STEP 15: IMPORTANT: Activated Carbon, Filter Ag and Birm must be soaked for at least 2 hours
prior to submitting it to full flow rate to prevent loss of media to drain.
Once the air is
purged, fully open the bypass
valve to the “Service” position (Figure 3, Page 4) and leave the
control valve in “Backwash” position for at least 10 minutes or until water flowing from the drain
line runs clear; whichever is longer.
STEP 16: Plug the power cord back into an un-switched electrical outlet.
Manually advance the contr
ol valve to the “Service” position (Figure 4a) by turning the Manual
Backwash Knob clockwise and reconnect the control valve to the electrical outlet. Check for
and resolve any leaks in the unit or connected plumbing.
STEP 17: Set the Timer Control (Figure 4a) by rotating the Skipper Wheel (Figure 4a) so the red pointer
is directly over day 1. Select the days when backwashing will occur by sliding the metal tabs in
or out. IN indicates no backwashing will occur on that day, OUT indicates that backwashing
will occur on that day.
Factory setting is to initiate backwash every third day.
IMPORTANT: Raw water quality determines the frequency of backwashing required. It is
recommended that the unit be backwashed NO LESS THAN every 6 days. If pressure drop
increases or contaminants are detected in the filtered water, backwashing frequency MUST be
increased. Filters with Calcite or Neutralizer media should be backwashed AT LEAST EVERY
OTHER DAY to prevent the media particles
from “cementing” together.
STEP 18: Set the current time of day by depressing the red Time Set Button (Figure 4a) and turning the
24 Hour Gear (Figure 4a) to the desired time (note AM and PM).
STEP 19: Time of Regeneration is factory set to 12:00 A.M. To adjust the time of regeneration:
a) Unplug control valve from electrical outlet.
b) Locate three screws (Figure 4b) behind the Manual Backwash Knob (Figure 4a) by
pushing the red Time Set Button (Figure 4a) and rotating the 24 Hour Gear (Figure
4a) until each screw appears in the cut out portion of the Manual Backwash Knob.
c) Loosen each screw slightly to release the pressure on the time plate of the 24 Hour
Gear
d) Continue depressing the red Time Set Button and rotate the 24 Hour Gear to
expose the Regeneration Time Pointer (Figure 4a) in the cut out portion of the Manual
Backwash Knob. Keep the Regeneration Time Pointer visible in the cut out while
rotating only the time plate until the desired time of regeneration (note AM and PM) is
aligned with the Regeneration Time Pointer.
e) Continue depressing the red Time Set Button and rotate the 24 Hour Gear along
with the Time Plate until each screw has been exposed in the cut out portion of the
Manual Backwash Knob and re-tightened. DO NOT OVERTIGHTEN. Make certain
that the backwashing filter DOES NOT regenerate at the same time with any other
water treatment equipment.
STEP 20: Turn on fuel/electrical supply to water heater.
RECOMMENDED: Retain the red distributor cap and blue media funnel for future replenishment of filter media.
NOTE: If the FBW filter is loaded with any self-sacrificing media like Calcite or Neutralizer, mark the
media level on the side of the tank by shining a bright light through the tank to see its level. Replenish
the media in the mineral tank when the level drops by more than three inches.
