All models with a plug-in power cords system should still have a qualified electrician inspect the outlet being used to ensure proper wiring. Grounding Grounded Blade Outlet Power Cord Switch Cord Figure 3 TESTRESET The control switch is a wide-angle system which prevents short cycling of the pump motor and the consequential problems that short cycling can cause. The switch can be mounted on the discharge pipe (just above the pump discharge flange). See illustrations for switch mounting arrangem

5. A single thirty-second tone will sound when power to the system is interrupted. The unit will reset automatically when power is restored. A three-second tone will sound every time the pump starts. Troubleshooting Chart Maintenance Always disconnect the electrical supply before attempting to install, service, relocate or perform any maintenance. If the power source is out of sight, lock and tag in the open (off) position to prevent unexpected power application. Failure to do so could result in

The pressure should be neutral at the center. Closing the adjuster lowers the neutral pressure point and opening the adjuster raises the neutral pressure point. Once the neutral pressure point has been adjusted, the combination air shutter should be adjusted so that the percent CO2 test must be made at the inlet side of the draft hood. If the CO2 reading is not within the recommended limits, then the combustion air shutter should be re-adjusted and then the neutral pressure point be rechecked an

Protect yourself and others by observing all safety information. Failure to comply with instructions could result in personal injury and/or property damage! Retain instructions for future reference. Submersible Utility Pump Description This portable, submersible utility pump is designed for non-automatic use in water. The units are equipped with an 8 ft. 3-prong grounding type power cord. The motor is oil filled and sealed for cooler operation. The discharge fitting is designed for convenient at

The pump motor is equipped with automatic resetting thermal protector and may restart unexpectedly. Protector tripping is an indication of motor overloading as a result of operating the pump at low heads (low discharge restriction), excessively high or low voltage, inadequate wiring, incorrect motor conditions, or a defective motor or pump. 14. This pump is designed to transfer water in cycles. Using this pump in a continuous duty application by manipulating the switch to stay on, will effect th
