Pentair MYERS MWS5 Serie Manual De Instalación, Operación Y Repuestos página 2

DESCRIPTION
These submersible sump/effluent and sewage pumps are
designed for effluent and wastewater removal, sump drainage,
dewatering, flood control. Units have built in thermal overload
protection with automatic reset. The mechanical seal and
bearings on the motor shaft are permanently lubricated.
Stainless steel hardware and a heavy duty lift out ring allow for
easy disassembly after extended use.
NOTICE: This unit is not designed for applications involving salt
water or brine! Use with salt water or brine will void warranty.

INSTALLATION
Hazardous voltage. Can shock, burn or kill.
Do not lift pump by the power cord. See "Cord Lift Warning"
on Page 3.
NOTICE: Install the pump on a hard, level surface (cement,
asphalt, etc.). Never place the pump directly on earth, clay or
gravel surfaces.
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.
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:
A Pipe Size Of:
1-1/2" (38mm)
2" (51mm)
2-1/2"(64mm)
3"(76mm)
In a sewage system use a 2" (51mm) 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.

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.
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 3/16" (5mm) hole in the discharge pipe about 1–2"
(25-51mm) above the pump discharge connection (but below
check valve) to prevent airlocking the pump.
Electrical
Hazardous voltage. Can shock, burn, or kill.
When installing, operating, or servicing this pump, follow the
safety instructions listed below.
DO NOT splice the electrical power cord.
1.
2. DO NOT allow the electrical cord plug 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.
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 "Motor, Switch and Cord
Specifications" chart.
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
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.
