D141B038U01). Sealing is only possible if the flowmetersensor is installed horizontally.Observe the following instructions during work activity:Warning - General risks!The sealing compound is toxic. Observe all relevant safety measures.Risk notes: R20, R36/37/38, R42/43Harmful by inhalation. Avoid direct skin contact. Irritating to eyes.Safety advice: P4, S23-A, S24/25, S26, S37, S38Wear suitable protective gloves and ensure sufficient ventilation.Follow the instructions that are provided by the manufacturer prior to starting anypreparations.Preparation• Complete the installation before beginning sealing activities in order avoid moisturepenetration. Before starting, check all the connections for correct fitting and stability.• Do not overfill the terminal box. Keep the sealing compound away from the O-ring and theseal/groove (see Fig. 34).• Prevent the sealing compound from penetrating a thermowell if an NPT ½" thread is used.Procedure1. Cut open the protective enclosure of the sealing compound (see packaging).2. Open the connection clamp between the hardener and the sealing compound.3. Knead both components thoroughly until a good mix is reached.4. Cut open the bag at a corner. Perform work activity within 30 minutes.5. Carefully fill the terminal box with sealing compound until the connecting cable is covered.6. Wait a few hours before closing the cover in order to allow the compound to dry, and torelease any possible gas.7.
