If the GilAir Plus pump comes into contact with a destructive substance(s) it is the
responsibility of the user to take suitable precautions that prevent the pump from being
adversely affected, thus ensuring that the Intrinsic Safety protection is not
compromised. Destructive substances include acidic liquids or gases that may attack
metals, solvents that may affect polymeric materials, other solvents, or corrosives.
Suitable precautions are regular checks as part of routine inspections and establishing
from material data sheets that chemicals known to be present do not have an adverse
effect on the material of the pump (polycarbonate, polyester, silicone, Buna-N,
Neoprene, Stainless steel, brass and epoxy).
DO NOT operate with a dirty or blocked inlet filter or kinked tubing. Pump failure or
faulting may result.

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.

All models offer constant flow modes and constant pressure control modes. The
Constant Flow Mode holds the set flow constant against changing back pressures 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. Furthermore, all models
offer a built-in low flow mode, such that flow rates are attainable from 1 cc/min to 5000
cc/min without the addition of an external low flow adapter. Additionally, all models offer
start-stop programmability. A matrix chart for the available pump models is shown
above.
*Note: SmartCalSM Automatic calibration is only available on all pump models when
used with a communications-enabled Dock. The standard dock/charger 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 100-240vAC, at 50
or 60 Hz.
The pump arrives fully assembled.
Charge battery to full capacity before 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 three and one-half 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.
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. Idle Mode
Pump will enter idle mode for five seconds then display the main menu.
3.2.3. 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
window 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.

Page 10
Gilian GilAir®Plus Air Sampling Pump –Operation Manual
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. 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 alkaline or lithium batteries. A third option, the DC power adapter
(783-0014-01-R) allows extended run times with the pump on the dock.
Note: Do not attempt PC communications with the Dock, when running a sample using
the DC power adapter or alkaline cell battery pack.
Warning: Alkaline batteries, lithium batteries and the DC power adapter 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 1
cc/min to 5000 cc/min in two flow ranges, 1-449 cc/min, and 450-5000 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 back pressure is displayed in the constant
pressure mode. Pump flow is not displayed in the constant pressure mode.
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 back pressure 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 (included with pump kits) accommodates filling sample containers
such as Tedlar or Kynar sampling bags. Connect the bag fill adapter and the sample
bag using low-resistance tubing. If the pressure in the bag increases, such as when it is
completely filled, the pressure increase will be shown as increased pump back pressure
and will terminate the event if the back pressure 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 review 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 6.11. ) and in the idle screen until another event is
started. The data from the last 16 events is available in the data review menu.
