Conair Portable Chillers Series 1Water-Cooled (W1) and Air-Cooled Models (A1) withTIC Control

The Troubleshooting section covers problems directly related to the operation and maintenance of the portable chiller. This section does not provide solutions to problems that originate with other equipment. Additional troubleshooting help can be found in manual supplied with the other equipment.

Conditions you may see are:

●electrical - a fuse is out, a switch has tripped

●mechanical - pump, condenser not working

●physical - water flow incorrect

As part of troubleshooting you need to know the status of the inputs and outputs. Open the electrical enclosure and check the status of the inputs and outputs. When they are in normal range, the numbers are highlighted. If the number is not high- lighted, it is out of range.
