Electrical Connections
Pump must be installed by a licensed electrician
and conform to National Fire Protection Associa-
tion (NFPA) codes 30 and 70. You, as the owner,
are responsible for seeing that the installation and
operation of your pump complies with NFPA codes
as well as any applicable state and local codes. Rigid
conduit must be used to install wiring.
Failure to follow these wiring instructions may
result in death or serious injury from shock, re

The pump must be properly grounded to avoid
personal injury. Operating an ungrounded or im-
properly grounded pump may result in death due
to electrical shock, re or explosion.
Electrical wiring and connections must be made only by
a licensed electrician in accordance with national, state
and local electrical codes regarding Class I, Division 1,

DANGER
This pump is equipped with an auxiliary AC accessory
lead. The third wire (red) is to be used to energize a
control circuit that operates a device such as a signal
light or a solenoid operated valve. Maximum amp draw
on the control circuit is 1 amp. If you do not need this
feature, ensure that the wire is insulated and enclosed
within the electrical cavity of the pump.
Connect pump to the proper voltage source. M-3130
series pumps are designed to operate on 115 VAC,
60 HZ or 230 VAC, 60 HZ. Connection to improper
voltage will damage pump. Pump is set at factory
for low voltage (115-volt). For high voltage applica-
tions (230-volt) see wiring diagram located inside
electrical coverplate.
Wiring Details
1. Remove electrical coverplate (Figure 2). Install
