Air Conditioning & Engine Coverage

The manual documents the AC25D’s Carrier 38AP condensing unit with its dual hermetic scroll compressors, microchannel condenser coils, and full safety circuit (short-cycle, low superheat, loss-of-charge, reverse rotation and high-pressure protection). It details the Murphy Power View (PV101) engine control module, the fuel and cooling system specifications, and the periodic maintenance intervals — daily, 125-hour, 250-hour, 750-hour and 3000-hour checks — needed to keep the unit running reliably in the field.

Illustrated Parts List

The TUG Model AC25D Air Conditioning Unit Operation, Maintenance & Parts Manual includes a fully illustrated parts breakdown across 17 figures — frame panels and doors, fifth wheel assembly, rear axle installation, blower assembly, distributor hose, compressor piping, condenser unit, engine assembly and installation, fuel system, air intake assembly, cooling assembly, exhaust system, generator installation, control box assembly, control panel assembly, fuse installation, and battery assembly — each cross-referenced to part numbers, vendor codes, descriptions, and effectivity.

Why Technicians Rely on This Manual
