board cover is not fixed perfectly, it can cause overheating at the terminal connection point, fire, or
electrical shock.
• If the supply cord is damaged, it must be replaced by the manufacturer, service agent, or other qualified
person in order to avoid a hazard.
• An all-pole disconnection switch with a contact separation of at least 0.12in in all poles should be
connected in fixed wiring.
• When completing piping connection, take proper precautions to avoid air substances entering the
refrigeration cycle. Otherwise, it can cause lower capacity, abnormally high pressure in the refrigeration
cycle, explosion, and/or injury.
• Do not modify the length of the power supply cord, use an extension cord, or share the single outlet with
any other electrical appliances. Otherwise, it can cause fire or electrical shock.
• If the refrigerant leaks during installation, ventilate the area immediately. Toxic gas may be produced if
the refrigerant comes in contact with fire.
• The temperature of refrigerant circuit will be high, please keep the interconnection cable away from the
copper tube.
• After completing the installation work, check that the refrigerant does not leak. Toxic gas may be
produced if the refrigerant leaks into the room and comes into contact with a source of fire, such as a
heater, stove or cooker.

Outdoor Unit Installation 5
Page 15 mrcool.com
Installation Location Figure of Body Size
The outdoor unit should be installed in a location that
meets the following requirements:
• There is enough room for installation and
maintenance.
• The air outlet and the air inlet are not impeded.
• It must be a dry and well ventilated place.
• The support is horizontal, flat, and can stand the
weight of the outdoor unit.
• Noise will not disturb your neighbors.
• It is easy to install the connecting pipes or cables.
• Determine the air outlet direction where the
discharged air is not blocked.
• There is no danger of fire due to leakage of
inflammable gas.
• The piping length between the outdoor unit and the
indoor unit may not exceed the allowable piping
length.
• In the case that the installation place is exposed to
strong wind such as a seaside, make sure the fan
operating properly by putting the unit lengthwise
along the wall or using a dust shield.(Refer to Fig.5.3)
• If possible, do not install the unit where it is exposed
to direct sunlight.
• If necessary, install a blind that does not interfere
with the air flow.
• During heating mode, water drains off the outdoor
unit. Position the drainage appropriately from the
drain hole to an appropriate place where it will not
interfere with other people or equipment.
• Select the position where it will not be subject to
snow drifts, accumulation of leaves or other seasonal
debris. If unavoidable, please cover it with a shelter.
• Locate the outdoor unit as close to the indoor unit as
possible.
• If possible, please remove any nearby obstacles that
could create poor performance from low air
circulation or vibration.
• The minimum distance between the outdoor unit and
obstacles described in the installation chart does not
mean that the same is applicable to the situation of
an airtight room. Leave open two of the three
directions (M,N,P) (Refer to Fig.5-5)
