Always disconnect power
source before performing any work on or near
the controller, motor or its connected load. If
the power disconnect point is out-of-sight, lock

it in the open position and/or tag it to prevent unexpected
application of power. Failure to do so could result in fatal
electrical shock or bodily injury.

DO NOT handle pump with wet
hands or when standing in water as fatal electrical
shock could occur. Disconnect main power supply
before handling system for any reason.

Protect the power cable from
coming in contact with sharp objects, oil, grease,
hot surfaces or chemicals. DO NOT kink the
power cable. If damaged replace immediately.

NEVER leave the control box,
fused disconnect switch, or covers open (either
partially or completely) when not being worked
on by a competent electrician or repairman.

UNDERLOAD SENSITIVITY

The Artesian Drive controller is configured at the factory
to ensure detection of Underload faults in a wide variety
of pumping applications including dead head and run dry
conditions. In very rare cases (as with certain pumps in
shallow wells) this trip level may result in nuisance faults. If
the pump is installed in a shallow well, activate the controller
and observe system behavior. Once the controller begins to
regulate pressure, check operation at several flow rates to
make sure the default sensitivity does not induce nuisance
Underload trips. If it becomes necessary to desensitize the
Underload trip level, please call of Technical Support at 1-800­345-9422 for further details.

Serious or fatal electrical shock may result
from contact with internal electrical components. DO NOT,
under any circumstances, attempt to modify connections to
the drive until power has been removed and 10 minutes have
passed for internal voltages to discharge!

How it Works

SYSTEM DIAGNOSTICS

In addition to regulating system pressure and accurately
controlling motor operation, the Artesian Drive continuously
scans the system and can detect a variety of abnormal
conditions. If there is elevated risk of damage to a part of
the system, the drive will protect the system and display a
code for the fault. If possible, the drive will try to restart itself
when the fault condition passes.

PUMP SIZING – ARTESIAN DRIVE (CENTRIFUGAL)

The Artesian Drive is configured at the factory for use with
standard 3-phase motors and pumps.

NOTE: The Artesian Drives are factory programmed to
F&W pumps to provide optimum performance and motor
protection. The Artesian Drive can be used with other
pumps, but the maximum motor amperage needs to be
compared to the factory programmed current value (refer
to the Specifications section under the appropriate model).
If the maximum motor current varies more than 5% from
the programmed value, the motor current value in the drive
needs to be changed for motor protection and optimum
performance. For details on how to change this value in the
drive, please contact Technical Support at 1-800-345-9422.

event of a motor overload.

DRIVE CONFIGURATION

When sized correctly, the Artesian Drive systems are ready
to go right out of the box and need no configuration.
Under certain circumstances there are several programming
parameters that can be changed to accommodate non
standard systems. For further information to change these
parameters, please call Technical Support at 1-800-345-9422

IMPORTANT: This equipment should be installed by technically
qualified personnel. Failure to install it in compliance
with national and local electrical codes and within F&W
recommendations may result in electrical shock hazard, fire
hazard, unsatisfactory performance, or equipment failure.

Controller Location Selection

The drive’s enclosure is NEMA 1 rated

and is intended for indoor use only. It
should be mounted in a location that provides protection
from water spray/drips and only be accessed by trained and
authorized personnel.

The Artesian Drive controller is intended for operation in
ambient temperatures up to 104°F (40°C) at 230 VAC input.

Installation Guidance and Instructions

INITIAL CONDITIONS AND PRECAUTIONS

1. The Pump Station should be installed on flat surface rated

for the weight of the pump station. A properly sized
concrete slab is recommended.

2. Installation should be performed by licensed or qualified

personnel.

equipment (i.e. fork lift). Be sure all necessary lifting
equipment is used properly.

4. DO NOT ATTEMPT TO USE DRIVE SUPPORT BRACKET FOR
LIFTING THE PUMP STATION. The bracket will not support
the overall weight of the pump station.

5. The pump station must be installed according NEC and
local electrical codes. Proper electrical disconnect MUST be
installed in view of the pump station.

6. Ensure compliance with all applicable local, state, and
OSHA regulations when installing, operating, repairing, or
maintaining the pump station.

7. The pump station is manufactured to best ensure operator
safety under normal operating conditions. The manufacturer
will not take any responsibility for personal or equipment
damage if the equipment has been modified or if the
safeguards have been modified. Any proposed modifications
must be carefully documented (to include a risk analysis) by
the party proposing the modification; and coordinated with
and approved by the manufacturer. Otherwise, the customer
assumes all responsibility for its actions and subsequent
consequences.

INSTALLATION PROCEDURE

1. Position the skid in final location and attach to pad as
necessary. NOTE: For serviceability of the pump and
protection of discharge plumbing fixtures down line of the
pump station, it is recommended to incorporate unions and
isolation valves on the intake and discharge plumbing. If
deemed applicable, a bi-pass loop with properly placed
valves should also be incorporated into the installation.

2. Install plumbing to the intake of the pump. Note: For
proper functionality of the system it is not recommended
that a pipe size smaller than 2-1/2” is use on the intake of
the pump. Note: For suction lift applications, intake pipe
plumbing needs to allow for suction pipe to be filled by
external water source to prime the pump. Note: If the water
source for the pump station is susceptible to containing
debris, an appropriately sized filter should be installed prior
to the pump intake which should be checked & cleaned
regularly to avoid clogging the pump and/or degrade system
performance.

3. Install plumbing to discharge manifold. Note: For proper
functionality of the system it is not recommended that a pipe
size smaller than 2” is use on the discharge manifold. Note:
To avoid causing damage to the system, when tightening
onto the threads of the discharge manifold, a pipe wrench
should be used on the manifold to keep the manifold from
turning.

4. With supply power OFF, connect power supply cables to L1
& L3 terminals for single phase power supplied drives or L1,
L2 & L3 terminals for three phase supplied drives. Attach
ground wire to grounding lug on drive. See Figures 4 - 6 on
page 7 & 8 for depictions of each HP power supply wiring
connections.

3 & 5 HP Models: To avoid a fire hazard and
maintain validity of the UL listing, torque the power terminal
screws to 12 lb.-in. (1.4 N-m).

7.5 HP 3 Phase Model: To avoid a fire hazard
and maintain validity of the UL listing, torque the power
terminal screws to 13.2 lb.-in. (1.5 N-m).

and maintain validity of the UL listing, torque the power
terminal screws to 21.6 lb.-in. (2.5 N-M).
