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.

The thermostat has a range that is pre-set at the factory. The range is 40° F (5° C) to 100° F (38° C). If operation 
outside of this range is required, please contact the Cornelius Technical Service Department.

WARNING: 

Never

 operate the chiller with it’s panels removed.
