Your Reverse Osmosis Drinking Water System can
be installed under a sink or in a remote location.
Typical remote sites are a laundry room or utility
room. Review the location options below and deter-
mine where you are going to install your system.
UNDER THE SINK LOCATION
The Reverse Osmosis Filter Assembly and
storage tank may be installed in a kitchen or
bathroom sink cabinet. See Fig. 4.
A suitable drain point is needed for drain water
from the Reverse Osmosis system.
REMOTE INTERIOR LOCATION
The Reverse Osmosis Filter Assembly and
storage tank may also be installed in a remote
interior location away from the Reverse
Osmosis Faucet. You will need a nearby water
source and drain point. See Fig. 5.
