INSTALLATION (cont.)
Condenser Duct Installation (Optional)
Condenser intake and exhaust ducts can be installed to exchange outdoor air.
CAUTION:
1. Louver must be installed to avoid infiltration of strong wind or rain
from outdoor.
2. Condenser intake and exhaust ducts must be installed at level lower
than the unit to avoid water flowing into the unit (cause of water
leakage or unit problem).
1. Use a 12 inch diameter insulated duct with low friction and air resistance.
The duct should be bent in a large radius. If the bending radius is less than
15.0 inch (381 mm), use vanes or guides to reduce air resistance.
2. Make sure the ducts are secured in order to absorb vibration from the unit.
Avoid sharp bending on the duct and have air ducts travel in a straight line for
improved performance.
Field supplied hardware requires:
• Insulated 12 inch diameter flexible ducts
• Louver for condenser intake and exhaust
Refer to the condenser external static pressure of “Technical Specifications”
on page 58.
