Duct connection
Testing the drainage
Drainpipe
Drain water drops
Prepare a little water about 5 liters.
Make sure to insulate the duct refering to the picture.
Wind the aluminum tape securely round the duct connection so that the air in the duct does not leak.
To prevent rain from permeating duct connection, install the two outdoor ducts (OA, EA) on a slope.
To prevent condensation from forming, insulate the three ducts. (Outdoor ducts and Indoor supply air duct)
(Material: Glass wool of 25 mm thick)
Outdoor air duct must be installed at least 3m above the product.
Install electric damper and back draft damper during duct installation.
1. Pour water into the base pan in the indoor unit as shown in figure.
2. Confirm that the water flows out through the drain hose.
3. Check drain water drops at the end of the drain pipe.
4. Check that no water leaks from joints in the drain installation.
5. Reassemble the cover of water supply intake.
• The use of flexible hose made of fiber glass is recommended to minimize noise. Install the duct at least over 3m
to reduce the noise as well.
• If the duct is not attached correctly and securely, it may result in malfunction.
• To prevent a short circuit, install the indoor air intake as far away as possible from an air outlet.
