Installation
Reverse osmosis water filtration system
The water pressure of the water supply system to a reverse osmosis water filtration
system must be between 241 kPa and 827 kPa.
The water pressure of the reverse osmosis water filtration system to the refrigerator's
cold water line must be at least 276 kPa. If the water pressure is below the specified:
• Check if the sediment filter in the reverse osmosis system is blocked. Replace the filter
if necessary.
• Refill the water tank in the reverse osmosis system with water.
• If your 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.
For more information or servicing, contact a licensed plumbing professional.
NOTE
WATER FILTER MUST BE INSTALLED.
• Make sure to install a water filter.
• Failing to install a water filter may allow fine foreign materials (sand, lime) in the water
to continuously enter the water supply line and possible cause defects in the water
supply system.
