.
Coil heated hoses with a minimum four foot diameter
to avoid kinking and subsequent damage to the
internal electrical wiring.
.
Check and lube top of the fluid section.
Wipe off residual material
and add a tablespoon
of DOP,DBP
Do not bleed fluid pressure from the system.
Extended Shut-Down Procedure
There are many different procedures that are being
followed for extended machine shut down. Because
the system is designed to be compatible with most
urethane formulations, GlasCraft recommends that the
system should be stored with urethanes instead of
solvents, plasticizers, etc. Certain considerations have
to be adhered to when an extended shut-down is being
performed.
The following procedure is for long extended shut-down
periods.
Power should be disconnected and all air regulators
turned down to zero.
1.
Remove side blocks from the gun and relieve pressure
from the system.
2.
Use a suitable solvent to flush the fluid circuits. To
determine the compatibility of solvents with material
being used. Always check with material supplier.
3.
Increase transfer pump pressure until fluid
movement occurs.
If fluid movement does NOT occur @ 100 psi
of air on transfer pumps, increase main pump
pressure until the main proportioner SLOWLY
starts cycling.
4.
Once primary material is flushed from the system,
reduce the main air pressure to zero or flip the
retract switch to the “
retract position
” and trigger
the gun until the pumps are in the down position.
5.
If the solvent used to flush the system also contains
placticizer, ensure that all primary material is flushed
from the system and close the ball valves @ the gun.
.
Leave the pumps in the full down stroke position with
approximately 200-500 psi. on the fluid gauges.
.
If plasticizer is required to chase out solvent, cycle
main pumps until the system is full of plasticizer, then
close valves and leave the pumps in the full down
stroke position with 200-500 psi.
