accessible to all persons operating or servicing equipment.

Qualified Personnel

Equipment owners are responsible for making sure that Nordson equipment

is installed, operated, and serviced by qualified personnel. Qualified

personnel are those employees or contractors who are trained to safely

perform their assigned tasks. They are familiar with all relevant safety rules

and regulations and are physically capable of performing their assigned

tasks.

Intended Use

Use of Nordson equipment in ways other than those described in the

documentation supplied with the equipment may result in injury to persons

or damage to property.

Some examples of unintended use of equipment include

Susing incompatible materials

Smaking unauthorized modifications

Sremoving or bypassing safety guards or interlocks

Susing incompatible or damaged parts

Susing unapproved auxiliary equipment

Soperating equipment in excess of maximum ratings

Regulations and Approvals

Make sure all equipment is rated and approved for the environment in which

it is used. Any approvals obtained for Nordson equipment will be voided if

instructions for installation, operation, and service are not followed.

All phases of equipment installation must comply with all federal, state, and

local codes.

Personal Safety

To prevent injury follow these instructions.

SDo not operate or service equipment unless you are qualified.

SDo not operate equipment unless safety guards, doors, or covers are

intact and automatic interlocks are operating properly. Do not bypass or

disarm any safety devices.

SKeep clear of moving equipment. Before adjusting or servicing any

moving equipment, shut off the power supply and wait until the

equipment comes to a complete stop. Lock out power and secure the

equipment to prevent unexpected movement.

SRelieve (bleed off) hydraulic and pneumatic pressure before adjusting or

servicing pressurized systems or components. Disconnect, lock out,

and tag switches before servicing electrical equipment.

SObtain and read Material Safety Data Sheets (SDS) for all materials

used. Follow the manufacturer’s instructions for safe handling and use

of materials, and use recommended personal protection devices.

STo prevent injury, be aware of less-obvious dangers in the workplace

that often cannot be completely eliminated, such as hot surfaces, sharp

edges, energized electrical circuits, and moving parts that cannot be

enclosed or otherwise guarded for practical reasons.

Fire Safety

To avoid a fire or explosion, follow these instructions.

SDo not smoke, weld, grind, or use open flames where flammable

materials are being used or stored.

SProvide adequate ventilation to prevent dangerous concentrations of

volatile materials or vapors. Refer to local codes or your material SDS

for guidance.

SDo not disconnect live electrical circuits while working with flammable

materials. Shut off power at a disconnect switch first to prevent

sparking.

SKnow where emergency stop buttons, shutoff valves, and fire

extinguishers are located. If a fire starts in a spray booth, immediately

shut off the spray system and exhaust fans.

SClean, maintain, test, and repair equipment according to the instructions

in your equipment documentation.

SUse only replacement parts that are designed for use with original

Grounding

WARNING: Operating faulty electrostatic equipment is hazardous and can

cause electrocution, fire, or explosion. Make resistance checks part of your

periodic maintenance program. If you receive even a slight electrical shock

or notice static sparking or arcing, shut down all electrical or electrostatic

equipment immediately. Do not restart the equipment until the problem has

been identified and corrected.

Grounding inside and around the booth openings must comply with NFPA

requirements for Class II Division 1 or 2 Hazardous Locations. Refer to

NFPA 33, NFPA 70 (NEC articles 500, 502, and 516), and NFPA 77, latest

conditions.

SAll electrically conductive objects in the spray areas shall be electrically

connected to ground with a resistance of not more than 1 meg ohm as

measured with an instrument that applies at least 500 volts to the circuit

being evaluated.

SEquipment to be grounded includes, but is not limited to, the floor of the

spray area, operator platforms, hoppers, photo eye supports, and

blow-off nozzles. Personnel working in the spray area must be

grounded.

SThere is a possible ignition potential from the charged human body.

Personnel standing on a painted surface, such as an operator platform,

or wearing non-conductive shoes, are not grounded. Personnel must

wear shoes with conductive soles or use a ground strap to maintain a

connection to ground when working with or around electrostatic

equipment.

SOperators must maintain skin-to-handle contact between their hand and

the gun handle to prevent shocks while operating manual electrostatic

spray guns. If gloves must be worn, cut away the palm or fingers, wear

electrically conductive gloves, or wear a grounding strap connected to

the gun handle or other true earth ground.

SShut off electrostatic power supplies and ground gun electrodes before

making adjustments or cleaning powder spray guns.

SConnect all disconnected equipment, ground cables, and wires after

servicing equipment.

Action in the Event of a Malfunction

If a system or any equipment in a system malfunctions, shut off the system

immediately and perform the following steps:

SDisconnect and lock out electrical power. Close pneumatic shutoff

valves and relieve pressures.

SIdentify the reason for the malfunction and correct it before restarting the

equipment.

Disposal

Dispose of equipment and materials used in operation and servicing

according to local codes.

standard; an optional 182.8 cm (6-ft) tube-mount gun is available. The

bar-mount gun includes a swivel mount that fits into the end of the optional

gun bar.

The guns are equipped with a 100 kV integral voltage multiplier and

electrode air-wash to prevent powder from collecting on the electrode. The

guns have a straight-through powder path to minimize impact fusion and a

quick-disconnect powder hose connector for quick color change.

The guns can be used with the Nordson iControlrsystem or Encore LT

automatic controllers, which provide electrostatic voltage control, electrode

air-wash air, and powder pump air.

Flat spray nozzles with 2.5 and 4-mm slots are shipped with the guns.

Optional equipment includes:

S8, 12, and 16-meter (26, 39, 52-ft) control cables
