Warnings

The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. When these symbols appear in the body of this manual, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.

WARNING

WARNINGWARNINGWARNING

ELECTRIC SHOCK HAZARD

The hoses must be grounded. Improper grounding, set-up, or usage of hoses can cause electric shock.

• Turn off and disconnect power before installing or servicing hoses.

• Connect only to grounded power source.

• All electrical wiring must be done by a qualified electrician and comply with all local codes and regulations.

• Never cut or puncture a hose cover.

• Do not expose to rain. Store indoors.

SKIN INJECTION HAZARD

High-pressure fluid from hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.

• Inspect hose before each use for cuts, bulges, kinks or any other damage.

• Replace damaged hose immediately.

• Replace hoses proactively at regular intervals based on your operating conditions.

• Tighten all fluid connections before operating the equipment.

• Keep clear of leaks.

• Do not stop or deflect leaks with your hand, body, glove, or rag.

• Never exceed hose Maximum Pressure or Temperature ratings.

• Only use chemicals that are compatible with hose materials. See Technical Data in this manual. Read Safety Data Sheet (SDS) and fluid and solvent manufacturer’s recommendations.

• Follow the Pressure Relief Procedure when you stop spraying/dispensing and before cleaning, checking, or servicing equipment.

THERMAL EXPANSION HAZARD

Fluids subjected to heat in confined spaces, including hoses, can create a rapid rise in pressure due to the thermal expansion. Over-pressurization can result in equipment rupture and serious injury.

• Open a valve to relieve the fluid expansion during heating.

• Replace hoses proactively at regular intervals based on your operating conditions.

BURN HAZARD

Equipment surfaces and fluid that is heated can become very hot during operation. To avoid severe burns:

• Do not touch hot fluid or equipment.

• Use of incorrectly maintained or mis-adjusted equipment may result in improperly cured material.which could cause off gassing and offensive odors. Equipment must be carefully maintained and adjusted according to instructions in the manual.

• To prevent inhalation of isocyanate mists, vapors and atomized particulates, everyone in the work area must wear appropriate respiratory protection. Always wear a properly fitting respirator, which may include a supplied-air respirator. Ventilate the work area according to instructions in the fluid manufacturer’s SDS.

• Avoid all skin contact with isocyanates. Everyone in the work area must wear chemically impermeable gloves, protective clothing and foot coverings as recommended by the fluid manufacturer and local regulatory authority. Follow all fluid manufacturer recommendations, including those regarding handling of contaminated clothing. After spraying, wash hands and face before eating or drinking.

• Hazard from exposure to isocyanates continues after spraying. Anyone without appropriate personal protective equipment must stay out of the work area during application and after application for the time period specified by the fluid manufacturer. Generally this time period is at least 24 hours.

• Warn others who may enter work area of hazard from exposure to isocyanates. Follow the recommendations of the fluid

manufacturer and local regulatory authority. Posting a placard such as the following outside the work area is recommended:

Important Isocyanate (ISO) Information

Material Self-ignition

Some materials may become self-igniting if applied too thick. Read material manufacturer’s warnings and Safety Data Sheet (SDS).

Keep Components A and B Separate

Cross-contamination can result in cured material in fluid lines which could cause serious injury or damage equipment. To prevent cross-contamination:

• Never interchange component A and component B wetted parts.

• Never use solvent on one side if it has been contaminated from the other side.

NOTE: The amount of film formation and rate of crystallization varies depending on the blend of ISO, the humidity, and the temperature.

Foam Resins with 245 fa Blowing Agents

Some foam blowing agents will froth at temperatures above 90°F (33°C) when not under pressure, especially if agitated. To reduce frothing, minimize preheating in a circulation system.

Changing Materials

NOTICE

Changing the material types used in your equipment requires special attention to avoid equipment damage and downtime.

• When changing materials, flush the equipment multiple times to ensure it is thoroughly clean.

Moisture Sensitivity of Isocyanates

Exposure to moisture (such as humidity) will cause ISO to partially cure, forming small, hard, abrasive crystal that become suspended in the fluid. Eventually a film will form on the surface and the ISO will begin to gel, increasing in viscosity.

NOTICE

Partially cured ISO will reduce performance and the life of all wetted parts.

• Always use a sealed container with a desiccant dryer in the vent, or a nitrogen atmosphere. Never store ISO in an open container.

• Keep the ISO pump wet cup or reservoir (if installed) filled with appropriate lubricant. The lubricant creates a barrier between the ISO and the atmosphere.

• Use only moisture-proof hoses compatible with ISO.

• Never use reclaimed solvents, which may contain moisture. Always keep solvent containers closed when not in use.

• Always lubricate threaded parts with an appropriate lubricant when reassembling.

• Always clean the fluid inlet strainers after flushing.

• Check with your material manufacturer for chemical compatibility.

• When changing between epoxies and urethanes or polyureas, disassemble and clean all fluid components and change hoses. Epoxies often have amines on the B (hardener) side. Polyureas often have amines on the B (resin) side.
