Pump Sizing – SubDrive2W
The SubDrive2W is designed to convert a conventional 1/2 hp (0.37 kW), 3/4 hp (0.55
kW) or 1.0 hp (0.75 kW) pump system to a variable speed constant pressure system by
simply replacing the pressure switch. Maximum pump output using the SubDrive2W
is similar to the performance achieved using a pressure switch. Therefore, the pump
selection criteria are the same as if a pressure switch were used. (Refer to the pump
manufacturer’s literature for details of the pump selection procedure.)
If a pump and motor as described above are already installed in the system and the well
system components are in good working order, no further system upgrades are required.
However, if the existing pump and motor have not been properly chosen, or if the
components of the well system are not in good working order, the SubDrive2W cannot
be used to correct the problem or extend the life of aging components.
Drive Configuration
By default, the SubDrive2W is configured at the factory to run a 3/4 hp (0.55 kW)
system. To operate a 1/2 hp (0.37 kW) or 1.0 hp (0.75 kW) system, a DIP switch must
be re-configured to select the proper system rating. Failure to match the configuration
to the rating of the pump and motor may trigger erroneous faults.
To configure the SubDrive2W for a 1/2 hp (0.37 kW) or 1.0 hp (0.75 kW) system, locate
the DIP switch marked “SW1” at the bottom of the main circuit board. Use a small
screwdriver (provided) to change the DIP switch setting according to the chart as shown.

WARNING
!
Serious or fatal electrical shock may result from contact with internal electrical components.
DO NOT, under any circumstances, attempt to modify DIP switch settings until power has
been removed and 5 minutes have passed for internal voltages to discharge! Power must be
removed for DIP switch setting to take effect.
