3) Once you reach the point where the Vac-valve will not open, turn the adjuster nut back 1 complete turn (360 degrees). This setting will usually allow the Vac-Valve to open and provide cooling air into the system if a blockage occurs. Sometimes a turn of 360 degrees may not be sufficient to open the Vac-Valve & allow cooling air to enter – so make minor adjustments moving the nut up & down until you reach the point where the Vac-Valve opens when the air flow is cut off 100%.

2) The Vac-Valve must be set for the size of the motor in order for it to provide the proper protection. To set the Vac-Valve, tighten the adjuster nut to compress the spring to the point where the valve will not open when the air flow is cut off 100%.

4) The Vac-Valve should remain closed if the central vacuum is operating normally. The Vac-Valve should ONLY open when there is insufficient air flow to the central vacuum unit.
