Maintenance space (In case of 450 to 710 type)

Less maintenance space required than previous model
achieved by equipment size and weight reduction.

We have been using GHP. We considered to replace the existing GHP with GHP again since it was not necessary to up grade the electricity capacity.
We considered higher energy saving of combined connection type of outdoor unit and selected Aisin GHP again.

E1 series requires less maintenance space clearance for its compact design and light weight.
