WATER SUPPLY REQUIREMENTS
Water Pressure
A cold water supply with water pressure be-
tween 30 and 120 psi (207-827 kPa) is re-
quired to operate the water dispenser and ice
maker.
Reverse Osmosis Water Supply
IMPORTANT: The pressure of the water sup-
ply coming out of a reverse osmosis system
going to the water inlet valve of the refrig-
erator needs to be between 30 and 120 psi
(207-827 kPa).
If a reverse osmosis water filtration system is
connected to your cold water supply, the wa-
ter pressure to the reverse osmosis system
needs to be a minimum of 40 psi.
INSTALLATION INFORMATION
If the water pressure to the reverse osmosis
system is less than 40 to 60 psi (276-414 kPa):
Check to see whether the sediment filter
in the reverse osmosis system is blocked.
Replace the filter if necessary.
Allow the storage tank on the reverse os-
mosis system to refill after heavy usage.
If the refrigerator has a water filter, it may
further reduce the water pressure when
used in conjunction with a reverse osmosis
system. Remove the water filter.
