Pressure Relief
Procedure
1.
If your setup uses the optional shutoff valves,
rotate the handles to the “open” position.
2. Shut down chemical pumps.
3. Drain air pressure from the A and B side chemical
tanks.
4. After tank air pressure is at zero, close the A and B
tank outlet valves.
5. Verify pressures read zero on chemical pressure
gauges.
6. Turn off hydraulic power pack.
7. Bleed hydraulic pressure via dump valve on power
pack.
8. Verify pressures read zero on hydraulic pressure
gauges.
Shutdown
2. Perform any required maintenance. See
on page 16.
3.
If system will not be in use for longer than two
weeks,
the A and B chemical tanks must have
10 psi of dry air pressure.
4.
If the gun will not be used for longer than four
weeks,
flush the gun.
NOTICE
Air must be dry. Moist air will react with isocyanate
and cause crystallization resulting in significant
component damage.
