16. Troubleshooting Guide

16.1 Refrigeration Cycle System

In order to diagnose malfunctions, make sure that
there are no electrical problems before inspecting the
refrigeration cycle.
Such problems include insufficient insulation, problem
with the power source, malfunction of a compressor
and a fan.
The normal outlet air temperature and pressure of the
refrigeration cycle depends on various conditions, the
standard values for them are shown in the table on the
right.
