Low Water Level Warning Buzzer. The warning buzzer located in the upper right-hand corner, inside the
electrical control cabinet. It warns the operator when the water is low in the wet well. An ON-OFF toggle switch (1, fig.
2-1) controls the electrical circuit for the buzzer and warning light when the low water level sensitive switch is closed.
Low Water Warning Light. The low water level warning light (2, fig. 2-1) is a red light located on top of the
electrical control cabinet. It works in conjunction with the warning buzzer. If the light comes on during operation it
indicates that water in the wet well is low.
Effluent Launder Leveling Rods. The three effluent launder leveling rods (8, fig. 2-13) are attached to the
erdlator bridge rails and effluent launder. They support the effluent launder and are used to level it so the water will flow
into it uniformly throughout its entire circumference. It also assures an even flow of water to the wet well tank.
Blackout Toggle Switch. The toggle switch (3, fig. 2-4) is located on the ceiling by | the night door. The
switch Is for a 110 volt system.
Van Door Blackout Switches. The van door blackout switches (fig. 2-3) are located above the right door
and above the rear doors. When the ceiling light toggle switch is in the blackout position, the door switch will turn the
ceiling light off when doors are opened.
Chemical Solution Feeder Lever Arms and Indicators.
Feed indicators. The feed indicators (2 and 5, fig. 2-5) are mounted on the lever arms (1 and 7),
pointing toward the two feed scales (3 and 8). The position of the two feed indicators (2 and 5) on the lever arms (1 and
7) determines the amount of ferric chloride and calcium hypochlorite supplied to the water treatment section.
Driving arms. The driving arms (6 and 10, fig. 2-5) are attached to the chemical solution feeder by a
main shaft that extends through the feeder housing. The driving arms drive the two lever arms (1 and 7).
Lever arms. There are two lever arms (1 and 7, fig. 2-5) attached to the top of the chemical solution
feeder. The lever arms are used to actuate the diaphragm pushrods and springs (4), and operate the diaphragm pumps
of the chemical solution feeder. When necessary, after two wingnuts (9) have been loosened, the lever arms can be
used to prime the diaphragm pumps.
