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

Do not permit children to use this product.

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.

General Warnings

• Never open the inside of the drive motor enclosure. There is a
capacitor bank that holds a 230 VAC charge even when there is no
power to the unit.

• The pump is not submersible.

• The pump is capable of high flow rates; use caution when installing
and programming to limit pumps performance potential with old or
questionable equipment.

• Code requirements for electrical connection differ from country to
country, state to state, as well as local municipalities. Install equipment
in accordance with the National Electrical Code and all applicable
local codes and ordinances.

• Before servicing the pump; switch OFF power to the pump by
disconnecting the main circuit to the pump.

• This appliance is not intended for use by persons (including children) of
reduced physical, sensory or mental capabilities, or lack of experience
and knowledge, unless they have been given supervision or instruction
concerning the use of the appliance by a person responsible for their
safety.

FAILURE TO FOLLOW ALL INSTRUCTIONS AND
WARNINGS CAN RESULT IN SERIOUS BODILY

INJURY OR DEATH. THIS PUMP SHOULD BE INSTALLED AND

SERVICED ONLY BY A QUALIFIED POOL SERVICE PROFESSIONAL.
INSTALLERS, POOL OPERATORS AND OWNERS MUST READ
THESE WARNINGS AND ALL INSTRUCTIONS IN THE OWNER’S
MANUAL BEFORE USING THIS PUMP. THESE WARNINGS AND
THE OWNER’S MANUAL MUST BE LEFT WITH THE POOL OWNER.

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

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.

WHISPERFLOXF® VS and MAX-E-PROXF® VS Commercial Variable Speed Pump Installation and User’s Guide

IMPORTANT SAFETY INSTRUCTIONS

ii

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.

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

• A properly installed and secured ANSI/ASME A112.19.8 approved
anti-entrapment 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.

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.

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.

WHISPERFLOXF® VS and MAX-E-PROXF® VS Commercial Variable Speed Pump Installation and User’s Guide

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 qualified 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 specific model. All
models are intended for use in swimming pool applications. The pump
will function correctly only if it is properly sized to the specific 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.

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.

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.

INSTALLATION

Only a qualied plumbing professional should install the WhisperFloXF® VS and Max-E-ProXF® VS Commercial
Variable Speed Pumps. Refer to “Important Safety Instructions” on pages 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 the pump is secured to the equipment
pad.

6 IN. (15.2 CM)

MINIMUM

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 feet (1.5 meters) from the

inside wall of the pool and spa. Canadian
installations require a minimum of 9.8 feet
(3 meters) from the inside wall of the pool.

3. Install the pump a minimum of 3 feet

(0.9 meters) from a heater outlet.

4. Do not install the pump more than 10 feet

(3.1 meters) 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 inch pipe requires a 12.5 inch
(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 (5) 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 Requirements

• Install all equipment in accordance with the National

Electrical code and all applicable local codes and

ordinances.

• A means for disconnection must be incorporated in

the xed wiring in accordance with the wiring rules.

Electrical Installation

RISK OF ELECTRICAL SHOCK OR ELECTROCUTION. This 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, users or others due to electric shock.

Read all servicing instructions before working on the pump.

Note: ALWAYS reinstall the cover onto the eld wiring compartment when leaving the pump unsupervised. This will
prevent foreign matter (rainwater, dust, etc.) from accumulating inside the compartment.

Note: When connecting the pump to an automation system, continuous power must be supplied to the pump
by connecting it directly to the circuit breaker. When using an automation system, be sure that no other lights or
appliances are on the same circuit.

Wiring

DO NOT install this pump in conjunction with a

motor starter. Using a motor starter with this pump

can cause low voltage alarms and may cause permanent drive damage.

1. Be sure all electrical breakers and switches are
turned o󰀨 before wiring motor.

STORED CHARGE - Wait at least sixty

2. Be sure that the supply voltage meets the
requirements listed on the motor nameplate. If these
requirements are not met, permanent motor damage
may occur.

3. For wiring sizes and general guidelines for proper
electrical installation, please follow the specications
dened in the National Electric Code and any local
codes as required.

4. Use a strain relief and be sure all electrical
connections are clean and tight.

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

6. Wire the pump according to instructions given on the
inside of the eld wiring cover, then secure the eld
wiring cover with the four (4) corner screws.

Grounding

1. Permanently ground the motor using the green
ground screw (Figure 3). Use the correct wire size
and type specied by National Electrical Code. Be
sure the ground wire is connected to an electrical
service ground.

2. The pump should be permanently connected to either
a circuit breaker, 2-pole timer or 2-pole relay.

Note: If AC power is supplied by a GFCI circuit

breaker, the pump should be wired on its
own independent circuit unless the pump is

operated in tandem with a Pentair salt chlorine
generator.

3. A surge jumper has been factory-installed between
the two (2) bottom screw terminals in the wiring
compartment. Ensure this surge jumper is in place
before wiring the pump. See Figure 3.

This surge jumper grounds all drive components

and will protect them from repeated voltage
surges. If surge jumper is not installed damage to the pump drive may
occur.

Bonding

1. Bond the motor to the structure in accordance with
the National Electrical Code. Use a solid copper
bonding conductor not smaller than 8 AWG. For
Canadian installations, a 6 AWG or larger solid
copper bonding conductor is required. Run a wire
from the external bonding screw or lug to the bonding
structure.

2. Connect the wire from the accessible bonding lug
on 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 (1.5 meters) of the inside walls of the swimming
pool, spa, or hot tub. Run a wire from the external
bonding lug to the bonding structure. See Figure 3.

Note: When the pump is started and stopped by removing

External Control via Digital Inputs

When paired with either the Digital Input Wiring Kit (P/N 353129Z - Almond) or RS-485 Automation Wiring Kit (P/N
356324Z - Black), the pump can be externally controlled by digital input signals.

Note: If the pump is manually stopped using the

Start/Stop button, the pump will not run until the
Start/Stop button is pressed. If the Start/Stop

LED is illuminated, the pump is active and can be
controlled externally.

The communication cable provided with these kits
features a watertight connection that plugs into
the Pump Com Port (Figure 5 on page 5). The
opposite end of the cable has either 6 or 8 conductors
dened in Table 1.

A trigger signal is required to externally control the
pump via digital inputs. This required output signal can
to be provided in one of the following ways:

• By the pump drive. Refer to Using the Pump’s
Output Signal.

• By an external low voltage signal. Refer to Using
an External Input Signal on page 7.
