1 INTRODUCTION

1.1 Preface

The 751H is an excellent source of clean, dry air for dilution calibrators. It also may be
used as a source of purge air for permeation tube ovens, zero air for ozone generators,
or combustion air for FID analyzers. The 751H has an oil-free and diaphragm-free
pump that pushes air through a pre-cooler and water trap that removes moisture, and
passes the air through a regenerative, heatless dryer for final drying. The pump then
routes the dry air through multiple scrubbers that remove SO2, NO, NO2, O3, H2S, CO,
and Hydrocarbons; the outlet air passes through a final filter to assure a clean, dry,
analytical zero air supply.

The regenerative dryer removes water and produces gas with a dewpoint of less than

-20°C (up to 10 SLPM flow rate) independent of the inlet dewpoint, and assists in the
removal of other gases, greatly increasing the life of the chemical scrubbers. The 751H
is an ideal accessory to the Model T700 Mass Flow Calibrator or Model 702 Single
Point Calibrator as a zero air source for analyzers.

1.2 751H Features

CAUTION

TO AVOID PERSONAL INJURY, ALWAYS USE TWO PERSONS TO
LIFT AND CARRY THE 751H.

CAUTION

TO AVOID PERSONAL INJURY OR DAMAGE TO THE INSTRUMENT,
ALWAYS OPERATE THE 751H WITH THE LID OPEN.

3 GETTING STARTED

This section provides instructions on the proper installation and power up of the
751H. Refer to Figure 4-2 for the instrument layout and Table 2-1 for the
specifications.

NOTE

Due to mounting screws through its case, the 751H is not considered waterproof.

3.1 Unpacking

1. Remove the 751H from its shipping carton.

2. Verify that there is no shipping damage. If there are signs of damage, immediately
advise the shipper, then Teledyne API.

3. Open the lid and check for damage inside.

4. Check the line voltage and frequency label on the instrument to ensure that it
matches the local power source.

3.2 Installation

The basic 751H is a portable, self-contained instrument; there are no installation
instructions other than to ensure adequate support for its weight. However, the
connections must be made to the instrument panel and drain port with the lid open
(see Section 3.4 for connection instructions).
