Unit Description
Introduction
Thermo King V-520 refrigeration systems are designed for medium-sized
trucks and vans transporting fresh, frozen, and deep frozen goods.
The condenser for a RT (roof top) unit is located on the roof top of the
vehicle. The condenser on a NM (nose mount) unit is located on the front
nose of the cargo box. The evaporator is mounted on the cargo
compartment ceiling. SPECTRUM
®
units have an evaporator in each
temperature controlled compartment.
A belt driven compressor running off the vehicle’s engine operates the
refrigeration system during mobile operation. SmartPower
™
models have a
second compressor located inside the condenser. This compressor is belt
driven off an electric motor when connected to an AC power source during
stationary operation.
The user friendly Direct Smart Reefer (DSR) controller makes operating your
unit simple, while its design allows for ease of service.
The operating mode is selected automatically: When the unit is connected to
an electric power source, engine-driven operation is automatically blocked. If
the vehicle engine is started up while the power cable is still connected to
the electric power source, the unit will continue to operate in electric standby
mode. It is not possible to start the engine-driven compressor until the
power cable is disconnected from the unit.
