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 plug. 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.

Do not touch an operating motor. Modern motors can operate
at high temperatures. Do not handle pump or pump motor
with wet hands or when standing on wet or damp surface, or in
water.
Personal Safety:
a. Wear safety glasses at all times when working with
pumps.
b. Keep work area clean, uncluttered and properly
