It is extremely important that you read, understand, and follow the safety messages and
regulations carefully before handling the product. They are published to help prevent
these hazards:
• Personal accidents and health problems
• Damage to the product and its surroundings
• Product malfunction
Hazard levels
Hazard level Indication
DANGER:
A hazardous situation which, if not avoided, will result in
death or serious injury
WARNING:
A hazardous situation which, if not avoided, could result
in death or serious injury

Hazard level Indication
CAUTION:
A hazardous situation which, if not avoided, could result
in minor or moderate injury
NOTICE:
Notices are used when there is a risk of equipment
damage or decreased performance, but not personal
injury.
Special symbols
Some hazard categories have specific symbols, as shown in the following table.
Electrical Hazard Permanent-magnet hazard
Electrical Hazard: CAUTION:
User safety
All regulations, codes, and health and safety directives must be observed.
The site
• Observe lockout/tagout procedures before starting work on the product, such as
transportation, installation, maintenance, or service.
• Pay attention to the risks presented by gas and vapors in the work area.
• Always be aware of the area surrounding the equipment, and any hazards posed by
the site or nearby equipment.
Qualified personnel
This product must be installed, operated, and maintained by qualified personnel only.
Protective equipment and safety devices
• Use personal protective equipment as needed. Examples of personal protective
equipment include, but are not limited to, hard hats, safety goggles, protective gloves
and shoes, and breathing equipment.
• Make sure that all safety features on the product are functioning and in use at all times
when the unit is being operated.
Special hazards
Confined spaces
DANGER: Inhalation Hazard
The chamber or tank where the equipment is installed should be treated as a confined
space. Always follow the applicable safety laws, regulations and guidelines for confined
spaces.
Never work alone in a confined space. Before entering the space, check that the following
requirements are complied with:
• The atmosphere contains sufficient oxygen
• The atmosphere contains no explosive or toxic gases
• All energy sources are locked out and tagged out
• Adequate ventilation is in place
• There is a clear path of retreat
Introduction and Safety
Flygt jet aerator JA 112, JA 117, JA 217, JA 317 Installation, Operation, and Maintenance Manual 3

• Monitoring is in place for hazards which can develop after entering the confined
space
• The applicable safety laws, regulations, and guidelines for enclosed spaces are
understood and followed.
Drowning
Spaces that are not fully drained or dry can pose a risk of drowning. It takes relatively little
standing water or other liquid to create a drowning hazard. For example, insufficient
oxygen or the presence of a toxic material can make a worker unconscious, which makes
them vulnerable to drowning if they fall face down into a small pool of water. Never work
alone where there is a risk of drowning.
WARNING:
Bear in mind the risk of drowning.
Biological hazards
The product is designed for use in liquids that can be hazardous to your health. Observe
these rules when you work with the product:
• Make sure that all personnel who may come into contact with biological hazards are
vaccinated against diseases to which they may be exposed.
• Observe strict personal cleanliness.
WARNING: Biological Hazard
Infection risk. Rinse the unit thoroughly with clean water before working on it.
Wash the skin and eyes
Follow these procedures for chemicals or hazardous fluids that have come into
contact with your eyes or your skin:
Condition Action
Chemicals or hazardous fluids in
eyes 1. Hold your eyelids apart forcibly with your fingers.
2. Rinse the eyes with eyewash or running water for at least 15 minutes.
3. Seek medical attention.
Chemicals or hazardous fluids on
skin 1. Remove contaminated clothing.
2. Wash the skin with soap and water for at least 1 minute.
3. Seek medical attention, if necessary.
Protecting the environment
Emissions and waste disposal
Observe the local regulations and codes regarding:
• Reporting of emissions to the appropriate authorities
• Sorting, recycling and disposal of solid or liquid waste
• Clean-up of spills
Exceptional sites
CAUTION: Radiation Hazard
Do NOT send the product to Xylem if it has been exposed to nuclear radiation, unless
Xylem has been informed and appropriate actions have been agreed upon.

Product Description
Jet aerator design
Usage
A submersible, self-aspirating jet aerator that is intended for aerating and mixing of
wastewater. The jet aerator is based on a submersible Flygt pump and a Flygt designed
ejector system.
Pump pressure class
LT – Low head
MT – Medium head
Application limits
For temperatures higher than 40° (104°F), contact your sales and service representative.
Feature Description
Liquid temperature Maximum 40° (104°F)
pH of the pumped liquid 5.5–14
Liquid density Maximum 1100 kg/m³ (9.2 lb per US gallon)
Installation alternatives
P-installation Semi permanent, wet well arrangement with pump installed on two guide bars with
automatic connection to discharge.
The pump is installed on a discharge connection that is fixed to the base of the tank,
with the ejector system mounted on it. This installation is recommended for large jet
aerators, where moving the pump is more practical than moving the ejector system.
S-installation Portable semi permanent, wet well arrangement with hose coupling or flange for
connection to discharge pipeline.
The jet aerator is placed on the bottom of the tank. The jet aerator can be installed
without emptying the tank.
For submergence (H) and height (Z), see the dimensional drawings. For a list of parts, see
chapter List of Parts (page 42).
