DRAINAGE
Manual drainage:
- When the machine stops after the water is full, please unplug the power plug.
Notes: Please move the machine carefully, so as not to spill the water in 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, the water will automatically flow into the water container.
Notes:
- Keep the water plug properly.
- During drainage, the body can be tilted slightly backwards.
- If the water container cannot hold all the water, before the water container is full, stuff the water outlet with the water plug as soon as possible to prevent water from flowing to the floor or the carpet.
- When the water is discharged, stuff the water plug.
Notes: Restart the machine after the water plug and drainage cover are installed, otherwise condensate water of the machine will flow to the floor or the carpet.
Diagram illustrating the manual drainage process, showing the unit with a water container placed below its side water outlet.
Continuous drainage
The self-evaporating system uses the collected water to cool the condenser coils for better efficient performance. There is no need to empty the drainage tank in cooling operation except in drying operation and high humidity conditions. The condensate water evaporates at the condenser and is evacuated through the exhaust hose.
For continuous operation or unattended operating in drying operation, please connect the attached drain hose to the unit. Condensate water can automatically flow into a bucket or drain by gravity. Condensate water of the machine will flow to the floor or the carpet.
- Switch off the unit before operating.
- Remove the plug of the water outlet opening, and keep it in a safe area.
- Securely and properly connect the drain hose and make sure it is not kinked and clear of obstruction.
- Place the outlet of hose over a drain or bucket and ensure that water could freely flow out of the unit.
- Do not submerge the end of hose into water; otherwise it can cause "Air Lock" in the hose.
Diagram illustrating continuous drainage, showing the unit with a drain hose connected to its outlet, leading into a bucket.
To avoid water spillage:
- As the negative pressure of condensate drain pan is large, tilt the drain hose downward toward the floor. It is appropriate that the degree of inclination should exceed 20 degrees.
- Straighten the hose to avoid a trap existing in the hose.
6. CLEANING AND CARE
6.1. CLEANING THE AIR FILTER (every two weeks)
Dust collects on the filter and restricts the 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. The air filter is removable for easy cleaning. Do not operate the unit without an air filter, or the evaporator may be contaminated.
- Press POWER button to switch off the unit and unplug the power cord.
- Remove the filter mesh from the unit.
- Use a vacuum cleaner to suck dust from the filter.
- Turn the filter over and rinse the air filter under running water. Let the water run through the filter in the opposite direction of air flow. Set aside and allow the filter to air dry completely before reinstalling.
Pic1: Diagram showing how to switch off the unit and remove the two air filters. Pic2: Diagram showing how to rinse the air filter under running water.
Warning!!! Do not touch the evaporator surface with bare-hand, or could cause injury of your fingers.
6.2. CLEANING UP OF REFRIGERANT
General Measures:
- Gas/vapor is heavier than air. 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 area.
- Do not get in eyes, on skin, or on clothing. Do not breathe vapors or gas.
- Prevent entry to sewers and public waters.
- Stop the source of the release, if safe to do so. Consider the use of water spray to disperse vapors.
- Isolate the area until gas has dispersed. Ventilate and gas test area before entering. Contact competent authorities after a spill.
