Installation Tip:
SAFE-HEET engine heaters are installed with a two-part adhesive. The engine heater can be installed quickly and easily by using the 707 temperature controller at half power. At temperatures below 70 degrees F the temperature controller must be used to ensure proper adhesive cure. Proper adhesive cure is essential to service life of the heater.
