INSTALLATION

2. Analyzer Installation

A. Unpacking

Upon arrival, carefully remove the ST-200 aQua electrolyte analyzer and

accessories from shipping containers and place on solid work surface.

Visually inspect ST-200 aQua electrolyte analyzer for any damage

sustained during shipment. If any damage is found, please inform to your

nearest authorized dealer of ST-200 aQua electrolyte analyzer.

B. Component Installation/Replacement

To install or replace ST-200 aQua electrolyte analyzer components, follow

the procedures in this chapter. New ST-200 aQua electrolyte analyzers are

shipped with the fluid control valve and two pump motors.

a. Fluid Control Valve:

Valve is mounted in ST-200 aQua for the supply of Calibrant A, Calibrant

B solutions as per requirement. It controls the flow of Calibrant solutions

by moving the lock pin.

Pinch Valve handling:

For removing or replacement of Valve should be done by using proper

star screw driver if not screw driver will damage the valve holder.

While tightening pinch valve’s screws there should not apply extra

pressure and it should not be super tight. Every time valve should be

handled gently.
