ECOTECH EZ

TM

 Variable Speed Motor/Control

Basic motor/control operation

Your ECOTECH EZ

TM

 Motor/Control has been functionally 

tested for pool pump use before shipment. It is also 
preprogrammed to be a drop-in replacement for a standard 
single or two-speed pool pump motor with only minor 
programming required. To operate the motor/control, the 
installer must first set the time of day and the day of the 
week. Please see related informations of this manual for 
more specific information. 

Re-inspect the installation and make sure that guards  
and other protective devices are securely in place. All 
covers and gaskets must be re-installed prior to startup  
to minimize the entry of dirt and moisture. 

Blocked pump indicates there is an obstruction. Basic 
startup instructions are under the lid of the user interface. 
Detailed motor/control startup instructions begin on  
page 9 of this manual. In addition to these motor 
installation procedures, please follow all Startup & 
Operation instructions in your pump manual. 

The motor/control is designed to be operated on a 230 
volt, 60 Hz nominal power supply. The suitable voltage 
range is 207-253 volts under rated load conditions.

“Hot” power connections should only be connected to the 
L1 and L2 terminals of the above pictured motor/control 
conduit box connection area and supply ground (Green 
or Green with Yellow insulated lead wire) to the ground 
screw provided in this same connection area. Permanent 
field wiring should be from a 2-pole device. See Important 
Safety Instructions Section, Items a through d (page 5)

If AC power is supplied by a GFCI circuit breaker, use a 
properly sized dedicated circuit that has no other electrical 
loads. Use of a GFCI circuit with electrical loads other than 
the ECOTECH EZ motor/control could result in nuisance 
tripping. See Important Safety Instructions Section for 
more information.

Before performing any maintenance, disconnect the power 
and allow the motor to come to a complete stop then wait 
five(5) minutes before servicing.

This motor has permanently lubricated bearings. 

No further lubrication is recommended or required.

Important note: “fLoW” VS. “SpeeD” 

The motor/control is designed to operate at variable 
speed over a range of 1035 to 3450 RPM (revolutions 
per minute of the motor shaft). To make the product 
more understandable to use in pool pump applications, 
“FLOW” ( versus “SPEED” in RPM) terminology is used to 
represent changes in pump water output in both the user 
manual instructions and on the user interface display. A 
motor operational speed of 1035 RPM displays as “30% 
FLOW”, 1725 RPM displays as “50% FLOW”, and 3450 
RPM displays as “100% FLOW”. The Actual “% FLOW” 
rates will vary with the length of piping sections, use of 
fittings (elbows, tees, etc.), filters, heaters, and other 
components that affect system friction and efficiency, 
therefore, the “% FLOW” reading should only be used as 
an estimate of the actual system operating flow rate. When 
designing or calculating water turnover/exchange, the use 
of a properly calibrated and sized flow gauge should be 
used to determine actual operating flow rate (GPM) at the 
various operational speeds of the motor/control.
