A. Troubleshooting
The most common problems encountered with a PORT-A-COOL® unit are operational problems. The
PORT-A-COOL® unit consists of three systems. It is important to determine which system of the PORT-A-
COOL® unit the problem is associated with. Certain problems may be associated with more than one sys-
tem.
When determining which system that the problem is associated with you must first define the problem,
i.e., the pump is not running. Although this might seem a bit over-simplified, several things may cause a
particular problem. So while defining the problem, a careful check of all systems should be made to fully
understand the extent of the problem.
If you have a complete understanding of all the systems of the PORT-A-COOL® unit and how they depend
on each other, it becomes much simpler to define and solve any problems.
Although the PORT-A-COOL® unit is designed to be simple to maintain, it will be necessary to have some
basic hand tools (screwdrivers, pliers, adjustable wrenches, etc.) as well a volt/ohm meter for troubleshoot-
ing the electrical system.
FAn SYSTEM
This section is divided into the two categories of fans used on all PORT-A-COOL® models: Direct Drive
and Belt Drive. Both have some symptoms in common, and both have problems that are particular to each.
CAUTION
Please use caution when troubleshooting or repairing all electrical compo-
nents. Be certain that all power is disconnected from the PORT-A-COOL® unit
before the cooling pads are removed to gain access to the fan.
