Unplugging a Clogged Hose (Non-Heated Hose Models)
COILED HOSE
THERMAL REGULATING GATE
Regardless of how you store your hose, the residue tends to settle at the bottom of the coils
overnight. Each day when the unit is started, the hose must be coiled up and placed in the
cabinet during the preheating process, as shown in the picture below. Unless the hose was
cleaned with compressed air, you will probably have enough material remaining in the hose to
require this procedure.
NOTE: Once the Melter is up to operating temperature, the burner typically does not
cycle often enough to get the cabinet to the required temperature to unplug
the hose.
On cold and windy days, it is very important to maintain material flow through the hose at all
times. This requires keeping the material up to temperature and returning the wand to the
access port anytime the wand will be shut off for more than 30 seconds to a minute. If the hose
plugs during sealing operations, one of the following procedures should be followed:
1)
Immediately
remove the sealing tip (if you are using one) and insert the wand into the
access port. With the sealing hose valve and the wand valve both wide open, turn the
pressure valve clockwise to increase the pressure supplied to the hose. Do this until
the engine almost stalls. If this does not work, proceed to another method.
NOTE: Immediately coil the hose inside the cabinet.
