General Information
Water Supply Requirements
Use only 1/4” (6 mm) copper tubing for
water line. Do Not install copper tubing in
area where temperatures drop below
35Þ F (1.7Þ C). Before attaching copper
tubing to the unit, flush at least 2 quarts
(1.9 L) of water through the copper tubing
and into a bucket to remove any particles
in the water line.
• Viking Range Corporation is not
responsible for property damage due to
improper installation or water
connection.
• Connect 1/4” (6mm) flexible copper tubing
to household plumbing in compliance with
local codes and ordinances.
• Length of copper tubing must reach from
water supply connection to the unit
connection with an additional length to
facilitate moving the unit out of enclosure
for cleaning or service. Tubing should be
soft instead of rigid and ends should be
free of burrs.
• Copper tubing route must be above 35Þ F
(1.7Þ C) to prevent water line from
freezing.
• Do not use plastic water lines from the
household plumbing to the water inlet
valve connection on the refrigeration
unit.
• Do not use the self-piercing feature of a
saddle valve. The hole made by the
piercing lance is too small for the water
flow rate required by the ice maker.
• If saddle valve is not used, place a
separate shut-off valve in an easily
accessible location between water supply
and the unit. Do not locate shut-off valve
behind the unit.
• The installation of Viking units with a
reverse osmosis system is acceptable
as long as the water pressure remains
within the allowable PSI as stated below.
It is important to note that with many
reverse osmosis systems, the pressure
starts off high, but then it decreases as the
water level of the reverse osmosis storage
area drops. This must be considered when
checking the water pressure coming into
the unit.
• Connect a vertical or horizontal 1/2” (1.2
cm) to 1 1/4” (3.2 cm) COLD water line
near water area.
• Run water line through the floor, back, or
side wall. Tubing should lay flat on floor
underneath the unit. Clamp tubing to wall
or floor.
• Water pressure must be greater than 20 psi
and less than 120 psi on non-dispensers
and greater than 35 psi and less than 120
psi on dispensers.
WARNING
To avoid serious illness or death, do not use unit
where water is microbiologically unsafe or of
unknown quality without adequate disinfection
before or after the system. Systems certified for cyst
reduction may be used on disinfected water that
may contain filterable cysts. The contaminants or
other substances removed or reduced by this water
treatment system are not necessarily in you water.
