GENERAL INFORMATION
INTRODUCTION
Pentair Pentek® Defender provides control of high voltage
(120/240 VAC) pumps. Pump operations can be controlled
through a mobile device or computer.
The Pentek Defender is designed to provide superior protection
for the water pump system. Going beyond simple pressure
switch function, the Pentek Defender constantly monitors
cycle rate, pressure, current, and voltage. When issues are
detected, the Pentek Defender takes action to notify the owner
or authorized dealer.
In addition to superior protection, the Pentair Pentek Defender
is easy to set up and adjust. Instead of turning screws to modify
setpoint and differential, changes are programmed directly with
any mobile device, tablet, or laptop. The same interface offers
easy access for fixing settings for incidents like dry run and
excessive run time.

Pre-installation
EXPLOSION HAZARD: When the well tank has
been in service and a change to a higher pre-charge pressure
is necessary due to a required change in the pressure switch
setting, failure to follow the below instructions can cause a
rupture or explosion, possibly causing serious personal injury or
death, and/or property damage.
Do not adjust or add pressure if there has been a loss of air.
Do not adjust the pre-charge pressure if there is visible
exterior corrosion.
Do not adjust the pre-charge pressure if there has been a
reduction of the pump cycle time or the pre-charge pressure
compared to its initial setting. This is because a reduction
in pump cycle time can result from loss of tank air pressure
which may indicate the presence of internal corrosion.
Any re-pressurization or additional pressure could result in
rupture or explosion.
Do not use with components or materials that are
incompatible with the unit.
PlumbIng
1.
The unit should be mounted as close as possible to the
pressure tank.
Locate the unit following all local codes. Do not
locate the unit where it can be affected by flooding.
2.
You may assemble the unit using a 1/4"NPT pipe nipple to a
"Tank Tee" or "Tank Cross" or adapt the unit to an in-line pipe
fitting. Use pipe sealing tape or pipe sealant. Tighten the unit
using the wrench flats provided on the bottom connection.
NOTE: DO NOT EXCEED 15 LB./FT. of torque.
NOTE: Do not allow pipe sealant or other contaminants to
enter the small port in the unit connection.
NOTE: A mechanical pressure gauge is not required. Use the
appropriate plug to block any unused ports.
Wiring
Install, ground, wire and maintain device in accordance with your
local electrical code and all other codes/ordinances that apply.
Consult your local building inspector for local code information.
Ground device permanently using wire of size and type specified
by approved local or national codes.
Risk of explosion. Do not ground to gas supply line.
NOTE: Connect ground wire first. Connect to ground first, then to
green grounding wire provided in the device. Ground connection
MUST be made to this wire. Do not connect motor to electrical
power supply until unit is permanently grounded; otherwise
serious or fatal electrical shock hazard may result.
For best ground connection, connect to grounded lead in service
panel or to metal underground water pipe or well casing at
least 10 ft. long. If plastic pipe or insulated fittings are used, run
PN1053 (06-10-20)
