1. Features
Design flexibility.
Compact design and flanges of air flow inlet and outlet as standard. It is suitable for installation
in rooftop and ground.
Durable construction.
Pre-painted exterior cabinet panels pass 1000 hours salt spray test for durability.
Weather-resistant construction with capped steams and sloped top panels design.
The rooftop package air conditioners with special anti-corrosion treatment are suitable for
seaside areas or the areas exposed to acidic substances. (It should be customized.)
Reliable scroll compressor.
Famous brand compressor, it is more reliable. No complex internal suction and discharge
valves for quieter operation and higher reliability. Compact and light-weight design, fewer
moving parts design.
Adjustable pulley
Through changing the working pitch diameter of the pulley mounted on driver shaft, in turn the
revolutions per minute of the driven shaft will increase or decrease to change air volume.
Multi-protection design.
Multi-measurement can ensure units operate normally and reliably:
System current protection;
High/low-pressure switch protection;
Temperature sensor on/off protection, etc.
The three-phase protector can be customized.

Easy to installation.
Removable access door on the electric box is standard. It is easy to move the cover of the
electric box. Only connect the wires of power supply, and no need to connect any signal wires.
Reserved external drainage port, quickly and accurately connect the rubber drainage pipe.
The unit provides external pressure gauge ports for convenient and fast checking system
pressure without removing the panel.
System self-diagnostic function.
Press the Check button in Main PCB board, and the LED display of PCB board in unit will
display the normal checking code. If the unit is in running with abnormal operation, the LED
display will show the error code.
EHK (Electrical heater kits) and air intake filter as optional.
Wired controller as standard. Besides Midea controller, other brand thermostat can be matched
as optional solution.
Centralized control function can be achieved through the centralized controller as optional.
MD-NIM01 should be connected between the rooftop package units and centralized controller.

Notes:
1. Nominal ton only for reference. Cooling capacity as per specifications;
2. Cooling capacity test condition:
Outdoor ambient temperature: 35°C , indoor temperature: 26.7°CDB, 19.4°CWB;
Heating capacity test condition:
Outdoor ambient temperature: 7°C DB, 6°C WB, indoor temperature: 20°C ;
3. Units are suitable for operation to ±20% of nominal indoor air flow.
4. ESP: external static pressure;
5. Sound pressure level values are measured in a semi-anechoic room, at a position 1 meter in front of the unit
and (1 meter + Height of the unit) / 2 above the floor;
6. Specifications are subject to change without prior notice for product improvement.
