1.3 OPERATING LIMITS
WARNING!
The Manufacturer tests the hydraulic parts with dried compressed air. This ensures that no water is pres-
ent in the water circuits, thereby preventing the possibility of freezing during storage prior to installa-
tion.
However, during storage, positioning and installation procedures, it is essential to take extra care not to
ll the water circuits, even accidentally, before all the necessary antifreeze measures stipulated in the
design specications and in this manual have been implemented (e.g. Insulation, added glycols, etc.).
WARNING!
The ambient thermal load must not be less than 40% of the unit’s rated cooling capacity in the case of
direct expansion units.
A lower thermal load will lead to imprecise temperature and humidity control and frequent powering
on/o of the compressor.
WARNING!
In very cold climates (from -10 ° C), in the case of inverter compressors and in the case of oversized con-
densers, the use of the LAC (Low Ambient Control) valve is recommended in order to avoid the risk of low
condensation temperatures.
