Installation of the Valve Block
Please refer to the valve block schematics for your specific unit in the Wiring Diagram Section
for clarification of the below instructions. For High-Resolution systems, please refer to the
schematics that were included in the documentation package.
Securely fasten the valve block in place. The valve block can either be installed inside or
outside of the duct, however installing in-duct reduces the quantity of holes which must be
drilled through the duct.
The valves have threaded connections with a ½” G thread. Connect the high-pressure supply
line from the pump to the valve block inlet. It is recommended to use a 2 foot flexible hose
connection between the pump supply line and soft charge valve block. This flexible line
prevents the transmission of vibrations through piping. If the pump is only a short distance
away it is recommended to use high pressure flexible hose for the entire run.
Vibrations can be transmitted from air-handlers, the HP pump modules, or other mechanical
room equipment, it is strongly recommended to use a 2 ft (0.6 m) length of flexible piping at
the valve blocks, and HP pump module to protect the equipment from damage.
Install drain piping on the valve block. When the manifolds are not in use, they are drained to
prevent stagnant water, which can lead to microbial growth. The volume of water drained is
equal to the volume of the manifolds and their supply lines. The drain line can be solid pipe or
flexible hose for convenience. It must flow to an open-air funnel or nearby floor drain. The
water can also be reclaimed and returned to the RO system for processing.
The drain line must flow to an open-air funnel. Solid connection to a drain can result in
backflow, failure to drain, and dripping nozzles.
