Match the kit to your window
Identify the opening type and measure the frame. Check the supplied connector diameter and dimensions. A sliding-window kit will not necessarily fit a tilt-and-turn window. In a rented home, check what fixings are permitted before making permanent changes.
Follow the intended hose route
Use the specified hose and connectors without improvised extensions or crushed bends. Follow the manual’s length limits and clearance requirements. Hot exhaust belongs outdoors, not in another room, a corridor or an unsuitable shaft.
Limit warm air returning
Close the gap around the hose with a compatible window kit without blocking ventilation the home needs. A poor fit lets hot air back in. Do not attempt to make the home airtight; where combustion appliances are present, have exhaust compatibility checked professionally.
Allow for water and power
Read the instructions for condensate, drainage and storage. Use a suitable electrical outlet and follow the manufacturer’s electrical guidance. Before each season, inspect the filter and hose.
