CAUTION: The detector tube temperature affects the reading, not ambi-

ent temperature. The thermal ring measures ambient temperature. For

accurate results, ensure the tube has been at ambient temperature for 15

minutes before testing. Then use the temperature displayed on the thermal

ring for temperature correction.

2. Detach the warning label from its backing and afﬁx the warning

label to the pump 3/8” from each side of the engraved lettering.
