Introduction
The imPower motor is a permanent magnet alternating current (PMAC) electroni-
cally commutated motor (ECM), leveraging over 20 years of ECM technical and
manufacturing experience. The PMAC machine is inherently more eciency
than its induction counterpart, resulting in energy consumption savings of up to
85%. This imPower motor is designed to safely replace existing full-rated pool
lterpumpmotorsratedat3/4HP1.65SForup-ratedmotorsat1.0HP1.25SF.
This motor also features three selectable speeds either through the use of the
patent pending auto speed switch feature, top panel push buttons, external
multi-speed timers, or through external automation controls.

Operation
imPower motors are congured with Constant Speed, meaning they simply maintain
the speed (RPM) they are congured for in each application. This reduces the eect
lter cleanliness and product load have on the operation of the motor, unlike
traditional induction motors. The motor only uses the power (current) necessary to
operate at its programmed speed, and has the ability to automatically increase or
decrease power to maintain that speed.
imPower motors turn on and o with application of line voltage. This is critical to its
eectiveness with all existing line-power cuto timers and automation controllers.
Start up
During start up, motor current is slowly applied to motor windings. This provides a
controlled smooth start up. The motor/pump will accelerate to the high speed level
of 3450 rpm in approximately 6-8 seconds. Once started, the motor is programmed to
operate on high speed for two minutes to assure a proper prime is achieved, during
which time no attempt to change speeds will be recognized. Only after this two-min-
ute cycle will a change speed signal be accepted.
If no speed change signal is received by the motor after the two-minute prime cycle,
the motor will remain on high speed for a total of two hours, then automatically turn
down to one of the two reduced speeds. The factory default reduced speed setting
is “low” (1725 rpm), though this can be modied to “medium”(2600 rpm) if the ow/
pressure at low is deemed insucient for operation of certain poolside equipment/
features. The modication of the reduced speed automatic turn-down is found on
page 20 of this guide, titled“Automatic Reduced Speed Selection”.
Stall Detect (Locked Rotor Protection)
This feature protects the motor from external obstructions in the event it does not
achieve high speed operation within 15 seconds of applying voltage or if the RPM
drops below 500 RPM during operation. The imPower is programmed with a hard
fault feature such that the motor will automatically shut down if a stall detect fault
is registered. Power at the timer or automation controller must be removed and
reapplied after one minute of “dwell” time to restart the motor.
Overload Protection (Over-Current or Over-Temperature)
The imPower motor is specied with a series of sensors that continuously monitor the
temperature of critical internal components as well as the current owing through the
electronics. The motor will automatically shutdown if either limit is exceeded. Like the
stall detection, the timer or controller power must be removed, though it is recom-
mended that the motor power stay removed for at least 15 minutes to allow the motor
to cool and/or to determine the cause of the overload condition.

Topside Interface Overview
The topside interface on the imPower motor provides functionality to change
amongst three distinct preset speeds via either a button press or by a remote
timer / automation controller. Green display LED’s will light to indicate the
currently selected speed as well as to indicate power is applied to the motor. A
red Error LED is also included to show a fault identied by the on-board diagnostic
system.
The following are the LED lights that will shine in each normal operational
condition.
This condition is present:
1. Directly after energizing the motor
2. After selecting high speed via a button
press
3. After selecting high speed via a timer or
automation controller
This condition is present
1. After selecting medium speed via a but-
ton press
2. After selecting medium speed via an
automation controller
3. After two hours of high speed operation
if the factory default automatic speed
selection was changed to medium (refer
to page 20)
This condition is present
1. After selecting low speed via a button
press
2. After selecting low speed via an automa-
tion controller
3. After two hours of high speed operation
if the factory default automatic speed
selection was changed to medium (refer
to page 20)
Notes:
1. The red Error LED will blink once after power is applied to the motor. This
indicates the internal self-check has returned normal results.

Notes:
1. This connection allows the high speed and low speed to be operated
at any duration set by the multi-speed timer. At no point will the motor
automatically turn down to the selected reduced speed. The two-minute
prime cycle is still operation at initial start-up. The timer should be set
so that the pool can meet the total number of turns as required by local/
state regulations.
2. The user can override the operational speed currently running via the
buttons on the top control panel after the mandatory initial power-up
two-minute prime cycle. The override will continue until the motor is
either powered o by the multi-speed timer or a new speed is requested
by the multi-speed timer. At anytime, another speed can also be se-
lected via the top side control panel buttons.
3. In this type of connection, the motor will operate on high speed and
a reduced speed as dened by the multi-speed timer programming.
As noted in the“Operation” section of this manual, the factory default
reduced speed red lead setting is “low” (1725 rpm), though this can be
modied to “medium” (2600 rpm) if the ow/pressure at low is deemed

Step 17: Replace the impeller. Make sure that the impeller can spin freely in the
housing.
Step 18: Replace the diuser.
Step 19: Replace and tighten the bolts that retain the motor/seal plate assembly
to the pump.
Step 20: Connect the appropriately sized ground conductor to the supplied
grounding/bonding lug.
Step 21: Open the inlet and outlet valve.
Step 22: Reapply power and allow motor to accelerate to high speed and oper-
ate there for at least two minutes to assure adequate pump prime has
been established.

Notes:
1. The automation controller allows for the programmable operation of
all three speeds. The motor will start on high speed for each speed
selection and operate through its two-minute prime cycle before
reacting to any controller inputs. The on time and speeds should be set
so that the pool can meet the total number of turns as required by local/
state regulations.
2. The user can override the operational speed currently being set by the
automation controller via the buttons on the top control panel. The
override will continue until either the power is removed by the
automation controller or a new speed is requested by the automation
controller. Other than the initial start-up prime cycle, a change in speed
can be initiated at any time via the top side control panel buttons.

Automatic Reduced Speed Selection
The imPower motor has been programmed with a feature called the Automatic
Reduced Speed Selection function that allows for the maximum energy savings
via multi-speed operation despite using a standard single-speed timer. This
feature also applies to a multi-speed timer where the Circuit 2 speed can either be
assigned to medium or low speed.
The reduced default speed is factory set to switch to low speed operation after the
initial two-hour high speed operational period. However, it can be modied to
medium speed as required by minimum ow / pressure requirements of various
pool-side equipment / features as dened by manufacturer specications. The
default speed should only be modied during the rst two minutes of applying
power to the unit.
Please follow all local/state regulations regarding pool motor and timer speed
settings when choosing default reduced speed operation.
Step 1: Allow the pump to achieve prime if starting the system for the rst time.
Step 2: Turn power to the motor o at the timer / controller once pump prime
is reached. Also turn power o to the motor if prime was previously
reached and now motor/pump are operating as dened by the timer.
Step 3: Turn the motor on after allowing the motor to sit for at least 30 sec-
onds. Ensure that HIGH speed / Circuit 1 is being commanded if using a
multi-speed timer.
Step 4: After allowing the motor to come
to full speed, press and hold the
high and medium buttons simulta-
neouslyasshowninFigure18until
the low speed LED indicator light
begins to blink and then release.
Step 5: The low speed LED will continue to
blink for three seconds to indicate a
modication to the automatic
reduced speed turndown is being requested. After a brief pause, a sec-
ond series of LED blinks will indicate the new default setting has been
set to either medium speed (medium speed LED blinks) or low speed
(low speed led blinks).
Step 6: Turn the motor o, wait 30 seconds, turn back on to activate new setting.
