7.2.2 Sealant Heating to Slow
Step
Sealant is Heating Slowly
1
With the material level half or less, open the loading lid and inspect the inside
edge of the material tank. Check if there is a buildup of coked or crystallized
sealant along the top half of the material tank.
2
If this is the case you will need to drain out (use up) the rest of the material inside
the tank. When the tank is empty, use an air chisel to remove this built up
material. Remove as much as possible all around the tank including the roof of
the material tank. Remove all the debris from the bottom of the material tank.
This should be done once a year or as needed.
3
Check your level of the heat transfer oil, the mark on the dipstick is for 70°F.
4
Check your records of the last service replacement of the heat transfer oil. If it has
been longer than 500 hours, or one year, you need to change the oil.
5
Many of Crafco, Inc. service centers can perform these service steps for you if you
cannot. Call your local service center to find out if they can.
