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!

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 (For all permanently

installed units intended for use on 15 or 20 ampere, 125
through 240 volt, single phase branch circuits). Connect only to a branch
circuit protected by a ground-fault circuit-interrupter (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.

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

iii

IMPORTANT PUMP WARNING AND SAFETY INSTRUCTIONS

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.

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 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.

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.

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.

INSTALLATION

Only a qualified plumbing professional should install the WhisperFloXF® VS and Max-E-ProXF® VS Commercial
Variable Speed Pumps. Refer to “Important Pump Warning And Safety Instructions” on pages ii - iii 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.

Be sure the pump location meets the following
requirements:

1. Install the pump as close to the pool or spa as
possible. To reduce friction loss and improve
efficiency, use short, direct suction and return
piping.

2. Install a minimum of 5 feet (1.52 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 (.9 meters)
from the 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 five (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 inlet of
the pump. This will help the pump prime faster and
last longer.

Note: DO NOT install 90° elbows directly into the
pump inlet or outlet.

Figure 2: Recommended Piping

Fittings and Valves

1. Do not install 90° elbows directly into pump inlet.

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 five 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
significant 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 fixed wiring in accordance with the wiring rules.

Electrical Installation

RISK OF ELECTRICAL SHOCK OR ELECTROCUTION. This pump must be installed by a licensed or certified electrician or
a qualified 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 field wiring compartment when leaving the pump unsupervised during
servicing. This will prevent foreign matter (i.e. 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

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

STORED CHARGE - Wait at least sixty
(60) seconds before servicing.

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 specifications
defined 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 field wiring cover, then secure the field
wiring cover with the four (4) corner screws.

7. DO NOT install motor starters on these pumps.
These devices can cause low input voltage alarms.

Bonding Lug

Factory-Installed

Surge Jumper

Ground Wire

Connection

(Green Screw)

Grounding

1. Permanently ground the motor using the green
ground screw (see Figure 3). Use the correct wire
size and type specified 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 (1.52 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.

Figure 3

Note: When the pump is started and stopped by removing

power with a relay or timer, a two-pole device should be used to
apply and remove power to both POWER LINE TERMINALS.
