WARNING: Never operate the chiller with it's panels removed.
Always use the power switch to turn off the chiller when it is not being used.
Always ensure that all air inlets and outlets are free from obstruction.
Be sure that the reservoir is filled with fluid prior to powering up the unit (see Fluid Recommendations
page).

Process Water Flow, Units and Pump and Tank (Standard)

Follow standard plumbing practices and local codes in making water connections. The chiller inlet and outlet
connections are 1/2". Flexible hose and fittings are recommended for plumbing the system. A No. 20 mesh strainer
should be installed on the chiller inlet to prevent foreign particles from entering the system and should be cleaned
monthly. Lines should be routed with as few bends as possible. Prevent lines from running near radiators, hot water
pipes, etc. Any lengths of tubing that are exposed to high ambient temperatures should be insulated to prevent
condensation and/or significant liquid heat loss.
After ensuring that the system is free from the obstruction, that all valves are open and the reservoir when
available is full, push the CONTROL POWER switch to the "ON" position. The pump should now be operating.
