Attention
It is important to the system’s electrical reliability
to maintain steady electrical voltage during
shutdown. Failure to follow these procedures
can cause voltage fluctuations that can damage
the equipment and void the warranty.
1. Perform the Pressure Relief Procedure (section 6.4).
2. Turn the block heater ON/OFF switch to OFF (this is the
switch located in the center of the control panel).
3. Turn both hose heater A and B ON/OFF switches to OFF
(these are the switches on either side of the heater block
ON/OFF switch).
4. Switch off the air compressor and any other auxiliary
equipment, if being used.
5. Open the bleed valve on the air compressor in order to
relieve pressure and remove any water that may have
formed in the tank.
6. Turn the Component (A) and Component (B) inlet valve
handles to the closed position (handle should be 90º to
the valve).
7. Shut down the transfer pumps as required.

Perform the following steps on the (A)
Component Pump ONLY unless otherwise
specified. The following must be done in order
to prevent spray material build-up on the (A) side
Component Pump fluid section.
1. Turn the pressure control knob to “MIN PSI” setting in the
yellow zone. The Control Display should say “PRIME”.
2. Press the #1 key on the Control Display. The “CREEP
MODE” screen will now appear.
3. Slowly turn the pressure control knob clockwise to increase
the pressure. The crankshaft/slider assembly will begin to
move very slowly.
4. Wait until the crankshaft/slider starts moving downward.
When it begins its downstroke, turn the Component (A)
PRIME/SPRAY valve to SPRAY.
5. When the crankshaft/slider reaches the bottom, dead-
center of its stroke, turn the pressure control knob fully
counterclockwise. The crankshaft/slider assembly should
stop.
6. Press the cup button 6-8 times to lubricate the piston on
both (A) and (B) Component Pumps.
7. Turn the ON/OFF switches for both Component Pumps to
OFF.
8. Switch the generator OFF. Allow generator dwell time, per
the manufacturer recommendations.
7.2
fluShINg
Flush the system in a well-ventilated area. Do
not turn on hose heaters or block heater when
flushing with flammable solvents.
i
If the new Isocyanate being introduced is
compatible with Polyol, it is not necessary to
flush the (A) side.
1. Flush out the old fluid with new fluid, or flush the old fluid
with a compatible solvents prior to introducing a new
fluid (check with the old fluid manufacturer in order to
determine a compatible flushing solvent).
2. Always use the lowest possible pressure when flushing the
sprayer. Make sure the Component Pump pressure control
knobs are turned as far counterclockwise as possible in the
“MIN PSI” yellow zone.
3. Use only moisture-free solvents when flushing the system.
