Installation:
- The appliance comes with an air exhaust duct, window exhaust adapter, and baffle plate for installation.
- The air exhaust duct should be extended and screwed into the connector.
- The connector is then screwed into the plastic window connector.
- Finally, the connector of the air exhaust duct is connected to the unit.
- It is recommended to place the unit near a window or French window and ensure the air hose has clearance.
Maintenance Features
Regular maintenance is crucial for the appliance's longevity and efficient operation.
Appliance Maintenance:
- Cut off power supply: Always disconnect from power before maintenance.
- Wipe with a soft and dry cloth: Clean the appliance with a soft, damp cloth (water temperature below 40°C). For very dirty appliances, use a dry and soft cloth with a neutral detergent.
- Never use volatile substances: Avoid gasoline, polishing powder, or chemical cleaners.
- Never sprinkle water onto the main unit: This can cause electrical shock.
Air Filter Maintenance:
- Clean the air filter every two weeks: Or more frequently in dusty environments.
- Stop the appliance and remove the air filter: Pull out the filter from the back of the unit.
- Clean and reinstall the air filter: Wash it with a solution of detergent in lukewarm water. After cleaning, dry it in a shaded and cool place, then reinstall.
Maintenance after using:
- Pull out the primary and secondary rubber plug of the drain port to drain the water.
- Keep the appliance running with the fan on for half a day during a sunny day to dry the appliance inside and prevent mold.
- Stop the appliance, pull out the power supply plug, then take out the batteries of the remote controller and store the appliance properly.
- Clean the air filter and reinstall it.
- Remove the air hoses and store them properly, and cover the hole tightly.
Troubleshooting and Solutions:
- Does not run: Check if the protector trip or fuse is blown, wait 3 minutes for the protector device to reset, check if batteries in the remote controller are exhausted, and if the plug is properly plugged in.
- Runs for a short while only: Check if the set temperature is close to room temperature, if the air outlet is blocked by obstacle.
- Runs but not cooling: Check if the door or window is open, if there is another appliance heat-working, if the air filter is dirty, if the air outlet or intake is blocked, or if the set temperature is too high.
- Water leak during moving: Drain the condensate before moving, avoid water leakage.
- Does not run and water full indicator "E4": Pull out the rubber plug to drain water.
- Machine fails to start up: Power supply failure (plug not plugged, plug or socket damaged, fuse broken). Solutions include plugging in, replacing the power cord or socket, and replacing the fuse.
- Machine automatically stops: TIMING shut down or set temperature reached. Restart or wait for auto-switch.
- No cold air under COOLING mode: Room temperature lower than set temperature, machine enters into anti-frost protection. This is a normal phenomenon; the machine will auto-switch while the room temperature is higher than the set temperature. The machine will auto switch after anti-frost protection is over.
- LED displays failure code "E2": Room temperature sensor fails or damaged. Replace the room temperature sensor.
- LED displays failure code "E3": The evaporator oil pipe sensor fails or damaged. Replace the evaporator coil pipe sensor.
- LED displays failure code "E4": Water-full warning. Drain out the water.
