INSTALLATION & MAINTENANCE
MANUAL FOR THE JOCKEY
PUMP CONTROLLER
In order to familiarize yourself with the Jockey Pump Controller, please read the instruction manual thoroughly and
carefully. Retain the manual for future reference.
1. Installation and Mounting of the
Controller
Carefully unpack the controller and inspect
thoroughly.
It is recommended that the controller is located as
close as is practical to the motor it controls
The controller is not free standing and must be bolted
securely to a wall. For dimensional and weight data
please refer to the respective data sheets for the
Jockey Pump Controller.
2. System Pressure Connection
The Jockey Pump Controller is equipped with a
Pressure Switch. The controller is provided with a
¼” NPT female system pressure connection located
on the bottom, external side of the enclosure. The
connection should be installed as per NFPA,
pamphlet No. 20.
NOTE: Water lines to the pressure switch must be
free from dirt and contamination.
The pressure should not exceed what the pressure
switch is rated for.
3. Electrical Connections
All electrical connections should meet national
and local electrical codes and standards.
The controller should be located or so protected that
they will not be damaged by water escaping from
pumps or pump connections. Current carrying parts
of controllers shall be a minimum of 12 inches (305
mm) above the floor level.
•Prior to starting verify all data on the nameplate
such as, catalog number, AC line voltage and
horsepower.
•Inspect all electrical connections, components
and wiring for any visible damage and correct as
necessary. Ensure that all electrical connections
are tightened before energization.
•Install necessary conduit using proper methods
and tools.
•Incoming AC line voltage is clearly marked L1,
L2, L3 and ground, located at the top of the
breaker.

3.1 Electrical Checkout Instructions
WARNING: The following procedures should be carried out by a qualified electrician familiar with the electrical
safety procedures associated with this product and its associated equipment..
3.1.1 Motor Rotation Check: With the controller energized, move the H.O.A. selector switch to "HAND" then back to
“OFF” immediately to check the direction of the motor and pump rotation. If rotation direction is not correct,
open the breaker and reverse the phase sequence of the load terminals of the contactor T1, T2, T3 or at the motor
terminals.
3.1.2 Set up pressure switch set point as described on page 3 in these instructions. These instructions check out
automatic starting and stopping.
3.1.3 Starting and Stopping: Energize the controller. With the H.O.A. selector switch set to “AUTO”, if the system
water pressure is lower than the pressure switch set-point pressure, the pump will start. The pump will stop when
pressure is restored. If the optional running period timer is included, the pump will run for the set time and then
reset provided pressure has been restored. For manual operation, set the H.O.A. selector switch to “HAND’ to
start the pump and “OFF” to stop.
3.1.4 Overload Relay Trip Setting: The trip setting must be set as indicated on the drawing inside the starter door or
according to the chart at the back of this manual.
3.1.5 Running Period Timer: (Optional) The RPT timer must be set for a minimum of 10 minutes. A calibrated dial is
provided on the front of the timer.

3.2 Pressure Switch Setting Instructions
Before attempting to set the pressure switch, de-energize the jockey pump controller by opening the Circuit Breaker. This
is done for safety, and so that the jockey pump will not start and interfere with the adjustment procedure.
1. Set the differential adjustment on the pressure switch to minimum by turning the Differential Adjusting Screw fully
counter clockwise. Set the operating pressure to well below the required pump starting pressure. Turn the Range
Adjusting Screw clockwise to reduce the pressure and observe the scale on the switch.
2. Bleed the fire protection water system until the pressure is reduced to the required pump starting pressure. Hold this
pressure by closing the drain valve.
3. Slowly rotate the Range Adjusting Screw counter clockwise until a click is heard from the pressure switch. The
switch is now set to the required pump starting pressure.
4. If it is necessary to re-adjust the differential, the operating pressure of the switch will also be changed and should be
reset.
NOTE: The cut-in (start point) pressure is the cut-out (range adjusting setting) pressure minus the differential setting.
