short circuit.
Do not store the unit in a humid basement or expose it to rain or water.
Make sure the installation base and lifting are robust and reliable;
Insecure installation of the base may cause the air conditioner to fall, leading to an accident. Take
into full consideration the effects of strong winds, typhoons and earthquakes, and reinforce the
installation.
Check whether the drain pipe can drain the water smoothly.
Improper installation of the pipeline may lead to water leakage, damaging furniture, electric
appliances, and the carpet.
After installation, check whether the refrigerant is leaking.
Do not install the product in a location where there is a danger of flammable gas leaks.
In the event of leakage of combustible gas, the combustible gas surrounding the indoor unit may
cause a fire.
Install an air filter of 30-80 mesh/inch at the return air grille to filter dust in the air and keep
the air diffuser clean and free from dirt blockage.
CAUTION
Keep the indoor unit, outdoor unit, power supply cable, and connecting wires at least 1m away from the high-
power radio equipment, to prevent electromagnetic interference and noise. For some electromagnetic waves, it
is not enough to prevent noise even at a distance of more than 1m.
In a room equipped with fluorescent lamps (rectifier type or fast start type), the signal transmission distance of
the remote controller (wireless) may not reach the predetermined value. Install the indoor unit as far away from
the fluorescent lamp as possible.
Do not touch the fins of the heat exchanger, as this could cause injury.
For safety, please dispose of the packing materials properly.
Nails and other packaging materials may cause personal injury or other risks. Tear up the plastic packaging bag and
dispose of it properly to prevent children from playing with it, leading to suffocation.
Do not cut off the power supply immediately after the indoor unit stops running.
Some parts of the indoor unit like the valve body and water pump are still in operation. Please wait for at least 5 minutes
before cutting off the power supply. Otherwise, water leakage and other faults may occur.
If the length and direction of the air inlet/outlet panel or connecting duct have been changed, complete the
following settings on the controller before use the air conditioner again: (For details, see the Application
Control section)
Reset the initial static pressure on the controller or perform a trial run on the outdoor unit (performed by the installer),
and set the current state as a reference state for the unit to determine the filter status.
If the above operations are not performed, then the unit may not detect the state of the filter accurately.
For evaporating units and condensing units, the instructions or markings shall include a wording to assure
that the maximum operating pressure is considered when connecting to any condenser unit or evaporator unit.
For evaporating units, condensing units and condenser units, the instructions or markings shall include
refrigerant charging instructions.
A warning to assure that partial units shall only be connected to an appliance suitable for the same refrigerant.
This unit is a partial unit air conditioner, complying with partial unit requirements of this International Standard,
and must only be connected to other units that have been confirmed as complying to corresponding partial unit
requirements of this International Standard.
The electrical interfaces shall be specified with purpose, voltage, current, and safety class of construction.
The SELV connection points, if provided, are to be clearly indicated in the instructions.
The connection point should be marked with the “read the instructions” symbol per ISO 7000-0790 (2004-01)
and the Class III symbol according to IEC 60417-5180 (2003-02).
For R32 Refrigerant only.
This unit is equipped with a refrigerant leak detector for safety. To be effective, the unit must be electrically powered at
all times after installation, other than when servicing.
If any supplemental unit is employed to detect leaked refrigerant, such unit shall also apply this marking or be
accompanied by such instructions.
