Installation of the Overheat Protection Manager on Pump Models Other than CM & CS
1. Mount flange as close to the pump discharge as possible. There must not be any valves located between the flange and the impeller(s) that would restrict waterflow
to the OPM. The flange has a Waterous 4-bolt pattern, dimensions are shown in Figure 4. An O-ring and (4) 7/16-14 x 1 in. long screws are furnished. Some pump
models may have a 4-bolt flange suitable for mounting the flange, if not, provisions must be made in the OPM supplied discharge piping for mounting.
CAUTION
To provide adequate overheat protection, the thermal relief valve and the thermal switch must be mounted in close proximity to the impeller(s).
2. Install the OPM thermal relief valve and the thermal switch in the 1/2” tapped holes. (See Figure 4). The valve shall be installed with the male end mounted on the
pump body.
3. Locate an area on the panel (1.625” x 2.75”) and cut out. (See Figure 5 on next page).
4. Insert the OPM control panel wiring through the opening on the panel. Attach the OPM control panel to the apparatus panel with hardware supplied.
5. Connect the extension cable between the thermal switch and the control panel.
6. Connect the power and the ground of the control panel to the appropriate source.
