IMPORTANT

Be sure to have read and understood these 

instructions before beginning the installation 

process.

PRE-INSTALLATION CHECK LIST

Make sure that the unit can physically fit in to 

the desired location.
The energiSava 250 unit should be 

situated so that access for maintenance or 

replacement of parts is possible. Make the

the most direct route and using as few 

bends as possible will reduce air resistance 

and improve the efficiency of the unit.
