7. Preparing for use
IMPORTANT
Scubatech / Tecline recommends delivering a demand regulator to an
Authorized Scubatech / Tecline Dealer for connecting accessories such as:
pressure measurement device, medium pressure tubes and second pressure
reduction stages of demand regulators. An Authorized Scubatech / Tecline
Dealer may also answer to questions regarding the issues presented in these
instructions.
For proper preparing a demand regulator for use, the following steps must be
performed:
 equip a demand regulator with a device monitoring gas pressure in a
cylinder/twinset,
 check if a demand regulator kit is complete,
IMPORTANT
Connecting medium pressure hoses to high pressure outputs and using any
connections between medium and high pressure hoses
is forbidden.
 arrange properly medium pressure feeding hoses: buoyancy compensator, dry
suit, etc.
 visually inspect the demand regulator's condition,
 check if all connections and a mouthpiece are assembled properly,
 test for tightness under pressure in the following way:
o insert the mouthpiece of the second-staged demand regulator to your
mouth,
o clog the air inlet to the first-staged demand regulator,
o take a breath through the second-staged demand regulator,
o if taking a breath in such is now impossible the demand regulators is
tight.
IMPORTANT
Before screwing a demand regulator to a diving cylinder/twinset please verify if
the tank valve is unobstructed and clean. Check if there is o-ring in the
pressure reducer’s ferrule and check its condition. If it is damaged or worn out,
it must be obligatorily replaced.
 screw the demand regulator to the diving cylinder's/twinset's seat, lightly
tightening, do not apply too much force,
 slowly open the cylinder's valve (valves),
CAUTION
When opening the cylinder's/twinset's valve, the safety valve of the pressure
gauge should not be directed towards a user or other persons in case of its
malfunctioning.
