OPEN WATER SUPPLY
With the plumbing, drain line and overflow
connections completed, slowly open the water
supply, allowing the lines to pressurize.
NOTE: The optional bypass should still be in bypass
mode as shown.

START-UP RINSING PROCEDURE
(BYPASS VALVE IS OPTIONAL)
Outlet Inlet
ADVANCE THE CONTROL VALVE
With the transformer unplugged, manually advance
the control valve by depressing the drive gear and
rotating the main system gear to the purge position
(see Step 4).
2
RUN THE WATER
After the 20-minute purge cycle, manually advance
the main gear to the backwash cycle and allow to
run for a minimum of 10 minutes.
After 10 minutes during the backwash cycle, open
both the inlet and outlet valves on the bypass to the
fully opened position.
NOTE: When advancing the main gear manually
while under water pressure, it is normal for the gear
to encounter resistance as the valve chambers
depressurize. If resistance occurs, pause five
seconds to allow the valve to depressurize
before advancing to the next step.
Advance the gear in the counterclockwise direction
only. Damage will occur if advanced in the opposite
direction.

FILL BRINE TANK
After the ten-minute backwash cycle, manually
advance the control valve to the brine refill position
for ten minutes, allowing water to flow into the
brine storage tank.
Once water begins to flow into the tank, fill the
brine tank with a minimum of 80 lbs. of salt pellets.
5
PURGE THE SYSTEM
Slowly open the inlet valve (only) on the bypass
valve to the half-opened position, allowing the
system to pressurize. It is normal to hear air
blowing to the drain during this procedure.
Once the air clears and water begins to run to
the drain, open the inlet valve (only) to the full open
position and allow the water to run to the drain in
purge for a minimum of 20 minutes.
