SYSTEM WATER CONTENT
MINIMUM SYSTEM WATER CONTENT
NOTICE: Under no circumstances does the unit have to be operated in a system in which the content of the water circulating is below the MINIMUM SYSTEM WATER
CONTENT, under penalty of the warranty expiration. Aermec cannot be held responsible for any malfunction of the units which are operated in a system in which the
content of the water circulating is below the MINIMUM SYSTEM WATER CONTENT and for their consequences
The minimum water content of the system allows you to limit the activations and shutdowns of the compressor.
To calculate it use the formula Pc (ton) X gal.

NOTICE:
in the case of several units connected in parallel, the designer must ensure that the configuration of the system and the management logic adopted do not
cause too frequent START/STOP cycles and / or sudden changes in the water flow rate of the groups in operation
MAXIMUM SYSTEM WATER CONTENT
Units with the hydronic kit mounted come standard with the expansion vessel set at 21.8 psi, the pressure relief valve and the water filter mounted.
The maximum system water content depends on the capacity of the expansion vessel and on the calibration of the pressure relief valve.
