INSTALL A REMOTE DRAIN POINT
AND AIR GAP (Remote Location)
You can also run the drain tubing to an existing drain in
the house. A floor drain, laundry tub, standpipe, sump,
etc. are suitable drain points. See Fig. 10. This type of
drain is the preferred over the p- trap drain adapter.
Check your local codes. Longer lengths of tubing (see
parts list in back of manual) may be needed.
Always be sure to provide an air gap between the end of
the hose and the drain point. This will prevent water from
backing up into the system. Airgaps are required code in
most areas.
To install a remote drain point, complete the
following steps:
1. Locate the 1/4” red tubing on the Reverse Osmosis
filter assembly. See Fig. 9.
2. Determine if this length is long enough to reach the
drain point.
3. If not, disconnect the 1/4” red tubing and replace with
an adequate length of tubing to reach the drain point.
Refer to Step 5 later in the manual on how to discon-
nect and connect tubing.
Note: A flow control insert is located in the red
tube. Refer to Fig 27. This insert must be saved
and placed in the new length of tubing.
4. Run the tubing to the drain point and secure at the
end with a bracket (purchased locally). See Fig. 10.
Provide a 1-1/2” air gap between the end of the tube
and the drain. See Fig. 10.
