DSA 3018/3218 Operations for Freon Applications
When using DSA 3018/3218 modules in Freon Applications special considerations must be taken. In order
to prevent premature deformation of the seals within the DSA 3018/3218's valve, it is important to leave the
module in the following ‘dormant’ state.
• Apply CTL2 and PRGCTL pressures
• Ensure no Px pressures are applied
• Freon present must be vaporized
Any time the module will be left inactive for a significant period of time it should be left in this state.
Adhering to this procedure will help ensure long life and prevent any premature maintenance requirements.
