Activated Carbon Filter
START-UP PROCEDURES (AUTOMATIC or MANUAL)
The Carbon Filter is shipped with DRY
activated Carbon media that MUST BE
HYDRATED
with water for 24 hours (12
hours minimum) before placing the unit
into service. Failure to properly HYDRATE
the activated Carbon media and perform
the following backwashing procedures may
allow Carbon fines to enter into the RO
system causing premature fouling of the
RO membranes.
DAMAGE TO MEMBRANES DUE TO
FOULING OR SCALING IS NOT COVERED
UNDER WARRANTY FOR REPLACEMENT.
If the Carbon filter has been shipped
preloaded with activated Carbon media,
install the controller valve head per the
manufacturer’s instruction manual and
proceed to step #1.
If the Carbon filter has been shipped with
loose activated Carbon media, load the
activated Carbon media on site into the
filter vessels per the manufacturer’s
instruction manual, install the controller
valve head and proceed to step #1.
NOTE:
FILL the filter vessel approximately
1/3 full with clean water before loading the
under gravel or filter media to avoid
possible breakage of the lower distributor.
1. Connect the feed water, backwash drain
and service lines to the filter’s controller
unit per the manufacturer’s instruction
manual included with the unit. Allow a 6-
8” air gap on the
drain line connection to the main
drain.
2. Connect the proper electrical power
connections for automatic units, per the
manufacturer’s instruction manual
included with the unit.
3. Direct the service line from the Carbon
filter to drain during the initial startup
backwashing procedures.
DO NOT ALLOW SERVICE WATER
FROM THE NEW CARBON FILTER
TO SUPPLY THE RO UNIT UNTIL
THE CARBON FILTER BACKWASH
PROCEDURES ARE COMPLETE.
4. Place the controller valve into the
backwash position and supply feed
water slowly until all air has vented out of
the Carbon tank. After the air has been
vented off and a steady flow of water is
observed to the drain, you may open the
feed water supply fully.
5. Allow the unit to backwash and sample
the water with a clean WHITE cup. You
may observe that the water is partially
black with some Carbon fines settling to
the bottom of the cup. Continue
backwashing until the water becomes
clear as sampled with the WHITE cup.
This may take 30 minutes or longer
depending on the amount of Carbon
media
