4- 13
Routine Maintenance
4.
Turn the RO on for five minutes and establish a pre-cleaning % rejection, TDS
and pH record on the cleaning disinfect log sheet.
5.
Prepare the cleaning solution by adding the amount of cleaner as specified on
the labeling to two gallons of pretreated or RO product water.
CAUTION:
Water to be used must be chlorine free or damage to the RO membranes may
result.
6.
Turn the RO power switch off and close the product valve.
WARNING:
Label machine with appropriate warning signs such as "Do Not Use / Contains
Cleaner" to prevent use of the RO until it is properly rinsed.
7.
Connect the product line to the white fitting on the disinfect/cleaning tank.
Open the product valve.
8.
Connect the feed line (green QD) from the pre-filter outlet to the green fitting on
the disinfect tank.
9.
Connect the drain line (red QD) extension and connect the female portion to the
red fitting on the disinfect tank.
CAUTION:
By connecting all the lines to the disinfect/cleaning tank, the system is set-up for
recirculation. Never leave the unit unattended in the recirculation mode.
4.3.1.2 Cleaner Recirculation and Dwell Time
1.
Turn the Dialyze/Flush valve to the Flush position and open the product valve.
The Flush mode will allow the flow of cleaner only to the rejection side of the
RO membrane to flush surface particulates away. Very little or no product
water will be made in flush mode.
2.
Turn the RO power switch ON. Let the RO operate for 5 to 10 minutes in the
flush mode. Pump pressure during this step should read approximately 40 – 80
PSI.
CAUTION:
Some pump noise (chattering) is normal in the flush position. Excessive pump
noise (chattering) can be damaging to the pump. The RO is in “flush” from the
full open (flush) position to just before the fully closed (dialyze) position. Adjust
it by partly closing the flush valve to reduce chattering of the pump.
CAUTION:
DO NOT ALLOW PUMP TO RUN DRY
. Damage will occur if pump is run
dry.
