Fluid Top Off
Remove the reservoir cap by unscrewing it counterclockwise.
To prevent the introduction of particulates into the system, fill the chiller
with the reservoir bag filter in place.
The reservoir has a sight tube and ball for easy fluid level monitoring. Slowly
fill the reservoir with clean process fluid through the funnel only, failure to
comply may result in internal spillage.
Note Filling the reservoir above MAX LeVeL fill line will result in an over
flow error ( O FLO ) causing the chiller to shut down. Also, fluids expand
when heated.

Note
Adding fluid that has a temperature differential with the fluid already in
the reservoir will temporarily affect the chiller's stability performance.

Before replacing the reservoir cap ensure the reservoir sight tube ball
stopper is securely in place.
