1.  Pre-Heating Preparation

a.  Ensure Proper Ventilation

•      Make sure the enclosure has at least one intake vent at the bottom for air to enter and one exhaust vent (if possible) at the top for air to exit.

•      The intake vent should be unobstructed, allowing airflow to the enclosure once the fan heater is in place.

b.  Set Up an External Fan Heater

•      Use a small, low-wattage fan heater designed for use in small spaces or enclosures. The heater should have a low temperature setting to prevent overheating.

•      Position the heater near the bottom intake vent so that the warm air is blown into the unit. Ensure that the fan heater's airflow is directed into the enclosure.

c.  Prepare a Thermal or Insulating Blanket

•      Use a thermal blanket (such as an emergency mylar blanket or insulation blanket), which will help trap the heat inside the enclosure.

•      Ensure the blanket is large enough to cover the enclosure without blocking the intake or exhaust vents.

2.  Heating Process

a.  Turn On the Fan Heater

•      Turn on the fan heater to its lowest setting to start warming the air inside the enclosure.

•      Allow the fan heater to blow warm air into the bottom intake vent. The warm air will start to raise the internal temperature of the enclosure and will encourage the condensation to evaporate.

b. Cover the Enclosure with the Blanket

•      Drape the thermal or insulating blanket over the enclosure. This should be done carefully, ensuring it covers the sides and top of the enclosure, trapping the warm air inside.

•      Ensure the intake vent is not blocked by the blanket, allowing the fan heater to continue blowing warm air inside.

•     Do not fully seal the vents—allowing some airflow is crucial for moisture control.
c. Monitor the Temperature and Humidity

•      Check the internal temperature and humidity regularly. The goal is to raise the temperature gradually inside the enclosure, allowing moisture to evaporate.

•      You can use a thermometer inside the enclosure to monitor the temperature.

•      If you have a humidity sensor, it will help you monitor the moisture levels inside the display casing.

3. Ventilation During Heating

a.  Allow Airflow to Evaporate Moisture

•      The warm air from the fan heater should circulate inside the enclosure, helping to evaporate the moisture and dry out the glass and internal components.

•      Allow the warm air to rise and exit through any exhaust vent (if available). This will help ensure the internal air is constantly refreshed and moisture is not trapped inside.

b. Periodically Adjust the Blanket (If Needed)

•      If you notice that the blanket is too thick or doesn't allow enough airflow, you can adjust it slightly or remove it temporarily. The idea is to keep the temperature increase gradual.

•      If you're using a blanket with reflective properties (like mylar), make sure it is positioned correctly to reflect heat inside but not block too much airflow.

4. Completion of Drying Process

a.  Check for Residual Condensation

•      After running the heating process for a reasonable amount of time (typically 30-60 minutes, depending on the severity of the condensation), inspect the inside of the glass for any remaining moisture or condensation.

•      If condensation is still present, continue the heating process for a bit longer until the moisture has evaporated completely.

b.  Turn Off the Heater and Uncover the Enclosure

•      Once the condensation has cleared and the internal humidity has been reduced, turn off the fan heater and allow the enclosure to cool down.

•      Remove the blanket carefully to avoid trapping heat inside.

c. Power On the LCD Display

•      After the condensation has been removed and the temperature has stabilized inside, power on the LCD display.

•      Observe the display for any issues and ensure no further moisture buildup occurs.
