Three methods exist for verifying the <br /> relief pressure setting: <br /> 0 The pressure reading can be taken from the CPT <br /> Controller using a tech pod (see "Tech Pod User's <br /> Guide"). <br /> 0 Relief pressure settings may be observed using existing <br /> electronic line-leak detection consoles (see appropriate <br /> operating instruction manual). <br /> 0 Pressure may be observed using a gauge attached at the <br /> impact valve or the line-test port at the pump (see <br /> appropriate operating instruction manual). <br /> Step 4: If the pressure is not correct, adjust the screw again, as <br /> explained in step 2. <br /> Chapter 4:Operation 4-4 ARE260-240 Rev.A ♦ 6197 <br />
