WARNING:
Do not attempt to mount/hang the system. Do not
try to drill mounting holes anywhere on the
E
system.
If putting above ground/cabinet level, a sturdy,
N
permanent shelf is recommended.
G
Recommended placement positions
L
The RO assembly should be positioned in one of two ways.
The first position is with the unit standing upright using the
I
support leg with the sumps horizontal. The tubing is directed to
S
provide the best fit.
The second position, sets the unit on end so the sumps are
H
pointing up. The tubing is directed upward and the locking bar
is down to lock the tubing connections. See Figure 9: System
Positions.
NOTE: Ensure that the support leg is installed on the sumps.
Connection lubrication
Connections with O-rings must be properly lubricated. The
following instructions describe the method and locations for
lubrication.
Six packets of silicone lube are supplied. One packet should
be completely used to lubricate the O-ring contact surfaces in
the 3 manifold ports and 2 RO membrane locations (Figure 10).
Follow figure 11 and lubricate the filter seat and the flat
surface below the threads for the 3 sump locations. Use a
complete packet of silicone for each sump location.
NOTE: To properly lubricate the O-ring contact area, a film of
clean silicone grease is applied. The film should cover
all of the surface area that the O-ring will slide over and
seal with. Do not use grease containing petroleum
products.
