How To Calibrate Your HotShot™ 1500 Cartridge Filler Machine

Once you have put together your HotShot™ Cartridge filler Machine, you’re going to want to calibrate it to the settings you would like for your specific oil and cartridge size.

Calibrating Your Oil Cartridge Filler

You’re going to want to first turn on your HotShot™ system by activating the surge strip you plugged your transformer into. Next, turn on your Anova heating element by pressing the red button located on the front of the display panel. A note, you can switch readings between Fahrenheit and Celsius by holding this button.

You can then add your desired oil into the oil tank and cap it with the lid. The tank is capable of holding up to 1 liter of oil.

Next, you can adjust the system’s operating temperature by moving the thumb wheel located on the Anova, up and down. During your first set up, we recommend heating your Anova to the maximum 170 degrees Fahrenheit and set the onboard heat switch. This is important because the heated actual oil temperature will be anywhere from twenty to thirty degrees lower than the Anova setting depending on the viscosity of the oil used. You can use a heat gun to determine the actual oil temperature then adjust the Anova as necessary to reach your desired oil temperature.

Once the A-10 System is activated, the screen will light up. However, the HotShot™’s screen will not show operational controls until the system and oil are fully heated. If you try operating the system before the system is fully heated a “waiting for heater” signal will display. When operational controls appear on the touchscreen, the A-10 is ready for use.

You can use the touchscreen for all inputs. First, choose the viscosity most similar to your type of oil. There are options of olive oil, glycerine, and honey. Next choose a shot size between three options: .33 grams, .5 grams, and 1 grams. Grams are equal to ml so a .5ml cartridge can be filled with .5 grams and so on. You can also choose a custom setting as well.

You can also adjust the fill speed of the HotShot™, there are 5 speeds to choose from. Finally, enter the final end count of shots you want to disperse. Once your end count is reached, the HotShot™ will stop the flow of oil into the system’s needle. You can press “Hold to reset” to zero out the reading.

Once you have entered in all of the required information we recommend testing the shot output per tick. Different heats, and oil viscosities will lead to slight differences in shot size. We recommend testing by measuring how much is first dispersed, then adjusting your shot size accordingly. The HotShot™’s shot measurements can be changed by .01 increments and will be memorized for the rest of your batch. Once you have the right amount, you’re ready to start filling carts!
