Operating Limits
The units are designed for indoor, non-freezing locations. Outdoor locations will require special design considerations.
Note:
Min. ECWT(° C) = 2,92+(ELWT)-0.75*DT
Where:
ECWT = Entering condenser water temperature
ELWT = Leaving chilled water temperature
DT
= Chilled Water Delta-T at full load
FL
PLD = The percent chiller load point to be checked
For example, at 7° C ELWT, 5° C
Label Identification
1 – Manufacturer's logo
2 – Refrigerant type
3 – Non flammable gas symbol
4 – Emergency stop
5 – Hazardous Voltage warning
