SAFETY - SECTION A
The following information applies
throughout this manual to Gorman‐
Rupp SF Series explosion‐proof sub­
mersible 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 ap­
proved by either CSA and/or FM for
Class 1, Division 1, Groups C and D en­
vironments. Refer to the nameplate on
your pump for agency approval inform­
ation. Any liquid level devices used with
the pump must be intrinsically safe for
use in these environments.
Any control box used to operate the
pump must meet all applicable local
and national codes 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
control box which provides overload
protection and power control; other­
wise, the pump warranty will be voided.
Make certain that the pump and control
box are properly grounded, and that the
incoming power matches the require­
ments of the pump and controls. Install
and operate the control box in accor­
dance with the National Electric Code
and all local codes. Failure to follow
these could result in injury or death to
personnel.
