System Components

System Components
* Indicates a customer-supplied component required to add to OEM Packages (part numbers ending in zero "0") to
make a complete system.

*XP-hf Motor Air Valve (CA)

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.
Be sure the valve is easily accessible from the pump
and located downstream from the air regulator (CB).
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.
*XP-hf Motor Air Pressure Relief
Valve (CG)
Automatically opens to relieve air pressure if supplied
pressure exceeds preset limit. Use the correct air
pressure relief valve for the system ratio:

*Main Air Filter (CC)

Removes harmful dirt from compressed air supply. A
minimum 40 micron filter is used.

*XP-hf Motor Air Regulator (CB)

Adjusts air pressure to the motor and fluid outlet
pressure of pump. Locate the air regulator close to the
pump. Read air pressure on the gauge.

Fluid Line Components

• *Recirculation Manifold (AA): Controls circulation
and pump priming.
• *Mix Manifold (AB): Combines A and B fluid into
one fluid line.
• *Recirculation Handle (AC): Directs fluid flow for
circulation or mixing. Move to open position to
relieve fluid pressure, prime pumps, and circulate
material in hoppers. Move to closed position to
spray mixed material.
• *Dual Shutoff Handle (AE): Controls A and B fluid
flow for mixing and dispensing. Close before
flushing.
• *Solvent Flush Valve (AD): Controls solvent flow
to the mix manifold, hose, and spray gun.
• *Static mixer/gun hose kit (W): Thoroughly mixes
the two fluids and delivers the mixed fluid to the
spray gun. Includes static mixer and hoses to the
spray gun.
• Viscon HF Fluid Heaters (F): Heats the resin and
hardener before mixing. Improves the chemical
reaction and lowers viscosity to improve the spray
pattern.
• Solvent Flush Pump (BA): Flushes the mix
manifold. Includes a solvent pump, mounting
hardware, and solvent supply hose.
