Under-Window Fit Check

The cabinet is 600 mm high and 250 mm deep on every model — only the width changes. This checks a chosen model against your sill, your wall run and the clearances the unit needs to be serviceable later.

Model

Sill height above finished floor (mm)

The discharge must sit below the sill for the air to run up the glass.

Window width (mm)

Cabinet width should not exceed the window width, or the air curtain misses part of the glass.

Clear wall run available under the window (mm)

Clear space at the service side (mm)

Water and controls side. This is what a technician needs in year six.

Clear space in front of the discharge (mm)

Furniture and curtains must not block the supply face.

Results appear here. Clearances are the KOVEN AIR window-side installation values for the KA-FP-WM series.

Fixed dimensions across all nine models: height 600 mm, depth 250 mm, side discharge 130 × 130 mm, top discharge offset 150 mm, DN20 supply / return / condensate. Clearances: 50–100 mm under the base for levelling feet, 20–50 mm at the back for pipework and return air (do not push it tight to the wall), ≥300 mm at the service side, 150–200 mm clear in front of the discharge, condensate fall ≥1% to the drain. Fix to the floor and brace to the wall; support the pipework independently of the cabinet.
