PRESSURE TANK RECOMMENDATIONS
Minimum tank size is two gallons. Use a pre-charged pressure
tank with Intellidrive, as shown in Table 1. The tank size must
equal at least 20 percent of the pump’s rated flow in gallons
per minute (GPM), but cannot be less than two gallons capacity.
For example, a pump rated at 7 GPM would require a tank
of two gallons capacity or larger. A pump rated at 50 GPM
would require a 10 gallon tank or larger. Tanks larger than
10 gallons can be used, but may require adjustment of

Set pressure tank’s pre-charge to 70 percent of the system
operating pressure. When using an external set point as well
as an internal set point, pre-charge tank to 70 percent of the
lower setpoint of the two. Some applications may require a
different percentage when determining the setpoint.
TRANSDUCER CONNECTIONS
A 0-100 PSI 4-20 mA transducer is provided with Intellidrive. Install
the transducer downstream of tank, as shown in Figure 1. Install
transducer in a tee in a straight section of pipe with at least 1 foot
of straight pipe on each side of the tee (i.e., all fittings must be at
least 1 foot away from transducer).
Feed transducer cable through the open 1/2” conduit hole on
bottom of the Intellidrive enclosure.
Connect the red wire of the transducer cable to AI+, connect black
wire to AI–, and connect the cable shield to the metal cable shield
screw, as shown in Figure 9,
To connect the transducer wires:
1. Strip wire ½ inch.
2. Push spring terminal up with finger or slotted
screwIntellidriver.
3. Insert wires from bottom.
4. Release spring terminal.
INPUT POWER CONNECTIONS
The input power terminals are located on the lower left side
and are marked L1 and L2 (see Figure 9).
There is a ground screw for the input ground wire to the right
of the connector (torque to 10 inch lbs).
Feed wire through the 3/4” conduit hole on the bottom left
side and into appropriate terminals.
If wire is large enough to require a larger conduit hole, remove
the 1-1/4” knockout and use appropriate conduit connections
To determine the correct wire sizes for installation, see
Table 2.
The Pentair Pentek Intellidrive® Constant Pressure Pump
Controller only accepts 230V single phase input power.
If incoming power does not match this, have a qualified
electrician alter supply voltage to 230V/1Ph before connecting
it to the Intellidrive.
