IMPORTANT SAFETY INSTRUCTIONS

When installing and using this electrical equipment,
basic safety precautions should always be followed,
including the following:

1. READ AND FOLLOW

ALL INSTRUCTIONS.

2. (For all units) WARNING - To reduce the risk of

injury, do not permit children to use this product unless
they are closely supervised at all times.

3. (For all permanently-installed units intended for
use on 15 or 20 ampere, 125 through 240 volt, single
phase branch circuits) WARNING - Risk of Electrical

Shock. Connect only to a branch circuit protected by
a ground-fault circuit interrupter (GFCI). Contact a
qualied electrician if you cannot verify that a circuit is
protected by a GFCI.

4. WARNING - To reduce the risk of electric shock,
replace any damaged cord immediately.

5. (For hot tub and spa pumps) Do not install within an
outer enclosure or beneath the skirt of a hot tub or spa.

7. (For all permanently-installed units intended for use
on 15 or 20 ampere, 12 through 240 volt, single phase
branch circuits) The unit must be connected only to a

supply circuit that is protected by a ground-fault circuit­interrupter (GFCI). Such a GFCI should be provided by
the installer and should be tested on a routine basis. To
test the GFCI, push the test button. The GFCI should
interrupt power. Push the reset button. Power should
be restored. If the GFCI fails to operate in this manner,
the GFCI is defective. If the GFCI interrupts power
to the pump without the test button being pushed, a
ground current is owing, indicating the possibility of an
electric shock. Do not use this pump. Disconnect the
pump and have the problem corrected by a qualied
service representative before using.

8. TO REDUCE RISK OF ELECTRICAL SHOCK,
A copper bonding connector (8 AWG) is provided for
bonding the motor to all metal parts of the swimming
pool, spa, or hot tub structure and to all electrical
equipment, metal conduit, and metal piping within 5
feet of the inside walls of a swimming pool, spa, or
hot tub, when the motor is installed within 5 feet of the
inside walls of the swimming pool, spa, or hot tub.

6. (For permanently-installed pool or hot tub/spa
pumps) CAUTION - This pump is for use with

permanently-installed pools and may also be used
with hot tubs and spas if so marked. Do not use
with storable pools. A permanently-installed pool is
constructed in or on the ground or in a building such
that it cannot be readily disassembled for storage. A
storable pool is constructed so that it is capable of being
readily disassembled for storage and reassembled to
its original integrity.

NOTE: To installer and/or operator of the Speck
Swimming Pool Pump; the manufacturer’s warranty
will be voided if the pump is improperly installed and/
or operated.

INSTRUCTIONS!

SECTION 1 EQUIPMENT OPERATION AND MAINTENANCE

3/1 LOCATION

1. Locate the pump as close to the pool as practical.

Consult local codes for minimum distance between pool
and pump.

2. The piping should be as direct and free from turns or
bends as possible, as elbows and other ttings greatly
increase friction losses.

3. Place pump on a solid foundation which provides a rigid
and vibration-free support so that it is readily accessible for
service and maintenance.

4. Install the pump in a well ventilated location protected
from direct sunlight and excessive moisture. (rain,
sprinklers, etc.)

5. Protect the pump against ooding and excess moisture,
prevent foreign objects from clogging air circulation around
motor. All motors generate heat that must be removed by
providing proper ventilation.

6. DO NOT store or use gasoline or other ammable
vapors or liquids in the vicinity of this pump. DO NOT store
pool chemicals near the pump.

7. DO NOT remove any safety alert labels such as
DANGER, WARNING, or CAUTION. Keep safety labels

in good condition and replace missing or damaged labels.

5. Before starting the pump for the rst time, remove the
see-through lid. (Turn lid ring counterclockwise to remove.)
Fill strainer tank with water until it is level with the suction

inlet.

Replace lid with locking ring. Hand-tighten the

lid to make an air-tight seal. Do not use any tools to

tighten the lid.

6. When installing and using the motor, basic safety
precautions should be done by a licensed electrician in
accordance with local codes. Be certain that the motor
frame is grounded. Motor name plate has voltage, phase,
ampere draw and other motor information as well as wiring
connection instructions.

BONDING: As required by National Electrical Code Article
680-22, the pump motor must be electrically bonded to
the pool structure (reinforced bars, etc.) by a solid copper
conductor not smaller than #8 AWG (8.4 mm2) wire via the
external copper bonding lug on the pump motor.

GROUNDING: Permanently ground the pump motor
using a conductor of appropriate size. Connect to the #10
green headed ground screw provided inside the motor
terminal box,

For more information about the motor operation refer to the
motor manual on page 10.

NOTE: Do not connect to electric power supply until the
unit is permanently grounded

8. Provide access for future services by leaving a clear
area around the pump. Allow plenty of space above the
pump to remove lid and basket for cleaning.

3/2 INSTALLATION

1. When connecting pipework to pump with threaded ports

it is recommended that thread seal tape be used. If the
suction pipe is not sealed correctly, the pump will not prime
properly and will pump small volumes of water or none at
all.

2. When installing the pump, care should be taken to
see that the suction line is below water level to a point
immediately beneath and the pump to ensure quick priming
via a ooded suction line. The height between the pump
and the water level should not be more than ve (5) feet.

3. Suction and discharge line should be independently
supported at a point near the pump to avoid strains being
placed on the pump.

4. It is recommended to install a gate check valve in both
the suction and discharge line in the event that the pump
must be removed for servicing.

3/3 MAINTENANCE

The pump requires little or no service other than reasonable
care and periodic cleaning of the strainer basket.

NOTE: It is normal for a few drops of water to escape from
the mechanical seal from time to time. This is especially true
during the break-in period. The mechanical seal may come

worn and/or loose during the course of time, depending
on the running time and water quality. If water continually
leaks out, a new mechanical seal should be tted. After
long periods of NOT operational (seasonal storage, etc.),
the pump must be checked for ease of rotation while it is
switched off.

WARNING: Before servicing the pump, switch off the
circuit breakers at the power source. Severe personal
injury or death may occur if the pump starts while your
hand is inside the pump.

Place a screwdriver, Allen Wrench or appropriate tool in the
end of the motor shaft and turn it clockwise. OR Remove
the fan cover and turn the fan in a clockwise direction
manually. This may require removal of the cover at the rear
of the motor or small circular cap at the rear center of the
motor.

SECTION 1 EQUIPMENT OPERATION AND MAINTENANCE

3/3 MAINTENANCE - continued

To Replace the Mechanical Seal

To replace the mechanical seal, remove the eight (8) bolts
holding the casing to the seal housing. Slide the motor
part including the seal housing out. Remove impeller by
turning it counter-clockwise when facing it, while holding
the motor shaft with a 7/16” wrench or screwdriver at rear
end of motor. Pull the impeller from the motor shaft noting
the position of the seal. Remove the seal from the impeller
shaft. To re-assemble, reverse the process. Use only
water as a lubricant to install both sides of the seal. Make
sure both sides of the seal (ceramic and spring portion)
are clean. Gently wipe polished faces with soft and dry
cotton cloth. Surfaces can easily be damaged by dirt and
scratching. (Use a drop of loc-tite to secure the impeller

nut.)

3/4 WINTERIZING

CAUTION: The pump must be protected when
freezing temperatures are expected. Allowing the
pump to freeze will cause severe damage and void
the warranty.

There are two options when winterizing the pump:

Option 1: Drain all the water from the pump, system

equipment, and piping. Remove drain plugs. Do not
replace plugs. Store the plugs in the empty strainer
basket for winter. Keep the motor covered and dry.

Option 2: Drain all the water from the pump, system

equipment, and piping. Remove the pump and motor
from the plumbing and store indoors in a warm and
dry location.

Note: When the winter season is over the pump will
need to be check and primed prior to start.

CAUTION: DO NOT run the pump dry. If the pump
is run dry, the mechanical seal will be damaged
and the pump will start to leak at the seal. If this
occurs, the mechanical seal will need to be replaced.
ALWAYS maintain the proper water level in your
pool. Continued operation in this manner could cause
a loss of pressure, resulting in damage to the pump
casing, impeller, and mechanical seal.

SECTION 2 TROUBLESHOOTING GUIDE

PROBLEM POSSIBLE CAUSES SOLUTION

1. Pump will not prime. a. Suction air leak.

b. No water in pump.

c. Closed valves or blocked lines.

d. Low voltage to motor.

2. Motor does not turn. a. No power to motor.

b. Pump jammed.

3. Low ow. a. Dirty lter.

Make sure the see-through lid and o-ring are clean

PROBLEM POSSIBLE CAUSES SOLUTION

4. Noisy operation of motor. a. Bad bearings. Noise when shaft is turned up by hand. Motor is hot in
bearing area when running. Replace bearing.

5. Motor runs hot. These motors will run hot to the touch, however, this is normal. They are designed that

way. Thermal overload protector will function to turn them off if there is an overload or high
temperature problem. Excessive heat can be cause by:

a. Low voltage.

Increase size of electrical wire. Be sure motor is
operating on correct voltage.

b. Installed in direct sun.

c. Poor ventilation.

6. Noisy operation of pump. a. Air leak in suction line. Bubbles

in water returning to pool at inlet.

b. Restricted suction line due
to blockage or under size pipe.
Indicated by high vacuum reading
at pump suction.

c. Foreign matter (gravel, metal,
etc.) in pump impeller.

d. Cavitation.

7. Motor overload protection

“kicks out”.

a. Motor is not connected properly.

b. Low voltage due to under size
wire or low incoming voltage.

Shield motor from sun’s rays.

Do not tighten cover or enclosure motor.

Repair leak. Check suction pipe, see-through lid in
place? O-ring clean?

Remove blockage or increase suction pipe size. Make
sure strainer tank is clean. Are all suction valves fully
open?

Disassemble pump and remove foreign matter from
impeller.

Improve suction conditions. (Reduce suction life,
reduce number of ttings, increase pipe size.) Increase
discharge pressure and reduce ow by throttling
discharge valve.

Check wiring diagram on motor.

Check with volt meter. Increase size of supply wire.

a. All aspects of the installation shall conform to

the applicable requirements of the NEC (National
Electrical Code), including Article 430 (Motor Circuits
and Controllers), as well as all local codes.

b. This motor/control should be powered from a

separate circuit of adequate capacity to maintain

sufcient voltage during starting and running

conditions. Wire size shall be adequate to minimize

voltage drop during starting and running. A qualied

or licensed electrician should be used to properly size
the motor/control supply circuit. Reference articles
310 and 400 of the NEC for further information on
wire sizing. A #8 AWG or larger conductor must
be wired to the motor/control ground/bonding lug.

Use #6 AWG in Canada. Wiring, including exible

cords, should be as short as possible to minimize
voltage drop. All electrical connections in this

Basic Motor/Control Operation

Your ECOTECH EZ® 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 rst set the time of day and the day of the

week. Please see related informations of this manual for

more specic 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.

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

ve(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

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

ttings (elbows, tees, etc.), lters, heaters, and other
components that affect system friction and efciency,
therefore, the “% FLOW” reading should only be used as
an estimate of the actual system operating ow rate. When

designing or calculating water turnover/exchange, the use

of a properly calibrated and sized ow gauge should be
used to determine actual operating ow rate (GPM) at the

various operational speeds of the motor/control.

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

eld wiring should be from a 2-pole device. See Important

Priming the Pump

!

NOTICE

pump manufacturer’s product manual regarding the pump
priming operation.

For the factory default setting, every time the pump starts

from an Off condition (0% Flow), to ensure the pump is
properly primed, the pump will ramp to full speed (100%

Flow) for four minutes. When this occurs, the MAX icon will

be ashing above the percentage ow indicator. After the
priming time has expired, the pump will operate at the ow
percent that is shown in the display. If it is less than 100%,

the MAX icon will turn off.

The factory default setting can be changed to ows from
30% to 100% (in 5% increments), and time/duration from 0

to 10 minutes (in 1 minute increments), For NO PRIME, 0

minutes should be selected. During priming, the “% Flow”
indicator ashes. See page 18 Section F “Programming for

Pump Priming” for detailed instruction.

Please follow all instructions from the

Run Max Flow / Vacuum Mode

To enter this mode, press the Run Max Flow / Vacuum
button then press the Enter button. This mode provides an

operation of 100% Max Flow for a duration of 30 minutes.

These settings CANNOT be adjusted. While running in
this mode, the Timer on the user interface will show the

time remaining in the function and the percentage ow will
show 100% Max Flow.

If additional time is needed to clean and vacuum the pool,
or you would like to extend the time in this mode, pressing
the Run Max Flow / Vacuum button again before the timer
reaches zero minutes will reset the timer to 30 minutes.

After the completion of this mode, the unit will resume
running per the program schedule.

The Run Max Flow / Vacuum mode may be stopped at any
time by pressing the Exit button.

Manual Speed (Flow) Adjustment

While the pump is operating in any of the programmed

ow modes, (Mon-Fri, Sat-Sun, or Custom Flows), the ow

rate (speed) can be adjusted by pressing of the “Up” or
“Down” arrows. Each press of the “Up” arrow will increase

the % Flow by 5% increments until a maximum of 100% is

reached. Additional pushes of the key will have no further
effect. Each press of the “Down” arrow will decrease the

% Flow by 5 % increments until a minimum of 30% is

reached. Additional pushes of the key will have no further

effect. When the % Flow is changed manually with the

“Up” and “Down” arrow keys the setting is not stored, but

will be maintained until a change in ow is called for by the

program, or the operating mode is cancelled.

Run Custom Flow Mode

This function’s purpose is to allow for regular or special

!

NOTICE

It is good practice to check and/or reset
the current time of day and day of week settings on your
equipment pad time clocks in the event of a power outage
or during spring or fall time changes.

Pool Cleaners with Booster Pumps:

It is recommended to start your pool sweep one hour or

more after your ltration pump has started and stopping
the pool sweep one hour or more before your ltration

pump shuts off. If your pool cleaner operates on a time
clock, it is very important to set your pool sweep on and
off times per the above recommendation. Be aware of
the backup power supply feature on the ECOTECH EZ

®

motor/control as other time clocks may lose the correct
time in the event of a power outage. It is a good practice to
check and perhaps reset the current time of day and day
of week settings on your equipment pad time clocks in the
event of a power outage or in the event of a spring or fall
time change.

Refer to the manufacturer’s product manual for your pool
cleaner for proper cleaning time durations.

Pool Cleaners without Booster Pumps:

After your ECOTECH EZ

®

Motor/Control is running
and your pump is fully primed, refer to the pool sweep
manufacturer’s startup procedures then follow the
procedures for Run Max Flow / Vacuum mode found on
page 16 of this manual.

If an item has a timer regulating its operation, it can be
very important that the equipment pad item runs only when
the ECOTECH EZ

®

Motor/Control is running. Check the

item’s product manual to properly determine if the item

should run only when the ltration pump is running. If this

is the case, follow these instructions when synchronizing
the timer operations of your various equipment pad items.

Heaters:

If your pool heater has a time clock function, it is very

important to ensure the pool ltration pump is running

whenever the pool heater is running. The pool heater

should not run during times when the ltration pump is

off. The pool heater program timer setting should be set
to start and stop during the program on and off times

Fault Conditions

The user interface advises when certain fault conditions
occur. These fault conditions may be resolved at the
equipment pad.

Low Voltage Trip

The voltage to the motor/control conduit box terminals

must be 230 volts AC (Alternating Current), +/- 10% or

207-253 volts AC, 60 Hertz. A sustained input voltage

signicantly below 207 volts AC will cause a Low Voltage

Trip to occur. This trip will occur if 115 volts AC is applied
to the conduit box terminals instead of the required 230
volts AC. When this Low Voltage Trip occurs, the Call
for Service icon, the Attention icon and the Low Voltage
icon will illuminate on the LCD screen. The pump will
also shut down and automatically restart when operating

conditions are within specications. The pump will

begin ramping up to speed slowly until reaching the

percentage ow or speed for which the motor/control

was running prior to the fault occurring. When this fault
occurs, this could indicate a problem with the input line
voltage or wiring to the unit.

!

NOTICE

verifying that the input line voltage is between 207-253

volts AC, then call your pool professional or a qualied

electrician for service.

Blocked Pump Trip

The Blocked Pump fault is an indication of a mechanical

obstruction causing the motor shaft not to turn. When
this occurs, the Blocked Pump icon and the Attention
icon will illuminate on the LCD screen. The pump will
shut down. This is a self-resettable fault, meaning
the motor/control will attempt to restart by ramping to

the percentage ow for which the motor/control was
running prior to the fault. This reset will occur up to ve

times after which the user must press the Exit button to
recheck the system to determine if the Blocked Pump
condition still exists. If not, the pump will begin ramping

up to speed slowly until reaching the percentage ow

or speed for which the motor/control was running prior
to the fault occurring. If the condition still exists, the
fault will occur again.

If this fault continues to occur even after

Amps icon and the Attention icon will illuminate on
the LCD screen. The pump will shut down. This is
not a self-resettable fault and the user must press
the Exit button to recheck the system to determine if
the High Amps condition still exists. If not, the pump
will begin ramping up to speed slowly until reaching

the percentage ow or speed for which the motor/

control was running prior to the fault occurring. If
the condition still exists, the fault will occur again.

!

NOTICE

time and the High Amps condition still exists, the Call
for Service icon will illuminate.

Temp Trip Fault

The Temp Trip is an indication of an excessive operating

temperature that could damage the motor control.
When this occurs, the Temp Trip and Attention icon will
illuminate and the pump will shut down. After 5 minutes,
the motor will restart automatically, and if the temperature
has dropped to a safe value, will begin ramping up

to speed slowly until reaching the percentage ow or

speed the motor/control was running prior to the fault
occurring. During restart, if the operating temperature
is still excessive, the unit will shut down again for
another 5 minutes. When this fault occurs, this could
indicate inadequate ventilation around the product.
Make sure there is proper ventilation around the product
by removing any leaves or other items which may be

restricting the air ow around the motor and control.

All Internal Faults

Internal faults are failure conditions that do not have an

icon in the LCD display. These faults usually result in
control failure, but may be cleared by cycling the main
power. If the Attention and the Call for Service icons
illuminate and the pump has stopped, turn off the power
for 10 minutes at the main circuit breaker then turn the
power back on to reset the system. If this step does not
