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.
