Safety Precautions

mrcool.com

DO NOT install the unit within 3 ft (1 m) of combustible materials if the unit is equipped

with an auxiliary electric heater.

DO NOT install the unit in a location that may be exposed to combustible gases. If

combustible gas accumulates around the unit, it could cause ﬁre and/or an explosion.

DO NOT operate your air conditioner in a room where it could be exposed to excessive

amounts of water, such as a bathroom or laundry room. Too much exposure to water could

cause the electrical components to short circuit.

DO NOT put appendages or other objects into the air inlet or return grills.

DO NOT stop the appliance by directly cutting oﬀ the power. Turn oﬀ the unit ﬁrst.

DO NOT install the appliance in areas with either of the following:

oil smoke or volatile liquid, as plastic parts may deteriorate, adversely aﬀecting the

integrity and functionality of the appliance.

corrosive gas; as this may corrode copper piping and welds, adversely aﬀecting the

integrity and functionality of the appliance.

DO NOT force-dry the ﬁlter using an open ﬂame or blowers, as these could damage it.

DO NOT operate the air conditioner with wet hands.

DO NOT wash or sprinkle water on the air conditioner, otherwise malfunction or electric

shock will occur.

This appliance must be properly grounded during installation, or electrical shock could occur.

Install drainage piping according to the instructions in this manual. Improper drainage could

cause water damage to your home and property.

This appliance must be stored in a well ventilated area equal in size to the area speciﬁed for

operation. It must also be without a continuously operating open ﬂame (ex. an operating gas

appliance) and ignition sources (ex. an operating electric heater).

Use proper measures to protect the outdoor unit from rodents and other small animals that

could damage electrical components, causing the unit to malfunction.

If wired control (ex: a wall-mount thermostat) is to be used, it should be connected ﬁrst before

powering up the unit, otherwise it may not function properly.

Only use a soft dry cloth or, as necessary, a slightly wet cloth with neutral detergent to clean the

casing of this appliance.

Before operating the unit under low temperature, connect it to power for 8 hours. If it is

deactivated for a short time (ex: for one night), do not cut oﬀ the power. This is done in order to

protect the compressor.

If the unit is to be installed in a small space, please adopt protective measures to prevent the

concentration of refrigerant from exceeding the allowable safety limit; excessive refrigerant

leakage could lead to an explosion.

When installing or re-installing the air conditioner, please keep the refrigerant circuit away from

substances other than the speciﬁed refrigerant, such as air. Any presence of foreign substances

will cause an abnormal pressure change which could cause an explosion and/or personal injury.

Please adopt safety protection measures before touching the refrigerant pipe; otherwise injury

could occur.

Please select the properly-sized copper piping according to the requirements for pipe thickness.
