Before you buy
- When both units run at the same time, they share the available capacity and the fans work at the lowest speed.
- The refrigerant circuit is not hermetically sealed, and no refrigerant may be added beyond the pre-charge. Laying the pipes and commissioning are work for a qualified installer.
- The Master needs two openings through the exterior wall. For heating, a condensate drain is mandatory.
