4. Remove the four screws holding the top control enclosure onto
the motor. Carefully lift the top panel and turn it over to expose the
inside terminal box.
(See Figure 2)
5. The terminal box is supplied with a 1/2” -14 NPT threaded hole.
Use only liquid tight fittings in order to protect the electronics and
the motor.
CAUTION: Failure to use liquid tight fittings will void the
warranty.
6. Connect L1, L2/N, and Ground to the terminal block as shown in
Figure 2.
7. Carefully fold all wires inside the terminal box and place the top
control panel back on top of the terminal box.
8. Tighten the four screws into the terminal box while applying light
pressure to the top control enclosure.
DO NOT OVER TIGHTEN

3. Insulate all connections carefully to prevent grounding or short-circuits. Sharp edges on terminals require extra protection.
To prevent the wire nuts from loosening, tape them using suitable, listed (UL, ETL, CSA) electrical insulating tape. For safety,
and to prevent entry of contaminants, reinstall all conduit and terminal box covers. Do not force connections into the conduit
box.

The correct voltage, as specified on the pump data plate, is necessary for proper performance and long motor life. Incorrect
voltage will cause the error light to turn on and cause damage to the motor if not turned off immediately.
It is the responsibility of the electrical installer to provide data plate operating voltage to the pump by ensuring proper circuit
sizes and wire sizes for this specific application.
CAUTION: Failure to provide data plate voltage during operation will cause the motor to overheat and void the warranty.
Voltage Checks
Pressure Test
WARNING:
When pressure testing a system with water, air is often trapped in the system during the filling process. This air
will compress when the system is pressurized. Should the system fail, this trapped air can propel debris at a high speed and
cause injury. Every effort to remove trapped air must be taken, including opening the bleed valve on the filter and loosening
the pump basket lid while filling the pump.
WARNING:
Trapped air in the system can cause the filter lid to be blown off, which can result in death, serious injury, or
property damage. Be sure all air is properly purged out of the system before operating. DO NOT USE COMPRESSED AIR TO
PRESSURE TEST OR CHECK FOR LEAKS.
WARNING: When pressure testing the system with water, it is very important to make sure that the pump basket and lid is
completely secure.
