3.2 Plumb the instrument C A U T I O N Fire hazard. This product is not designed for use with flammable liquids. C A U T I O N Chemical hazard. If there is a leak in the fluid system, hazardous substances may leak out of the lower enclosure.
Keep the sample lines as short as possible to prevent the accumulation of bottom sediment. The sediment can absorb some of the analyte from the sample and cause low readings. The sediment can later release the analyte and cause high readings. This exchange with the sediment also causes a delayed response when the analyte concentration in the sample increases or decreases.

1. Discard the old containers with remaining contents in compliance with MSDS and regulatory requirements. 2. Install the new bottles. Refer to Install the buffer solution on page 15 and Install the indicator solution on page 15. 8.6 Change the alarm trip point Install the applicable buffer and indicator solution to change the alarm trip point to a different hardness level.
8.11 Replace the fuse D A N G E R Electrocution hazard. Remove power from the instrument before doing maintenance or service activities. D A N G E R Fire hazard. Use the same type and current rating to replace fuses. Remove the two fuses (F1 and F2) and replace them with two new fuses with the same specifications, T, 1.25 A, 250 V.
