INSTALLATION AND CONNECTION PROCEDURES

5.
CAUTION:
Hold the membrane firmly to prevent it
from rotating when the elbow is installed
CAUTION:
When tightened, rotate the membrane
so that the elbow is pointed toward the drain
connection (See Figure 1). There must be sufficient
space to connect the tubing and to route tubing to
the drain without any kinks or tight bends.
Connect the Flow Control Elbow (Item 11) and 1/4”
tubing connector (Item 12) to the threaded drain
connector on the top of the Membrane (Item 23).

CAUTION:
Verify that the Flow Control Assembly
(Item 13) matches the membrane recovery rate and
output (See Figure 2 and Table 3):
CAUTION:
The inner diameter of the tubing is
critical to the performance of the flow control. Do not
use standard 1/4” tubing for the flow control.
Connect the flow control tubing to the flow elbow.
Insert the tube until it is fully seated in the connector.
Tighten the nut on the elbow.

250 GPD - Yellow Tubing 1/16 in. I.D. x27 ft., P/N 40600043
7.
CAUTION:
Do not alter the length of the flow
control tubing. To do so will change the system
recovery rating.
Route flow control tubing to the drain connection.
Draw excess tubing into a loop and secure the loop.
8.
CAUTION:
Approved air gap is required. See local
plumbing codes.
Connect the flow control tubing to the drain/air gap.
WARNING: USE FDA APPROVED SILICONE
LUBRICANT ON “O” RINGS. DO NOT USE
PETROLEUM-BASED LUBRICANTS.
9.
CAUTION:
Confirm that the “O” ring (Item 15) is in
place and lubricated.
CAUTION:
Tighten the sump by hand only. Do
not use tools as they may over-tighten and
damage the sump. Take care not to cut or pinch
the “O” Ring (Item 20).
Install the sump into the Reverse Osmosis
Manifold Head (Item 16).
10.
CAUTION:
The system will not shut down if the
solenoid is incorrectly installed. See Figure 3 for the
correct flow path.
Connect the 3/4” Nipple (Item 2) to the Solenoid
(Item 1) and connect the solenoid to the System
Inlet Port.

CAUTION:
Verify source water pressure before
connecting system. A Pressure Regulator is
required if pressure exceeds 862 kPa (125 psig).
A Booster pump may be required if pressure is
below 207 kPa (30 psig).
11. Connect source water line to the solenoid. Connect
product water line to the Outlet Port.
