System Commissioning
Step 1.
Begin by ensuring all
valves are in the closed
position.
Step 2.
Place the diffuser
basin into the filter. Adjust the
height of the CIP cleaning
arm, using the set screw
collar, so that it rests on the
surface of the filter media.
Attach the filter float valve
(figure 5-1).

Step 3.
Plug the solenoid valve electrical outlet into the storage tank upper float switch in a
piggyback fashion and plug into the wall outlet. Test the solenoid by moving the upper float
switch. The solenoid valve should open when the float switch is moved to the down position.
Step 4.
Open the filter inlet valve to begin filling. Adjust the mechanical float valve in the
filter such that the water level does not go higher than the filter overflow. Now wait until the
water level reaches the maximum water level in the filter (Figure 4-1).
Note
: See Table 2 to obtain the filter flow rate. It is critical that the filter be operated at this
flow. Faster flows will compact the upper sand layer, increase filter maintenance
requirements, and may cause poor filter performance. To ensure that this flow rate is
maintained the flow rate control valve should be set for the nominal flow rate as described in
the following steps and not moved from that position unless there is a significant change in
the inlet water temperature.
