Initial Startup; Fluid Temperature Sensor (Fts) Calibration; Load Fluid With Feed Pumps - Graco Reactor A-20 Operation

Initial Startup

Do not operate Reactor without all covers and shrouds
in place.
Fluid Temperature Sensor (FTS)
Calibration
Calibrate the FTS ONLY at initial startup (the first
time the unit is operated) and any time the hose
length changes.
1. Before turning on the unit, ensure all hoses and
cables are properly connected. To ensure that the
FTS in the hose is at the same temperature as the
heaters, keep heat off and store the hose FTS near
the machine for several minutes.
2. While holding down the temperature unit button
(Fahrenheit - "F" or Celsius - "C") turn the Reactor
main power ON.
3. Hold the temperature unit button until temperature is
shown on the display. The fluid temperature sensor
is now correctly calibrated.

Load Fluid with Feed Pumps

The Reactor is tested with oil at the factory. Flush
out the oil with a compatible solvent before
spraying; see page 13.
1. Check that Setup process is complete; see page 14.
2. Turn on component B agitator, if used.

3. Turn both PRESSURE RELIEF/SPRAY valves (SA,
SB) to SPRAY.

4. Open both fluid valves (FV).

5. Start feed pumps. Do not start proportioner air
motor or pumps.
Always provide two grounded waste containers to
keep component A and component B fluids separate.
6. Hold gun fluid manifold over two grounded waste
containers. Open fluid valves A and B until clean,
air-free fluid comes from valves. Close valves.
