Yes. You can use the included drainage hose or a self-purchased hose to connect to the drainage outlet at the back of the unit, directing the water straight to an indoor drain. To ensure proper drainage, the hose outlet must be positioned lower than the unit's drainage hole (utilizing gravity flow). We recommend directing the hose to a shower floor drain, or similar low-level drainage point. Please do not direct the hose to a washbasin, kitchen sink, or any location higher than the product's drainage outlet; doing so will prevent water from discharging properly and may lead to an automatic shutdown or water leakage.
