BEFORE YOU BEGIN

PRODUCT DESCRIPTION
Our powerful portable air conditioners serve as excellent cooling solutions for single rooms, creating a comfortable atmosphere in your space. Additionally, they feature ventilation and dehumidifying functions to circulate air and remove moisture. These self-contained systems do not require any permanent installation, allowing you to move them to the space where they are most needed. They are commonly used in kitchens, temporary residences, computer rooms, garages, and other places where installing an Outdoor Unit is impractical. The environmentally friendly R32 is used as the refrigerant. R32 has no damaging inﬂuence on the ozone layer (Ozone Depleting Potential – ODP), a negligible greenhouse eﬀect (Global Warming Potential – GWP), and is available worldwide. Due to its eﬃcient energy properties, R32 is highly suitable as a coolant for this application. Special precautions must be taken into consideration due to the coolant’s high ﬂammability.

SAFETY PRECAUTIONS ON SERVICING
Please follow these warnings when undertaking the following during the servicing of an appliance with R32.

Checks to the area
Prior to beginning work on systems containing ﬂammable refrigerants, safety checks are necessary to minimize the risk of ignition. Before conducting work on the refrigerating system, comply with the following precautions.

Work procedure
Work shall be undertaken under a controlled procedure to minimize the risk of ﬂammable gas or vapor being present during the work.

General work area
All maintenance staﬀ and others working in the local area shall be instructed on the nature of the work being carried out. Avoid working in conﬁned spaces. Section oﬀ the area around the workspace. Ensure that the conditions within the area have been made safe by controlling ﬂammable materials.

Checking for the presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to and during work to ensure the technician is aware of potentially ﬂammable atmos-pheres. Ensure that the leak detection equipment being used is suitable for ﬂammable refrigerants, i.e., no sparking, adequately sealed, or intrinsically safe.

Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate ﬁre extinguishing equipment shall be available at hand. Have a dry powder or CO2 ﬁre extinguisher adjacent to the charging area.

No ignition sources
No person carrying out work related to a refrigeration system that involves exposing any pipework containing or having contained ﬂammable refrigerant shall use any sources of ignition in a manner that may lead to the risk of ﬁre or explosion. Keep all possible ignition sources, including cigarette smoking, suﬃciently far away from the site of installation, repairing, removal, and disposal during which ﬂammable refrigerant can possibly be released into the surrounding space. Before work takes place, survey the area around the equipment to ensure there are no ﬂammable hazards or ignition risks. Display “No Smoking” signs.

Ventilated Area
Ensure that the area is open or adequately ventilated before breaking into the system or conducting any hot work. Maintain a degree of ventilation throughout the work period. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere.

Checks to the Refrigeration Equipment
When changing electrical components, ensure they are ﬁt for the purpose and to the correct speciﬁcations. Always follow the manufacturer’s maintenance and service guidelines. If in doubt, consult the manufacturer’s technical department for assistance.

The following checks shall be applied to installations using ﬂammable refrigerants:

The charge size is in accordance with the room size within which the refrigerant- containing parts are installed.
The ventilation machinery and outlets are operating adequately and are not obstructed.
If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant.
Ensure markings on the equipment remain visible and legible. Illegible markings and signs shall be corrected.
Refrigeration pipes or components are installed in a position where they are unlikely to be exposed to any substance that may corrode refrigerant-containing components, unless the components are constructed of materials inherently resistant to corrosion or suitably protected against corrosion.

Checks to Electrical Devices
Repair and maintenance of electrical components shall involve initial safety checks and component inspection procedures. If a fault exists that could compromise safety, no electrical supply shall be connected to the circuit until the fault is satisfactorily addressed. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be implemented. This should be reported to the equipment owner to ensure all parties are informed.

Initial safety checks shall include:

Discharging capacitors: this should be done in a safe manner to avoid the possibility of sparking.
Ensuring there are no live electrical components and that wiring is not exposed during charging, recovering, or purging the system.
Verifying continuity of earth bonding.

WARNING!

B. When the unit operates in the drying operation, once the coil temperature sensor senses the temperature of the evaporator is below 104°F and the diﬀerential temperature between coil temperature and room temperature is below 66°F after the compressor operates for 20 minutes, the unit starts defrosting for 5 minutes, and the power indicator blinks.

Overload Protection
In the event of a power loss, there is a 3-minute delay to protect the compressor before it restarts.

DRAINAGE

Manual Drainage

When the machine stops after the water is full, please unplug the power plug. Note: Move the machine carefully to avoid spilling water from the water pan at the bottom of the body.
Place the water container below the side water outlet behind the body.
Unplug the water plug, and the water will automatically ﬂow into the water container.

Notes

Keep the water plug properly.
During drainage, the body can be tilted slightly backward.
If the water container cannot hold all the water, before the water container is full, insert the water plug into the water outlet as soon as possible to prevent water from ﬂowing onto the ﬂoor or carpet.
When water is discharged, insert the water plug. Note: Restart the machine after the water plug and drainage cover are installed; otherwise, condensate water from the machine may ﬂow onto the ﬂoor or carpet.

Continuous Drainage
The self-evaporating system utilizes collected water to cool the condenser coils for better eﬃciency. There is no need to empty the drainage tank during cooling operation, except in drying operation and high humidity conditions. The condensate water evaporates at the condenser and is expelled through the exhaust hose. For continuous or unattended operation in drying mode, please connect the provided drain hose to the unit. Condensate water will automatically ﬂow into a bucket or drain by gravity.

Switch oﬀ the unit before operating.
Remove the plug from the water outlet opening and keep it in a safe area.
Securely and properly connect the drain hose, ensuring it is not kinked and clear of obstruction.
Place the hose outlet over a drain or bucket, ensuring that water can freely ﬂow out of the unit.
Do not submerge the end of the hose in water, as it can cause an “Air Lock” in the hose.

To Avoid Water Spillage

Due to the signiﬁcant negative pressure of the condensate drain pan, tilt the drain hose downward toward the ﬂoor. The appropriate degree of inclination should exceed 20 degrees.
Straighten the hose to prevent any traps from forming in the hose.

CLEANING AND CARE

CLEANING THE AIR FILTER (Every Two Weeks)
Dust collects on the ﬁlter and restricts airﬂow. The restricted airﬂow reduces the eﬃciency of the system, and if it becomes blocked, it can cause damage to the unit. The air ﬁlter requires regular cleaning and is removable for easy mainte-nance. Do not operate the unit without an air ﬁlter, or the evaporator may be contaminated.

Press the POWER button to switch oﬀ the unit and unplug the power cord.
Remove the ﬁlter mesh from the unit.
Use a vacuum cleaner to remove dust from the ﬁlter.
Turn the ﬁlter over and rinse it under running water. Let the water run through the ﬁlter in the opposite direction of airﬂow. Set aside and allow the ﬁlter to air dry completely before reinstalling.

Cleaning Procedure:

Switch off the unit and remove the air filters.
Rinse the air filter under running water.

Warning: Do not touch the evaporator surface with bare hands, as it could cause injury to your fingers.

CLEANING UP OF REFRIGERANT

General Measures

Gas/vapor is heavier than air and may accumulate in confined spaces, particularly at or below ground level.
Eliminate every possible source of ignition.
Use appropriate personal protection equipment (PPE).
Evacuate unnecessary personnel, isolate, and ventilate the area.
Do not get in the eyes, on the skin, or clothing. Do not breathe vapors or gas.
Prevent entry to sewers and public waters.
