RISK OF ELECTRICAL SHOCK. Connect only to

a branch circuit protected by a ground-fault circuit­interrupter (GFCI). Contact a qualified electrician if you cannot verify that the
circuit is protected by a GFCI.

This unit must be connected only to a supply circuit

that is protected by a ground-fault circuit-interrupter
(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
flowing, indicating the possibility of an electric shock. Do not use this pump.
Disconnect the pump and have the problem corrected by a qualified service
representative before using.

This pump is for use with permanent swimming 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.

and knowledge, unless they have been given supervision or instruction
concerning the use of the appliance by a person responsible for their
safety.

SUCTION ENTRAPMENT HAZARD: STAY OFF
THE MAIN DRAIN AND AWAY FROM ALL SUCTION

OUTLETS!

RELEASE SYSTEM (SVRS) PROTECTION AND DOES NOT PROTECT
AGAINST BODY OR LIMB ENTRAPMENTS, DISEMBOWELMENTS (WHEN
A PERSON SITS ON A BROKEN OR UNCOVERED POOL DRAIN) OR HAIR
ENTANGLEMENTS.

THIS PUMP PRODUCES HIGH LEVELS OF SUCTION AND CREATES A
STRONG VACUUM AT THE MAIN DRAIN AT THE BOTTOM OF THE BODY
OF WATER. THIS SUCTION IS SO STRONG THAT IT CAN TRAP ADULTS
OR CHILDREN UNDER WATER IF THEY COME IN CLOSE PROXIMITY TO
A DRAIN OR A LOOSE OR BROKEN DRAIN COVER OR GRATE.

THE USE OF UNAPPROVED COVERS OR ALLOWING USE OF THE POOL
OR SPA WHEN COVERS ARE MISSING, CRACKED OR BROKEN CAN
RESULT IN BODY OR LIMB ENTRAPMENT, HAIR ENTANGLEMENT, BODY
ENTRAPMENT, EVISCERATION AND/OR DEATH.

The suction at a drain or outlet can cause:

Limb Entrapment: When a limb is sucked or inserted into an opening resulting

in a mechanical bind or swelling. This hazard is present when a drain cover
is missing, broken, loose, cracked or not properly secured.

Hair Entanglement: When the hair tangles or knots in the drain cover, trapping
the swimmer underwater. This hazard is present when the flow rating of the
cover is too small for the pump or pumps.

Body Entrapment: When a portion of the body is held against the drain
cover trapping the swimmer underwater. This hazard is present when the
drain cover is missing, broken or the cover flow rating is not high enough for
the pump or pumps.

Evisceration/Disembowelment: When a person sits on an open pool
(particularly a child wading pool) or spa outlet and suction is applied directly
to the intestines, causing severe intestinal damage. This hazard is present
when the drain cover is missing, loose, cracked, or not properly secured.

Mechanical Entrapment: When jewelry, swimsuit, hair decorations, finger,
toe or knuckle is caught in an opening of an outlet or drain cover. This hazard
is present when the drain cover is missing, broken, loose, cracked, or not
properly secured.

NOTE: ALL SUCTION PLUMBING MUST BE INSTALLED IN ACCORDANCE
WITH THE LATEST NATIONAL AND LOCAL CODES, STANDARDS AND
GUIDELINES.

THIS PUMP IS NOT EQUIPPED WITH SAFETY VACUUM

IMPORTANT SAFETY INSTRUCTIONS

ii

TO MINIMIZE THE RISK OF INJURY DUE TO
SUCTION ENTRAPMENT HAZARD:

• A properly installed and secured ANSI/ASME A112.19.8 approved anti­entrapment suction cover must be used for each drain.

• Each suction cover must be installed at least three (3’) feet apart, as
measured from the nearest point to nearest point.

• Regularly inspect all covers for cracks, damage and advanced weathering.

• If a cover becomes loose, cracked, damaged, broken or is missing,
replace with an appropriate certified cover.

• Replace drain covers as necessary. Drain covers deteriorate over time
due to exposure to sunlight and weather.

• Avoid getting hair, limbs or body in close proximity to any suction cover,
pool drain or outlet.

• Disable suction outlets or reconfigure into return inlets.

The pump can produce high levels of suction within

the suction side of the plumbing system. These high
levels of suction can pose a risk if a person comes within the close proximity
of the suction openings. A person can be seriously injured by this high level
of vacuum or may become trapped and drown. It is absolutely critical that the
suction plumbing be installed in accordance with the latest national and local
codes for swimming pools.

A clearly labeled emergency shut-off switch for the pump

must be in an easily accessible, obvious place. Make
sure users know where it is and how to use it in case of emergency.

The Virginia Graeme Baker (VGB) Pool and Spa Safety Act creates
new requirements for owners and operators of commercial swimming
pools and spas.

Commercial pools or spas constructed on or after December 19, 2008,
shall utilize:

(A) A multiple main drain system without isolation capability with suction
outlet covers that meet ASME/ANSI A112.19.8a Suction Fittings for Use in
Swimming Pools, Wading Pools, Spas, and Hot Tubs and either:

(i) A safety vacuum release system (SVRS) meeting ASME/ANSI
A112.19.17 Manufactured Safety Vacuum Release systems (SVRS) for
Residential and Commercial Swimming Pool, Spa, Hot Tub, and Wading
Pool Suction Systems and/or ASTM F2387 Standard Specification for
Manufactured Safety Vacuum Release Systems (SVRS) for Swimming
pools, Spas and Hot Tubs or

(ii) A properly designed and tested suction-limiting vent system or

(iii) An automatic pump shut-off system.

Commercial pools and spas constructed prior to December 19, 2008, with a
single submerged suction outlet shall use a suction outlet cover that meets
ASME/ANSI A112.19.8a and either:

(A) A SVRS meeting ASME/ANSI A112.19.17 and/or ASTM F2387, or

(B) A properly designed and tested suction-limiting vent system, or

(C) An automatic pump shut-off system, or

(D) Disabled submerged outlets, or

(E) Suction outlets shall be reconfigured into return inlets.

HAZARDOUS PRESSURE: STAND CLEAR OF PUMP
AND FILTER DURING START UP.

Circulation systems operate under high pressure. When
any part of the circulating system (i.e. locking ring, pump,
filter, valves, etc.) is serviced, air can enter the system
and become pressurized. Pressurized air can cause

the pump housing cover, filter lid, and valves to violently
separate which can result in severe personal injury or death. Filter tank lid and
strainer cover must be properly secured to prevent violent separation. Stand
clear of all circulation system equipment when turning on or starting up pump.

Before servicing equipment, make note of the filter pressure. Be sure that
all controls are set to ensure the system cannot inadvertently start during
service. Turn off all power to the pump. IMPORTANT: Place filter manual air

relief valve in the open position and wait for all pressure in the system
to be relieved.

Before starting the system, fully open the manual air relief valve and place
all system valves in the “open” position to allow water to flow freely from the
tank and back to the tank. Stand clear of all equipment and start the pump.

IMPORTANT: Do not close filter manual air relief valve until all pressure
has been discharged from the valve and a steady stream of water
appears. Observe filter pressure gauge and be sure it is not higher than the

pre-service condition.

General Installation Information

• All work must be performed by a qualied service professional, and

must conform to all national, state, and local codes.

• Install to provide drainage of compartment for electrical components.

• These instructions contain information for a variety of pump models

and therefore some instructions may not apply to a specic model.
All models are intended for use in swimming pool applications.
The pump will function correctly only if it is properly sized to the
specic application and properly installed.

Pumps improperly sized or installed or used in

applications other than for which the pump was
intended can result in severe personal injury or death. These risks may
include but not be limited to electric shock, fire, flooding, suction entrapment
or severe injury or property damage caused by a structural failure of the
pump or other system component.

Pumps and replacement motors that are single speed and one (1)
Total HP or greater cannot be sold, offered for sale, or installed in a
residential pool for filtration use in California, Title 20 CCR sections
1601-1609.

For Installation of Electrical Controls at Equipment
Pad (ON/OFF Switches, Timers and Automation
Load Center)

Install all electrical controls at equipment pad, such as
on/off switches, timers, and control systems, etc. to allow
the operation (startup, shut-down, or servicing) of any

pump or filter so the user does not place any portion
of his/her body over or near the pump strainer lid, filter lid or valve closures.
This installation should allow the user enough space to stand clear of the filter
and pump during system start-up, shut down or servicing of the system filter.

VS and SUPERMAX® VS Variable Speed Pumps Installation and User’s Guide

INSTALLATION

Only a qualied plumbing professional should install the pump. Refer to IMPORTANT SAFETY INSTRUCTIONS on
page i-ii for additional installation and safety information.

Location

Note: Do not install this pump within an outer enclosure

or beneath the skirt of a hot tub or spa unless marked
accordingly.

Note: Ensure that the pump is mechanically secured to
the equipment pad.

ENSURE THE INSTALL LOCATION MEETS THE
FOLLOWING REQUIREMENTS:

1. Install the pump as close to the pool or spa as
possible. To reduce friction loss and improve

e󰀩ciency, use short, direct suction and return piping.

2. Install a minimum of 5 ft. (1.5 m) from the inside wall
of the pool and spa. Canadian installations require
a minimum of 9.8 ft. (3 m) from the inside wall of the
pool.

3. Install the pump a minimum of 3 ft. (0.9 m) from the
heater outlet.

4. Do not install the pump more than 10 ft. (3.1 m)
above the water level.

5. Install the pump in a well ventilated location
protected from excess moisture (i.e. rain gutter
downspouts, sprinklers, etc.).

6. Install the pump with a rear clearance of at least
3 inches (7.6 cm) so that the motor can be removed
easily for maintenance and repair. See Figure 1.

Piping

1. For improved pool plumbing, it is recommended to
use a larger pipe size.

2. Piping on the suction side of the pump should be the
same or larger than the return line diameter.

3. Plumbing on the suction side of the pump should be
as short as possible.

4. For most installations Pentair recommends installing
a valve on both the pump suction and return lines
so that the pump can be isolated during routine
maintenance. However, we also recommend that a
valve, elbow or tee installed in the suction line should

be no closer to the front of the pump than ve (5)

times the suction line diameter. See Figure 2.

Example: A 2.5" pipe requires a 12.5" (31.8 cm)
straight run in front of the suction port. This will help
the pump prime faster and last longer.

Note: DO NOT install 90° elbows directly into the
suction or discharge ports.

Fittings and Valves

1. Do not install 90° elbows directly into suction port.

2. Flooded suction systems should have gate
valves installed on suction and discharge pipes
for maintenance, however, the suction gate valve

should be no closer than ve times the suction pipe

diameter as described in this section.

3. Use a check valve in the discharge line when
using this pump for any application where there is

signicant height to the plumbing after the pump.

4. Be sure to install check valves when plumbing in
parallel with another pump. This helps prevent
reverse rotation of the impeller and motor.

Electrical Installation

RISK OF ELECTRICAL SHOCK OR ELECTROCUTION. The pump must be installed by a licensed or certied electrician or a qualied

service professional in accordance with the National Electrical Code and all applicable local codes and ordinances. Improper installation
will create an electrical hazard which could result in death or serious injury to users, installers, or others due to electrical shock, and may
also cause damage to property.

Always disconnect power to the pump at the circuit breaker before servicing the pump. Failure to do so could result in death or
serious injury to service people, pool users or others due to electric shock and/or property damage.

Read all servicing instructions before working on the pump.

The pump accepts 115-230 V, 50 or 60 Hz single
phase input power. Power Connections (Figure 3) are
capable of handling up to 10 AWG solid or stranded
wire.

The motor controller will automatically regulate the
pump speed when running on lower voltage to keep
current below 13.6 A. No wiring change is required
to run the pump on 115 V nominal power, the same
terminals are used as with high voltage wiring.

The drive will operate on 2-Phase Line-Line-Ground
electrical systems as well as Line-Neutral-Ground
systems.

Wiring

1. Ensure all electrical breakers and switches are

turned o󰀨 before wiring the motor.

STORED CHARGE - Wait at least 5
minutes before servicing.

2. Ensure supply voltage meets the requirements
listed on the motor nameplate.

3. For wiring sizes and general requirements, follow

specications dened by the current National

Electric Code and any local codes. When in doubt
use a heavier gauge (larger diameter) wire.

4. Ensure all electrical connections are clean and
tight.

5. Cut all wiring to the appropriate length so they do
not overlap or touch when connected to terminals.

6. ALWAYS reinstall the drive lid after electrical
installation or before leaving the pump
unsupervised during servicing. This will prevent
rainwater, dust or other foreign matter from
accumulating in the drive.

Note: Ensure wires are not pinched between the

drive body and lid.

Grounding

1. Permanently ground the motor using the Grounding
Terminal (Figure 3) inside the drive wiring
compartment. Refer to the current National Electrical
Code and any local codes for wire size and type
requirements. Ensure the ground wire is connected to
an electrical service ground.

2. ONLY connect the pump to a supply circuit protected
by a ground-fault circuit-interrupter (GFCI) circuit
breaker.

Note: Pentair o󰀨ers a 2-Pole 20 Amp GFCI breaker

(P/N PA220GF).

Note: The pump should be wired to its own

independent circuit unless the pump is operated in

tandem with a Pentair salt chlorine generator.

Bonding

1. Using the Bonding Lug located on the side of the
motor (Figure 3), bond the motor to all metal parts of
the pool structure, electrical equipment, metal conduit
and metal piping within 5 ft. (1.5 m) of the inside walls
of the swimming pool, spa or hot tub in accordance
with the current National Electrical Code and any local
codes.

2. Solid copper bonding conductor of 8 AWG or larger is
required. For Canadian installations, 6 AWG or larger
solid copper bonding conductor is required.

Using an External Input Signal

When using an externally supplied low voltage signal for external control, input voltage must be within 5-30V AC/DC.
The wiring kit's RED wire is only intended to carry the +5V output signal from the drive and will NOT be used.

The +5V signal (RED wire) is output from the drive only and should never be wired to another power supply. Improper wiring
will damage the drive.

The external output signal can be regulated by switches or relays to initiate a desired pump function. If multiple digital
inputs are active, the priority is: QUICK CLEAN > SPEED 3 > SPEED 2 > SPEED 1.

TO WIRE FOR EXTERNAL CONTROL USING AN EXTERNAL INPUT SIGNAL:

1. Route the communication cable from the Pump
Com Port (Figure 5 on page 5) to the control

the drive: Press Display twice to exit the menu.

During a power outage, the drive will retain the clock
setting for as long as 24 hours. If the power is out longer
than 24 hours, the clock will have to be reset. If the drive
has lost the user set time, the clock will continuously
blink until the time is reset.

Note: When power is returned to the pump after
a prolonged outage (24+ hours) the clock will
automatically set itself to the Speed 1 start time, blink
and advance. The pump will also run the associated
schedule from that start time.

Using the Default Schedule

The default schedule is designed to provide su󰀩cient

daily turnover for a typical pool. See Table 2 for default
schedule.

Duration

(Hours)

SPEED 1 2 3000
SPEED 2 10 1400

Speed Priorities (Non-External Control)

For schedule duration settings, SPEEDs are
prioritized as follows: SPEED 1 -> SPEED 2 ->
SPEED 3. SPEED 1 is the highest priority, while
SPEED 3 is the lowest.

The drive will not allow a user to program a
schedule of more than 24 hours. When the 24th
hour of duration is programmed it will take time from
the lower priority speeds in order to add them to the
SPEED currently being adjusted.

Example:

Starting Schedule (Before Adjustment)
SPEED 1 duration = 20 hours
SPEED 2 duration = 2 hours
SPEED 3 duration = 2 hours

If the user reprograms SPEED 1 to run for
23 hours, SPEED 2 (lower priority speed) will
automatically adjust to a 1 hour duration and
SPEED 3 (lowest priority speed) will adjust to a
0 hour duration.

End Schedule (After Adjustment)
SPEED 1 duration = 23 hours
SPEED 2 duration = 1 hour
SPEED 3 duration = 0 hours

Operating the Pump While Running

If power is connected to the pump, pressing any of the

following buttons referred to in this section could result
in the motor starting. Failure to recognize this could result in personal injury or
damage to equipment.

Pressing the Display button will cycle through the current
parameters:

• Speed — current run speed

• Time — current time of day

• Duration — amount of time remaining at the

current run speed

• Watts — watts currently being consumed

Pressing any of the SPEED Buttons (“1”, “2”, “3” or Quick
Clean) while the pump is running will act as a temporary
override. The pump will run the speed and duration
programmed for that button. Once completed the pump will
return to the appropriate point in the programmed schedule.

Note: If schedule speeds are adjusted while the pump is
running, the pump will run the entered speed for the rest of
the program's duration, but will not save the adjustments.

Exception: Adjustments to QUICK CLEAN Speed and
Duration are always immediately saved.

Quick Clean

During a Quick Clean cycle, pressing the “+” or “-” will change
the speed accordingly. Pressing the Quick Clean button
again within 10 seconds of pressing “+” or “-” will allow you
to adjust Quick Clean duration. These changes will be
saved immediately and are the new defaults for Quick Clean.
Pressing the Quick Clean button again will cycle through the
two Quick Clean settings. The pump will exit editing mode if
no additional buttons are pressed within 10 seconds.

Note: While in keypad lockout mode the quick clean
feature is enabled and the "+" and "-" buttons can be used
to make temporary changes.

A Quick Clean cycle can be stopped early by pressing and
holding the Quick Clean button for 3 seconds. The pump will
return to the appropriate point in the programmed schedule.

When a connected control system is in Service Mode, a pump
connected via RS-485 can still run its Quick Clean program.
Once Service Mode is enabled the pump display will flash
between "SEr" and the current Quick Clean speed (Figure

12). Once Service Mode is disabled the pump will resume
normal operation.

Note: Quick Clean speed will read 0 when Quick Clean is off.

Priming

This pump is shipped with Priming mode ENABLED. The pump will ramp up to 3450 RPM when the pump is initially started.
Before turning the pump ON:

1. Open lter air relief valve.

2. Open necessary valves.

3. Ensure return line is completely open and clear of any blockages.

4. Ensure pump is lled with water.

5. Stand clear of the lter or other pressurized vessels.

DO NOT run the pump dry, the shaft seal will be damaged and the pump will start leaking. If this occurs, the damaged

seal must be replaced. ALWAYS maintain proper water level in your pool (half way up skimmer opening). If the water level

falls below the skimmer opening, the pump will draw air through the skimmer, losing the prime and causing the pump to run dry, resulting in a
damaged seal. Continued operation in this manner could cause a loss of pressure, resulting in damage to the pump body, impeller and seal and
may cause property and personal injury.

11

Priming will automatically run when the pump is
started, except when running a Quick Clean cycle.
Default Priming Speed is 3450 RPM, and will last for 5
minutes. The drive will display and cycle through “Prl

-- Priming Speed, Prl -- Remaining Time”.

If externally controlling the pump via an RS-485
connection and priming is enabled at both the
pump and control system: Both priming timers will

start simultaneously, but the pump priming settings will
have priority over the control system's.

Note: After the pump's priming cycle has
completed, if there is time remaining on the
control system's priming timer the pump will
run the control system priming speed until
the timer expires.

During the priming sequence, priming speed
can be adjusted between 1700 and 3450
RPM using the “+” and “-” arrows. Setting the
priming speed below 1700 RPM, will disable
priming and the pump will immediately begin
to run the scheduled speed.

When priming is disabled and the pump is
started, the screen will display, “
for 10 seconds while running the scheduled
speed (see Figure 11). This 10 second
delay allows time to enable priming by pressing “+”.

If priming is re-enabled, the pump will transition from
the scheduled speed to 1700 RPM. If necessary,
priming speed can then be increased 1700 RPM by
pressing “+”. The 5 minute priming countdown timer
starts when priming is first engaged.

Prl

--

OFF

”

Priming time can change based on local environmental
conditions such as water temperature, atmospheric
pressure, and your pool’s water level. All of these
things should be taken into consideration when setting
the priming speed.

Test and verify priming speeds more than once, letting
the water drain from the system in between each test.

Note: To prevent air from entering the system, the
pump strainer pot should always be filled with water
up to the bottom of the suction port.

MAINTENANCE

DO NOT open the strainer pot if pump fails to prime or if pump has been operating without water in the strainer pot. Pumps operated in

these circumstances may experience a build up of vapor pressure and may contain scalding hot water. Opening the pump may cause
serious personal injury. In order to avoid the possibility of personal injury, make sure the suction and discharge valves are open and strainer pot temperature is
cool to touch, then open with extreme caution.

Always disconnect power to the pump at the circuit breaker and disconnect the digital input cable before servicing the pump. Failure to do so could

result in death or serious injury to service people, users or others due to electric shock. Read all servicing instructions before working on the pump.

To prevent damage to the pump and for proper operation of the system, clean pump strainer and skimmer baskets regularly.

Cleaning the Pump Strainer Basket

The strainer pot is located at the front of the pump and
houses the pump strainer basket.

The strainer basket can be viewed through the strainer
pot lid and should be visually inspected at least once
a week. Regularly emptying and cleaning the strainer

basket will lead to higher lter and heater e󰀩ciency and

prevent unnecessary stress on the pump motor.

TO CLEAN THE STRAINER BASKET:

1. Press Start/Stop to stop the pump and shut o󰀨 all

electrical power to the pump at the circuit breaker.

2. Open the lter air relief valve and relieve all pressure

from the ltration system.

3. Turn the strainer pot lid counter-clockwise and
remove it from the pump.

4. Remove debris and rinse out the basket. Replace the
basket if it is cracked or damaged.

5. Place the basket into the strainer pot. Ensure the
notch in the bottom of the basket is aligned with the
rib in the bottom of the strainer pot.

6. Fill the strainer pot with water up to the inlet port.

7. Clean the lid O-ring and sealing surface of the strainer
pot.

Note: It is important to keep the lid O-ring clean and

well lubricated.

8. Reinstall the lid by placing it onto the strainer pot
and tightening clockwise until the lid handles are
horizontal.

Note: Ensure the lid O-ring is properly placed and is

not being pinched between the lid and strainer pot.

Note: Ensure that the side of the lid marked “Front”

is positioned at the front of the pump.

9. Open the lter air relief valve and stand clear of the

lter.

10. Reestablish electrical power to the pump at the circuit
breaker and start the pump.

11. When a steady stream of water ows from the lter air
relief valve, close the valve.

Winterizing

You are responsible for determining when freezing
conditions may occur. If freezing conditions are
expected, take the following steps to reduce the risk of
freeze damage. Freeze damage is not covered under

warranty.

In mild climate areas, when temporary freezing

conditions may occur, run your ltering equipment all

night to prevent freezing.

TO PREVENT FREEZE DAMAGE:

1. Press the Start/Stop button to stop the pump.

2. Disconnect all power to the pump at the circuit
breaker.

3. Relieve all pressure from the ltration system at the

lter air relief valve.

4. Remove both drain plugs from the bottom of the
strainer pot and drain the pump. Store the plugs in
the strainer basket.

5. Cover the motor to protect it from severe rain, snow
and ice.

Note: Do not wrap motor with plastic or other air
tight materials during winter storage. Never cover
the motor when operating or expecting operation.

THIS SYSTEM OPERATES UNDER HIGH PRESSURE. When
any part of the circulating system is serviced, air can enter the
system and become pressurized. Pressurized air can cause
the lid to separate which can result in serious injury, death, or
property damage. To avoid this potential hazard, follow above
instructions.

Shaft Seal Replacement

The Shaft Seal consists of two halves, a rotating spring seal
and a xed ceramic seal. The shaft seal may occasionally
become damaged and require replacement.

Scratching, marring or otherwise damaging the polished shaft
seal faces will cause the seal to leak. Always handle the shaft

seal faces with care and clean them thoroughly before reassembling the pump.

1. Ensure you have completed all pump disassembly instructions

on the previous page.

2. Remove the old Spring Seal from the impeller shaft with a pair

of pliers.

Note: When removing the spring seal the inner sleeve of

the seal may stick to the shaft. Ensure it is removed before
installing the new spring seal.

3. Place the seal plate face down on a at surface and tap out

the old ceramic seal with a at-blade screwdriver.

4. Flip the seal plate over and thoroughly clean the seal cavity.

5. Lightly lubricate the outside rubber surface of the new

ceramic seal with a silicone lubricant.

6. With the White Face upwards, rmly press the ceramic

seal into the seal plate cavity with your thumbs.

7. Thoroughly clean the seal face with a clean cloth.

8. Using a 9/16" wrench, secure the seal plate to the motor with
the four (4) motor bolts. Tighten to 75-80 in-lbs. (86-92 kg/cm).

9. With the Flat Face towards the impeller, slide the new
spring seal onto the impeller shaft.

10. Thoroughly clean the seal face with a clean cloth

11. Hold the motor shaft in place at the rear of the motor and

hand tighten the impeller clockwise onto the motor shaft.

12. Continue reassembling the pump according to the
instructions given in Pump Reassembly.

Motor Assembly Breakdown

Restarting the Pump

If pump is installed below the water level of the pool, close return and suction lines prior to opening the strainer pot on
pump. Make sure to re-open valves prior to operating.

DO NOT run the pump dry, the shaft seal will be damaged and the pump will leak. If this occurs, the damaged seal must

be replaced. ALWAYS maintain proper water level in your pool (half way up skimmer opening). If the water level falls below

the skimmer opening, the pump will draw air through the skimmer, losing the prime and causing the pump to run dry, resulting in a damaged
seal. Continued operation in this manner could cause a loss of pressure, resulting in damage to the pump body, impeller and seal and may
cause property and personal injury.

TO PRIME THE PUMP:

1. Press Start/Stop to stop the pump and disconnect all power to the pump at the circuit breaker.

2. Relieve all pressure from the ltration system at the lter air relief valve.

3. Remove the strainer pot lid by twisting it in a counter-clockwise direction.

4. Fill the strainer pot up to the inlet port with water.

5. Place the lid onto the strainer pot, then turn clockwise to lock in place.

Note: The lid is properly locked when the handles are nearly perpendicular to the pump body.

6. Return power to the pump at the circuit breaker.

7. Open the lter air relief valve.

8. Stand clear of the lter and press the Start/Stop button to start the pump.

9. Bleed air from the lter air relief valve until a steady stream of water appears, then close the relief valve.

10. The pump will run a priming cycle and, if successful, begin normal operation.

21 – Communication Link between the HMI and Motor Control has been lost: Remove the top cover from the drive
and inspect the jacketed wire on the backside of the keypad. Ensure that the 5-pin connector is properly plugged into the
socket and that there is no damage to the cable.

02 – Power Module Over Current Detected: If this error displays multiple times, then there may be a problem with the
pump’s rotating assembly. Disassemble the pump (see Pump Disassembly on page 15) and inspect the impeller and
shaft seal for problems.

Communication link between HMI and motor control has been lost

Power Module over current detected

Phase Current Offset out of range

Phase Current Imbalance detected

Absolute AC under voltage detected

Absolute Phase current limit exceeded

Absolute Diode Bridge temperature limit exceeded

Absolute Power Module temperature limit exceeded

Absolute Power Factor Correction (PFC) temperature limit exceeded

DC bus over voltage detected

DC bus under voltage detected

Motor start failure

AC Voltage maximum exceeded

0F – Absolute AC Under Voltage Detected: Indicates that the supply voltage has dropped below the operating range of
99v. This could be caused by normal voltage variation and will clear itself. Otherwise there could be excess voltage drops
caused by improper installation or improper supply voltage.

19 – Motor Start Failure: Could indicate a locked rotor. Verify the fan at the rear of the motor is free of debris. Attempt to
break up impeller blockages by rotating the motor shaft through the fan cover using a hex-key. If this does not work the
pump may need to be disassembled (see Pump Disassembly on page 15).

0b – AC Voltage Maximum Exceeded: Indicates that the supply voltage is exceeding the operating range of 251v.

1A,17,16, 02, 08, 04, 06, 09, 0A – Internal Errors: These errors can occur based on operating conditions and the required

self-diagnostic safety software. If they do not clear after multiple restart attempts the drive should undergo a hard power

cycle. Disconnect power at the circuit breaker long enough for the keypad LEDs to turn o󰀨. If the error continues to appear

after power is reconnected, the drive may need service.
