Commercial Variable Speed Pump can be programmed
to run at specic speeds and time intervals for maximum
operating eciency and energy conservation for a
variety of inground pools.
• The pump can operate at any speed between 300
RPM to 3450 RPM for dierent applications, with four
preset speeds of 1720, 2500, 3000 and 3450 (Quick
Clean).
• Alarm LED and error messages warn the user against
under and over voltage, high temperature and over
current, etc.
• Communicates with most Pentair automation systems
via the Digital Input Wiring Kit (P/N 353129Z- Almond)
or RS-485 Automation Wiring Kit (P/N 356324Z -
Black).
• Adjustable priming speed for easy start-up
• Compatible with most cleaning systems, lters, and
jet action spas
• WEF 5.0 THP 5.0
Motor Features
• Superior speed control for commercial applications
• Operates at lower temperatures due to high
eciency
• Designed to withstand outdoor environment
• 56 Square Flange Totally Enclosed Fan Cooled
(TEFC) Motor
• Low noise
Drive Assembly and Keypad
The pump features a variable frequency drive capable
of controlling the motor speed according to programmed
settings. This provides exibility in meeting your ltration
system’s specic needs.
The pump is intended to run at the lowest speeds
needed to maintain a sanitary environment and, at the
same time, minimize energy consumption. Factors
such as pool size, the presence of additional water
features, type of chemicals used to maintain sanitary
conditions, and local environmental factors will impact
optimal programming to maximize energy conservation.
Determining the optimal settings and programming for
your pool may require some trial-and-error.
Drive Features
• Active Power Factor Correction
• High Drive Operational Eciency
• Flow Control Capable when Paired with a 4-20mA
Flowmeter (Pentair P/N 97014-4203KIT).
• Versatile Power Input:
– Single-Phase, 208-230/277-460V, 20-21/17-11A
– 3-Phase, 208-460V, 13-6A
External Control
The pump can be externally controlled via digital inputs
using the Digital Input Wiring Kit (P/N 353129Z - Almond)
the RS-485 Automation Wiring Kit (P/N 356324Z -
Black). See External Control via Digital Inputs, page
6 or External Control via RS-485, page 5.
When connected to external controls, the pump will
prioritize commands as follows:
RS-485 > Digital Inputs > Drive Programmed Schedules
Refer to your control system manual for further details
on how to connect and program your pump with your
control system.
