Stainless steel taper threaded fittings target convenient disassembly or assembly. For M4AC080C/CR to M4AC150C/CR, expansion chamber, water pump and water flow switch are already equipped in this compact packaged unit with top air discharge. Both front and rear sides can be served as access to performing wiring and maintenance.
General Specification Compressor McQuay Mini Chillers M4AC080C(R) to M4AC150C(R) are equipped with highly efficient, reliable and silence scroll compressors. 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.

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 Installation Notice This equipment must be installed by your dealer or authorized McQuay qualified personnel, and the installation must satisfy all the following requirements. Location In order to achieve unit maximum capacity and long lifeoperation, the location selection should fulfill the following requirements: a) The location must be well ventilated, so that air can be drawn in and discharge out efficiently.
Page 21
For M4AC080C(R) to M4AC150C(R), if good ventilation cannot be guaranteed when unit being installed indoors, it is advisable to induce discharge air from air outlet to outdoors by installing duct which is as short as possible. e) Support unit base up to create a space above foundation for ensuring free water drainage, and the stable foundation with level surface must be sufficiently durable against the unit weight.
Delivery and Lifting When transporting the unit, it is advisable to use forklift or crane to do this work. Only the wooden skid base is allowed to be served as the weight-supporter. When hoisting, please keep the unit stable and without slope, meanwhile, be sure to avoid lifting cable contact with side heat exchanger, panel and unit’...
Both chilled water inlet and outlet port are external taper thread connections. When performing water pipe connection, use gripping pliers to fix the unit connections to avoid the reserved connections on unit being directly suffered from revolving torque when fastening.

If auxiliary electric heater or auxiliary gas heater installation is required, please do installation after thoroughly reading corresponding manual. Carry out the electrical connection according to the diagram below so that achieve their automatic on/off governed by the unit controller. In addition, contact with local McQuay service representative for performing trail startup.
McQuay designers have given full consideration to make servicing convenient during unit development. After opening service panel, both servicing and maintenance can be easily carried out. Under normal environment, the only work needed is checking the return air way and cleaning the heat exchange surface regularly at month or season interval decided on operating condition.
When other code is displayed, please consult specialized personnel. See detailed indoor controller operation in corresponding instruction manual. Schematic Diagrams Cooling Only Version (M4AC080C/100C/120C/150C) C hi l l ed W at er I n C hi l l ed W at er O ut...
