WARNING

Important Isocyanate (ISO) Information
3A0420ZAF 7
Important Isocyanate (ISO) Information
Isocyanates (ISO) are catalysts used in two component
materials.
Isocyanate Conditions
Keep Components A and B
Separate
Spraying or dispensing fluids that contain isocyanates
creates potentially harmful mists, vapors, and
atomized particulates.
• Read and understand the fluid manufacturer’s
warnings and Safety Data Sheets (SDSs) to know
specific hazards and precautions related to
isocyanates.
• Use of isocyanates involves potentially hazardous
procedures. Do not spray with this equipment
unless you are trained, qualified, and have read
and understood the information in this manual and
in the fluid manufacturer’s application instructions
and SDSs.
• Use of incorrectly maintained or mis-adjusted
equipment may result in improperly cured material.
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 SDSs.
• 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.
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.

Important Isocyanate (ISO) Information
83A0420ZAF
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.
NOTE: The amount of film formation and rate of
crystallization varies depending on the blend of ISO, the
humidity, and the temperature.
Changing Materials
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.
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.
• 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.

Overview
3A0420ZAF 9
Overview
Usage
The XP and XP-h systems are mechanically linked fixed
ratio systems that can mix and spray most
two-component epoxy and urethane protective coatings.
XP systems include: Cart frame, XP pump assembly,
XTR and 35 ft (10.7 m) of supply hose, various options
are specified by the last digit (see page 12 for details).
XP-h systems include: Cart frame, XP-h pump
assembly, XTR and 35 ft (10.7 m) of supply hose (see
pages 13-14 for various other options). The Power Pack
used to power the XP-h motor is sold separately. See
your GH Power Pack manual for details.
When using quick-setting material (less than 10 minute
pot life), the Remote Manifold Heater Block Kit (24Z934)
is recommended for use (see page 12 for models).
The two high pressure fluid pumps are carbide or
stainless steel seat severe duty positive displacement
pumps that displace fluid on both strokes.
Over Pressure Protection
Using an XP system, or components on the system,
not approved for hazardous locations or explosive
atmospheres may result in a fire or explosion hazard.
The XP systems are not approved for use in
hazardous locations unless the base model, all
accessories, all kits, and all wiring meet local, state,
and national codes.
See Systems with Explosion-Proof Heaters on page
25.
Mechanically linked pumps can create excessive fluid
pressure if the full motor force is applied to only one of
the fluid pumps.
•XP Systems Only: Maximum air pressure set point
blow off valves are provided to limit maximum fluid
pressure. Do not remove these valves.
• Color coded automatic over pressure relief valves
are used on cart-mounted systems to dump excess
fluid pressure back to the supply. Never plug these
return hoses. See Fluid Circulation Manifold with
Over Pressure Relief Valves on page 51.
• When using an XP bare pump package to build a
system, use the over pressure relief valves
referenced above.
• Never install individual shut off valves on the “A” and
“B” lines. On cart-mounted systems, common
handles link the fluid control valves.
• A rupture disc is provided on the small side fluid
pump (pumps 145 cc and smaller) as a back-up to
the over pressure relief valve. If the rupture disc ever
opens, do not operate the machine until the over
pressure valve and the rupture disc have been
replaced.
• If changing pump lowers or motor on your system,
use the correct over pressure relief valves from the
chart on page 52.

System Components
* Indicates a customer-supplied component required to
add to Bare Pump Packages (part numbers ending in
zero “0”) to make a complete system.
*Bleed Type Motor Air Valve (MA)
Be sure the valve is easily accessible from the pump
and located downstream from the air regulator (MB).
The two steps below are required in your system to
relieve air trapped between the air motor when the valve
is closed:
1. Open the valve to supply air to the motor.
2. Close the valve to shut off air to the motor, and
bleed any trapped air from the motor.
*Air Pressure Relief Valve (MG)
Automatically opens to relieve air pressure if supplied
pressure exceeds preset limit. Use the correct air
pressure relief valve for the system ratio:
See Models (page 10) for Maximum Regulated Air
Pressure to ensure proper air pressure relief valve
installed.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury
from splashing or moving parts. Use the Bleed Type
Master Air Valve to relieve trapped air.
