damage.
If a reverse osmosis water filtration system is
connected to your cold water supply, the water
pressure to the reverse osmosis system needs to
be a minimum of 40 to 60 psi (2.8 kgf/cm _ ~ 4.2
kgf/cm 2, less than 2.0~3.0 sec. to fill a cup of 7 oz
capacity).
..-_ CAUTION -.
Wear eye protection during installation /
to prevent injury.
J
If the water pressure from the reverse osmosis
system is less than 21 psi or 1.5 kgf/cm 2 (takes

(2.4 m). Be sure there is sufficient extra
tubing (about 8 feet [2.4 m] coiled into 3
turns of about 10 in. [25 cm] diameter)
to allow the refrigerator to move out
from the wan after installation.
