THE BASIC REVERSE OSMOSIS SYSTEM 13
Rev B
Recommended Placement Positions
The Merlin assembly should be positioned in one of two ways.
The first position is with the unit standing upright using the support leg
with the sumps horizontal. The tubing is directed to provide the best fit.
The second position, sets the unit on end so the manifold is horizontal
and the sumps are pointing up. The tubing is directed upward and the
locking bar is down to lock the tubing connections.
See illustrations at left.
The table below shows the coding system for the fitting connections.
Each fitting has a unique “keyed” socket on the manifold. Each fitting
also has a graphic symbol molded into the elbow with a corresponding
symbol on the manifold.

WARNING: Be sure to lubricate the O-rings on the fitting elbows
prior to inserting into manifold.
WARNING: Do not turn the incoming water valve on until the
locking bar is in place.
NOTE: If the installation is not using the optional flush tank, the top
connection will not have tubing. Instead a plug will be inserted into
the fitting. Do not remove plug unless you are attaching the tubing
and the flush tank.
