Kettle Temperature Control Calibration
To Check Kettle Temperature Control Calibration:
1. Move Thermolazer
™
to an area with no wind.
2. Turn temperature control to 400° F (204° C).
3. Agitate material for 4 to 5 minutes.
4. After control has reached steady state temperature
and burners do not cycle more than once per min-
ute, insert remote calibrated temperature probe in
material and directly adjacent kettle temperature
control probe.
5. Compare temperature of remote calibrated temper-
ature probe to temperature setting on temperature
control.
6. If the temperature control setting is lower than the
remote calibrated temperature setting on tempera-
ture probe, turn adjusting screw clockwise. Every
1/4 in. turn will change temperature 35° F (19.4° C).
7. If the temperature control setting is higher than the
remote calibrated temperature probe, turn adjusting
screw counterclockwise--every 1/4 in. turn will
change temperature 35° F (19.4° C).
8. Recheck calibration by turning temperature control
to 410° F (210° C) and repeat steps 3-7.
Temperature Control Replacement
When replacing temperature control, keep in mind that
the temperature probe is an integral part of the assem-
bly. Do not make any sharp bends in the capillary tubing.
Bends should be 0.25 in. (0.64 cm) in radius or greater.
Be sure to seal capillary tubing with high temperature
mortar at kettle outlet.
Thermometer Replacement
Thermometer can not be removed from ThermoLazer
™
without damaging thermometer probe. If probe end is
frozen in material, heat material and remove until mate-
rial level is lower than thermometer probe.
