Switch Locking Lever
Attention: The PRO20-115RD remote dispenser pump
incorporates 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, re 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, re or explosion.
DANGER
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 in. FNPT.
A standard 15-amp breaker is recommended.
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. PRO20-115 Pumps
are designed to operate on 115 VAC, 60 Hz.
PRO20-230 Pumps are designed to operate on 220-240 VAC, 50/60
Hz. Connection to improper voltage will damage pump.
CAUTION
Wiring Details
1. Remove electrical coverplate and O-ring (Figure 2).

trical 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.

2. Attach ground wire using the green ground screw lo-
cated inside the electrical box (Figure 3). The external

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 ap-
propriate wiring diagram on Page 4.
