3. INSTALLATION AND OPERATION

3.1 INTRODUCTION

Most of the information and recommendations given here only apply to the Open-Path version
of Searchline Excel. See Chapter 4 for details about installing the Cross-Duct version of
Searchline Excel.
Searchline Excel has been designed, engineered and customer tested to be the most robust,
reliable Open-Path Gas Detector (OPGD) available to date.
The design and technology employed in Searchline Excel makes it far more resistant to the
adverse effects of the operating environment and non-ideal installation engineering than previous
generations of OPGDs.
With careful consideration of the intended operating environment and the installation design,
the installer/operator can maximise the reliability, availability and performance achieved with
Searchline Excel.
Before designing or specifying an installation for Searchline Excel, it is strongly recommended
that the installation design authority reads all of this chapter and considers how the information
and recommendations provided can be applied to their installation(s).
If you have any queries concerning your installation design, contact Zellweger Analytics or your
local agents.
Zellweger Analytics is committed to ensuring that customers achieve reliable operation of their
Searchline Excel Gas Detectors. For this reason, Searchline Excel should only be installed by
fully trained personnel (trained by Zellweger Analytics or a Zellweger Analytics authorised trainer).
This training will provide the installer with a clear understanding of the Searchline Excel product
and the associated accessories and tools. It will also provide familiarity with the installation,
alignment and commissioning procedures, plus installation assessment skills to identify potential
problem areas.
For each installation, an installation check sheet should be completed and returned to ZA or
their agents. Details of this check sheet are given at the end of this chapter.
