No special tools are required. Each approach offers advantages and disadvantages.A self-contained unit is simpler to install and maintain, since it does not have any external refrigerant lines. It is also less expensive than a split system of the same BTU capacity. On the other There are two basic types of auxiliary air syst

SPECIFYING THE SYSTEM About Insulation. For a day cab with limited engine-off times (less than 2 hours), we recommend replacing the existing bank of batter- ies with an equal number of AGM 31 batteries. Before we go any further, let’s talk briefly about insulation. Most truck sleepers today are insulated with a value of approximately R 1 to R 1.25. Compare this to the insulation of R 30 that is required in most new housing con- For a typical sleeper, you will replace the existing bank of four ba
