Fire hazard. This product is not designed for use with flammable
liquids.
Install the instrument:
• As near the sample source as possible to decrease analysis delay
• In a clean, dry, well ventilated, temperature controlled location with
minimum vibration that does not receive direct exposure to sunlight
• In an environmental enclosure that supplies protection from
precipitation and direct sunlight, good ventilation and temperature
control if installed outdoors
• In a location where the power switch and power cord are visible and
easily accessible
• In a location where there is sufficient clearance around it to make
plumbing and electrical connections
Mechanical installation
Attach the instrument to a wall
Attach the instrument upright and level on a flat, vertical surface. Refer
to the illustrated steps in

The sample flow must always be against gravity to prevent bubbles from
being trapped in the sensor. Flow is from the bottom to the top of the
sensor subassembly.
Note: The instrument can be attached to an existing panel. Install screws directly
to the rear panel or use the mounting hardware supplied.
