Tack Tank- Low Level Shut Down (optional)
This system incorporates a float in the tack tank that is hooked to a switch. When the tack
material reaches a level several inches above the flues, the burner or heater will be shut off to
prevent equipment damage. This eliminates the need of someone continuously monitoring
the level in the tack tank. The function of the low level shut down must be checked on a daily
basis by the equipment operator and the calibration should be checked every six months and
adjusted as necessary by a qualified technician.
1. Operational Check (daily)
a. Ignite burner following the appropriate instructions.
b. Manually trip the low level shut down switch located on the float shaft. This should
cause the burner to shut down. If the burner does not respond correctly, contact a
qualified service technician or call the manufacturer.
2. Calibration Check (every 6 months)
a. Verify that the burner shuts down when the product reaches a level no less than 4"
above the flues.
b. Adjust by loosening the set screw on the switch cam and rotating the cam as neces-
sary.
c. Tighten set screw and verify adjustment.
