SAFETY INSTRUCTIONS

• Hazardous Voltage. Can cause severe or fatal electrical shock. Do not plug in or unplug while standing on a wet floor or in water. Failure to follow this warning can result in fatal electrical shock.
• Risk of electrical shock. Do not lift the pump by the electrical cord; lift pump only by the discharge pipe, lifting ring or handle on the pump. Lifting by the cord can damage the cord.
• Do not smoke or use devices that can generate sparks in a septic (gaseous) environment.
•  Disconnect power to outlet box before unplugging pump.
• Take extreme care when changing fuses. Do not stand in water or put your finger in the fuse socket.
• Be sure that construction and access to septic sumps conform with all OSHA requirements.
•  Do not run the pump dry. Dry running can overheat the pump, (causing burns to anyone handling it) and will void the warranty.
• The pump normally runs hot. To avoid burns when servicing pump, allow it to cool for 20 minutes after shutdown before handling it.
• The pump is permanently lubricated. No oiling or greasing is required in normal operation. For overhaul, see instructions under “Service”.
• Vent sewage or septic tank according to local codes.
• This unit is not designed for applications involving salt water or brine! Use with salt water or brine will void warranty

ELECTRICAL

• DO NOT splice the electrical power cord. Do not modify the cord and plug. When using the cord and plug, plug into a grounded outlet only. When wiring to a system control, connect the pump ground lead to the system ground.
• DO NOT allow the electrical cord plug to be submerged.
• DO NOT use extension cords. They are a fire hazard and can reduce voltage sufficiently to prevent pumping and/or damage motor.
• DO NOT handle or service the pump while it is connected to the power supply.
• 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.
• DO NOT install pump in any location classified as hazardous by National Electrical Code, ANSI/NFPA or the Canadian Electrical Code.
• For automatic operation, plug or wire the pump into an automatic float switch or duplex controller. The pump will run continuously when plugged directly into an electrical outlet.
• 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 “Specifications” list.
• 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.

INSTALLATION

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. When installed in a sewage system, the pipe must be capable of handling semi-solids of at least 2” (51mm) 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 a sewage system use a 2” (51mm) or larger check valve in pump discharge to prevent back flow of liquid into sewage basin. The check valve should be a free flow valve that will easily pass solids. Be sure check valve installation complies with local codes.
• 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 3/16” (5mm) hole in the discharge pipe about 1–2” (25-51mm) above the pump discharge connection (but below check valve) to prevent air-locking the pump.
• 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.
• 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 distributor.

OPERATIONS

• Risk of fire or explosion. Can cause severe  personal injury, property damage or death. Do not use in explosive atmospheres.
• Do not allow the pump to run in a dry basin/tank. 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.

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 140OF (60OC).
3. Cutting or splicing a power cord or switch cord.
4. Anyone other than an authorized Myers service technician dismantling the pump.
5. Removing the cord tag from the cord.

SERVICE

Hazardous voltage and risk of cord damage. Can shock, burn or kill.

• Before removing the pump from the basin for service, always disconnect electrical power to the pump and the control switch.
• Do not lift the pump by the power cord. See the “Cord Lift Warning”.

DISINFECT THE PUMP

Place the pump in an area where it can be cleaned thoroughly. Remove all scale and deposit on the pump. Submerge the complete pump in a disinfectant solution (chlorine bleach) for at least one hour before disassembling the pump.

• The pump motor housing contains a special lubricating oil which should be kept clean and free of water at all times.
• Whenever the motor housing is being removed for service, remove oil and replace it with new oil at reassembly. Use only oil listed in parts list in this manual.
• When filling with new oil, DO NOT overfill. Fill with new oil so that the surface of the oil is 1/4″ above the motor windings

CHECK PUMP GROUND

1. Set the meter to Rx100
2. Touch one lead to the grounding pin and the other lead to one flat prong of the Repeat for the other prong.
3. Reading should be infinity for both prongs.
   • If the reading is anything other than infinity, the stator must be removed, dried and rechecked.
   • A reading of “0” indicates a dead short. Replace the pump.

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 it or attempting to remove.

PARTS LIST

Not Illustrated
If motor fails, replace entire pump.
