See the Flow Control and Screen section.
If the Reverse Osmosis Filtration system is
connected to your icemaker
YOU MUST
turn off
the icemaker by raising the feeler arm before
servicing the filter, changing the filters, or purging
the filtration system. Four hours after servicing
your unit, lower the feeler arm to resume
icemaking.
When replacing cartridges you may lift the
Reverse Osmosis assembly from the mounting
washers and lay it on the floor. You can also
remove the Reverse Osmosis housing by pulling
it out of the mounting clamps.
Be sure you clean your hands with anti-bacterial
soap before handling inner parts of the system.
Be sure the water supply valve to the Reverse
Osmosis system is turned off (turn clockwise)
and the RO
water faucet is open. Allow the
system to drain completely (this takes several
minutes).
Pull the Reverse Osmosis system out away
from cabinet. Leave tubing connected. Place a
dry towel under the Reverse Osmosis unit.
Using pliers remove the lock washer, pull the
u-pin and remove the Reverse Osmosis
housing inlet cover. Save the lock washer for
final assembly.
CAUTION:Failure to close the water supply valve
will cause water to spray or run when sumps are
removed.
Remove the lock washer, pull the u-pin and
remove the inlet cover from the housing.
Use pliers to pull the cartridge from the
housing and discard the cartridge.
Sanitize the system. Go to the
Sanitizing the
Reverse Osmosis System
section and follow
steps 4 through 11.
Install new flow control and screen. Go to the
Flow Control and Screen
section for directions.
Pull the u-pin and remove the inlet cover
from the housing.
Install the new Reverse Osmosis cartridge.
NOTE:
The Reverse Osmosis cartridge o-ring
end is notched and may need to be rotated
during reinstallation for proper fit.
Replace the inlet cover. Lightly lubricate the
o-ring seal with only clean silicone grease.
Insert the u-pin and install the lock washer.
Turn on the water supply. Check for leaks.
Purge the Reverse Osmosis system. Go to the
Purging the Reverse Osmosis System
section.
CAUTION:The Reverse Osmosis cartridge
contains a food grade preservative that should
be purged from the system before first use or
whenever the Reverse Osmosis cartridge is
replaced. The preservative will give product
water an unpleasant taste
and odor. After the
tank has filled (takes about four hours), open the
system faucet until the bladder is empty. After
four of these drainings, the system is ready to
make product water for your use
.
