RESERVOIR COOLANT LEVEL
The reservoir volume should be checked daily before using the cooler. Remove the reservoir fill cap and check the coolant level. The reservoir is full when the coolant level is just below the input elbow of the reser- voir (approximate. 2 Gal / 7.6 ltrs). Keep the reservoir full, especially after disconnecting the water lines or changing the accessory being cooled.
COOLANT TREATMENT
RECOMMENDATION
This procedure is intended to provide a means of reducing the objectionable amount of fungal and bac- terial contamination that has occurred in
Limitations:
