Safety Precautions
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 can damage it, which could lead to fire and/or electric shock.
DO NOT modify the length of the power supply or use an extension cord to power the unit.
DO NOT open or remove the unit’s panel while the unit is powered on. Touching the unit’s
internal components while the unit is powered on could lead to electric shock or injury from
moving parts such as the fan.
DO NOT spray any liquids onto the unit or allow any liquids to drip onto the unit.
1. Installation must be performed according to the installation instructions. Improper installation
could cause water leakage, electrical shock, fire, and could void the warranty.
2. 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 [phone], for further assistance.
3. In North America, service or repair must be performed in accordance with the requirements of NEC
and CEC (by authorized personnel or authority having jurisdiction only). Contact an authorized service
technician for repair or maintenance of the unit.
4. Only use the included accessories and specified parts for installation. Using non-standard parts can
cause water leakage, electrical shock, fire, and may cause the unit to fail.
5. Install the unit in a firm, stable location that can support its weight. If the installation location cannot
support the weight of the unit, it could fall and cause serious injury and/or damage.
6. Appropriate wiring standards, regulations, local codes, and the installation manual must be followed
for all electrical work.
7. 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.
8. 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.
9. All wiring must be properly arranged to ensure that the control board cover can close properly. If the
control board cover is not closed properly, it can lead to corrosion, which can cause the connection
points on the terminal to overheat, which could result in fire and/or electric shock.
10. In certain functional environments (such as kitchens and server rooms etc.), the use of specially
designed air-conditioning units is highly recommended.
11. If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or a similarly
qualified person in order to avoid a hazard.
12. 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. Children should not play
with the appliance. Cleaning and user maintenance should not be performed by children.
13. If the air conditioner is used together with burners or other heating devices, thoroughly ventilate
the room in order to avoid an oxygen deficiency.
14. Contact an authorized service technician for repair or maintenance of this unit.
15. Install drainage piping according to the instructions in this manual. Improper drainage may cause
water damage to your home and property.
16. When moving or relocating the air conditioner, consult experienced service technicians for
disconnection and re-installation of the unit.
