WARNING

High voltages capable of causing severe injury or death by electrical shock are present in this unit.

To reduce risk of electrical shock, disconnect power before working on or around the system. More than one disconnect switch may be required to de-energize the equipment before servicing.
Be certain that this pump is connected to a circuit equipped with a ground fault circuit interrupter (GFCI) device.
Wire pump system for correct voltages.
Check local electrical and building codes before installation. The installation must be in accordance with their regulations as well as the most recent National Electrical Code (NEC), Occupational Safety and Health Act (OSHA), and Canadian Electrical Code (CEC).
This product is supplied with a grounding conductor and grounding-type attachment plug. To reduce risk of electric shock, be certain that it is connected only to a properly grounded grounding-type receptacle. Do not remove the third prong from the plug. The third prong is to ground the pump to help prevent possible electric shock hazard. Do not use an extension cord.
Check electrical outlets with a circuit analyzer to ensure power, neutral, and ground wires are properly connected. If not, a qualified, licensed electrician should correct the problem.
Be sure the electrical connection cannot be reached by rising water. Under no circumstances should the junction box be located where it may become flooded or submerged by water.

CAUTION
Risk of bodily injury, electric shock, or equipment damage.

This equipment must not be used by children or persons with reduced physical, sensory or mental abilities, or lacking in experience and expertise, unless supervised or instructed. Children may not use the equipment, nor may they play with the unit or in the immediate vicinity.
Do not use this pump for pumping any liquid intended for human consumption.
Equipment can start automatically. Always unplug the pump power cord and disconnect the electrical power before servicing the pump or switch. Lockout-Tagout before servicing equipment.
An inoperative or malfunctioning pump could lead to flooding, resulting in personal injury or property damage.
In applications where property damage and/or personal injury might result from an inoperative or leaking pump due to power outages, discharge line blockage, or any other reason, an automatic back-up system and/or an alarm should be installed.
Do not run the pump dry. If run dry, the surface temperature of the pump will rise to a high temperature that could cause skin burns if touched, and will cause serious damage to the pump.
Do not oil the motor. The pump’s motor housing is sealed, and contains a high-grade dielectric oil for heat transfer and lifetime lubrication. Use of other oils could cause serious electric shock and/or permanent damage to the pump.
The pump has been evaluated for use with water only. Pump should only be used with liquids compatible with pump component materials. If the pump is used with liquids incompatible with the pump components, the liquid can cause failure to the electrical insulation system resulting in electrical shock.
Operation of this equipment requires detailed installation and operation instructions provided in this manual for use with this product. Read entire manual before starting installation and operation. End User should receive and retain manual for future use.
Keep safety labels clean and in good condition.

NOTICE
Risk of damage to pump or other equipment.

Do not use this pump for pumping sea water, beverages, acids, chemical solutions, or any other liquid that pro- motes corrosion as this can result in damage to the pump.
Do not run pump dry. For optimal cooling and to prolong the motor life, the liquid level being pumped should normally be above the top of the pump housing.
This pump is not suitable for pond applications.

INSTALLATION

Physical Installation

WARNING
Risk of severe injury or death by electrical shock.

Always disconnect the electrical power before touching the pump or discharge.

NOTICE
Risk of damage to pump or other equipment.

Support pump and piping when assembling and when installed. Failure to do so may cause piping to break, pump to fail, motor bearing failures, etc.

Attach hose or other plumbing to pump discharge.
NOTE: The pump discharge is 1-1/4 inches NPT and the included adapter is 3/4 inches GHT.
Place pump in an upright position on a hard, level surface in the water reservoir.
• Never place pump directly on clay, earth, or gravel surfaces.
• Secure the pump so the starting torque does not cause the pump to contact anyone or anything.
Direct and secure the open hose or other plumbing end to desired water depository.

Electrical Connections
WARNING
High voltages capable of causing severe injury or death by electrical shock are present in this unit.

To reduce risk of electrical shock, disconnect power before working on or around the system. More than one disconnect switch may be required to de-energize the equipment before servicing.
The flexible jacketed cord assembly mounted to the pump must not be modified in any way, with the exception of shortening the cord to fit into a control panel. Any splice between the pump and the control panel must be made within a junction box mounted outside of the basin and comply with the National Electrical Code (NEC).
Employ a licensed electrician.

Connect the power cord to a constant source of power matching the pump nameplate voltage.
• Connect the pump to its own circuit, with no other electric receptacles or equipment in the circuit.
• Ensure that the fuses or circuit breaker are of ample capacity in the electrical circuit.
• Plug pump into a properly grounded receptacle.
Control power to the pump by plugging and unplugging the cord.

OPERATION

Storage

The pump automatically turns on every three minutes. It will run for 5 seconds to check if water is present. If water is present, the pump will run continuously until the water reaches the shut-off level. If no water is present, the pump will shut off for another three minutes.
IMPORTANT: If the drainage area refills at a quicker rate than the RL- MP25A’s operation cycle, change to a pump with a float switch mechanism.
NOTE: To start the pump manually, disconnect the cord from the power source, wait 5 seconds, then reconnect.
