and the main water supply so that the water
supply can be stopped if necessary. Do not install
the shut-off valve behind the refrigeration unit, so the
water can be stopped without removing the appliance
from its niche.

ance is located.
