Check Heating Fluid Level

Gradual fluid evaporation can occur, therefore, check the level of heating fluid monthly.

1.Remove plug (6).

2.Place flexible object in port so that it protrudes down. Pull out to observe level.

3.Refill heating fluid as necessary. See Fill Heating Fluid, page 15, for instructions.

Check for Heating Fluid Leakage

When spray material is drained and heating fluid is full, inspect the inside of the hopper for any signs of heating fluid leakage.

Drain Heating Fluid

1.Turn off all heaters and allow heating fluid to cool for a minimum of 8 hours.

2.Place either a 1-gallon (4-liter) or 3-gallon (7-liter) pail directly beneath drain plug (37).

NOTE: Only 1-gallon (4-liter) pails fit beneath drain plug if hoppers are mounted on the back of the frame.
