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.
