INTRODUCTION The REMCOR “CH”Series Liquid Chillers (Models CH550--A and CH551--A) are specifically designed to cool clean liquid before it is circulated to the cooling application. The Unit includes a complete refrigeration system and associated controls housed in a sturdy sheet metal enclosure with perforated panels for air circulation.
INSTALLATION INSTRUCTIONS LOCATION Locate the chiller indoors in a well ventilated area with ambient temperatures in the range of 65°to 100°F. Allow a minimum of six inches of clearance around the chiller for proper air circulation. Avoid hot air discharge from other equipment or enclosed areas where heat could build up and cause a rise in ambient temperature. PLUMBING Follow standard plumbing practices and local codes in making liquid connections.
When the flow rate to the process is critical, a flow meter and valve should be installed in the line in order to obtain the proper flow rate. On Units with optional bypass valve, the aforementioned valve can be omitted and the flow can be adjusted with this valve. Turning the valve clockwise increases the flow to the process whereas turning the valve counterclockwise decrease the flow to the process. Once these start--up procedures are complete, the chiller is ready for standard operation.
