Flange/Victaulic Adapter Kit For Dynaciat; Glycol/Water-Mix Antifreeze Protection - CIAT DYNACIAT power LG Manuel D'instructions

If the hydraulic circuit is drained for a period of more than
one month, fill the entire circuit with nitrogen to prevent
any risk of corrosion.

13.2 FLANGE/VICTAULIC adapter kit for DYNACIAT

The connections to the exchangers are the VICTAULIC type.
A FLANGE/VICTAULIC adapter kit can be supplied separately to be fitted on site by the installer to allow flange connection to
the hydraulic system.
Two kits are available:

14 GLYCOL/WATER-MIX ANTIFREEZE PROTECTION

The table and the curves below indicate the minimum percentages of glycol with which the system must be provided depending
on the freezing point.
WARNING: The glycol concentration must protect the fluid at least 6°C below the water outlet temperature specified for the
evaporator to allow correct setting of the minimum pressure controller at the evaporator.
Glycol concentration required
Volume concentration in %
Ethylene glycol
Minimum water outlet °C
Propylene glycol
Minimum water outlet °C
Important: The values are given for guidance only, according to the standard characteristics of the MEG. These may vary
depending on the MEG manufacturer, therefore it is important to refer to the manufacturer's data to ensure protection is provided
to the required temperature.
For a glycol concentration greater than 40%, a special pump must be used
