NOTES:

1

Contact a Daikin Applied representative for performance at specific operating conditions, as some limits depend on unit 

 

configuration

2

Antifreeze temperature limits must have appropriate glycol concentration

3

Allowable leaving fluid temperatures depend on Saturation Temperature

4

5%-95% relative humidity, non-condensing

5

For non-conditioned equipment rooms please contact factory for maximum dew point, limits may depend on specific selection.
