1.3 Safety precautions
All safety codes, safety standards, and/or regulations must
be strictly observed in the installation, operation, and
maintenance of this device. The jockey lite jockey pump
controller is of an Across-the-Line starting method.
CAUTION
Completely read and understand the material presented in this
document before attempting installation, operation, or application of
the equipment. In addition, only qualified persons should be permitted
to perform any work associated with this equipment. Any wiring
instructions presented in this document must be followed precisely.
Failure to do so could cause permanent equipment damage.
2. Installation and electrical connections
2.1 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.
2.2 System pressure connection
The jockey pump controller is equipped with a pressure
transducer. The controller is provided with a ¼” npt female
system pressure connection located on the bottom, external
side of the enclosure.
ote:
N
Water lines to the pressure transducer must be free
from dirt and contamination. The pressure should not
exceed what the pressure transducer is rated for.
2.3 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.
Prior to starting, verify the ac line voltage on the nameplate
matches the supply voltage onsite. Also verify the motor fla
matches the information on the nameplate.
Inspect all electrical connections, components and
wiring for any visible damage and correct as necessary.
Ensure that all electrical connections are tightened
before energizing.
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 motor circuit protector.
2.4 Electrical checkout instructions
CAUTION
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.
2.4.1 Motor rotation check
With the controller energized, move the H-O-A selector
switch to “hand” and then back to “off” immediately
to check the direction of the motor and pump rotation.
If rotation direction is not correct, open the motor
circuit protector and reverse the phase sequence of
the load terminals of the contactor t1, t2, t3 or at the
motor terminals.
2.4.2 Starting and stopping
Energize the controller. With the H-O-A selector switch
set to “auto”, if the system pressure is below that of the
pressure switch set-point pressure, the pump will start. The
pump will stop when the system pressure is above the stop
point (start pr differential) of the pressure switch. If
the optional running period timer is included, the pump will
run for the set time and then stop, provided the pressure
is above the pressure stop point. For manual operation, set
the H-O-A selector switch to “hand” to start the pump and
“off” to stop the pump.
