Adding Additional Salt to Make Final Volume
As noted previously, as the TAP control heats the salts, the salts will become molten. Once molten, remaining salts needed to make the final volume can be added to
the salt pot. We recommend adding additional salts in 1 to 2 cup volumes and allowing them to liquefy before adding additional. Continue adding these small
amounts until the salt pot has reached its final volume. Final volume again should not exceed chamber depth. It can be less, just not more.
Switching to the Immersion Thermocouple
Once the salts are molten and the level begins to rise you may insert the Immersion Thermocouple into the salt bath and control from that thermocouple. Be sure at
least 1” of the Immersion thermocouple is immersed within the molten salt. If it isn’t yet, continue to add salts until it does and then proceed with this step.
As noted in the cautions and use data, be sure that any item you place into the molten salt is absolutely clean. This includes the Immersion thermocouple as well.
Immersion Thermocouple placed within the salt pot and held with mount
Once the Immersion thermocouple is inserted into the salt bath, press the “Probe” key on the TAP control and then press the “Immersion” key. This action
causes the TAP control to now control the heating process via the Immersion thermocouple which is the actual temperature of the molten salts, and that’s
what we want.
Press the “PROBE” key to select Active Thermocouple
A dialogue box appears, press “Immersion” to select the
Immersion Thermocouple. The dialogue box disappears and
you are now controlling from the Immersion thermocouple.
