IntelliFlo VS-3050 Installation and User’s Guide
Wiring the IntelliFlo VS-3050
To connect the pump to an AC power source:
1. Make sure all electrical breakers and switches are turned off before wiring motor.
2. Make sure that the wiring voltage is 230 VAC ± 10%.
3. Use #12 AWG for wire runs up to 100 feet and #10 AWG for lengths longer than 100 feet. When in
doubt use a heavier gauge (larger diameter) wire. Heavier gauge will allow the motor to run cooler and
more efficient.
4. Make sure all electrical connections are clean and tight.
5. Cut the wires to the appropriate length so they do not overlap or touch when connected.
6. Permanently ground the motor using the green ground wire, as shown below. Use the correct wire size
and type specified by National Electrical Code. Make sure the ground wire is connected to an electrical
service ground.
7. Bond the motor to the pool structure in accordance with the National Electrical Code. Use a solid
No. 8 AWG or larger copper conductor (No. 6 or larger in Canada). Run a wire from the external bonding
lug to the pool bonding structure, as shown below.
8. The pump should be permanently connected to either a circuit breaker, 2-pole timer or 2-pole relay.
If AC power is supplied by a GFCI circuit breaker, use a dedicated circuit breaker that has no other
electrical loads.
9. IMPORTANT: When connecting the pump to an automation system ( IntelliTouch, EasyTouch,
SunTouch and IntelliComm), continuous power must be supplied to the pump by connecting it
directly to the circuit breaker. When using an automation system, Be sure that no other lights or
appliances are on the same circuit.
NOTE: When the pump is started and stopped by removing power with a relay or timer,
a two-pole device should be used to apply and remove power to both POWER LINE TERMINALS.

Initial SVRS Setup and Operational Check
The following initial SVRS setup steps describe how to determine the maximum intended flow (GPM) and
pump speed (RPM) for the system, and to perform a simulated entrapment event.
1. The SVRS system should be initially setup for operation at maximum flow (see page 5).
2. If the system includes a filter, the filter must be in a clean condition prior to setting up the maximum flow
condition.
3. Remove the drain plug from the pump strainer housing and install the vacuum gage into the 1/4" NPT
housing opening.
