Preparation NOTIFY CUSTOMER INSPECT AREA FLUSH TESTCOCKS (open 4, 3, 2, 1, then close 1, 2, 3, 4) INSTALL FITTINGS INSPECT TEST KIT - CLOSE ALL NEEDLE VALVES

Test #1 - Test Check valve #1 for tightness ATTACH HIGH HOSE TO TESTCOCK 2 ATTACH LOW HOSE TO TESTCOCK 3 OPEN TESTCOCK 3 SLOWLY then OPEN LOW BLEED OPEN TESTCOCK 2 SLOWLY then OPEN HIGH BLEED CLOSE BLEEDS - HIGH FIRST, LOW LAST CLOSE OUTLET SHUT-OFF VALVE OBSERVE CV 1 - (RECORD as CLOSED TIGHT or LEAKING)

Test #2 - Record relief valve opening point OPEN HIGH CONTROL VALVE 1 FULL TURN PLACE HAND UNDER VENT OPEN LOW CONTROL SLIGHTLY - NO MORE THAN 1/4 TURN RECORD RV OPENING > or = 2.0 psi CLOSE LOW CONTROL

Test #3 - Observe whether CV 2 Leaks or closed tight BLEED VENT (BY-PASS) HOSE ATTACH VENT HOSE TO TESTCOCK 4 CLOSE VENT (BY-PASS) CONTROL OPEN TESTCOCK 4 RESET GAUGE - (LOW BLEED) OPEN VENT CONTROL ONE FULL TURN OBSERVE WHETHER RELIEF VALVE VENT DRIPS (If the Relief Valve drips, RESET GAUGE [low bleed] , If Relief Valve drips a second rime, then Check Valve 2 has failed and must be repaired) Close Vent Control ONLY if CV 2 leaks RECORD CV2 as CLOSED TIGHT or LEAKING

Test #4 - Record CV 1 RESET GAUGE - (LOW BLEED) RECORD CV 1 DIFFERENTIAL (3.0 psi > RV opening)

Test #5 - Record Outlet Shutoff Valve CLOSE TESTCOCK 2 – WAIT & CHECK GAUGE FOR LEAKS IN OUTLET SHUTOFF VALVE (RECORD as CLOSED TIGHT or LEAKING) If there is NO flow through the assembly, continue to next test

Test #6 - Record differential pressure across CV 2 CLOSE VENT CONTROL CLOSE TESTCOCKS 3 & 4 REMOVE VENT HOSE FROM TESTCOCK 4 MOVE LOW HOSE TO TESTCOCK 4 MOVE HIGH HOSE TO TESTCOCK 3 OPEN TESTCOCK 4 SLOWLY then OPEN LOW BLEED OPEN TESTCOCK 3 SLOWLY then OPEN HIGH BLEED CLOSE HIGH BLEED FIRST, CLOSE LOW BLEED SLOWLY RECORD CV 2 DIFFERENTIAL > or = 1.0 PSI

Final Steps CLOSE TESTCOCKS - REMOVE ALL EQUIPMENT OPEN ALL NEEDLE VALVES ON TEST KIT OPEN OUTLET SHUT-OFF VALVE SLOWLY
