1 General Features 1.1 Wide Range and Stepless Capacity Modulation • • Running ration of compressors % • Wide capacity modulation range (10%-100%) According to changing the ralio of “loading time” and “unloading time”. MDS can modulate the capacity steplessly. Lower the energy consumption and running cosl. MDS system Inverter system Total capacity of operating indoor units 1.2 Accurate Temperature Control and Quick Response • The cooling/heating capacity of the indoor units is controlled by the EXV.
1.4 Energy Saving The inverter system’s capacity modulation range is from 30% to 100%, while MDS system’s capacity modulation range is from 10% to 100%. Quick response to the capacity modulation. Min. power consumption is only 10% of the full load power consumption. Compared to the inverter system, there is no power consumption of transducer. Compared to the nominal capacity scroll system, it can save 20% energy consumption.
1.7 Space Saving • Compared to scale size central air conditioning, MDS system is high centralized, no need for special equipment room to save more space, and bring more benefits. Traditional central air conditioning MDS system 1.8 Easy to Install and Simple to Maintain Easy Installation • MDS system is simple and reliable, and outdoor unit can be connected with several indoor units, so it is easy for installation.

6.2 Installation of the Combined Outdoor Units (Suitable for Model of MDS260/280/300) Two outdoor units can be grouped as one outdoor unit, to couple with multi-indoor units. Grouped outdoor units installation is more complicated than that of the single outdoor unit; please read the below notes carefully before installation.
Balance Piping Connection • • • • Balance piping must be installed. Balance piping shall be connected through the hole of side panel or base panel or the piping connection position with the other outdoor unit. Balance piping shall be installed horizontally and orderly, and shall be lower than the access valve for balance piping. Protect the balance piping carefully and avoid touching any other parts, especially need to keep the piping from touching the wall of hole.
6.3 Indoor Unit Installation To Choose the Position of Installation Improper installation position will influence the cooling and heating performance, or even cause malfunction or accident. To follow up the below instructions: • Ensure air flow everywhere of room. • No barrier for air flow. • Enough maintaining space for installation. If not, it will cause difficulties to maintain the unit in future. If not, it may cause the unit falling off. • Wall or ceiling shall be strong enough to support indoor units.
Duct Working Installation Air Supply Duct Working Installation Two types of air supply duct working are for option: round and rectangle. Round air duct working can be connected up to the air supply inlet directly; while the rectangle one needs to be connected with a transition air duct to air supply inlet, and separate to the air diffuser. Pick up the selected air distributor or diffuser to meet the application requirements.

Return Air and Supply Air Direction supply air supply air return air supply air Drawings for piping connector and its dimension (unit: mm): supply air ￠ air outlet fresh air inlet Notes: • Do not close all air outlet of indoor unit when start to run the unit to avoid the frost of evaporator. • To ensure the thickness of insulation material and no leakage allowed. • Fresh air shall be less than 20%.
Installation of MDB-T Series Indoor Unit To mount the MDS050~060T in ceiling. With the air outlet flange close to the unit bottom, when the unit is mounted in ceiling, the piping is simple and decreases the requirement for room height. After the installation, only the air inlet/outlet is exposed, as shown below.
Installation of MCM-T Series Indoor Unit To Check the Accessories are Ready To Install the Indoor Unit There are two types of installation. Make sure the hook can bear the unit weight in ceiling mounting; a slope for the drainage direction is a must both for ceiling/floor standing mounting; ensure there is enough space for maintenance around the unit.
