Features
Superior Performance
• Extensive research work coupled with world leading manufacturing technology has caused the new
design with superb performance and high efficiency.
• Stringent quality control and component selection ensure performance and reliability. Major components
are rigorously tested and qualified prior to usage in the machine.
• Every machine design has passed many hours of rigorous testing to ensure the machine reliability,
durability and quality.
• Scroll compressor brings much higher energy efficiency. High efficiency heat exchanger ensures
strenuous exertion of equipment capacity. Dedicated water pump particularly designed for air
conditioning engineering is operating steadily with minimum vibration and noise.
For MAC080C/CR to MAC150C/CR
• These units are designed with double independent refrigerating system, greater energy saving is
achieved by only one compressor on duty under part load condition.
Simple To Operate
• The MAChine is complete with intelligent microprocessor controller and temperature sensor to
automatically control the operation to its optimum condition, making it very simple to operate. All
temperature settings are finished before shipment. The only thing for user to do is to start the unit by
pressing the ON/OFF button after ensuring unit proper function, then every operation can be
automatically performed by the unit itself.
• Either wireless remote controller or wired remote controller is ready for choosing to meet satisfactory
indoor unit control, both compatible with the unit.
Friendly Installation
• The machine has been designed with friendly installation in mind such that no refrigeration charging or
copper pipe brazing is required on site.
• Threaded fitting is provided for easy water piping connection on site.
• Water inlet and outlet are provided on both sides of the machine such that piping can be connected on
either side of the machine.
• Rust resistant PP-R composite water pipe with good insulation property and high durability is standard
parts in the machine.
• Stainless steel taper threaded fittings target convenient disassembly or assembly.
• For MAC080C/CR to MAC150C/CR, expansion chamber, water pump and water flow switches are
already equipped in this compact packaged unit with top air discharge. In addition, McQuay provides
accessory hydraulic kit with water storage tank, auto water fill valve, auto air vent valve, auto pressure
relief valve and strainer integrated in, aiming at ensuring high efficiency and safe operation. For
MAC030C/CR to MAC070C/CR, expansion chamber is equipped in the accessory hydraulic kit instead
of being incorporated in unit.
For MAC030C/CR to MAC070C/CR
• Both front and rear sides can be served as access to performing wiring and maintenance.
Safety Control
• Protection devices such as dual pressure protection and overload protection etc. is provided to ensure
unit operating within safety condition range. The microprocessor-based controller automatically directs
system on or off by processing the water temperature feedback. If the water temperature falls to
unacceptable low point, the controller automatically shut off the system to prevent hydraulic system
internal freeze for unit safety operation. Meanwhile, the microprocessor-based controller automatically
monitors every component operating status and malfunction, and feedback it to indoor controller to
greatly ease the work of status monitor and troubleshooting.
All Weather
• The cabinet is made of electro galvanized mild steel sheet, coated with baked polyester power to ensure
the units extra durability in all climates against sun, rain, wind corrosion.
• Space saving (small footprint) design of the machine eliminates large installation area requirement, no
need for equipment room.
• The machine uses high quality parts to ensure durability in various climate conditions.
Page 3
Simple To Maintain
• The simple design of the machine allows for maximum serviceability. All components are with reach of
the maintenance personnel upon open up of the servicing panel. If emergency shutoff occurs, the
microprocessor-based controller will indicates the fault cause to quicken and ease troubleshooting.
Three Color Appearance Available (For MAC030C/CR to MAC070C/CR)
• There are three optional colors-blue, green and red available to be easily choose to meet customers’
requirements, so the unit can be harmonically blend into building overall look.

General Specification
Compressor
McQuay Mini Chillers are equipped with highly efficient, reliable and silence scroll compressor, double for
MAC080C(R) to MAC150C(R), one for MAC030C/CR to MAC070C/CR.
Air-Cooler Condenser
The air-cooled condenser coil consists of staggered rows of 3/8’’ O.D. seamless copper tube, mechanically
expanded into die formed aluminum fins to ensure optimum heat exchange capability.
Condenser Fan Motor
To achieve the high air change requirement, the unit is equip with the high air flow propeller fan. The fan is
direct driven by weatherproof motor to ensure reliable continuos operation.
Evaporator
The heat exchanger is made of stainless steel plates closely arranged and brazed together to ensure high
heat exchange efficiency. The complete heat exchanger is insulated with thermal insulation closed cell
rubber foam to give optimum thermal insulation.
Refrigerant Circuit
The refrigerant circuit is factory brazed and evacuated before accurately charged with R22 to ensure
optimum operating requirement. To ensure flawless continuous operation, each refrigerant circuit is
equipped with a carefully sized capillary tube.
Additional Safety Protection
The units are equipped with intelligently designed safety control to ensure continuous safe operation. High
and low pressure switch is provided to prevent the compressor damage resulting from both abnormally high
discharge head pressure or low pressure due to insufficient gas. The compressors are provided with crank
case heater to prevent liquid migration during the off cycle and also to ease the start up of the unit.
The standard electronic controller provides accurate water temperature control in the circuit by closely
monitoring and reacting to the input from the water entering temperature, water leaving temperature and
ambient air temperature.
Flow switch is provided in the unit to protect against damage to the water pump.
During abnormal condition, the electronic controller will turn the unit off and the then display the faulty of
operation. (See Troubleshooting sheet)
Page 5
Controller
The controller accomplishes its control function with its built-in microprocessor. The two parameters,
temperature and water flow rate, have been factory set before shipment, no need for users to reset them.
The controller will display unit operation status to favor specialized personnel to monitor unit operating
condition for maintenance if necessary. When the system is cut off due to malfunction, the controller will
display the corresponding failure code for easy trouble shooting.
Installation and connection
After removing the terminal box cover, you will find the indoor controller, 20m long indoor connection wire,
and 1.5m long maintenance connection wire. Decide a suitable place for installing the indoor controller, you
can either mount it on wall or embed it in wall. Open the back cover of the indoor controller, plug one end of
the indoor connection wire to the CN3 connector located on controller, insert another end to the CN6
connector located on PCB, then assembly the terminal box cover back, now this work is finished.
Please ensure the 1.5m maintenance connection wire being in good keep for later maintenance by
specialized personnel.
