Final Testing Procedures

Fig. 20 - Inline Adjustment Tool w/ IP Gauge

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.
