3) Mechanical:
a)
The compressor mounted for operation on isolators. No special shipping fasteners are installed or
required.
b)
The condenser is designed for easy cleaning from the front by a spiral wire cleaning tool. This tool is
so designed to be driven either by hand or by a suitable electrical hand drill.

Refrigeration Cycle
3.4.1
The refrigerant cycle can be traced from any point in the system. Therefore, we will start with the liquid refrig
erant entering the evaporator. Entrance of the liquid to the evaporator is controlled by an automatic throttling
device called the expansion valve, which is controlled by temperature and pressure in the suction line. This
valve is designed to meter the refrigerant flow in such a way that refrigerant vapor leaving the coil is
superheated 10° F.
