1. Feature
1.1 Compact size
1.1.1 Only 210 mm (22~56 models) or 270mm (71 to 140 model) in height, this model can be installed in
rooms with as little as 240 mm~300 mm depth between the drop-ceiling and ceiling slab.
1.1.2 The EXV is built-in design of the indoor unit, makes the main body without an extra throttle kit box.
1.2 Wide capacity range
—The capacity ranges from 2.2 kW to 14.0 kW, totally ten models.
1.3 Two external static pressure settings for added flexibility
just exchange the wiring connection of ‘SH’ and ‘Hi’. P2 and P3 as
the right side diagram.
1.4 Convenient installation
1.4.1 The EXV is fixed inside of the indoor unit
1.4.2 Standard filter with aluminum frame, which is removable
downward from bottom.
1.4.3.Suction chamber is included as standard equipment
1.4.4 Flange for air in/outlet duct connection is standard.
1.4.5 Air inlet from back standard and from bottom optional.
Size of the plate from bottom and flange from back is same, which
makes it is possible to easily convert the air return from back to
bottom by installer.

1.4.6 Standard built-in drain pump
Drain pump is equipped as standard accessory with 750 mm pumphead.
1.5 Flexible control and convenient for maintenance
1.5.1 The display board is connected with the E-box in factory, which makes trouble-shooting easier by
LED display.
22~56 model
71~140 model
1.5.2 The Electrical control box is possible to remove 1m far away from the main unit, which is suitable for
the small space hard to maintain.
1.5.3 The EXV is fixed inside of the indoor unit, which is screw connected, can unscrew from the liquid
pipe which is very convenient for maintenance.
1.5.4 Standard functional port such as Remote On/Off Dry contact switch, and Alarm signal output (220V)

4. Service Space
Ensure the needed spaces for installation and maintenance.
The ceiling is horizontal, and its structure can endure the weight of the indoor unit.
The outlet and the inlet are not impeded, and the influence of external air is the least.
The air flow can reach throughout the room.
The connecting pipe and drainpipe could be extracted out easily.
There is no direct radiation from heaters.
Below is the recommended duct installation method:
Keep min. 600*600 space for checking &maintenance:
