De-energizing the System

Isolate the system (melter, hoses, guns, and optional devices) from all power sources

before accessing any unprotected high-voltage wiring or connection point.

1. Turn off the equipment and all auxiliary devices connected to the equipment (system).

2. To prevent the equipment from being accidentally energized, lock and tag the disconnect

switch(es) or circuit breaker(s) that provide input electrical power to the equipment and

optional devices.

NOTE: Government regulations and industry standards dictate specific requirements

for the isolation of hazardous energy sources. Refer to the appropriate regulation or

standard.

Disabling the Guns

All electrical or mechanical devices that provide an activation signal to the guns, gun

solenoid valve(s), or the melter pump must be disabled before work can be performed on or

around a gun that is connected to a pressurized system.

1. Turn off or disconnect the gun triggering device (pattern controller, timer, PLC, etc.).

2. Disconnect the input signal wiring to the gun solenoid valve(s).

3. Reduce the air pressure to the gun solenoid valve(s) to zero; then relieve the residual air

pressure between the regulator and the gun.

General Safety Warnings and Cautions

Table 1 contains the general safety warnings and cautions that apply to Nordson hot melt

and cold adhesive equipment. Review the table and carefully read all of the warnings or

cautions that apply to the type of equipment described in this manual.

Equipment types are designated in Table 1 as follows:

HM = Hot melt (melters, hoses, guns, etc.)

PC = Process control

CA = Cold adhesive (dispensing pumps, pressurized container, and guns)

Warnings and Cautions

WARNING! Hazardous vapors! Before processing any

polyurethane reactive (PUR) hot melt or solvent-based

material through a compatible Nordson melter, read and

comply with the material’s MSDS. Ensure that the material’s

processing temperature and flashpoints will not be exceeded

and that all requirements for safe handling, ventilation, first aid,

and personal protective equipment are met. Failure to comply

with MSDS requirements can cause personal injury, including

death.

WARNING! Reactive material! Never clean any aluminum

component or flush Nordson equipment with halogenated

hydrocarbon fluids. Nordson melters and guns contain

aluminum components that may react violently with

halogenated hydrocarbons. The use of halogenated

hydrocarbon compounds in Nordson equipment can cause

personal injury, including death.

HM, CA

WARNING! System pressurized! Relieve system hydraulic

pressure before breaking any hydraulic connection or seal.

Failure to relieve the system hydraulic pressure can result in

the uncontrolled release of hot melt or cold adhesive, causing

personal injury.

WARNING! Molten material! Wear eye or face protection,

clothing that protects exposed skin, and heat-protective gloves

when servicing equipment that contains molten hot melt. Even

when solidified, hot melt can still cause burns. Failure to wear

appropriate personal protective equipment can result in

personal injury.

General Safety Warnings and Cautions (contd)

Equipment

Type

Warnings and Cautions

HM, PC

WARNING! Equipment starts automatically! Remote triggering

devices are used to control automatic hot melt guns. Before

working on or near an operating gun, disable the gun’s

triggering device and remove the air supply to the gun’s

solenoid valve(s). Failure to disable the gun’s triggering device

and remove the supply of air to the solenoid valve(s) can

result in personal injury.

HM, CA, PC

WARNING! Risk of electrocution! Even when switched off and

electrically isolated at the disconnect switch or circuit breaker,

the equipment may still be connected to energized auxiliary

devices. De-energize and electrically isolate all auxiliary

devices before servicing the equipment. Failure to properly

isolate electrical power to auxiliary equipment before servicing

the equipment can result in personal injury, including death.

HM, CA, PC

WARNING! Risk of fire or explosion! Nordson adhesive

equipment is not rated for use in explosive environments and

should not be used with solvent-based adhesives that can

create an explosive atmosphere when processed. Refer to the

MSDS for the adhesive to determine its processing

characteristics and limitations. The use of incompatible

solvent-based adhesives or the improper processing of

solvent-based adhesives can result in personal injury,

including death.

HM, CA, PC

WARNING! Allow only personnel with appropriate training and

experience to operate or service the equipment. The use of

untrained or inexperienced personnel to operate or service the

equipment can result in injury, including death, to themselves

and others and can damage to the equipment.
