SHUTDOWN
1.
Cut off feed water supply and/or unplug unit.
2.
If the unit is to be shut down for more than 1 week, a membrane preservative should
be used (AMI Model No. AM-88). The preservative can be injected into the system
by using a tank and recirculation pump. Close "Control" valve after injection to hold the
preservative in the pressure vessel.
3.
When the system is restarted after an extended shutdown, follow initial system start up
procedures.
SYSTEM MONITORING AND RECORD KEEPING
The system should be monitored and all pertinent data recorded on a daily basis. Data is
needed to determine operating efficiency and for performing system maintenance. The latter
includes cleaning of the membranes, adjusting the operating conditions, replacement of
membranes, and antiscalant use.
