Page 16 of 24 STRATUM™ Model VR1000 P/N: ISVR1000TECH Rev: J SPECIAL CONSIDERATIONS • When installing the VR1000 system on a two speed pump that requires suction lift (Self priming), the VR100 must be installed within 10 feet of the pump. This requirement is primarily due to the low vacuums generated by the low speed. • On flooded suction applications, an extension of the vent tube above the water line will provide the venting required. • On flooded suction with a two speed pump, not only is a relatively short vacuum tube (Under 8') required, but the VR1000 Zero Vacuum sensor may need to be reset, if the VR1000 does not stabilize in low speed. This is a special condition in that the head pressure from the flooded suction should be considered in the Zero of the Vacuum sensor. DO NOT disconnect the vacuum tube. Reset the 1st Stab Occurred after this Zero event. • The current system has been tested in flooded suction conditions up to 4' below the surface of the pool. In Flooded suction the maximum measured vacuum must be below 20" Hg when operating. This may require throttling a down stream valve. • 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. ASSEMBLY INSTRUCTIONS SPARE PARTS DISCONNECT POWER FROM THE SOURCE. 1. The solenoid valve (VRX100E) (See Fig 9) is replaced by disconnecting the two wires marked "Solenoid" from the board. Disconnect the tubes from the solenoid valve, by pushing the fitting ring in toward the valve while gently pulling on the tubing. Removing the two screws at the base of the valve will allow the solenoid valve to be removed from the box. To reinstall the solenoid valve the fittings must be removed and replaced in the correct order. Replace TFE tape as needed. Per the labeling on the solenoid valve, the 5/16" tube fitting is installed in Port "A" The 1/4" tube fitting is installed in Port "P". The metric (Gray ring) fitting is installed in Port "R". The short black 5/16" tubing is installed between the bulkhead and the solenoid valve. The small black tubing is a metric tubing and is installed between the board and Port "R" on the solenoid valve. The clear tubing is installed between the "Vent" fitting bulkhead and Port "P" of the solenoid valve. Install the two screws that were removed to hold the solenoid valve in place. Replace the wires in "Solenoid" position on the board. 2. Replacement Pump Contactors: (GLX-RELAY) (See Fig 9 and wiring diagrams) Two screws retain this contactor in place. Aux contactors are installed beside, and in line with the Filter Pump Contactor. Booster Pump contactor must be connected to MR3. The wires should run from the contactor to the board. Power is connected per the diagrams on Page 7. Apply the correct selected label to cover the low voltage side of the contactor. 3. Fitting Kit (VRX100KIT2) (See Fig 2) Includes all parts, except the tubing, shown. It also includes an extension clamp for larger size piping (up to 3"). 4. The Fuse (VRX100H) (See Fig 9) is replaced on the board only if an abnormal power condition has occurred. 5. Tubing Replacement Kit: (VRX100PAK) (See Fig 9) This kit contains three pieces of tube to replace the tubing internally in the box. The board end of the metric black tube is held on by a "Barb" connection. Generally this end of the tube must be carefully slit to remove the tube. Replacement order is covered in Solenoid Valve replacement. 6. Vent Filter: (VRX100F) (See Fig 9) In the event that the system gets repeated S/S failures, this fitting should be inspected to determine it has not been painted or otherwise contaminated. Unscrew the fitting counterclockwise. Replace be screwing on the new filter clockwise. This kit includes fittings to extend the vent tube above the water level. 7. 25' of tubing: (CLX220J25) (See Fig 2) Replacement tubing in case the initial tubing has been damaged. 8. Circuit Board:(VRXPCBA) (See Fig 9) Mark wires with respect to current location on circuit board. Remove tube at connection to solenoid valve by pushing in the ring around the outside of the tubing and gently pulling the tubing out of the fitting. Remove the wires from the green connector strip on the board. Save the jumper from the stop switch connections. Loosen the screws that hold the wires that go from the board to the contactor on the contactor. Loosen the ground screw retaining the green wire from the board to the box. Remove and save the six screws holding the board in the box. Carefully lift the board from the box. It is recommended that the 4mm tubing be replaced when the board is replaced. Carefully replace the board secure with the 6 screws and reconnect all the wires. Do not forget the jumper on the stop connections. CHECK VOLTAGE ON SWITCH MATCHES REQUIREMENT.
