Caution: Electrostatic discharge (ESD) precautions need to be taken prior to removing the fascia from
the detector. A wrist strap must be connected to the case of the detector (Figure 1-1).
Attention : Les precausions contre le decharge electrostatique dois etre respecter avant d’ouvrir le panneau
du detecteur. Un bracelet doit être raccordé au panneau du détecteur (Figure 7-7).
Ensure the area around the Sampling Module is clear of dirt and debris prior to replacement.
Care must be taken during Sampling Module replacement. The Sampling Module must be correctly seated in
order for a correct seal to be established between the Sampling Module and the rest of the detector. It is
essential to ensure that the rubber seal on the underside of the Sampling Module is correctly in place.
