down 20mm or more.
2. Install horizontal drainpipe with a slope of 1/100 or more and fix it by hanger space of 1~1.5m.
3. Install the air vent in the horizontal drainpipe to prevent water flow back to the indoor unit.
• You may not need to install it if there were proper slope in the horizontal drainpipe.
