EVP Chiller Applications
Start the chilled water circulating pump by closing the field provided pump disconnect switch and
turn the pump control circuit switch 5S1 “On”.
Check the flow device to ensure it opens and close properly.
With water circulating through the system, check the EVP chiller pressure drop and adjust the flow
(if necessary). Refer to the appropriate EVP chiller size in Figure 44 for the operating pressure drop.
Freezestat Setting
At the remote panel, set the freezestat at a minimum of 5oF above the chilled water freezing
temperature.
