NOTE:
Connect the connecting pipe to the indoor unit first and then connect it to the outdoor unit. Pay attention to the
bending and Iayout when preparing the connecting pipe in order not to harm it. Do not screw the joint nut too
tightly, otherwise leakage will be caused.
Check the connection for leakage. Use water-soap solution
Insulate gas pipes and their
connection to prevent condensation
and water leaks by covering provided
insulation sheet completely around the
connection and nut
Fasten the isolation sheet against
tear-off

Install drain pipe/hose
During cooling condensate occurs and must be drained
The diameter of the drain hose must be at least of the same size as the drain pipe from the cassette
The slope of the drain pipe/hose must be min 1% (1cm/1m) and go ALWAYS down. No intermediate

The drain hose shall be at short as possible
Install a siphon at the end of the hose to avoid bad smell
Provide an uprising hose straight at the beginning of the hose to prevent backflow of the condensate into
the unit
