Quick Tip: If your machine has vapor locked, turn off your heater and pump and unplug your machine. Allow the machine to cool down. To help alleviate built-up pressure in your heater more quickly, depress (push down) the spring-loaded nipple located inside of the female disconnect on the machine. Use caution.
To avoid vapor lock, the pump must be primed before the heater is turned on. Read the information below or click on the link to watch a video: https://youtu.be/dqr9Az2cTvk.
