Note:
① .
The design of this unit conforms to the requirements of EN14511 standard.
② .
The air volume is measured at the relevant standard external static pressure.
③ .
Cooling (heating) capacity stated above is measured under nominal working conditions
corresponding to standard external static pressure. The parameters are subject to change
with the improvement of products, in which case the values on nameplate shall prevail.
④ .
In this table, there are two outside DB values under the low temp cooling conditions, and the
one in the brackets is for the unit which can operate at extreme low temperature.
