Notes
1. Evaporator ∆T = 5K.
2. The unit must be either equipped with frost protection options for the water
type heat exchangers (evaporator and heat recovery) and the hydraulic
module (if used), or the water loop must be protected against freezing by
the installer with an antifreeze solution
3. These ranges are guidelines only. Verify the operating range with the
electronic catalogue.
