WARNING
– Pool and spa components (seals, gaskets, etc.) have a finite life. All components should be
inspected frequently and replaced at least every ten years, or if found to be damaged, broken, cracked, missing, or
not securely attached.
WARNING
–
Risk of Electric Shock.
All electrical wiring MUST be in conformance with applicable local
codes, regulations, and the National Electric Code (NEC). Hazardous voltage can shock, burn, and cause death or
serious property damage. To reduce the risk of electric shock, do NOT use an extension cord to connect unit to
electric supply. Provide a properly located electrical receptacle. Before working on pump or motor, turn off power
supply to the pump.
WARNING
– (For all cord- and plug-connected units) WARNING - To reduce the risk of
electric shock, replace damaged cord immediately.
WARNING
–
Risk of Electric Shock.
In accordance with the National Electric Code (NEC), 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. The 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 circuit 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.
WARNING
–
Suction Entrapment Hazard.
Suction in suction outlets and/or suction outlet covers, which
are damaged, broken, cracked, missing, or unsecured cause severe injury and/or death due to the following
entrapment hazards (symbols complements of APSP):
Hair Entrapment
- Hair can become entangled in suction outlet cover.
Limb Entrapment
- A limb inserted into an opening of a suction outlet sump or suction outlet cover that is damaged,
broken, cracked, missing, or not securely attached can result in a mechanical bind or swelling of the limb.
Body Suction Entrapment
- A differential pressure applied to a large portion of the body or limbs can result in an
entrapment.
Evisceration/ Disembowelment
- A negative pressure applied directly to the intestines through an unprotected
suction outlet sump or suction outlet cover which is damaged, broken, cracked, missing, or unsecured can result in
evisceration/disembowelment.
Mechanical Entrapment

WARNING
– To Reduce the risk of Entrapment Hazards:
−When outlets are small enough to be blocked by a person, a minimum of two functioning suction outlets per
pump must be installed. Suction outlets in the same plane (i.e. floor or wall), must be installed a minimum of
three feet (3’) [0.91 meter] apart, as measured from near point to near point.
−Dual suction fittings shall be placed in such locations and distances to avoid “dual blockage” by a user.
−Dual suction fittings shall not be located on seating areas or on the backrest for such seating areas.
−Never use pool or spa if any suction outlet component is damaged, broken, cracked, missing, or not securely
attached.
−Replace damaged, broken, cracked, missing, or not securely attached suction outlet components
immediately.
−In addition to two or more suction outlets per pump installed in accordance with latest APSP standards and
CPSC guidelines, follow all national, state, and local codes applicable.
−Installation of a vacuum release or vent system, which relieves entrapping suction, is recommended.
WARNING
–
Hazardous Pressure.
Pool and spa water circulation systems operate under hazardous
pressure during start-up, normal operation, and after pump shut-off. Stand clear of circulation system equipment
during pump start-up. Failure to follow safety and operation instructions could result in violent separation of the
pump housing and cover due to pressure in the system, which could cause property damage, severe personal injury,
or death. Before servicing pool and spa water circulation system, all system and pump controls must be in off
position and filter manual air relief valve must be in open position. Before starting pump, all system valves must be
set in a position to allow system water to return back to the pool. Do not change filter control valve position while
pump is running. Before starting pump, fully open filter manual air relief valve. Do not close filter manual air relief
valve until a steady stream of water (not air or air and water mix) is discharged from the valve. All suction and
discharge valves MUST be OPEN when starting the circulation system. Failure to do so could result in severe
personal injury and/or property damage.
WARNING
–
Separation Hazard.
Failure to follow safety and operation instructions could result in violent
separation of pump components. Strainer cover must be properly secured to pump housing with strainer cover lock
ring. Before servicing pool and spa circulation system, all system and pump controls must be in off position and
filter manual air relief valve must be in open position. Do not operate pool and spa circulation system if a system
component is not assembled properly, damaged, or missing. Do not operate pool and spa circulation system unless
filter manual air relief valve body is in locked position in filter upper body. All suction and discharge valves MUST be
OPEN when starting the circulation system. Failure to do so could result in severe personal injury and/or property
damage.
WARNING
– Never operate the circulation system at more than 50 PSI maximum.
WARNING
–
Fire and burn hazard.
Motors operate at high temperatures and if they are not properly
isolated from any flammable structures or foreign debris they can cause fires, which may cause severe personal
injury or death. It is also necessary to allow the motor to cool for at least 20 minutes prior to maintenance to
minimize the risk for burns.
WARNING
– Failure to install according to defined instructions may result in severe personal injury or death.

General Information
2.1.
Introduction
This manual contains information for the proper installation and operation of the Hayward VL Series Pump. The
instructions in this manual MUST be followed precisely.
2.2.
Product Dimensions
3.
Installation and Wiring
WARNING
– This product should be installed and serviced only by a qualified professional.
3.1.
Pump Location
Locate pump as close to pool as practical and run suction lines as direct as possible to
reduce friction loss. Suction lines should have continuous slope upward from lowest
point in line. Joints must be tight (but not over-tightened). Suction line diameter must
equal or be larger than the discharge line diameter.
Though the pump is designed for outdoor use, it is advised to place pump and filter in the
shade to shield them from continuous direct heat. Select a well-drained area that will not
flood when it rains. Do NOT install pump and filter in a damp or non-ventilated location. Keep motor clean. Pump
motors require free circulation of air for cooling.
3.2.
Pump Mounting
Install pump on a level concrete slab or other rigid base to meet all local and national codes. Secure pump to base
with screws or bolts to further reduce vibration and stress on pipe or hose joints. The base must be level, rigid, and
vibration free.
Pump mount must:
•Allow pump inlet height to be as close to water level as possible.
•Allow use of short, direct suction pipe (to reduce friction losses).
•Allow for valves in suction and discharge piping.
•Be protected from excess moisture and flooding.
•Allow adequate access for servicing pump and piping.

WARNING
–
Hazardous Pressure
. Pumps, filters, and other equipment/ components of a swimming pool
filtration system operate under pressure. Incorrectly installed and/or improperly tested filtration equipment and/or
components may fail resulting in severe personal injury or death.
3.3.
Plumbing
1. Fittings (elbows, tees, valves, etc.) restrict flow. For better efficiency, use the fewest possible fittings. Avoid
fittings that could cause an air trap. Pool and spa fittings MUST conform to the International Association of
Plumbing and Mechanical Officials (IAPMO) standards.
2. Union fittings should be connected hand tight. Do not over tighten the fittings as damage may occur.
3.4.
Electrical
WARNING
– All electrical wiring MUST conform to local codes, regulations, and the National Electric Code
(NEC).
WARNING
– Connect only to a grounded, 3 pin, GFCI protected outlet
3.5.
Voltage
Voltage at pump MUST NOT be more than 10% above or below nameplate rated voltage, or components may
overheat, causing overload tripping and reduced component life. If voltage is less than 90% or more than 110% of
rated voltage when pump is running at full load, consult the power company.
3.6.
Grounding
1. Install, ground and wire pump in accordance with local or national electrical code requirements.
4.
Startup & Operation
4.1.
Starting/Priming the Pump
Fill strainer housing with water to suction pipe level. If water leakage occurs from anywhere on the pump or filter,
DO NOT
start the pump. If no leakage occurs, stand at least 10 feet from pump and/or filter and proceed with
starting the pump.
WARNING
– Return to filter to close filter manual air relief valve when a steady stream of water (not air or air and
water) is discharged from valve. Failure to do so could result in severe personal injury.
ATTENTION
–
NEVER OPERATE THE PUMP WITHOUT WATER
. Water acts as a coolant and lubricant for the
mechanical shaft seal. NEVER run pump dry. Running pump dry may damage seals, causing leakage, flooding, and
voids warranty. Fill strainer housing with water before starting motor.
ATTENTION
– Do NOT add chemicals to pool/spa system directly in front of pump suction. Adding
undiluted chemicals may damage pump and voids warranty.
ATTENTION
– Before removing strainer cover:
1. STOP PUMP before proceeding.
2. CLOSE VALVES in suction and outlet pipes.

USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
Page 8 of 15
VL Series Pump
ISVL1285 Rev B
3. RELEASE ALL PRESSURE from pump and piping system using filter manual air relief valve. See filter owner’s
manual for more details.
4. If water source is higher than the pump, pump will prime itself when suction and outlet valves are opened. If
water source is lower than the pump, unscrew and remove strainer cover; fill strainer housing with water.
5. Clean and lubricate strainer cover O-ring with "Jack's 327" if necessary.
6. Replace strainer cover on strainer housing; turn clockwise to tighten cover.
NOTE - Tighten strainer cover lock ring by hand only (no wrenches).
Turn on power and wait for pump to prime, which can take up to fifteen (15) minutes. Priming time will depend on
vertical length of suction lift and horizontal length of suction pipe. If pump does NOT prime within 15 minutes, stop
motor and determine cause. Be sure all suction and discharge valves are open when pump is running. See
Troubleshooting Guide.
5.
Maintenance
•Clean strainer basket regularly. Do NOT strike basket to clean. Inspect strainer cover gasket regularly and replace as
necessary.
•Hayward pumps have self-lubricating motor bearings and shaft seals. No lubrication is necessary.
•Keep motor clean. Insure motor air vents are free from obstruction to avoid damage. Do NOT use water to hose off
motor.
•Occasionally, shaft seals must be replaced, due to wear or damage. Replace with genuine Hayward seal assembly
kit. See “Shaft Seal Change Instructions” in this manual.
6.
Storage / Winterization
WARNING – Separation Hazard.
Do not purge the system with compressed air. Purging the system with
compressed air can cause components to explode, with risk of severe injury or death to anyone nearby. Use only a
low pressure (below 5 PSI), high volume blower when air purging the pump, filter, or piping.
ATTENTION
– Allowing the pump to freeze with water in it will void the warranty.
ATTENTION
– Use ONLY propylene glycol as antifreeze in your pool/spa system. Propylene glycol is non-
toxic and will not damage plastic system components; other anti-freezes are highly toxic and may damage plastic
components in the system.
Drain all water from pump and piping when expecting freezing temperatures or when storing pump for a long time
(see instructions below). Gravity drain the system as far as possible.
Keep motor dry and covered during storage. To avoid condensation/corrosion problems, do NOT cover or wrap pump
with plastic film or bags.
6.1.
Storing Pump For Winterization
WARNING –
To avoid dangerous or fatal electrical shock hazard, turn OFF power to motor before draining
pump. Failure to disconnect power may result in serious personal injury or death.
1. Drain water level below all inlets to the pool.
2. Remove drain plugs and strainer cover from strainer housing. (See “Parts Diagram” section of this manual for
pump component locations.)
3. Disconnect pump from wiring (after power has been turned OFF), and piping.
4. Once the pump is fully drained of water, re-install the strainer cover and drain plugs. Store pump in a dry area.

Troubleshooting
9.1.
General Problems
•
Motor Will NOT Start:
1. Check for and correct any improper or loose wiring connections; open switches or relays; tripped circuit
breakers, or blown fuses.
2. With the power disconnected, manually check the rotation of the motor shaft for free movement and lack of
obstruction. Correct if necessary.
•
Motor Shuts OFF:
1. Check for low voltage or power drop at the motor (frequently caused by undersized wiring). Contact a
qualified professional to verify the electrical connections.

USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
Page 13 of 15
VL Series Pump
ISVL1285 Rev B
•
Motor Hums, But Does NOT Start:
1. Impeller jammed with debris. Have a qualified repair professional open the pump and remove the debris.
•
Pump Won't Prime:
1. Empty pump/strainer housing. Make sure the pump/strainer housing is filled with water and the cover o-
ring is clean. Ensure the o-ring is properly seated in the cover o-ring groove. Ensure the o-ring sealing
surface is lubricated with “Jack’s 327” and that the strainer cover is locked firmly in position. Lubricant will
help to create a tighter seal.
2. Loose connections on the suction side. Tighten the union connections.
NOTE
- Any self-priming pump will not prime if there are suction air leaks. Leaks will result in bubbles
emanating from the return fittings on the pool wall.
3. Leaking O-ring or packing glands on valves. Tighten, repair, or replace the valves.
4. Strainer basket or skimmer basket loaded with debris. Remove the strainer housing cover or the skimmer
cover. Clean the basket, and refill the strainer housing with water. Tighten the cover.
5. Suction side clogged. Contact a qualified repair professional. You should have 5” - 6” of vacuum at the
strainer cover (your pool dealer can confirm this with a vacuum gauge). You may be able to check by
removing the skimmer basket and holding an object over the bottom port with the skimmer full and the
pump running. If no suction is felt, check for line blockage.
a. If the pump develops a vacuum, check for a blocked suction line or a dirty strainer basket. An air
leak in the suction piping may be the cause.
b. If the pump does not develop a vacuum and the pump has sufficient “priming water”:
i. Re-check the strainer housing cover and all threaded connections for suction leaks. Check
if all system hose clamps are tight.
ii. Check voltage to ensure that the motor is rotating at full rpm’s.
iii. Open the housing cover and check for clogging or obstruction in suction. Check the
impeller for debris.
iv. Remove and replace the shaft seal only if it is leaking.
•
Low Flow – Generally:
1. Clogged or restricted strainer or suction line. Contact a qualified repair professional.
2. Undersized pool piping. Correct the piping size.
3. Plugged or restricted discharge line of filter, valve partially closed (high gauge reading). Sand filters –
backwash as per manufacturer’s instructions; D.E. filters – backwash as per manufacturer’s instructions;
Cartridge filters – clean or replace the cartridge.
4. Air leak in suction (bubbles issuing from return fittings). Re-tighten the suction and discharge connections
using PTFE tape. Inspect other plumbing connections, and tighten as required.
5. Plugged, restricted, or damaged impeller. Replace the impeller including a new seal assembly.
•
Noisy Pump:
1. Air leak in suction piping, cavitation caused by restricted or undersized suction line or leak at any joint, low
water level in pool, and unrestricted discharge return lines. Correct the suction condition or throttle return
lines, if practical. Holding your hand over the return fitting will sometimes prove this, or by putting in a
smaller eyeball fitting.
2. Vibration due to improper mounting, etc. Mount the pump on a level surface and secure the pump to the
equipment pad.
3. Foreign matter in the pump housing. Loose stones/debris hitting the impeller could be the cause. Clean the
pump housing.
4. Motor bearings noisy from normal wear, rust, overheating, or concentration of chemicals causing seal
damage, which will allow chlorinated water to seep into bearings wiping out the grease causing bearing to
whine. All seal leaks should be replaced at once.
