CAUTION: If the regulator has been upgraded for use with EAN/ Nitrox, it is important to pressurize and flow test the regulator using only hydrocarbon-free gas. The regulator will otherwise become contaminated with hydrocarbons if normal compressed air is used. Industrial grade compressed Nitrogen is strongly recommended as a less expensive al- ternative to EAN/ Nitrox for the purposes of flow testing.

1.Connect the IP Test Gauge (PN 20-510-100) onto the inlet fitting of the Inline Adjusting Tool (PN 20-500-200), and mate the opposite fitting of the tool onto the inlet fitting of the second stage. Pull back the knurled knob to retract the slotted drive, and tighten the tool clockwise onto the inlet fitting only until finger snug.

NOTE: Check to ensure that the knurled knob of the Inline Adjustment Tool is set to the inner dimple, nearest to the slotted drive, for the S.K.O. second stage. The extended inlet coupling of the SideKick second stage will requre the knurled knob to be set to the outer dimple, in order to pro- vide the deeper reach that is needed for the slotted drive to make contact with the orifice.

2.Install the O-ring(40) onto the post inside the female fitting of the LP hose(39). Mate the female fitting of the LP hose onto the male fitting of the IP Test Gauge, and tighten the swivel nut clockwise until finger snug (see Fig. 20).

3.Install the O-ring(38) onto the male fitting of the LP hose, and install the hose into an intermediate pressure port of a

first stage regulator that has been verified to be properly serviced, with a stable intermediate pressure of 140 (±5) psi . Apply a torque wrench with a b" crow-foot to tighten the fitting to 38 (±2) inch-lbs.

CAUTION: If the second stage has been cleaned and ser- viced for use with EAN/ Nitrox, it is important to connect it with a first stage that has also been cleaned and serviced accordingly, and to use only hydrocarbon-free gas while performing this procedure. Use of standard compressed air will otherwise contaminate the system.
