Read Before Using
Incorrect usage may cause serious damage or injury.
WARNING
CAUTION
DO NOT insert fingers, rods, or other objects into the air inlet or outlet. This could cause injury,
since the fan may be rotating at high speeds.
DO NOT use flammable sprays such as hair spray, lacquer or paint near the unit, as this could
cause fire and/or an explosion.
DO NOT operate the unit in places near or around combustible gases. Emitted gas may collect
around the unit and cause an explosion.
DO NOT allow children to play with the air conditioner. Children must be supervised around
the unit at all times.
DO NOT operate the unit in a room where it could be exposed to excessive amounts of water,
such as a bathroom or laundry room. Exposure to excessive water amounts can cause the
electrical components to short circuit.
DO NOT expose your body directly to direct cool airflow from the unit for a prolonged period
of time.
1. If the unit operates abnormally (emits strange noises or a burning a smell), immediately turn off the
unit and disconnect the power in order to avoid electric shock, fire, and/or injury. Call your local
dealer, or MRCOOL®tech support at (270) 366-0457, for further assistance.
2. If the air conditioner is used together with burners or other heating devices, thoroughly ventilate
the room in order to avoid an oxygen deficiency.
3. In certain functional environments (such as kitchens and server rooms etc.), the use of specially
designed air-conditioning units is highly recommended.
4. This appliance can be used by children (8 years and older) and persons with reduced physical, sensory
or mental capabilities, or lack of experience and knowledge if they have been given instruction
concerning the use of the appliance and understand the hazards involved.
WARNING FOR PRODUCT USE
!
Safety Precautions
The symbols below are used throughout this manual to indicate instructions that should be
followed closely or actions that should be avoided to prevent death, injury, and/or property damage.
This symbol indicates ignoring instructions may cause bodily injury, damage
to the unit, or other surrounding property.
This symbol indicates ignoring instructions may cause death or serious injury.
This symbol indicates that you should NEVER perform the indicated action.
WARNING FOR CLEANING & MAINTENANCE
DO NOT clean the unit with excessive amounts of water.
DO NOT clean unit with combustible cleaning agents, as these could cause deformation and/or
fire.
1. Turn off the device and disconnect the power before cleaning. Failure to do this could result in
electrical shock.
2. Children should not be allowed to play with the appliance or perform cleaning and user maintenance.
Safety Precautions
****ELECTRICAL WORK MUST BE COMPLETED BY A QUALIFIED ELECTRICAL TECHNICIAN****
DO NOT share the power supply with other appliances. An improper or insufficient power
supply could cause fire and/or electrical shock.
DO NOT modify the length of the power supply, or use an extension cord to power the unit.
DO NOT pull the power cord to unplug the unit. Hold the plug firmly and pull it from the outlet.
Pulling directly on the cord could damage it, which can lead to fire or electric shock.
1. The product must be properly grounded during installation or electrical shock could occur.
2. Appropriate wiring standards, regulations, and the installation manual must be followed for all
electrical work.
3. If connecting power to fixed wiring, the following must be incorporated within it, in accordance with
the wiring rules; an all-pole disconnection device (which has at least 3 mm of clearances in all poles),
and have a leakage current that may exceed 10 mA, the residual current device (RCD) having a rated
residual operating current not exceeding 30 mA, all must be present.
4. For all electrical work, fuse the specified cables. Connect cables tightly and clamp them securely to
prevent external forces from damaging the terminal. Improper electrical connections could overheat,
causing fire and/or electrical shock.
5. All electrical connections must be made according to the Electrical Connection Diagram located on the
panels of the indoor and outdoor units.
6. All wiring must be properly arranged to ensure that the control board cover can close properly. If the
control board cover is not properly closed, it can lead to corrosion and cause the connection points on
the terminal to heat up, catch fire, or cause electrical shock.
7. Only use the specified power cord. If the power cord is damaged, it must be replaced by the
manufacturer, its service agent, or a similarly qualified technician in order to avoid a hazard.
8. Keep the power plug clean. Remove any dust or grime that accumulates around the plug as these
could cause electric shock and/or fire.
ELECTRICAL WARNINGS
WARNING FOR PRODUCT INSTALLATION
Page 4mrcool.com
The air conditioner’s circuit board (PCB) is designed with a fuse to provide overcurrent protection.
The specifications of the fuse are printed on the circuit board.
EXAMPLE: T3.15AL/250VAC,T5AL/250VAC, T3.15A/250VAC, T5A/250VAC, T20A/250VAC
(for <24,000 Btu/h unit), T30A/250VAC (for >24,000 Btu/h unit), etc.
NOTE: For units with R32 or R290 refrigerant, only the blast-proof ceramic fuse can be used.
TAKE NOTE OF FUSE SPECIFICATIONS
DO NOT install the unit in a location that may be exposed to combustible gas leaks. If
combustible gas accumulates around the unit, it could cause fire.
DO NOT turn on the power until the installation and all work has been completed.
DO NOT install a unit equipped with an auxiliary electric heater within 3 ft (1 m) of any
combustible materials.
1. Installation must be performed by an authorized dealer or specialist. An improper installation can
cause water leakage, electric shock, and/or fire.
2. Installation must be performed according to the installation instructions. Improper installation
could cause water leakage, electrical shock, fire, and could void the warranty. (In North America,
installation must be performed in accordance with the requirements of NEC and CEC by authorized
personnel only.)
3. Contact an authorized service technician for repair or maintenance of this unit. This appliance should
be installed in accordance with national wiring regulations.

Note about Fluorinated Gases:
1. This unit contains fluorinated greenhouse gases.
2. For specific information on the type of gas and the amount, please refer to the relevant label on
the unit itself.
3. Service, maintenance, and repair of this unit must be performed by a certified technician.
4. Product un-installation and recycling must be performed by a certified technician.
5. For equipment that contains fluorinated greenhouse gases in quantities of 5 tonnes of CO2
equivalent or more, but less than 50 tonnes of CO2equivalent, and has a leak-detection system
installed, it must be checked for leaks at least every 24 months.
6. Keeping a record of all leak checks for the lifetime of the unit is strongly recommended.
CAUTION
DO NOT allow the air conditioner to operate for extended periods of time with the doors or
windows open, or in very high humidity.
DO NOT operate the unit with wet hands, as this could cause electric shock.
DO NOT use this device for any other purpose than its intended use.
DO NOT climb onto or place objects on top of the outdoor unit.
1. Turn off the air conditioner and disconnect the power if it is not going to be used for an extended
period of time.
2. Turn off and unplug the unit during storms.
3. Ensure that condensate water can drain smoothly from the unit.
WARNING FOR PRODUCT INSTALLATION (Continued)
4. Only use the included accessories, parts, and specified parts for installation. Using non-standard
parts can cause water leakage, electrical shock, fire, and/or failure of the unit.
5. Install the unit in a firm location that can support the unit’s weight. If the location cannot support the
unit’s weight, or the installation is not done properly, the unit may drop and cause serious injury and
damage.
6. Install the drainage piping according to the instructions in this manual. Improper drainage could
cause water damage to your home and/or property.
7. When moving or relocating the air conditioner, consult experienced service technicians for
disconnection and re-installation of the unit.
8. For detailed information of how to install the indoor and outdoor units to their respective supports,
please refer to the indoor unit installation and outdoor unit installation sections of this manual.
9. Excessive Weight Hazard: Use two or more people when moving and installing the unit. Failure to do
this could result in personal injury.
