Isocyanate Hazard
Spraying materials containing isocyanates
creates potentially harmful mists, vapors,
and atomized particulates.
Read material manufacturer’s warnings and
material MSDS to know specific hazards and
precautions related to isocyanates.
Prevent inhalation of isocyanate mists,
vapors, and atomized particulates by providing sufficient ventilation in the work area. If
sufficient ventilation is not available, a supplied-air respirator is required for e v eryone in
the work area.
Isocyanate Hazard
To prevent exposing ISO to moisture:
• Always use a sealed container with a desiccant dryer in the vent, or a nitrogen atmosphere. Never store ISO in an open
container.
• Use moisture-proof hoses specifically
designed for ISO, such as those supplied
with your system.
• Never use reclaimed solvents, which may
contain moisture. Always keep solvent containers closed when not in use.
• Nev er use solvent on one side if it has been
contaminated from the other side.
• Always lubricate threaded parts with Part
217374 ISO pump oil or grease when reassembling.
To prevent contact with isocyanates, appropriate personal protective equipment, including chemically impermeable gloves, boots,
aprons, and goggles, is also required for
everyone in the work area.
Moisture Sensitivity of Isocyanates
Isocyanates (ISO) are catalysts used in two
component foam and polyurea coatings. ISO
will react with moisture (such as humidity) to
form small, hard, abrasive crystals, which
become suspended in the fluid. Eventually a
film will form on the surface and the ISO will
begin to gel, increasing in viscosity. If used,
this partially cured ISO will reduce
performance and the life of all wetted parts.
The amount of film formation and rate
of crystallization varies depending on
the blend of ISO, the humidity, and the
temperature.
312766P 5
Page 6
Isocyanate Hazard
Foam Self-Ignition
Some materials may become self-igniting if
applied too thick. Read material
manufacturer’s warnings and material
MSDS.
Keep Components A and B Separate
CAUTION
To prevent cross-contamination of the
equipment’s wetted parts, never interchange
component A and component B.
Changing Materials
• When changing materials, flush the equipment multiple times to ensure it is thoroughly clean.
• Check with your material manufacturer for
chemical compatibility.
• Some materials use catalyst on the A side,
but some applications may use catalyst on
the B side.
• Epoxies often have amines on the B (catalyst) side. P olyurethanes often have amines
on the B (resin) side.

Installation
A bleed-type master air valve (AD) and a fluid
drain valve (AE) are required in your system,
to help reduce the risk of serious injury,
including splashing fluid in the eyes or on the
skin, and injury from moving parts when you
are adjusting or repairing the pump.
A bleed-type master air valve (AD) is
required in your system to relieve air trapped
between it and the air motor when the valve is
closed (see the WARNING on left). Be sure the
bleed valv e is easily accessible from the pump ,
and is located downstream from the air regulator.
An air line filter (AC) to remove harmful dirt
and moisture from the compressed air supply.
The bleed-type master air valve (AD) relieves
air trapped between this valve and the pump
after the pump is shut off. Trapped air can
cause the pump to cycle unexpectedly and
result in serious injury, including amputation.
Install the valve close to the pump.
The fluid drain valve (AE) helps relieve pressure in the displacement pump, hose, and dispensing valve when shutting off the pump.
Actuating the dispensing valve to relieve pressure may not be sufficient, especially if there
is a clog in the hose or the dispensing valve.
System Accessories
Refer to FIG. 3 and the Accessories on page
24.
To ensure maximum pump perfor-
mance, be sure that all accessories
used are properly sized to meet your
system’s requirements.
A second bleed-type air valve (AD) isolates
the air line accessories for servicing. Locate
upstream from all other air line accessories.
Fluid Line Accessories
A fluid drain valve (AE) is required in your
system to reliev e fluid pressure in the hose and
gun (see the WARNING on left). Install the
drain valve so that it points down and the handle points up when the valve is opened.
Air Line Accessories

Pressure Relief Procedure
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious
injury from splashing or moving parts.
1. Shut off the air to the pump.
2. Close the bleed-type master air valve (AD).
3. Hold a metal part of the dispense valve
firmly to a grounded metal pail. Trigger the
valve to relieve pressure.
4. Open all fluid drain valves in the system,
having a waste container ready to catch
drainage. Leave drain valve(s) open until
you are ready to dispense again.
5. If you suspect the nozzle or hose is
clogged or that pressure has not been fully
relieved after following the steps above,
VERY SLOWLY loosen the hose end coupling to relieve pressure g radually, then
loosen completely. Clear hose or nozzle
obstruction.
Flushing
• Flush at the lo west pressure possible. Chec k connectors f or leaks and
tighten as necessary.
• Flush with a fluid that is compatible
with the fluid being dispensed and
the equipment wetted parts.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious
injury from splashing or moving parts.
