Circulation and Pumping Procedure
Sealing Procedure
During the circulation and sealing operations, it is important to monitor the material tempera-
ture gauge as the material circulates through the plumbing system. The material should not
exceed the manufacturer's recommended pouring temperature.
Refer to Diagram 1
When sufficient material has melted (approximately 4-6 inches liquid on tank bottom) or gone
through the heating cycle required for liquid type sealants, begin circulation procedure.
1)
Close air cleanout valve (if equipped) and sealing hose valve (A).
2)
Turn pressure valve (B) counterclockwise to the full "decrease" position.
3)
Rotate the material pump drive knob (C) counterclockwise to the normal flow position.
If the pump will not rotate, return knob to neutral and continue heating until pump will
rotate.
4)
Open tank outlet valve (D).
5)
When the material is flowing evenly through the bypass and is at the recommended
pouring temperature, stop the material pump drive by returning knob to the neutral
position.
6)
Close thermal regulating gate if still open, and on propane units open stack diverter.
7)
Remove sealing tip, open wand valve (F). Place the wand into the access port.
8)
Restart the material pump and allow the material to circulate. Turn pressure valve
clockwise, "increase" until the engine begins to lug.
9)
Open sealing hose valve to the full "open" position.
10)
When the material is flowing freely through the sealing hose and wand, place material
pump drive knob to the neutral position to stop pump.
11)
Turn wand valve "off".
12)
Remove the wand from the access port and quickly install the appropriate sealing tip.
Immediately return the wand to the access port.
13)
Open wand valve and start material pump drive by rotating knob counterclockwise.
