Install Nozzle Hanger (Not applicable to pumps with
-RDP suffix)
Attention: The nozzle hanger for your pump was removed
before shipping to protect against damage.
To reinstall the nozzle hanger follow the steps below.
1. Remove the two (2) 1/4"-20 x 1/2" bolts from the switch
coverplate.
2. Place the nozzle cover on the switch coverplate and align
holes.
3. Insert the two (2) 1/4"-20 x 1/2" bolts through the nozzle
cover and thread into the switch coverplate. Torque bolts
to 45-60 in/lb (Figure 1).
Switch Locking Lever
Attention: The M-3120-RDP remote dispenser pump incor-
porates an external switch locking lever that locks the pump
switch in the “ON” position. The pump is typically shut off
using the remote dispensing device “ON-OFF” mechanism.
Electrical Connections
Pump must be installed by a licensed electrician and
conform to National Fire Protection Association (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, fire or explosion.
The pump must be properly grounded to avoid personal
injury. Operating an ungrounded or improperly grounded
pump may result in death due to electrical shock, fire 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, Group D
locations. Other codes may apply.
Thread for the conduit connection at the pump electrical box
is 1/2 inch FNPT.
A standard 15-amp breaker is recommended.
Figure 1
This pump is equipped with an auxiliary AC accessory lead. The
third wire (brown for 115-volt system and purple for 230-volt
system) 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-3120
Series Pumps are designed to operate on 115 VAC, 60 Hz.
M-3220 Series Pumps are designed to operate on 220-
240 VAC, 50/60 Hz. Connection to improper voltage will
damage pump.

Wiring Details
1. Remove electrical coverplate and O-ring (Figure 2). Install
conduit and cable from switchbox to pump electrical
box. Wiring must be in accordance with Class I, Division
1 requirements in the applicable national electrical code.
Note that the lead wires are factory-sealed isolating the
motor from the junction box.
Figure 3
2. Attach ground wire using the green ground screw located
inside the electrical box (Figure 3). The external bonding
connection is only a supplemental bonding connection
where local authorities permit or require such a connection.
For 115-volt system connect the power cable to the black
and white pump wires and the control circuit (if required)
to the brown wire. For 230-volt system connect the power
cable to the brown and blue wires and the control circuit (if
required) to the purple wire. Secure with wire nuts. Refer
to appropriate wiring diagram on Page 4.
