Introduction
Laird Technologies’ solid-state recirculating liquid chillers are designed to provide cooling for a wide
range of water solutions, and can be used for cooling in many medical, laser, and test laboratory
applications. They are intended to work in “closed loop” systems that separate the coolant from the
outside environment, protecting the purity of the cooled product.
This manual provides the necessary general information for proper installation and operation and has
been developed to achieve the best results when using the Laird Technologies chiller.
Incoming Inspection
Laird Technologies’ chiller units are designed, built, and packaged to withstand the shock and vibration
normally associated with shipment by common carriers. Occasionally, improper handling during
shipment, such as excessive vibration, crushing, etc., will cause damage to the product. Therefore, a
thorough inspection should be provided upon receipt of all shipments. Any packaging tears, dents,
scratches, or loose objects are signs of damage and should be noted on the Freight Bill. Packages
should be opened promptly and units inspected for concealed damage.
If damage is found, an
immediate claim must be filed with the freight carrier and an inspection requested.
Retain all
packing materials. Laird Technologies cannot be responsible for Consignee’s failure to file a timely
freight claim.
