1 SAFETY
1.1 Safety Practices
This document describes the general safety practices and precautions that must be
observed when operating the Airow Monitor.
This advice is intended to supplement, not supersede, the normal safety codes in the
user’s country. The information provided does not cover every safety procedure that
should be followed. Ultimately, maintenance of a safe laboratory environment is the
responsibility of the user and the user’s organisation.
Please consult all documentation supplied with the Airow Monitor before starting
to work. Carefully read the safety information in this document and in the other
documentation supplied. When setting up the equipment or performing analysis or
maintenance procedures, strictly follow the instructions provided.
1.2 Warning Notices
Within this User Guide WARNINGS are used to highlight information or instructions
that must be followed in order to avoid personal injury to yourself or other people in
the vicinity, eg. switch o the mains voltage before any maintenance.
WARNINGS appear as below:
1.3 Precautions
The following precautions must be observed when using the Airow Monitor
and associated systems:
• Be sure that the voltage of the Airow Monitor equipment corresponds to the
voltage available where it is to be installed.
• Never remove the side or back panels of the Airow Monitor without rst shutting
down the equipment and disconnecting the power supply.

Version 01 / p.6
AFA1000/2 MK2 Airflow Monitor
Installation & Operating Manual
1.4 General Operating Conditions
The Airow Monitor and equipment have been designed and tested in
accordance with the safety requirements of the International Electrotechnical
Commission (IEC). The Airow Monitor conforms to IEC61010-1 (Safety Requirements
for electrical equipment for measurement, control and laboratory use) as it applies
to IEC Class 1 (earthed) appliances, and therefore meets the requirements of EC
directive 73/23/EEC.
If possible, avoid any adjustment, maintenance or repair to the eqipment whilst
covers are open or it is operative. However, if any adjustment, maintenance or repair
is necessary while the covers are open, this must be done by a skilled person who is
aware of the hazards involved.
Whenever circumstances arise that mean an Airow Monitor may be unsafe,
make it inoperative. In particular, an Airow Monitor may be unsafe if it:
• Shows visible damage.
• Fails to perform correctly.
• Has been subjected to severe transport stresses.
• Has been subjected to prolonged storage in unfavorable conditions.
1.5 Environmental Conditions
The Airow Monitor should only be used under the following conditions:
• Indoors.
• In ambient temperatures between 5°C and 40°C.
• With relative humidity below 80% for temperatures up to 31°C, decreasing linearly
to 50% relative humidity at 40°C.
• Electrical supply uctuations not exceeding +10% of the nominal voltage.

Version 01 / p.7
AFA1000/2 MK2 Airflow Monitor
Installation & Operating Manual
1.6 Electrical Safety
The Airow Monitor and associated equipment are designed to protect the user from
potential electrical hazards. This section describes some recommended electrical safety
practices.
The Airow Monitor and associated equipment must be correctly connected to a suitable
electrical supply. The supply must have a correctly installed protective conductor (earth
or ground) and must be installed and checked by a qualied electrician before initial
power up.
When working with the Airow Monitor System:
• Connect the equipment to a correctly installed mains power outlet that has a protective
conductor connection.
• Do not operate the equipment with any covers or internal parts removed.
• Disconnect the equipment from all live voltage sources before opening it to make any
adjustments, replacements, maintenance or repair. If the opened equipment must be
operated for further adjustment, maintenance or repair, this must only be done by a
supplier’s Service Engineer.
If it is possible that the equipment is no longer electrically safe for use, make the
equipment inoperative and secure it against any unauthorised or unintentional operation.
The electrical safety of the equipment is likely to be impaired if:
• It has any signs of visible damage.
• If it has been subjected to prolonged storage in unfavourable conditions.
• If it has been subjected to severe stress during transportation.
Any interruption of the protective conductor inside or outside
theAirowMonitorSystem,ordisconnectionoftheprotective
conductor terminal is likely to make the equipment dangerous.
Intentional interruption of the protective conductor is prohibited.

Installation & Operating Manual
1.7 Electrical Protection
Observe the following electrical protection precautions:
• Insulation: Class I rating for external circuits. Only connect equipment that meets
the requirements of IEC 61010-1, IEC 60950 or equivalent standards.
• Installation Category: The equipment is able to withstand transient over-voltages
typically present on the mains supply. The normal level of transient over-voltages is
impulse withstand (overvoltage) Category II of IEC 60364-4-443.
• Pollution Degree 2: Normally only non-conductive pollution occurs. Occasionally,
however, temporary conductivity caused by condensation must be expected.
1.8 EMC Compliance
EC Directive
The Airow Monitor System is designed and tested to meet the requirements of
the EC directive 89/336/EEC and 93/68/EEC and complies with the EMC standard
EN61326 (EMC standard for electrical equipment for measurement, control and
laboratory use) and EN55011 (ISM) Class A (RF emissions).
FCC Rules and Regulations
The Airow Monitor System is classied as a digital device used exclusively as
industrial, commercial or medical test equipment. It is exempt from the technical
standards specied in Part 15 of the FCC Rules and Regulations based on Section
15.103 (c).
1.9 Warning Labels
Warning labels attached to the equipment draw attention to specic hazards - refer
to this guide and other documentation provided with the equipment for more details
concerning potential hazards and any precautions or other actions that must be
taken.

2.2 Display Features
TheAirowMonitordisplayhasthefollowingfeatures:
The digital display is a backlit, full colour high resolution graphic unit with a visual display area of
approx 45 x 34mm. The display operates through the software allowing the generation of gures,
wording and icons. The display background colour can be provided as either Blue or Black.
The display shows the fume cupboard face velocity in m/sec or fpm when enabled or the alternative
with no velocity reading but showing AIR FAIL / AIR SAFE as continuous display. All of the above are
congurable via the alarm key pad.
The displayed face velocity colour will change when in an alarm condition:-
Air Safe = White / Low or High Air Alarm = Red / Warning Air Alarm = Amber.
An ‘event time line’ segmented into 60 x 1 minute segments will scroll across the display (when
enabled) .This takes the form of a graphical scale ranged over 0-1.00 m/sec that will progress from the
right hand side to the left hand side of the screen – representing the airow value at each segment.
The segment colour will change if the value is in the range of an airow alarm:-
Air Safe = White / Low or High Air Alarm = Red / Warning Air Alarm = Amber.
The alternative to the event time line is a dynamic ‘bar graph’ representing the airow velocity.
The display shows an up or down arrow Icon in the bottom right hand corner of the screen when an
input function is set to Hi / Lo (2 speed operation). The Up arrow indicates High speed and the Down
arrow indicates Low speed.
The display shows a Horn icon (with line through it) when the audible alarm is in the Muted condition
The display backlight will dim to a xed low level when certain functions are active to save energy:-
FanO- display backlight reduces until Fan On is selected.
Backlight will resume to normal level whilst Set Up or Diagnostics menus are accessed.
Setback Input is active - display backlight reduces until input is not active.
Backlight will resume to normal level whilst Set Up or Diagnostics menus are accessed.

2.6 Audible Alarm Sounder
The AFA1000/2 has an audible sounder with local or remote mute facility. The
audible alarm can be permanently disabled in the cal cong menu.
The audible alarm is muted if Fan O is selected on pushbutton 1 or when the Mute,
Setback or Alarm Disable input functions are active.
The display will show a Mute Icon in the bottom left hand side of the screen
whenever the audible alarm is muted or disabled.
