1. Open break-outs on the right sidewall
2. Trim the 4 hoses (accessories) to length if
required. Likewise the condensate hose, which
hangs loose from the condensate pan.
3. Attach the hoses and the condensation hose and

The condensate precipitated from the air must be
removed frost-free via a condensate pipe with minimum
40 mm diameter. If surfaces are water permeable, it

vertically in the ground to a depth of at least 90 cm. If
the condensate is discharged into the sewer system,
ensure frost-free laying with a gradient.
Discharge of the condensate into the sewers is
permitted only via a funnel waste trap, which must be
accessible at all times.
Observe local regulations!
