Limited Warranty

Atmospheric Technology (ATEC) warrants to the original purchaser of the Model

8000 Toxic Air Sampler that should it prove defective by reason of improper

workmanship and/or material:

Parts and Labor: For one year on all components from the date of original

purchase, we will repair or replace, at our option, any defective part without

charge for the part. Parts used for replacement are warranted for the

remainder of the original warranty period.

To obtain warranty service, return the unit to ATEC. Shipping expenses are your

responsibility. This WARRANTY DOES NOT COVER damage caused by:

modification, alteration, repair or service of this unit by anyone other than ATEC;

physical abuse to, or misuse of the unit; operation in a manner contrary to the

instructions which accompany the unit; freight damage; or any damage caused by

acts of God such as lightning or fluctuation in electrical power. This warranty also

excludes all costs arising from installation, adjustment of user controls, initial

technical adjustments (set-up) and user-required maintenance including filter

changing.

Any express warranty not provided herein, and any remedy which, but for this

provision, might arise by implication or operation of law, is hereby excluded and

disclaimed. The implied warranties of fitness for any particular purpose are

expressly limited to a term of one year.

1. Introduction

This manual covers the installation, operation and routine maintenance of the ATEC

Model 8000 Automated Sampler. This instrument is a microprocessor controlled

sampler that can be programmed to draw ambient air through cartridges, filters, or

sorbent tubes for specified time periods. The sampler can be configured with

various options to provide up to three independent flow channels. Channel 1 is a

multi-port channel containing 8 ports. Each port can be programmed to sample over

a specific time period. The optional Channels 2 and 3 consist of single ports that

can be activated concurrently or for different time periods than Channel 1. All

channels use separate mass flow controllers (MFC) to regulate the flowrate. The

number of ports on Channel 1 can be increased in multiples of 8 up to a total of 24

ports by adding the Model 80xx expansion modules.

The sampler has the following features:

•Channel 1 ports and Channels 2 and 3 can be programmed to sample on a

specified date (e.g. 06/01/95) for a specified duration.

•All channels are automatically leak checked prior to sampling. If a leak is

detected, a leak check error is recorded for that channel or port.

•Sampling date, start time, stop time, average flowrate, minimum flowrate,

maximum flowrate, total volume sampled, sampling time duration, and error

status are stored for all channels. These data can be displayed on the screen

or transferred to a laptop or PC.Sampling data (i.e. time, flowrate, and

volume) can be logged at a minimum of every 5 minutes. These items are

included in the data transmitted to the PC or laptop.

•The mass flow controllers are auto zeroed prior to sampling.

•A leak check option is provided to manually leak check a port or channel.

3.1.2 Sampler Components

This section describes the general operation and major components of the ATEC

Model 8000 Automated Sampler. Shown here is a schematic diagram of the

sampler. Air enters the sampler to the inlet valve. The inlet valve is normally closed

and allows leak checking of the entire flow system. Out of the inlet valve, the air

passes through the ozone scrubber and filter, and then enters a solenoid manifold.

When a selected port is activated, the air stream passes through the inlet solenoid,

through the cartridge, and returns to the outlet solenoid valve. Two solenoids are
