NORMAL OPERATING PROCEDURES
Daily Start-up Procedure
1.
Check the condition of the Isocyanate lube cup and service as required.
2.
Adjust the packing. The packing nut on the Proportioning Unit is adjustable and will
require tightening when the pump lube is changed.
3.
Check the inlet screens and service as required.
4.
Determine that the chemical system is at the proper temperature as recommended by
the chemical supplier and that the moisture protection system, is in working order.
5.
Turn on the Main Air Supply to the Transfer Pump.
6.
Pressurize the Transfer Pumps and open both A and R-Inlet Supply Valves.
7.
Turn ON the Main Switch. The White pilot light should come on followed by the
Amber pilot light.
8.
Set the Air Pressure Regulator as required.
NOTE:
The standard size 60 pumps have
a material pressure to air pressure
ratio of approximately 16 to 1.
9.
Set the Pump Switch to NORMAL. One of the amber Pump Directional Indicator
Lights should be ON and the Proportioning Pumps should move a short distance and
pressurize.
10.
Connect air to the gun, open the manual valves, and test spray while observing the
chemical pressure gauges on both the up and down strokes. Readjust the regulator as
required.
Daily Shut-Down Procedure
1.
Set the Pump Switch to the RETRACT position.
2.
Trigger the gun off target until the Proportioning Pumps stop in the retracted position
and the Proportioning Pumps pressures bleed off to approximately 500 psi.
IMPORTANT:
It is not a good practice to bleed the pressure to zero. Some pressure
is required to keep the packings operating normally and prevent weepage during
shutdown.
3.
Switch OFF the Main Switch.
4.
Close both Inlet Ball Valves.
5.
Shutdown the chemical supply system as required.
6.
Close both manual valves on the Gun. Shutdown and service the gun as needed.
7.
Turn OFF the Main Air Supply.
