NOTE
1. It is recommended that you install an external sample shut off valve to allow control while
accessing or service to the sample chamber.
2. Air purging of upper and lower enclosures is recommended.
3. Each analyzer MUST have its own drain tube vented to atmosphere.
4. The installation of a power circuit breaker is highly recommended.
2.2 Plumbing Connections
Sample inlet, sample return and drain connections are made on the bottom side of the
instrument. The sample inlet and sample return fittings on the bottom of analyzer require ¼” OD
(6 mm OD) flexible tubing. The drain fitting at the bottom of the analyzer requires ⅜” OD (9.6
mm OD) flexible tubing. The air purge inlets require ¼” OD tubing. The air purge supply must be
filtered externally and free of oil and any other particulates.
WARNING
The ⅜” (9.6 mm) DRAIN MUST BE VENTED TO ATMOSPHERE. The sample drain contains
analysis wastes, which include both sample and chemical reagents. Please check with local
authorities concerning proper disposal of waste from this product.
