b. If it is not feasible to soak the regulator while it is attached to a

cylinder, it may be soaked unpressurised – provided that the dust

cap is securely sealed over the inlet, and the second stage purge

buttons are not depressed while the regulator is submerged or

wet.

NOTE: When soaking or rinsing an adjustable model regulator

unpressurised, check to ensure that the second stage inhalation

control knob is turned completely “in” (clockwise) to prevent

moisture from entering the valve and LP hose.

CAUTION: DO NOT loosen the first stage yoke screw, depress

the second stage purge button, or turn out the inhalation

control knob (if present) if the regulator is submerged

unpressurised. Doing so will allow the entrance of moisture,

and will require that the regulator be returned to an

authorised dealer for service.

4. While the regulator is soaking, move the IVS/RVS control switch

(if present) back and forth several times from the “MIN” (–) to the

“MAX” (+) settings. You may also turn the inhalation control knob

slightly back and forth—no more than 4 turns. This action will help

to loosen any salt or mineral deposits that may remain lodged in

the second stage.

5. After the regulator has been properly soaked, it is important to

rinse it vigorously by flushing the first stage ambient chamber

(non-environmentally sealed models only), the second stage

mouthpiece, and the openings in the second stage front cover

with a pressurised stream of water. This will remove any deposits

of salt and minerals that were loosened during soaking. If the

regulator is not pressurised, do not press the purge button

underwater. Moisture may otherwise enter the valves, which will

require that the regulator be returned to an authorised dealer for

service.

6. Wipe the regulator as dry as possible and hang by the first stage

to ensure that all remaining moisture drains from the second

stages.
