b. Disconnect tubing at the top of chamber (5) and from fitting (8) by loosening and removing tubing compression
c. Remove float chamber (5) by removing capscrews (1), Iockwashers (2), washers (3) and nuts (4).
Level switches must be installed in the exact position as removed.
a. Tag the switches (top, middle, bottom) locations and carefully mark the top of level switches(15, 17 and 19) on
chamber (5). Also mark the top of the two indicators(14) on chamber (5).
b. Remove level switches(15, 17 and 19) by loosening the screws in clamps (16, 18 and 20).
c. Remove sight indicators (14) by loosening screws in the four clamps (21).
d. Remove valve (6), nipple (7), fitting (8) and tee (9) by turning counterclockwise.
To avoid damage, do not allow fIoat to fall out of chamber.
e. Open clamp (10) and remove cap (11) and gasket (12).
f. Remove float (13).
a. Replace faulty or damaged parts with like serviceable parts.
b. Repair pipe fitting leaks by installing antiseize tape on the pipe threads.
c. Clean out any filter media in chamber (5) or in tubing attached to fitting (8) or the tubing attached to the top of
a. Use float(13) and slowly run it up or down flag indicators(14) to turn all flags white before installing on chamber
b. Attach a multi meter set to ohms x 1 to the A and B pins of each switch (1 5, 17, 19). Hold the individual switches in
the position shown in Figure 4-61 (wires up or down on the switch). Switch (1 5) should show no continuity (open) and
switches (17) and (19)should show continuity (closed). Use float (13)to change the switch to open or closed as indicated
above if they are not in the correct position by running it past switches until they change position.
Do not overtighten clamps. This could cause indicators and switches to crack.
Level switches must be correctly positioned in relation to sight indicator for proper
operation. Switches must be installed (180° from the sight indicators) with the wires
as shown in Figure 4-61. Switch (15) wires up and switches (17 and 19) wire down.
a. Install level switches(15, 17 and 19) by means of clamps(16, 18 and 20). Locate the switches by means of tags
and marks made during disassembly.
