IMPORTANT: SAFETY WARNING

Please read these instructions carefully BEFORE this
instrument is installed or maintained.

These transducers are intended for use in industrial com-
pressed air systems only. Ensure that adequate pressure
relief provision is installed if application of system supply
pressure could cause downstream equipment to malfunc-
tion. Installation should be in accordance with local and
national compressed air and instrumentation codes.

Products certified for use in explosionproof/flameproof or
intrinsically safe installations MUST

a) Be installed in accordance with local and national

codes for hazardous area installations.

b) Only be used in situations which comply with the

certification conditions stated in this handbook.

c)

Only be maintained by qualified personnel with
adequate training on hazardous area instrumentation.

Before using these products with fluids other than air or for
nonindustrial applications consult Dresser Masoneilan. Not
intended for use in life support systems.
