Close the To Process and From Process valves.
Open the Fill/Drain valve and fill chiller
to the fill mark on the Water Level gauge. If the chiller is
overfilled, the excess fluid spills out the vent tube. DO
NOT OVERFILL.
Close the Fill/Drain valve.
Check the coolant level.
Once the chiller is turned on, the coolant level may drop
as the coolant begins to circulate, filling the connected
plumbing. Check the coolant level on the back of the
chiller. The coolant level shows on the water level gauge.
Make sure coolant level is filled to the mark on the gauge.
Set the Chiller control for ‘Percent Glycol’.
Set the percent glycol using the PLC control (see Setting
Percent Glycol, in the Operation section). Do this step
after main power is connected to the chiller and initial
startup has already been performed.
