TESTING AND ADJUSTMENT OF REGULATOR
CYKLON 5000 (DIVEAIR) Art. No. 2950, 3950
First stage valve:
1. Connect the regulator to the test equipment.
2. Connect the test manometer hose to one of the
low pressure outlets.
3. Open the LP valve (=20 bar)
4. Set the secondary pressure at 11.5 bar, an
intermittently purge the second stage by means
of the purge button. NOTE that the second stage
valve must be fully tight during this test. When
the pressure gauge needle stops at the preset
pressure, a maximum rise in pressure of 1 bar is
allowed before the needle finally stops. Adjust the
pressure to a maximum of 11,5 bar (the maximum
pressure) taking into account any rise in pressure.
If the needle continiues to move to a higher
pressure reading there is a fault in the seal
between 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 the
purge button, check the tightness, and adjust the
pressure to 9 - 10 bar.
6. Close the LP valve and purge it fully.
Second stage valve:
1. Open the LP valve. Adjust the sec. pressure to
11,5-12,0 bar.
2. Check to make sure that the clearance between
the control unit and the low pressure valve is
approximately 1mm. See ill. A. If the clearance is
too small, do not seal the second stage valve. If
the clearance is too large, reduce the flow of air
and the inhalation resistance will increase.
Adjustment of the clearance:
1. Close the LP valve, and empty the regulator
completely by means of the purge button.
2. Unscrew and remove the low pressure hose from
the second stage valve.
3. If the clearance is too small, screw the valve seat
inwards (clockwise) using an 8.5 mm screwdriver.
If the clearance is too large, screw the valve seat
outwards (counterclockwise). NOTE that the
adjustment torque is very sensitive, so you should
screw carefully.The clearance can be checked only
when the secondary pressure is approx 10 bar.
4. Fit the hose and open the LP valve. Check the
clearance 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 mm
screwdriver as shown in ill. B so that the edge of
the hole is opposite the slit in the low pressure
valve. See ill. C. Hold the second stage valve
upright, press the button so that the valve will
give a maximum flow of air, and then release the
button. If the valve continues to blow itself, stop
the air flow using your hand.Turn the ejector
sleeve in the direction of the arrow, see ill. B, and
make a new test using the button. The opening of
the hole should be turned to face upwards as
much as possible, that is, close to the limit where
the valve blows itself.The regulator will then give
a maximum flow of air and the inhalation
resistance is minimal.
3. Close the HP valve and purge fully with the purge
button. Tighten the nut moderately.
