it's prohibited to place other devices.
*1. Dimension of maintenance door.
*2. Suspension point dimension
*3. The below-mentioned dimensions for maintenance door are
recommended to use if customers choose to remove the fi lter unit for
maintenance,
when the inside height of ceiling is over 600mm, dimension for
maintenance door should be:450mm*450mm
when the inside height of ceiling is less than 600mm, dimension for

1. Duct size (Nominal Diameter): Ø150/Ø200 (OA: Ø200; other: Ø150).
2. The above dimensions do not include the thickness of the insulation
material in the unit
■
Be careful of dew and frost
1. The two outside ducts must be insulated to prevent condensation.
(Material: Class wool. Thickness: 25 mm)
2. Outside air may come into the room in cold area and place where
outside air speed is high.
3. In order to prevent the water ingress , install the two outside ducts
inclined to outside
4. As shown in the fi gure, suppose a high temperature absorbing air
condition A and a low temperature absorbing air condition B are
plotted on the air line fi gure, then a high temperature air A is heat-
exchanged by the unit and goes out of the saturation curve as shown
by point C .In this case, the unit will be dewed or frosted. To avoid
this, you are required to heat a low temperature air B up to B' so as to
get C' below the saturation curve ,before using the unit.
