Preparing Glycol
MIXING GLYCOL SOLUTION
1. Inspect the glycol reservoir tank for dirt and/or
foreign debris. The tank must be clean before
mixing glycol solution.
2. Locate the glycol kit:
Model 75
3 Gallons (19 ltr) Glycol
Model 150
5 Gallons (19 ltr) Glycol
Model 300
15 Gallons (57 ltr) Glycol
Model 450
20 Gallons (75 ltr) Glycol
3. Pour the glycol into the reservoir tank.
4. Add water until level of glycol/water solution
reaches the “Fill Here” mark located on tank wall.
NOTE: The glycol/water solution in the water bath is
now mixed to the proper ratio.
5. Push the switches marked “Compressor” and
“Agitator” if equipped to the ON position. After
compressor cycles OFF, check to ensure glycol
solution reads 27°F (-2.7°C) to 29°F (-1.6°C).
!
Caution
Do not turn on the circulating pump(s) until
system installation is complete.
!
Caution
Glycol water ratio should be maintained at a 3 to
1 ratio (17-22 Refractometer). Additional water
will be required after starting pumps and solution
fills circulation system.
