Final Startup 47
Cat. No. 01029401
Initial Backwash of the System
1. In order to properly purge excessive air in the system. The pilot valve will need to be manually cycled following
the instructions in the GBE Programming for Commercial Softeners and Filters (except for HFxN) Manual (P/N
01027295). The inlet isolation valve should not be fully opened until this step is complete and all air from the
system has been purged.
2. Remain in the backwash position (position 2) for at least 5 minutes or until the water to the drain runs clear.
NOTE This step is especially important to follow if you have installed the Aqua-Sensor probe, because it
allows the probe to settle to its proper depth in the resin bed.
3. Cycle the pilot valve through the remaining steps and back to the home position unless you need to add water
to the brine tank. The outlet isolation valve must remain closed and the bypass valve must remain open until the
pilot valve is back in the home position (position 1).
Installation Wrap Up
Table 1 on page 3, provides the expected flow rates to the drain during the various steps of the regeneration process.
Creating Brine
Once salt has been added to the brine tank the control valve must be manually cycled to the brine refill cycle to create the
required amount of brine for the unit’s first regeneration. Allow the valve to refill for the cycle #4 programmed time.
NOTE If the control valve is not cycled to the brine refill cycle there will be no brine for regeneration.
NOTE The salt level must be checked frequently; in some cases, after each regeneration. After the brine refill
step is finished, add salt. To ensure complete brine saturation in wet storage, maintain a salt depth of
at least 18 inches.
NOTE Use the Table 8 and the GBE Programming for Commercial Softeners and Filters (except for HFxN)
Manual (P/N 01027295) to set the CTM Softener to the proper time for refilling the brine tank with water.
