INSTALLATION

WARNING Hazardous voltage. Can shock, burn or kill. Do not lift pump by the power cord. See “Cord Lift Warning” below.
NOTICE: Install the pump on a hard, level surface (cement, asphalt, etc.). Never place the pump directly on earth, clay or gravel surfaces. Install the pump in a sump basin with a minimum diameter of 18″ (46cm).

Piping
Piping must not be smaller than pump discharge.
The pump is designed to operate partially or completely submerged in effluent liquids and pump semi-solid fluids up to 3/4″ (51mm) in diameter.
When installed in an effluent system, the pipe must be capable of handling semi-solids of at least 3/4″ (19mm) in diameter.
The rate of flow in the discharge pipe must keep any solids present in suspension in the fluid. To meet minimum flow requirements (2 feet per second in the discharge line), size the pipe as follows:

In an effluent system use a 1-1/2″ (38mm) check valve in pump discharge to prevent backflow of liquid into sump basin. The check valve should be a free flow valve that will easily pass solids. Be sure check valve installation complies with local codes.
Be sure that the wide-angle float switch hangs freely. It should not be able to come in contact with the sides or bottom of the sump pit.
Make sure the sump pit is free of any debris that could obstruct the intake volute or switch.
Use plumbing materials that are approved by local building codes when connecting pipes between pump and sewer outlet.
Notice: For critical indoor installations where additional high water protection is desired, install a “Q-Alert” audible alarm system in the sump pit. For outdoor installations,  confer with your Hydromantic distributor.
Connect the power cord to a 3-prong grounded AC receptacle.
WARNING Hazardous voltage. can shock, burn or kill. do not remove the grounding pin from the power cord.
Avoid using extension cords or 2-prong adapter plugs.
Insert the piggyback plug that comes from the wide-angle float switch directly into the power receptacle.
Insert the pump power cord directly into the back of the piggyback receptacle.
Test the pump installation by filling the sump basin with enough water to activate the pump and repeat this cycle until satisfied with pump operation.
Notice: For best performance of check valve when handling solids, do not install it with the discharge more than 45° above the horizontal. Do not install the check valve in a vertical position as solids may settle in the valve and prevent it from opening on startup.
Drill a 1/8″ (3mm) hole in the discharge pipe about 1–2″ (25-51 mm) above the pump discharge connection (but below check valve) to prevent relocking the pump.

Electrical
WARNING Hazardous voltage. can shock, burn, or kill. When installing, operating, or servicing this pump, follow the safety instructions listed below.

1. do not splice the electrical power cord.
2. do not allow the plug on the end of the electrical cord to be submerged.
3. do not use extension cords. They are a fire hazard and can reduce voltage sufficiently to prevent pumping and/or damage motor.
4. do not handle or service the pump while it is connected to the power supply.
5. do not remove the grounding prong from the plug or modify the plug. To protect against electrical shock, the power cord is a three-wire conductor and includes a 3- prong grounded plug. Plug the pump into a 3-wire, grounded, grounding-type receptacle. Connect the pump according to the NEC or CEC and local codes.

WARNING

Risk of electrical shock.
Can burn or kill.
Do not lift pump by power cord.

CORD LIFT WARNING

1. Attempting to lift or support pump by power cord can damage cord and cord connections.
2. Cord may pull apart, exposing bare wires with possibility of fire or electrical shock.
3. Lifting or supporting pump by power cord will void warranty.
4. Use lifting ring or handle on top of pump for all lifting/lowering of pump. Disconnect power to pump before doing any work on pump or attempting to remove pump  from sump.

For automatic operation (SHEF40A1 and A2), plug or wire the pump into an automatic float switch or duplex controller.
The pump will run continuously when plugged directly into anelectrical outlet (SHEF40M1 and M2).
Connect or wire pump to its own individual branch circuit with no other outlets or equipment in the circuit. Size fuses or circuit breakers according to the “Motor, Switch and Cord Specifications” chart.

WARNING: Risk of electrical shock and fire. can burn, kill or cause property damage. Be sure that power supply information (Voltage/ Hertz/Phase) on pump motor nameplate matches incoming power supply exactly. Install pump according to all electrical codes that apply.

Operation

WARNING: Risk of fire or explosion. can cause severe personal injury, property damage or death. Do not use in explosive atmospheres. Pump water only with this  pump.
NOTICE: Do not allow the pump to run in a dry sump. It will void the warranty and may damage the pump.
An automatic overload protector in the motor will protect the motor from burning out due to overheating/overloading.
When the motor cools down, the overload protector will automatically reset and start the motor.
If the overload trips frequently, check for the cause. It could be a stuck impeller, wrong/low voltage, or an electrical failure in the motor. If an electrical failure in the motor is  suspected, have it serviced by a competent repairman.
The pump is permanently lubricated. No oiling or greasing is required.
Cycle the pump at least once every month to be sure that the system is working satisfactorily.
NOTE: any of the following will void the pump warranty:

1. Submerging, plugging, damaging or taping shut a vented cord.
2. Pumping materials other than those the pump was designed to pump or continuously pumping water hotter than 120°F (49°C).
3. Cutting or splicing a power cord or switch cord.
4. Anyone other than an authorized Hydromantic service technician dismantling the pump.
5. Removing the cord tag from the cord.
