SECTION TWO: Introduction
2.1. Product Description
The GilAir Plus is an advanced personal air sampling pump system available in three
models: a basic model, a datalogging pump (DL) model, and standard temperature and
pressure (STP) model. The STP model corrects the display flow rate and air volume to
standard conditions of temperature and pressure. The STP model can also correct
pump flow rate to keep flow constant with changes in barometric pressure and ambient
temperature.

All models offer constant flow modes and constant pressure control modes. The
Constant Flow Mode holds the set flow constant against changing backpressure within
5% or 3 cc/min whichever is larger. The Constant Pressure Mode holds the pressure
constant when taking samples using constant resistance sampling trains. The constant
pressure (multi-flow) mode allows the air stream to be split into two or more separate
samples so that multiple samples can run at the same time. (See Appendix D for
information on the dual port manifold) Furthermore, all models offer a built-in low
constant flow mode, such that flow rates are attainable from 20 cc/min to 5100 cc/min
without the addition of an external low flow adapter. Operation down to 1 cc/min is
possible in the constant pressure mode. Additionally, all models offer start-stop
programmability. A matrix chart for the available pump models are shown above.
*Note: SmartCalSM Automatic calibration is only available on all pump models when
used with a communications-enabled Dock. The standard Dock that comes with the
basic pump does not have communication capability and will not support the SmartCal
feature.

Gilian GilAir®Plus Air Sampling Pump –Operation Manual
SECTION THREE: Set-Up
3.1. Preparation
The package includes the pump, Dock, Dock power supply, and a line cord. The Dock
serves as the charging base for all models and the communications Dock for the
datalogging and STP models.
Plug the power supply into the Dock and the AC power cord into the power supply.
Connect the AC power cord to mains supply. The supply can accept 100-240 VAC at
50 or 60 Hz.
The pump arrives fully assembled.
IMPORTANT
Before proceeding, you MUST charge the battery to full capacity prior to using the
pump. To charge the pump, place it onto the charging base. The pump’s belt clip
secures the pump in place. Connection is made via contact points on both sides of the
belt clip.
Allow up to five hours for a complete charge. A red LED on the pump indicates
charging in progress; a green LED indicates charged and ready for use. The green
LED will flash during top off charge and is on constantly while on trickle charge. For
more information on charging, see Appendix H.
3.2. Pump Start Up
3.2.1. Power Up
Power pump on by pressing and holding down (about 2 seconds) the button
until the pump turns on.
3.2.2. Startup sequence
As the pump starts it goes through a number of phases that check for correct pump
operation and special situations at startup.
Startup Phases:
1. Power verification: Before starting the voltage from the power source
(battery or DC) must be more than 6.3v. A display screen notifies the user
when the voltage is low and displays the voltage. This typically occurs when
a deeply discharged battery is placed on the Dock during the initial charge
phase to bring the battery to adequate voltage for powering the system.

Sensidyne Document No. 360-0132-01 (Rev T Software version 2.4.0) © 2015 Sensidyne, LP
Page 9
Gilian GilAir® Plus Air Sampling Pump –Operation Manual
2. Dock position determination: When starting up on a Dock, the system
pauses briefly to let the Dock provide the Dock position for use with the PC
App. If no position is available after 45 seconds, a message appears asking
the user to reseat the Dock.
3. Serial number display: The next display shows the product type (Basic,
Datalog or STP), the serial number and the software revision for about 5
seconds.
4. System initialization: During system initialization the memory is read and
checked for validity in the following sections.
Datalog Index:
Datalog is checked for validity and the index is created.
The number displayed is the number of events in the
datalog
Calibration:
The system calibrations are checked for validity.
Point Cal:
Flow calibrations are checked for validity.
System setup:
The block of memory containing the user set parameters is
checked for validity.
Programs:
The user program area is checked for validity.
5. Date Check/Set: If the current system date and time is earlier than the last
date/time stored, this message appears to remind that the date should be
reset.
3.2.3. Power Source Check
When the pump is charging on the Dock and the Dock status is being displayed, the
charge status reported from the Dock is compared to the type of battery that is
installed on the pump. If there is a discrepancy, the pump will signal the user by
flashing the backlight and show a message asking for the pump to be removed.
This is done to prevent the Dock from charging the battery in an inappropriate
manner, which could result in the battery not being charged or being overcharged.
3.2.4. Power Down
Turn power off from any display when the pump is not running by pressing and
holding down the button. After approximately two seconds a power down
display will appear and a five second shutdown sequence will start. If the button is
released before the shutdown sequence is complete the power will not switch off. At
the termination of the shutdown sequence, power is off.
Note: Power cannot be shut down if a sample or program is running.

3.3. Setting the Flow Rate
On the main menu, use the button to move the cursor to Flow Set. Adjust the flow
rate to the desired value using the and buttons. Press and release the
button to confirm the change.
3.4. Power Options
The GilAir Plus comes standard with a rechargeable nickel metal hydride (NiMH) battery
pack. The unit is charged through the Dock that is included with all starter kits.
An optional alkaline battery pack (P/N 783-0013-01-R) is available that allows the use of
over-the-counter AA batteries.
A third option, the DC power pack (783-0014-01-R) allows extended run times with the
pump on the Dock for pumps with firmware versions up to revision 2.4. Pumps that
have firmware version 2.4 or higher are supplied version 3.5 Docks that support running
for extended periods of time while charging on the Dock without the need for the
separate DC power pack.
Note: Do not attempt PC communications with the Dock, when running a sample,
calibrating, or editing pump settings.
Warning: Alkaline batteries, lithium batteries and the DC power pack should only
be used in non-hazardous areas. Intrinsic safety certifications are only valid
when using the rechargeable NiMH battery pack.

Gilian GilAir® Plus Air Sampling Pump –Operation Manual
SECTION FOUR: General Operation
4.1. Overview
The GilAir Plus has the capability of generating and controlling flow over the range of 20
cc/min to 5100 cc/min in two flow ranges, 20-445 cc/min, and 450-5100 cc/min, that are
selectable using a 2 mm or 5/64 inch hex key (provided with the pump). The actual flow
is measured and controlled by the pump’s internal processor. Flow control is provided
directly in the constant flow mode. Pressure control is provided in the constant pressure
control mode, which controls flow indirectly. During a sampling event the flow rate is
displayed in the constant flow mode and backpressure is displayed in the constant
pressure mode. Pump flow is not displayed in the constant pressure mode. The STP
models measure the ambient temperature and pressure and can correct sample
volumes and flows to Standard conditions. Standard temperature and pressure can be
set to desired values. In addition, if enabled, the flow rate can be compensated for
changes in temperature and pressure from the calibration point, holding the calibration
value against altitude induced variability. (Appendix C)
4.2. Connections
Sample media is connected to the inlet port using ¼ inch ID tubing. Adapters that
cause high pressure drop or using smaller diameter tubing may affect the sample flow.
Minimize pressure drop in tubing and fittings and avoid any condition that will exceed
the pump backpressure specifications (see Appendix E). The input port is part of the
input manifold that provides input connection, output connection and contains a filter
that protects the pump from contamination by particulates if operated without an
effective sampling filter. This filter is user replaceable and should be replaced if
discolored, clogged or obstructed in any way.
An output adapter accommodates filling sample containers such as Tedlar or Kynar
sampling bags. Connect the bag fill adapter as shown below. The connection is sealed
with a precision taper and should be inserted only finger tight. The knurled handle will
not seat flush to the surface of the pump and should not be forced. The sample bag
attaches with ¼ inch ID tubing. If the pressure in the bag increases, such as when it is
completely filled, the pressure increase will be shown as increased pump backpressure
and will terminate the event if the backpressure specification is exceeded.

4.4. Menus
The operation of the pump is controlled by entering the menu system and selecting the
menu item that performs the desired function. The menu has submenus that allow
control of related functions. A quick reference menu outline appears in Appendix A.
When the menu is not displayed, the and buttons select among the display
screen options. The display screens are automatically selected by the pump whenever
the mode of operation is changed (example: when an event is started or a fault occurs).
The display screens include the Idle display, the Constant Flow control operating
display, the Constant Pressure control operating display, the Fault display, Program
Status display and STP Display (STP Models only). A description of the data
displayed on each menu screen is contained in the Displays section (Section 4.5. ) of
this manual.
Sampling events: The GilAir Plus accumulates sample data on events. An event is a
sample run. The data for each sample event is stored as the event progresses so that
no data loss is possible. When a sample is started, the event data is cleared to begin
the new event. As the pump samples, the flow is controlled at the event flow rate or
pressure depending on the selected control mode. The event data (time, flow, volume,
backpressure and other information) is stored into nonvolatile memory.
If the pump is paused the event is not terminated. When the event continues, volume
and time accumulation continue in the same event. If the event is stopped, the run data
is available for review (Section 6.10. ) and in the idle screen until another event is
started. The data from the last 16 events is available in the data review menu.
