Pipe Length Elevation and Additional Quantity of Gas
• The outdoor unit is charged with the
refrigerant for standard pipe length.
• When the connecting pipe length is longer
than standard length, additional refrigerant
should be added into the unit according
the above table through the service port on
3-way service valve on the outdoor unit.
• Please maintain the shortest distance (3 to 5
meters) and shortest misalignment possible
between the indoor and outdoor units.
• The maximum allowance length and height
is based on reliability.
• Exceeding the maximum may cause poor
performance or malfunction.
• When the outdoor unit is installed above
the indoor unit, oil trap should be installed
every 5-7 meters.
