WIRING INSTRUCTIONS
WARNING:
Model 4137: Use 12-volt DC power source. Model 4138: Use 24-volt DC
power source. Higher DC voltage or AC voltage may cause serious damage
and/or personal injury.
Circuit must be properly fused to prevent possible fire hazard and/or damage
to pump and switch should the pump become jammed.
Caution:
All connections should be made using crimp-on connectors.
1. Electrical connections should be made as shown in Figure 4.
2. Using butt connectors for 16-gauge wire, splice fuse holder into positive
lead (brown) in a location easily accessible for changing fuses. Install
the specified fuse.
3. Run brown wire from sump system directly to the positive (+) battery
terminal. If using manual on/off switch, run brown wire from sump system
to the switch, then to the positive (+) battery terminal.
4. Connect black wire from the sump pump system to the negative (-)
battery terminal to complete the circuit.
5. Re-connect power and water, and test unit for proper installation.
Feed water into the sump; if the flow appears to be too low, check
wire connections.
Note:
Reversed connections will result in opposite impeller rotation, which
drastically reduces capacity and can cause premature pump failure.
MAINTENANCE INSTRUCTIONS
Drain the unit during the winter months when not in use. Disconnect and
drain all lines to the unit. Remove hold-down clamps and empty the unit.
In some installations, it may be impossible to completely drain the system.
Add a non-toxic RV/marine antifreeze to the shower drain and circulate it
throughout the system.
For improved performance, periodically clean the filter. Remove the
cover and slip the filter out for easy cleaning. Re-install the filter and
cover when finished.
