Page 11: Start-Up And First Operation
Start-up and first operation Open the shutoff valve and verify that the Air Valve ■ connections are not leaking; if needed follow the troubleshooting instruction section of this document. Please note that at the first time the valve is filled up some water may exit through its outlet port. -
Page 12: Inspection
Pipeline Draining When a pipeline is drained, a negative differential pressure is created causing atmospheric air to push the float down. The kinetic orifice stays open and air enters the valve chamber, preventing vacuum formation in the pipeline. Inspection The valve does not require any specific maintenance, however a periodical inspection of the seals and flushing of the valve are recommended for removing debris and foreign objects. -
Page 13: Troubleshooting
Valve does not Verify that the operating pressure relief air or does not exceed the valve’s rated allow air intake working pressure. Check and remove foreign objects. Clean the valve’s internal parts, replace if necessary. Consult Bermad if the symptom continues. -

Disassembling and Reassembling the valve 1", ¾" Disassembling the K10 ¾", 1” valve 1. Release the valve’s body (Part #2) by turning it counterclockwise, un-screw and remove it from the valve’s Base (Part #1). Make sure that the valve parts, seated within the cover do not fall out of the cover. - Page 15 Reassembling the K10 ¾", 1” valve 1. Insert the float with the Kinetic Seal on the conduit pin to its place within the valve-cover; make sure that the float freely falls downwards along the conduit pin. 2. Make sure that the valve’s basis O-ring (Part #5) is fully inserted to its groove within the basis.
