The minimum flow increases linearly up to 6 gal/min (23 L/min) at 60
°C (140 °F.)
2. Wait for the coolant flow to stabilize.

2. Turn on the coolant supply.
Note:
Minimum flow rate is 4 gal/min (15 L/min) at 5 °C (40 °F).
The minimum flow increases linearly up to 6 gal/min (23 L/min) at 60
°C (140 °F).
