Placing Softener Into Operation - Pentair PRF 1035CS Service Manual

PLACING SOFTENER INTO OPERATION

After you have performed the previous initial power-up steps,
you will need to place the softener into operation. Follow these
steps carefully.
If the inlet water valve is opened too rapidly
or too far, media may be lost out of the tank
into the valve or the plumbing. In the 1/4 open
position, you should hear air slowly escaping
from the valve drain line.
NOTE: We recommend that you do not put salt into the
tank until after the control valve has been put into
operation. With no salt in the tank, it is much easier to
view water flow and motion in the tank.
NOTE: As you advance through each cycle there will be a
slight delay before you can advance to the next cycle.
The hourglass icon will light while the camshaft is
indexing.
Press and hold the Recharge key to start a recharge.
To Advance Recharge Cycles:
• Simultaneously press Time of Day and Recharge to
advance to the next cycle. An hourglass will display while
cam is advancing.
When Cam reaches the next cycle, Time Remaining will
be displayed.
• Repeat pressing Time of Day and Recharge to advance
through each cycle.
• To determine which cycle the controller is in during a
recharge, use Table 1. The time remaining is displayed on
the controller. Find the time remaining below your salt
setting. The cycle column will have the cycle number.
• Press and hold Time of Day and Recharge for 3 seconds to
advance through all remaining recharge cycles.
Hourglass will flash.
Camshaft will advance to service - may take 1 to
2 minutes.
• For cycle times see Table 1.
Before turning on the water supply check the following:
• All plumbing is installed and secured.
• The valve drain line is in place and the end is held
securely at the drain.
• There is no salt in the tank.
• The controller is on and has been programmed following
the three steps. The display should be showing the time of
day with the colon flashing.
• The inlet water is off and the bypass is not in bypass

The following steps will describe how to perform a quick
recharge to verify the system is working correctly.
1. Turn the incoming water on at a low flow position. Listen
to the water flow. Water is entering the media tank. Do not
open the valve completely because media may enter the
valve.
2. Start a recharge.
3. Open a service faucet. The salt tank will begin to fill with
water. Air will come out of the faucet. After all of the air has
left the media tank the water will run without air spurts.
When the salt tank has 3 to 4 inches (7.6 or 10.1 cm) of
water, turn off the faucet and advance to the next cycle.
4. Turn inlet water on full.
5. The brine prep cycle allows the water in the salt tank
to dissolve the salt. During this cycle inspect for leaks.
If any leaks are present they should be repaired before
proceeding. If there are no leaks, advance to the next cycle.
6. Backwash forces water through the media to the drain.
Inspect the water for air bubbles and small particles. When
the water is running clear, advance to the next cycle.
7. Brine draw and slow rinse run at the same time. The
discharge to drain will slow down. The water in the salt tank
will lower. If water is leaving the salt tank, advance to the
next cycle.
8. The repressurize cycle is short and allows internal system
pressures to stabilize. After 1-2 minutes advance to the
next cycle.
9. Fast rinse is a full pressure rinse of the media in the tank.
The discharge to drain should be high. Advance to the next
cycle.
10. Backwash 2 is a second backwashing of the media tank.
Discharge to drain will be slow. Advance to the next cycle.
11. Fast rinse 2 is the last cycle in the recharge process. Flow
to drain will be high. This cycle is 1 min long. Allow this
cycle to complete and advance to Service.
The controller will start the first time with a recharge
scheduled to start at the normal time of recharge. The media in
the tank will function properly until that first recharge.
Fill the salt tank with softener salt. The display should be
showing the current time of day and the colon will be flashing.
The system is fully operational.
During normal operation (Service mode) the display will
show the current time of day with the colon blinking. This will
alternate with a display of the capacity remaining.
