Short Duct Specification

Applicable for M5CKWS-AR Series Only

• The indoor unit is provided with air discharge and air intake “knock-out” hole for duct connection. However

the connection of the short duct for air discharge is possible on only one side.

• The use of short duct for air discharge will improve air flow distribution if there is an obstruction (such as

alighting fixture) or in a long, narrow room or an L-shaped room. It is also used for air-conditioning of two

rooms simultaneously.

Note: 1. Avoid to use the short duct on which the air discharge grille can be completely closed,

to prevent evaporator freezing.

2. In order to prevent condensation forming, be sure that there is sufficient thermal

insulation and no leakage of cool air when installing the short duct.

3. Keep the introduction of fresh air intake within 20% of total air flow. Also provide a

chamber and use a booster fan.
