Setting Operational Parameters
The Chiller’s various operational parameters, such as temperature, flow rate, and pressure alarm values, are all
user-adjustable. They are accessed by pressing and holding the Units/Menu Button until HL appears on the
pressure/flow rate display. Pressing and releasing the Units/Menu Button once HL appears allows you to scroll
through the various parameters; rotating the Select/Set knob allows you to change the displayed setting. You can
accept the displayed value by either pressing the Select/Set knob or allowing the display to timeout.
