23G-Series RO System
3024270 Rev G 25 14Oct13
3.2 Initial Start-Up
CAUTION:
When the 23G RO machine is first installed or membrane elements are changed,
the RO unit must be rinsed to drain under normal pressures for a minimum of
one (1) hour before exposing membranes to Minncare
®
and a minimum of six (6)
hours before exposing membranes to formaldehyde or irreversible damage may
occur.
1. Open the feed line valve. At least 20 psi (1.4 bar) dynamic feed line
pressure is required.
3 Open the machine concentrate valve one or two turns. The
machine concentrate valve is located below the machine control
panel on the left.
4 Open the permeate CIP connection to flush the machine. The CIP
fitting requires a 1.0-inch MPT threaded fitting.
5 Close the permeate outlet valve.
5. Secure the end of the hose attached to the CIP fitting to a suitable
drain.
6. Verify that the concentrate outlet valve is open.
7. Verify that the concentrate CIP valve is closed.
8. De-energize the high voltage power to the pump motor starter.
Energize only the 115/230 volt control circuit by pressing the ON
key on the ECM-100 controller and then within 10 seconds, press
the CIP key. The machine must be in HAND mode in order to start
the machine alarms with the CIP key. Using the CIP key in this way
will bypass many of the alarms. Let the water flow through the
machine for at least five minutes under line pressure to purge air
from the system.
NOTE:
The high pressure pump should not be operated during this time. If a buffer
system is being used, it should be set to regulate feedwater pH at 6.5 or less.
The control range for buffer pump operation is from 1.8 to 8.0 less than the
high pH alarm setting. The buffer pump will turn on at 0.8 units less than the
high pH setting and turn off at 1.8 units less than the high pH alarm setting.
NOTE:
When the control circuit is de-energized, there should be no flow from the
concentrate outlet. The solenoid activated inlet valve should be closed when
de-energized. See Troubleshooting Guide (Section 7.0) if water continues to
flow after shutdown.
