3.Duct Work

(1)All series units are equipped with horizontal supply and return air openings. Duct connection to the unit should be made with duct flanges and secured directly to the air openings with flexible duct connectors to avoid normal noise transmission.

(2)For vertical air supply, a field supply plenum should be used.

The figure below shows the recommended method for duct connection.

(3)To prevent air leakage, all duct seams should be taped.

Ducts run in air spaces that are not air-conditioned must be insulated and provided with a vapor barrier. Ducts exposed to the outside must be weatherproofed. For quiet operation, we recommend that the insulation on the supply duct be placed inside, lining the duct.

(4)Where ducts from the outside enter a building, the duct openings in the building should be sealed with weather stripping to prevent rain, duct, sand,etc. from entering the building.

(5)Correctly sized filters must be fitted and there is no provision within the unit, however the filters may be installed in the return air.

(1) A 1 FPT condensate drain fitting is provided. The

drain pipe can be led out at the right or left side.

Under standard specifications, it is led out at the left

side and the right side is covered.

(2) The drain pipe must be provided with a trap on the

outside of the unit and also installed at an incline for

proper drainage, as shown below.

The drain pipe should extend below this level.

(3) To prevent condensate formation and leakage,

provide the drain pipe with insulation to safeguard

against sweating.

(4) Upon completion of the piping work, check that there

is no leakage and that the water drains off properly.
