provide the force. This prevents the possibility of pulling the screw sockets out of
the housing.
STEP 5 – Install the sensor into the sensor housing. Make sure the elastomeric pad is
between the sensor and the sensor housing concentric rings. Match the alignment pin in
the sensor with the stainless steel pin in the sensor housing. The elastomeric pad can
be installed with either side facing up or down. Rotate the sensor until it locks into the
alignment pin. The gas name/range will be visible through the housing front. To ensure
proper connection between the sensor and housing, tighten the threaded sensor end
cap hand tight – do not over-tighten as this could damage the elastomeric connector or
the sensor housing!
Refer to Figures 8 & 9.
