3 Piping work and
refrigerant charge
If the drain hose connection side is to be changed: remove the drain
hose plug and fit it in the pipe on the opposite side.
Prepare a polyvinyl chloride (PVC) pipe with an outer diameter of
26 mm.
Connect the drain hose as indicated in the figure.
The drain hose must have a gradient of 1% (1/100) to 4% (1/25).
The drain hose cannot be installed on an upwards line, not even
on one section of the installation. In this case, the condensate water
accumulates at the lowest point immediately before the raised
section of the installation.
Use vinyl chloride adhesive to connect the drain hose.
After inserting the pipe fully, secure it using the clamp supplied.
Check the correct working order of the drainage system.
