When servicing the regulator the following parts should bereplaced: See chapter Servicekit.1. All o-rings. Also the ones in the low pressure hose.CLEANING:If corrosion or salt deposits occurs, place all metal parts –concentrated Hempocid* or 15% Hydrochloric acid for about 10minutes. Then, rince the parts thoroughly and blow dry with air.The synthetic parts in the second stage must not be treated withsolvent. They shall be cleaned in freshwater only.*Hempocid = Acid Liquid Detergent Containing phosphoricacid (5 - 10%) and bactericid for desinfectant cleaning.BEFORE INSTALLING CHECKTHE FOLLOWING:1. Diaphragm (24). Check that thesealing surface of the diaphragm iseven. Also check that there are noholes in the diaphragm and that thediaphragm washer is properly fixed inposition.2.

TESTING AND ADJUSTMENT OF REGULATORJETSTREAM Art. No. 2960, 3960First stage valve:1. Connect the regulator to the test equipment.2. Connect the test manometer hose to one of thelow pressure outlets.3. Open the LP valve (=20 bar).4. Set the secondary pressure at 10 bar, andintermittently purge the second stage by meansof the purge button. NOTE that the second stagevalve must be fully tight during this test. Whenthe pressure gauge needle stops at the presetpressure, a maximum rise in pressure of 1 bar isallowed before the needle finally stops. If theneedle continues to move to a higher pressurereading there is a fault in the seal between thevalve seat and piston or the O-ring.5. Close the LP valve, and open the HP valve(=200/300 bar). Purge intermittently with thepurge button, check the tightness, and adjust thepressure to 8.5-9 bar.Second stage valve: Tightness testing of the lowpressure valve withservo valve.1. Close the HP valve and purge fully by means ofthe purge button.2. Remove the low pressure valve from the secondstage housing.3. Place the low pressure valve in the test fixture andscrew on the hose.4. Open the LP valve, push the servo valve’s needlecarefully, and purge a few times. Immerse thevalve below the surface of the water in a specialwater tank and check to make sure that the valveis absolutely tight.5. Move the low pressure valve to the second stagevalve and fit the low pressure valve’s outlet to theguide fitting in the second stage housing. Makesure that the valve is inserted straight to preventthe servo valve from becoming damaged.6. Lubricate the external thread on the second stagehousing and the end of the hose nipple. Screw onthe low pressure hose.Adjustment of the inhalation resistance:1. Open the HP valve.2. Connect the oval connecting pipe on theinhalation resistance gauge to the mouth-pieceon the regulator.3. Test-breathe very carefully. Check the reading ofthe gauge needle, which should rise to 35-40mm/vp and then move back. The turning pointreading equals the inhalation resistance. If thereading is too low, screw the valve tube awayfrom the diaphragm as shown in the illustration. Ifthe reading is too high, screw the valve tubetowards the diaphragm.Checking the purge button:1. Press the purge button. The second stage valveshould now provide a generous supply of air.2. Cover the mouth-piece and press the purgebutton. The second stage valve should thensupply a reduced flow air.

CYKLONTESTING AND ADJUSTMENT OF REGULATORCYKLON 300 Art. No. 2980First stage valve:1. Connect the regulator to the test equipment.2. Connect the test manometer hose to one of thelow pressure outlets.3. Open the LP valve (=20 bar).4. Set the secondary pressure at 11.5 bar, anintermittently purge the second stage by meansof the purge button. NOTE that the second stagevalve must be fully tight during this test. Whenthe pressure gauge needle stops at the presetpressure, a maximum rise in pressure of 1 bar isallowed before the needle finally stops. Adjust thepressure to a maximum of 12.5 bar (the maximumpressure) taking into account any rise in pressure.If the needle continiues to move to a higherpressure reading there is a fault in the sealbetween the valve seat an piston, or the O-ring.5. Close the LP valve, and open the HP valve(=200/300 bar). Purge intermittently with thepurge button, check the tightness, and adjust thepressure to 8.5-11.5 bar.6. Close the LP valve and purge it fully.Second stage valve:1. Open the LP valve. Check the secondary pressure.It should be between 12 and 12.5 bar.2. Check to make sure that the clearance betweenthe control unit and the low pressure valve isapproximately lmm. See ill. A. If the clearance istoo small, do not seal the second stage valve. Ifthe clearance is too large, reduce the flow of airand the inhalation resistance will increase.Adjustment of the clearance:1. Close the LP valve, and empty the regulatorcompletely by means of the purge button.2. Unscrew and remove the low pressure hose fromthe second stage valve.3. If the clearance is toosmall, screw the valve seat inwards (clockwise)using an 8.5 mm screwdriver. If the clearance istoo large, screw the valve seat outwards(counterclockwise). NOTE that the adjustmenttorque is very sensitive, so you should screwcarefully. The clearance can be checked only whenthe secondary pressure is between 10 and 12.5bar.4. Fit the hose and open the LP valve. Check theclearance once again.5. Close the LP valve.Adjustment of ejector sleeve:1. Open the HP valve.2. Turn the ejector sleeve using a 3.5 mmscrewdriver as shown in ill. B so that the edge ofthe hole is opposite the slit in the low pressurevalve. See ill. C. Hold the second stage valveupright, press the button so that the valve willgive a maximum flow of air, and then release thebutton. If the valve continues to blow itself, stopthe air flow using your hand. Turn the ejectorsleeve in the direction of the arrow, see ill. B, andmake a new test using the button. The opening ofthe hole should be turned to face upwards asmuch as possible, that is, close to the limit wherethe valve blows itself. The regulator will then givea maximum flow of airand the inhalationresistance is minimal.3. Close the HP valve and purge fully with the purgebutton. Tighten the nut moderately.

Close the LP valve and purge it fully.Second stage valve:1. Open the LP valve. Adjust the sec. pressure to11,5-12,0 bar.2. Check to make sure that the clearance betweenthe control unit and the low pressure valve isapproximately 1mm. See ill. A. If the clearance istoo small, do not seal the second stage valve. Ifthe clearance is too large, reduce the flow of airand the inhalation resistance will increase.Adjustment of the clearance:1. Close the LP valve, and empty the regulatorcompletely by means of the purge button.2. Unscrew and remove the low pressure hose fromthe second stage valve.3. If the clearance is too small, screw the valve seatinwards (clockwise) using an 8.5 mm screwdriver.If the clearance is too large, screw the valve seatoutwards (counterclockwise). NOTE that theadjustment torque is very sensitive, so you shouldscrew carefully. The clearance can be checked onlywhen the secondary pressure is approx 10 bar.4. Fit the hose and open the LP valve. Check theclearance once again.5. Close the LP valve.Adjustment of ejector sleeve:1. Open the HP valve.2. Turn the ejector sleeve using a 3.5 mmscrewdriver as shown in ill.

Open the LP valve (= 20 bar),.4. Set the secondary pressure at 10 bar, andintermittently purge the second stage by meansof the button. NOTE that the second stage valvemust be fully tight during this test. When thepressure gauge needle stops at the presetpressure, a maximum rise in pressure of I bar isacceptable. If the needle continues to move to ahigher pressure reading there is a fault in the sealbetween the valve seat and the piston or theO-ring.5. Close the LP valve, and open the HP valve(=200/3OObar). Purge intermittently with thepurge button, check the tightness, and adjust thepressure to 8,5-9 bar.Second stage valve: Tightness test of the lowpressure valve and the servo valve.1. Push the servovalve on the low pressure valvecarefully, and purge a few times. Immerse thevalve in a water tank and make sure the valve isabsolutely air tight.Checking and adjustment of the inhalationresistance:1. Connect the oval connecting pipe of the inhalationresistance gauge to the mouth-piece on theregulator.2. Test-breath. Check the reading of the gaugeneedle, which should rise to 38-44 mmvp whenthe valve is opening.3. Adjustment:Remove the cover and the diaphragm.Hold the diaphragm center on the center part andpush an Allen wrench No. 8510 (1,27 mm) in theadjustment screw.If the resistance is too low, turn the screwanticlockwise.If the resistance is too high, turn the screwclockwise.4. Install the diaphragm with the adjustment screwto the right position and the cover. Test againfrom pos. 1.Checking the purge button:1. Press the purge button. The second stage valveshould now provide a generous supply of air.2. Cover the mouth-piece and press the purgebutton. The second stage valve should nowsupply a reduced air flow.
