The following information applies
throughout this manual to Gorman-
Rupp JS and JSV Series FM-Approved
Submersible pumps.
Before attempting to install, operate, or
service this pump, familiarize yourself
with this manual, and with all other liter-
ature shipped with the pump. Unfamil-
iarity with all aspects of pump operation
covered in this manual could lead to de-
struction of equipment, injury, or death
to personnel.
The motor powering this pump is FM-
Approved for Class 1, Division 1,
Groups C and D environments. Any liq-
uid level devices used with the pump
must be intrinsically safe for use in
these environments.
Any control box used to operate the
pump must be approved by the Gor-
man-Rupp Company for the application.
If the control box is to be installed in an
explosive environment, it must be a
Nema 7 rating or better. If a non-explo-
sion proof control box is used, it must be
located outside the explosive environ-
ment. Improper location of a non-explo-
sion proof control box could result in de-
struction of equipment, injury, or death
to personnel.
When installing or servicing the pump
or controls, follow all requirements for
the installation of wiring or electrical
equipment in hazardous locations as
outlined in the National Electric Code.
When entering the pump wet well for in-
stallation or service, follow all safety re-
quirements for confined space entry.
Failure to observe these requirements
could result in injury or death to person-
nel.
The electrical power used to operate
this pump is high enough to cause inju-
ry or death. Obtain the services of a qu-
alified electrician to make all electrical
connections.
Do not connect the pump motor directly
to the incoming power lines. The pump
motor is designed to operate through a
Gorman-Rupp approved control box
which provides overload protection and
power control; otherwise, the pump
warranty will be voided. Make certain
that the pump and control box are prop-
erly grounded, and that the incoming
power matches the requirements of the
pump and controls. Install and operate
the control box in accordance with the
National Electric Code and all local
codes. Failure to follow these could re-
sult in injury or death to personnel.
This pump is not designed to pump vol-
