1.2 Main characteristics
1.2.1 Expansion valve
1). Extremely low noise, 3dB(A) lower compared with which put EXV into the indoor unit case.
2). Easy maintenance. Being separated from indoor unit or been fixed on the body, thus it can be replaced easily.
3). Easy installation, just quick connection by flare nut.
Model DZJLBJ03-A DZJLBJ04-A
Remark:
(1) One electronic expansion valve can be applied to one indoor unit.
(2) Except indoor units MDV-D112T2(/N2), MDV-D140T2(/N2), MDV-D112T2(/N2)-B and
MDV-D140T2(/N2)-B adopt DZJLBJ04-A, other models all adopt DZJLBJ03-A.
(3) Electric Throttle Kit needn t order separately, it has been packed with the indoor units together in the
factory.

---Owing to the multiple-blade fan rotor and the air guide design, the airflow is getting smoother and more
comfortable
3) One direction air flow
---Quick cooling
4) Stylish design
---Be harmonious with any interior decoration and creates an elegant environment
5) Ultra thin machine body
---Space saving: only 235mm (28,36 models)
---Space saving: only 198mm (45,56,71 models)
/198mm /198mm
6) Convenient installation
---Able to be flexibly installed in various corners
---Standardized sectional module
--- More flexible in routing the tube through the ceiling space due to the condensed water can be lift through
the drain pump up to 340mm above the drain port
7) Easier to do cleaning and maintenance
---Flat type suction grille of easy cleaning

3.1 Feature
1) Low operation noise
---Streamline plate ensures quietness
---Creates natural and comfortable environment
2) Efficient cooling
---Equal, fast and wide range cooling
Four-way airflow
3) The adoption of the most advanced 3- Dimensional Screw fan
---Reduces the air resistance passing through
---Smoothes the air flow
---Makes air speed distribution to the heat exchange uniform
3- Dimensional Screw fan
4) Improvement for easy installation and maintenance
---Little space is required for installation into a shallow ceiling
---Because of the compactness and weight reduction of the main unit and panel, all models can be installed
without a hoist

5.1 Features
1) Economic and convenient installation
---Several diffusers branch off from an indoor unit, adjusting the room temperature, which makes many rooms
to be air conditioned with only one indoor unit.
---All models feature thin design making them applicable to ceiling pocket that tends to be shallow
2) A wild variety of optional accessories
---Including front clapboard, panel, canvas air passage, filter, etc.
Canvas air passage Clapboard
Panel
3) A long-life and high-efficiency filter
Filter
4) Way of air intake and inserting air filter
---Air intake can be positioned either at the back or below the unit. Similarly, the air filter also can be inserted either from the back or
from the bottom of the unit.

MDV-D Indoor Units
8.1 Features
1) Convenient installation
---The ceiling type can be easily installed into a corner of the ceiling even if the ceiling is very narrow
---The is especially useful when installation of an air conditioner in the center of the ceiling is impossible due
to a structure such as a lighting
Floor & ceiling type
2) Double auto swing and wide angle air flow
---Air flow directional control minimizes the air resistance and produces wilder air flow to vertical direction
---The range of horizontal air discharge is widened which secures wider air flow distribution to provide more comfortable air
circulation no matter where the unit is set up
3) Water proof by utilizing the absorbing plastic film on water collector
4) Low noise level plus compact size
---Shape of the blades has been improved to prevent noise caused by turbulence

9.1 Feature
(1)The evaporator employs a Multi-bend structure which enlarges the heat exchange surface.
(2)The front panel is tightly fixed with the front frame by simply buckling the latter with a buckle mechanism on
the panel.
(3)The manual force switch employs comfortable switch push buttons.
