Main Features
General
The new MCW-DA FCUs are specically designed to satisfy high cooling capacity application requirement. They
represent one of the most cost effective solutions to provide a comfortable environment for both commercial and
residential applications. Their quiet operation, compact dimensions and particularly low height, make units ideal
for ceiling concealed installation even in buildings with narrow ceiling spaces. Units are standard supplied with
soundproofed suction plenum and air lter. Centrifugal fans, with forward-curved blades, are statically and dynamically
balanced and driven by single-phase motors with three speeds.They feature elegant design, advanced structure,
high efciency, low noise, convenient installation and low maintenance. They are widely used in houses, shopping
malls, hospitals and ofce etc.
Higher Cooling Capacity in High Delta T Application
These units are particularly suitable for high External Static Pressure and high Delta T(chilled water temperature
difference)applications.Theycandelivery more cooling capacityinhighDeltaTconditions with the speciallydesigned
fans & motors, coils and excellent combination of them.
Low Chilled Water Pressure Drop
In order to meet even the most demanding customer requirements, the new FCUs adopt the most reasonable and
optimized water circuit design and utilize the National accredited thermal test room to guarantee both the perfect
performance and a low chilled water pressure drop.
Extra High Air Flow Volume at High ESP
These units can supply more air ow at high ESP. 11 models of MCW-DA cover an air ow range from 200 to 1600
CFM at medium speed with ESP of 75Pa.
High Efciency and Energy Saving
A boundary layer lm of air adhering to the n surface will insulate the n surface and severely reduces the heat
exchange efciency. McQuay slit designed and HYDROPHILIC BLUE FIN eliminates this boundary layer of air and
creates continuous turbulence for best heat exchange efciency.
Flexibility
Units are available with left or right hand water connections, which can be easily switched in the eld by changing the
positions of the fan-motor assembly and the supply air ange assembly if required.
Compact Design
The low height design makes this fan coil unit series ideally suited for the tight ceiling concealed installation
Low Noise Design
Enlarged fan wheels design allows lower fan speed selection for the same external static pressure and airow
requirement. Thereby noise level is signicantly reduced.
Powerful Selection Software
Powerful select software makes various conditions selection precise and cost saving.

Installation
Receiving
All units leaving the factory have been inspected to ensure the shipment of high quality products and reasonable
means are utilized to properly pack the fan coil units to protect them in transit.
Carefully inspect all shipments immediately upon delivery. When damage is visible, note this fact on the carrier’s
freight bill and request that the carrier send a representative to inspect the damage. This may be done by telephone
or in person, but should always be conrmed in writing.
The shipment should be unpacked in the presence of the agent so that the damage or loss can be determined. The
carrier’s agent will make an inspection report and a copy will be given to the consignee for forwarding to the carrier
with a formal claim.
Location

g.1 for the minimum distance between the unit and obstacle.
2. In case of installation in free blow, the unit must be installed at a minimum height of 2.5m to avoid contact with the
appliance.
3. Please ensure enough space for piping connection and electrical wiring.
4. Please make sure that the hanging rods can support weight of the unit.
Installation
1. The unit is designed for concealed ceiling installation.
2. There are holes on the top of the unit for hanging. Please refer to Fig.1. Fig.2 and Fig.3.
3. Make sure that the top of the unit is level.
Insulation
1. The insulation design and materials should be complying with local and national codes and regulations.
2. Chilled water pipes and all parts on the pipes should be insulated.
