YDAS MODELS:
YDAS models are constructed in two sections. One
section contains number 1 and 2 refrigerant systems
and their associated evaporator. This section is called
the Master section. The second section contains num-

evaporator. This is called the

Both sec-tions have their own control panel, but only
the master panel is fitted with a keypad and display.
