7-9 kW models
Ceiling
When connecting multiple drain pipes, install the pipes as illustrated below. If the condensate pump
drain outlet is not used and one of the gravity drain outlets is used, fit the plug (from the gravity
outlet) into the pump outlet and unplug the pump from the indoor PCB terminal CN13.
Pass the drain hose through the wall. Make sure the water drains to a safe location where it will not
cause water damage or a slipping hazard.
