Controls and Indicators
Power Switch
Powers the system on and off.
Motor/Pump Control Function Knob
Use the knob to select desired function.
STATUS Indicator
Indicates the system status, including power and error
codes.
• Indicator steady on: power switch is turned on.
• Indicator blinking: If an error occurs, the status
indicator light will blink one to seven times to
indicate a specific status code, pause, and then
repeat. The following table provides a brief
description of each status code. For more detailed
information and corrective action, see Status
Codes on page 21.
Table 1: Status Codes
(also located on the front of the Reactor)
NOTE: The default is to shut down if a status code
indication occurs. Codes 1 and 2 may be set to disable
automatic shutdown if desired; see page 22. You cannot
set the other codes.

Setup
Location
• The system should always be used on a level
surface.
• Do not expose the system to rain.
Electrical Requirements
• Required power source: single dedicated circuit that
is rated at a minimum of 15A.
NOTE: Cords must be 3-conductor grounded, rated for
your environment.
• Power cord connector (120V):
One NEMA 5-15T
• Extension cord requirements:
Grounding
System: grounded through power cord.
Generator (if used): follow your local code and
manufacturer’s recommendations. Start and stop the
generator with power cord(s) disconnected.
Spray gun:ground through connection to a properly
grounded fluid hose and system.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive
surface, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray gun
firmly to the side of a grounded metal pail, then trigger
the gun.
Required Wire Size
Up to 50 ft (15 m) Up to 100 ft (30 m)
AWG 14 AWG 12
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.

Connect Fluid Hoses
Connect the fluid supply hoses to outlet hose
connections (FIG. 3). Red hoses for component A (ISO),
blue for component B (RES). Fittings are sized to
prevent connection errors. Connect the other end of
hoses to A and B inputs of the gun.
Connect Gun to Air Hose
(Air-Operated Guns Only)
Connect the gun air hose to the gun air input and to the
air filter outlet. If you are using more than one hose
bundle, join the air hoses with the nipple provided with
the hose bundle.
Connect Main Air Supply
The system requires 4 scfm (0.112 m3/min) compressed
airfor the air operated spray guns to work correctly.
Connect the main air supply to the quick disconnect
fitting on the unit. The air supply hose must be at least
5/16 in. (8 mm) ID up to 50 ft (15 m) or 3/8 in. (10 mm)
ID up to 100 ft (30 m).
Flush Before Using Equipment
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid
contaminating your fluid with oil, flush the equipment
with a compatible solvent before using the equipment.
See Flushing, page 19.
NOTICE
To prevent pressure fluctuations and equipment
damage, only operate equipment with fluid supply
hoses longer than 25 ft.

Fill Wet-cups
Keep the felt washers in the pump wet-cups saturated
with ISO pump oil. The lubricant creates a barrier
between the ISO and the atmosphere.
Fill wet-cups through the slots in the plate, or remove a
screw and swing the plate to the side.
The pump rod and connecting rod move during
operation. Moving parts can cause serious injury such
as pinching or amputation. Keep hands and fingers
away from the wet-cup during operation. Shut off
power before filling the wet-cup.
