Water Chiller System; Exhaust System - Agilent Technologies 700 Series User Manual

Introduction

Water Chiller System

Agilent ICP-OES instruments require a source of cooling water. Refer to the Site
Preparation Guide for compatible water cooling systems.
NOTE The operation manual, mounting and assembly hardware for the cooling system are
included in the water cooler packaging. Care should be exercised to locate all of
these articles before the pack is discarded.
NOTE Pressure regulation is recommended for supplies where the cooling water pressure
may be subject to fluctuations. Pressure regulation is necessary for supplies that
may exceed the maximum permissible pressure of 310 kPa (45 psi).
The instrument is equipped with a water flow sensor, which will stop operation of
the plasma and camera Peltier assembly if the cooling water flow through the
instrument drops below 1.1 L/min (0.3 gpm).
CAUTION
Always ensure the water cooling system is on before igniting the plasma.

Exhaust System

The plasma operates at extremely high temperatures. The ICP-OES instrument
exhaust fumes can be noxious or corrosive.
The exhaust system should be checked regularly to ensure adequate flow. Consult
the Agilent 700 Series ICP-OES Site Prep Guide for the appropriate flow rates.
Hot Surface
WARNING
The external vent may become hot during ICP-OES instrument operation and
remain hot for some time after the instrument has been switched off. Allow
the external vent to cool for at least five minutes before attempting to
remove the exhaust hose. Use heat-resistant gloves.
