WARNING - To reduce the risk of entrapment hazards:

o When suction outlets are less than a 18” x 23” equivalent, a minimum of two functioning ASME112.19.8 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’) [1 meter] apart, as measured from near point to near point .

o Dual suction outlets shall be placed in such locations and distances to avoid “dual blockage” by a user.

o Dual suction fittings shall not be located on seating areas or on the backrest for such seating areas.
o The maximum system flow rate shall not exceed the flow rating of any listed (per current revision of ASME/ANSI A112.19.8) suction

outlet cover installed.

o Never use the Pool or Spa if any suction outlet component is damaged, broken, cracked, missing, or not securely attached.
o Replace damaged, broken, cracked, missing, or not secure ly attached suction outlet components immediately.
o In addition two or more suction outlets per pump installed in accordance with latest APSP (formally NSPI) Standards and CPSC

guidelines, follow all National, State, and Local codes applicable.

This vacuum release system is designed to prevent body suction entrapment, but not evisceration.

WARNING – Failure to remove pressure test plugs and/or plugs used in winterization of the pool/spa from the suction outlets can

result in an increase potential for suction entrapment as described above.

WARNING – Failure to keep suction outlet components clear of debris, such as leaves, dirt, hair, paper and other material can

result in an increase potential for suction entrapment as described above.

WARNING – Suction outlet components have a finite life, the cover/grate 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 – 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. All drains and suction outlets MUST have properly installed covers, securely attached using the
screws supplied with the covers. If screws are lost, order replacement parts from your supplier.

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 system 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 system pump is running. Before starting system 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) is discharged.

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, 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 air relief valve body is in locked position in filter upper body.

WARNING – Never operate or test the circulation system at more than 40 PSI.

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 of burns.

WARNING – Failure to install according to defined instructions may result in severe personal injury or death.

DEFINITIONS:

General Information:

The VR1000 Vacuum Release System is designed as a pump controller. The system will protect pool and spa equipment from certain
known mechanical failures, such as clogged drains and pipe breakage; which can cause premature pump motor failure. The system
monitors and recognizes a change in pressure and electrical power. When a change occurs, it will shut down the pump, and vent the
suction line. Automatic soft start should provide notice to swimmers or bathers on pump startup. The VR1000 meets the
requirements of ASTM Specification F2387-04. Meets ASME Standard 112.19.17. Meets UL standard 1563 as well as certified to
Can/CSA Std. C27.2 No. 218.1.

The VR1000 system will automatically restart in most instances. Should a manual restart be required, pressing the “OK” button will
restart the system
30 minutes, providing NO protection for sw immers or bathers. DO NOT ALLOW SWIMMERS OR BATHERS IN THE PO OL OR
SPA WHEN THE SYSTEM IS IN “UNPROTECTED” MODE.

For proper installation and to avoid unnecessary service calls, read this manual carefully and completely.

. “Unprotected” Mode can be entered, after restart, by holding “NO” & “OK” buttons. “Unprotected” mode lasts

WARNING – This product should be installed and serviced only by a qualified professional. Failure to install and/or

operate according to defined instructions and/or use of non-Hayward replacement parts will void the warranty.

MECHANICAL MOUNTING INSTRUCTIONS FOR INGROUND POOLS WITHOUT FLOODED SUCTION.

Note: If the installation is for an above ground pool or for flooded suction, the VRX100F assembly is suggested.

The VR1000 is designed to be used on a single pump or a combination of a single pump with a booster pump, on a
common suction line.

1. TURN OFF THE ELECTRICAL POWER AT THE CIRCUIT BREAKER.

2. Remove all check valves from the suction lines of the Pool/Spa system.

WARNING- Check Valves must be removed from the circulation systems. The presence of a check valve used to

carry the water flow within the circulation system has been shown to prolong the high vacuum present at the
drain, even though the drain is protected by a SVRS. For this reason, check valves which carry the water flow
within the circulation system must be removed.

3. For installation of the vacuum sensing tube into the suction line of the pump: (See Page 17 for additional pictures)
a. Locate a straight section of pipe approximately one foot long, as close to the inlet of the pump as practical.
b. On this straight pipe about in the middle, go 45º from the top. (This will minimize the air entrapment in the system

and help keep the system stable.) Drill a 3/8” hole. (See FIG 2)

c. Install the Saddle Gasket on the end of the Saddle fitting. Place the assembly in the drilled hole. Place the saddle

clamp over the saddle fitting. Tighten the Saddle clamp to assure a leak free joint. DO NOT OVERTIGHTEN.

4. Find a location for the VR1000 on a wall, or post, out of the direct sunlight, which will not be flooded, and above the pump.

If the box is mounted below the water level, the vent should be extended to above the water level.

5. Place the Ferrule Nut over the tubing. (See FIG 2) Make sure the tubing bottoms out in the saddle fitting. Holding the

tubing in place, tighten the Ferrule Nut firmly by hand. DO NOT OVERTIGHTEN. Run the 5/16” vacuum tube from the
fitting on the suction line to the fitting on the VR1000 unit. Make sure the vacuum tubing has no kinks and is strain free.
The fitting on the STRATUM™ does not require tooling to install the tubing. Just insert the end of the tubing firmly into the
fitting, a slight pull should not dislodge the tubing.

INITIAL REQUIRED SETTINGS:

1. The VR1000 unit is factory set for 230VAC input. Leave the switch in this “FACTORY SET” position unless a low voltage

error occurs, in which case turn the power off, and move the switch to 115VAC.

2. NOTICE: THE CIRCUIT BOARD AND COMPONENTS MAY BE DAMAGED IF 208/230 VAC IS APPLIED TO

THE BOARD WHEN THE “SWITCH” IS IN THE 115VAC POSITION.

3. The VR1000 is factory set to English, the following three language settings are available by adjusting the dip switches 1, 2 at

the top of the board: A “ON” setting is down and toward the board. Please use a pen or pencil to gently move the switch as
required. See Fig 3

Language 1 2 3 4 5 6 7 8
English OFF OFF 2-Speed Pump Timers Manufacturing Test Booster Pump Specials Pinch Test
Spanish ON OFF
French OFF ON

4. To activate the component test, set Dip Switch 5 to ON. (This should NEVER be done unless directed to do so by Hayward

Technical Service.)

5. For 2 Speed pumps, set Dip Switch 3 to ON. Special wiring required. (See FIG 6)

6. To activate the timer cycle, set Dip Switch 4 to ON.

7. To activate the Booster Pump Timer, Set Dip Switch 6 to ON.

8. Dip Switch 7 is for Welded Contactor settings and High lift situations. (See Page 19) Must be set for flooded suction.

9. Dip Switch 8 performs special functions related to the detection of a pinched vacuum tube. After the pinched tube settings

have been made this switch should be turned to the OFF position to disable the screens (but not the function).

ELECTRICAL CONNECTION INSTRUCTIONS:

1. ASSURE POWER IS DISCONNECTED FROM SOURCE.

2. To install optional contactors the factory-installed wires attached must be connected to the proper terminals on the circuit

board. For a booster pump always use motor relay 3 on the board as shown in FIG. 4.

3. Connect pump to contactor terminals 4 & 8 (See FIG 7). If a booster pump is used, with a pool cleaner, connect this pump to

4 & 8 on a second contactor (Optional Contactor VRX100KIT). The contactor control (2 wires supplied) MUST be
connected onto the board next to the solenoid valve terminals, that is, in motor relay position 3. One reason to connect the
booster pump through this system is to protect the booster pump motor from burn out if the VR1000 were to stop the primary
filter pump. Additionally the timers can then be used to control the timing of the Booster pump.

4. If a two-speed pump is used connect the “Low Speed” to terminals 4 & 8 on a contactor (Optional Contactor VRX100KIT).

The contactor control (2 wires supplied) MUST be connected onto the board in motor relay position 2. NOTE: If the pump

horsepower is greater than 3 HP, the contactors can be used in series with the motor starters. (See Illustration below

FIG 8)

5. Connect a ground wire from the primary electrical panel to the VR1000 and connect the system to the pool bonding system

by an 8AWG (6AWG for Canada) wire. A lug for bonding is provided on the outside/bottom of the enclosure.

6. Connect incoming power to 2&6 on the power relay(s) (See FIG 7). Assure that the earth ground wire connector between the

conductors is secured.

7. (Optional) If a remote stop button is used, remove jumper from terminal pair marked “STOP Switch”. The switch must be a

“locking type “STOP” switch with a normally closed set of contacts in the “UP” position. Install the “STOP” switch across
the terminals where jumper was located. A Steward 28A0640-0A0-1/2 turn ferrite core or equal must be added to the stop
switch cable within 2” of the outside of the STRATUM™ box. (Stop switch can be Square D # KR9RH6 or equivalent
mounted in a rain tight box.)

8. (Optional) If a remote alarm is to be installed, the terminals “Buzzer” are connected to an alarm relay which will supply a

closed contact rated at 115 VAC, 5 amp, when the system alarm trips. External power must be supplied for the alarm to
sound. Can be used with Audible Alarms from Federal Signal Model 350-120-30 or equivalent available from Grainger.

9. The terminal marked “SPARE” when connected to the terminal marked “GROUND” will turn the pump on to “High Speed”

and maintain the “High Speed” mode until these two terminals are disconnected. Thus if a “Manual” override is desired a
maintained contact switch can be used to between these terminals.

10. For Flooded Suction and Pumps located more than 3’ above the pool turn on Dip Switch 7.(See Page 19)

11. Replace the inner barrier and secure with two screws included.

12. Power should be applied to the system while watching the display. Follow the directions on the display. This

operation will confirm the available voltage is suitable for proper operation of the VR system.

NOTICE: THE CIRCUIT BOARD AND COMPONENTS MAY BE DAMAGED IF 208/230VAC IS APPLIED TO THE
BOARD WHEN THE “SWITCH” IS IN THE 115VAC POSITION.

13. Close the electrical enclosure.

14. Apply power to system.
