Engineered for life

NOTE: Installation procedures may vary between states.

WARNING

CAUTION

Refer to your local electrical code for proper wiring procedures.

Disconnect all power before installing,

replacing or repairing. Voltages present in the control box, pressure switch, magnetic starter or other electrical apparatus can cause severe electrical shock.

Prior to installation check printed nomenclature on the Watt-Knot to ensure the voltage rating matches or exceeds installation voltage.

Due to the nature of this device, there are

no user serviceable parts inside. Do not take apart. Do not use if the case is damaged. Please dispose of properly.

Fully read and understand the Watt-Knot

installation instructions before installation. Electrical circuitry and connections thereto must be performed only by electrically qualiﬁed and knowledgeable pump servicemen.

Application

The 240 volt Watt-Knots can be applied to most pressure switches, control boxes, magnetic starters and a variety of other controls used on single phase, 2-wire or 3-wire systems and three phase systems. Maximum nominal voltage – 240.

The 480 volt Watt-Knot can be applied to magnetic starters, and other three phase controls. Maximum nominal voltage – 480.

The Watt-Knot is suitable for use on a circuit capable of delivering not more than 5000 RMS symmetrical Amperes when protected by CC, G, J, RK1, T, or K5 Class Fuses rated maximum 60A and minimum 250V (480V for AWK3460) with a short circuit interrupting rating of 5kA or higher or a Circuit Breaker rated maximum 60A and minimum 250V (480V for AWK3460) with an interrupt rating of 5kA or higher. Not recommended for use with Renewable Fuses.

INSTALLATION – SINGLE PHASE SYSTEMS

CONTROL BOX – Attach one black lead to line 1 and

the other black lead to line 2 terminals. The green lead must be connected to the control box ground terminal. Ground control box per grounding instructions.

PRESSURE SWITCH – Attach one black lead each to line terminals. Attach the green lead to the pressure switch ground terminal. Ground pressure switch per grounding instructions.

INSTALLATION – THREE PHASE SYSTEMS

Use only three phase Watt-Knots for three phase systems. DO NOT use two single

phase Watt-Knots on three phase systems. MAGNETIC CONTACTOR – Connect one black lead

each to line 1, line 2, and line 3 terminals. Connect green lead to ground terminal. Ground magnetic contactor enclosure or pumping panel enclosure per grounding instructions. The wires used to connect the Watt-Knot to power and ground should not be any longer than necessary and should avoid unnecessary bends.

GROUNDING INSTRUCTIONS

The Watt-Knot will provide adequate protection if a proper ground is used.

To complete grounding the control box, pressure switch, magnetic contactor enclosure or pumping panel enclosure, the Watt-Knot green ground wire should be grounded with #10 wire or larger to:

A. Well casing, if not plastic. B. Motor ground C. Copper ground Rod D. Galvanized pipe or rod driven into moist ground at

least 6 feet. E. Copper plumbing if connected to earth ground. F. Electrical aluminum conduit if connected to earth

ground.

Function

The Watt-Knot is speciﬁcally designed to protect electric pump motors and controls from damage as the result of transient voltage surges caused by lightning interference, switching loads and power line interferences.

Single phase Watt-Knots begin shunting transient voltage surges at 500 volts. Maximum single phase nominal voltage is 240 volts.

Three phase, 230 volt, Watt-Knots begin shunting transient voltage surges at 620 volts. Maximum three phase nominal voltage is 240 volts.

Three phase, 460 volt, Watt-Knots begin shunting at 1,000 volts. Maximum three phase nominal voltage is 480 volts.

The Watt-Knots are designed to withstand repeated transient voltage pulse currents up to 6,500 amperes resulting in superior protection, if installed and maintained properly.

CHECKING WATT-KNOT WITH A

MULTIMETER

Watt-Knot has a unique feature unlike other secondary surge arrestors in that it can be checked with a Capacitance meter.

1. Set selector knob on meter to capacitance

2. Connect one black Watt-Knot lead to one meter lead

3. Connect green Watt-Knot lead to the other meter lead

4. Capacitance for each lead, at a multimeter setting of

1kHz, should be 0.5 - 2nF. If a capacitance reading

other than 0.5 - 2nF is attained, the Watt-Knot should

be replaced.

TROUBLESHOOTING

Problem Cause Solution

1. Motor fails with Watt-Knot on Watt-Knot improperly grounded. Refer to grounding instructions. system.

or high voltage surge. Watt-Knot connected improperly. Refer to installation instructions.

Check all connections.

2. Motor overloads protector; fuses Watt-Knot damaged by lightning or Replace Watt-Knot

or circuit breakers will not hold. extreme current surge.

Motor failure unrelated to lightning Replace motor.

Not responsible for damage due to transient voltage surges.
