Read the installation section of all system component manuals before
installing your equipment. A thorough understanding of system
components and their requirements will help you install the system safely
and efficiently.
WARNING: Failure to follow these safety procedures can result
in personal injury or death.
SAllow only qualified personnel to install Nordson and auxiliary
equipment. Use only approved equipment. Using unapproved
equipment in an approved system may void agency approvals.
SMake sure all equipment is rated and approved for the environment in
which you are using it.
SFollow all instructions for installing components and accessories.
SInstall all electrical, pneumatic, and hydraulic connections to local
code.
SInstall locking, manual, shutoff valves in the air supply lines to the
system. This allows you to relieve air pressure and lock out the
pneumatic system before undertaking maintenance and repairs.
SInstall a locking disconnect switch or breaker in the service line ahead
of any electrical equipment.
SUse only electrical wire of sufficient gauge and insulation to handle
the rated current demand. All wiring must meet local codes.
SGround all electrically conductive equipment. Ungrounded
conductive equipment can store a static charge which could ignite a
fire or cause an explosion if a hot spark is discharged.
SRoute electrical wiring, air hoses and tubing along a protected path.
Make sure they will not be damaged by moving equipment. Do not
bend electrostatic cables around a radius of less than 6 in. (152 mm).
SInstall safety interlocks and approved, fast-acting fire detection
systems. These shut down the spray system and any flammable
liquid supply if a ventilation or electrical problem occurs, a fire is
detected, or other emergency situation develops.

High-pressure fluids, unless they are safely contained, are extremely
hazardous. A jet of high-pressure fluid can act like a knife or needle,
penetrate skin and muscle, and inject itself into your body. Injected fluids
can cause toxic poisoning.
Do not treat an injection injury as minor. Seek medical care immediately.
Inform the medical staff at the hospital that you have an injection injury
and identify the fluid that was injected. If possible, give the doctor copies
of the MSDS for the injected fluid and for any additives, such as solvents,
that are in the injected fluid.
Nordson recommends that you carry a National Safety Equipment
Manufacturers Association (NSEMA) wallet card to give to emergency
medical staff in the event of an injection injury. These cards are supplied
with the equipment. Additional cards are available free from Nordson
Corporation.
WARNING: Injection hazard. Do not go near a known leak in a
hose or fitting, and stay clear of all dispensing gun nozzles or
orifices. Do not point a film coater at yourself or other
personnel. The high-pressure fluid stream can penetrate skin
and inject fluid into the body causing serious injury or death.
To prevent an injection injury, take some basic safety precautions when
operating your equipment.
SAlways handle film coaters carefully. Do not point a pressurized film
coater at yourself or other personnel.
SNever place hands, fingers, or other parts of your body directly over a
spray nozzle or in front of a leak in a high-pressure system.
SNever “back-flush” the nozzles. Blocking a nozzle causes the
high-pressure fluid to reverse direction and can lead to an injection
injury.
SAlways relieve system pressure before servicing equipment. Trigger
all film coaters and bleed off system pressure.
