PRECAUTIONS(SAFETY WARNINGS)
■ 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.
■ Ordering a new filter
To purchase a new water filter (part type: HAFEX/EXP), contact a local Samsung service centre.
■ To mount the water filter into place
1. Attach the lock clips (x2) to appropriate positions
under the sink, for instance.
Then, fix the lock clips firmly using screws.
2. Insert the water filter into the upper and lower
clips in the correct direction.
Make sure to check the vertical direction of the
water filter.
NOTE
If the filter is installed horizontally, water may remain in
the filter. Therefore, vertical installation is recommended.
CAUTION
Do not mount the water filter on any part of the
refrigerator. This may damage the refrigerator.
