Unit Description
The RTHC units are single compressor, helical-rotary
type, water-cooled liquid chillers designed for
installation indoors. Each unit is a completely
assembled, hermetic package that is factory-piped,
wired, leak-tested, dehydrated, charged (optional),
and tested for proper control operation before
shipment.
Figure 2 and Figure 3 show a typical RTHC unit and
its components. Water inlet and outlet openings are
covered before shipment. The oil tank is factory
charged with the proper amount of refrigeration oil.
The unit can be factory charged with refrigerant.
Model Number Coding System
The model numbers for the unit, the compressor, and
the starter/control panel are composed of numbers
and letters that represent features of the equipment.
Shown in the three tables following are samples of
typical unit, compressor, and panel model numbers,
followed by the coding system for each.
Each position, or group of positions, in the model
number is used to represent a feature. For example,
in the first table, position 08 of the unit model
number, Unit Voltage, contains the letter “F”. An F in
this position means that the unit voltage is 460/60/3.
