The single-turn adjustable Speed Control, Figure 2, provides
variable flow operation. The green POWER On indicator lights
whenever the pump is operating. The Power On/Direction
Switch turns power on when either clockwise or counter-
clockwise pump rotor direction is selected. The MAX Button
is used for priming and purging and operates the pump at
maximum speed while depressed.
The rear panel, Figure 3, contains a DC power input jack for
connection of primary power and a 4-terminal barrier strip for
connection of remote start/stop and for a DC backup supply.
Remote Start/Stop: Terminals 3 and 4 on the rear panel
terminal strip, (Figure 3) are used for remote start/stop
operation. Pump direction and speed are not remotely
controllable. In non-remote operation, these terminals are
connected together by a shorting bar. For remote control by
switch closure, remove the shorting bar and connect the two
terminals of an isolated remote control switch or relay to
terminals 3 and 4. A closure of the remote switch contacts
will turn the pump system on. Opening the contact will
turn the pump system off.
WARNING: Be sure the Pump Drive is turned off
before proceeding. Loose clothing

could be caught in the drive.
