SECTION 6: RINSE CYCLE
1. Before initiating the RINSE CYCLE, the operator must ensure that the GranuFlo Dissolution Unit II
Access Port Lid is in place (do not fully secure) and the Main Transfer Ball Valve is in the CLOSED
position. Make sure input water supply valve is OPEN ( Figure 1).
Figure 1
2. The RINSE CYCLE consists of two RINSE Operations. Press the Rinse START button. The Fill Indicator
Light will illuminate indicating the RINSE CYCLE has started and the GranuFlo Dissolution Unit II is in
FILL Operation (Figure 2). Lift the Access Lid and look into the tank to verify that the tank is filling.

3. Once the 25 Gallon Level Sensor is reached, the process automatically
steps to RECIRCULATE Operation (Figure 3). The operation will run for a
twelve (12) minute period. During this operation, the Spray Ball and jets
shall operate in 3 minute intervals. With your safety glasses on, lift the
lid after the Spray Ball has stopped operating and ensure that the water
is level with 25 Gallon Level Sensor. Since the water will be swirling in the tank it is okay for the
level to be a little above the 25 Gallon Sensor, but you should ensure that the level is not rising.
During this time period, follow the procedure outlined on the following page to inspect and clean
the Spray Ball Ring if needed see Figure 4: Spray Ball Ring Inspection / Cleaning Instructions.
CAUTION! BEFORE INITIATING THE RINSE CYCLE, THE DRAIN HOSE MUST BE PLACED ABOVE A SUITABLE DRAIN. ALWAYS LEAVE
ACCESS PORT LID IN PLACE UNLESS MANUAL INSTRUCTS OTHERWISE.
CAUTION! IMMEDIATELY AFTER A COMPLETED RINSE CYCLE, MAKE A BATCH OF DRY ACID PRODUCT. DO NOT LEAVE THE
GRANUFLO DISSOLUTION UNIT II WITH ONLY TREATED WATER OR WETTED WITH ONLY TREATED WATER FOR 4 OR MORE HOURS SINCE
THE GRANUFLO DISSOLUTION UNIT II IS SUSCEPTIBLE TO BACTERIAL GROWTH. IF A GRANUFLO DISSOLUTION UNIT II IS FOUND TO BE
STANDING FOR 4 OR MORE HOURS WITH TREATED WATER OR WETTED WITH TREATED WATER, THEN A DISINFECTION CYCLE (SEE
SECTION 8.3 SODIUM HYPOCHLORITE (BLEACH) DISINFECTION, PAGE 23), MUST BE COMPLETED BEFORE THE DISSOLUTION CYCLE IS
STARTED.
1. Power Cord is connected to 115 Volt, 60 Cycle, Single Phase,
20 Amp, GFI protected circuit.
2. Be certain the Dissolution Unit Drain Hose is over a floor drain.
3. Purified water source is turned ON.
4. Transfer Line is connected to top of Dissolution Unit Tank.
