23G-Series RO System
3024270 Rev G 18 14Oct13
2.0 INSTALLATION
2.1 Machine Location
At least 45 inches (114 cm) of space should be allowed above the
membrane element housings for easy removal and loading of membrane
elements. Provide adequate workspace on sides and front for easy
access.
NOTE:
If necessary, housings may be detached from the frame for membrane
element removal due to space restrictions around the machine.
2.2 Plumbing
2.2.1 Inlet Plumbing
The feedwater source should be plumbed to the 1-inch FNPT inlet
point on the 23G machine. If the inlet pressure is in excess of 60
psi (4.1 bar) or fluctuates by more than 5 psi (0.3 bar), a pressure
regulator should be installed ahead of the connection. A low
pressure sensor is installed on every 23G machine to protect
against low inlet pressure. The 23G should not be installed where
the feedwater dynamic inlet pressure is less than 20 psi (1.4 bar). If
inlet pressure is less than 20 psi (1.4 bar), a booster pump must be
installed ahead of the connection.
2.2.2 Valves for Clean-In-Place (CIP)
All 23G units have separate CIP connections. Valves should be
installed on both the main and inlet cleaning connections of the inlet
stream. The permeate outlet and concentrate outlet plumbing
streams include factory installed manual shutoff valves.
CAUTION:
Do not operate the machine with all concentrate and permeate
connections closed. Severe damage to the unit may result.
2.2.3 Concentrate Outlet Connection
Connect a 1.0-inch hose or pipe to the concentrate outlet and run to
an open drain. To avoid drainage to the machine during non-
operation, the concentrate outlet plumbing should be placed at a
height which is at least equal to the height of the machine. A siphon
break may also be installed in the concentrate line for added
protection. The concentrate outlet hose or pipe can be any length,
and the diameter should match the outlet of the machine.
