Installation - Pentair MYERS SRM4 Serie Manual De Instalación Y Funcionamiento

INSTALLATION

This submersible sewage pump is designed for residential
wastewater removal, sewage applications, sump drainage,
dewatering and 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 handle allow
for easy disassembly after extended use.
This unit is not designed for applications involving salt water or
brine! Use with salt water or brine will void warranty.

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:
A PIPE SIZE OF
2" (51mm)
2-1/2"(64mm)
3"(76mm)
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.
CORD
For best performance of check valve when handling solids,

do not install it with the discharge more than 45° above
20
the horizontal. Do not install the check valve in a vertical
20
position as solids may settle in the valve and prevent it from
20
opening on startup.
30
Drill a 3/16" (5mm) hole in the discharge pipe about 1–2"

20
(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.
