Dimension of air conditioner
Dimension of sleeve assembly (optional)
- To avoid vibration and noise, make sure the unit is installed securely and firmly.
- When installing the sleeve & Front grille, make certain there is nothing within 21” back & front of sleeve & front grille, that would interfere with heat radiation and exhaust air flow
- An insulation strip must be attached.
- After assembly of sleeve & front grille, the gap should be over 20” from both sleeve & grille. (See the figure 1.)
- Take out the insulation strip from the upper packing.
- Attach the insulation strip onto the rear upper side of the wall sleeve.
CAUTION
- Require 2 people to lift the air conditioner, it is HEAVY
- Before installation, Check the insulation on the inner side of the sleeve. If there is no insulation, place the insulation.
- Check the bottom corner's joint gap of the sleeve, If there is, fill the gap with putty.

OPERATION
Before Operation
Preparing for Operation
- Contact an installation specialist for installation. This is NOT a do-it-yourself project.
- Plug in the power plug properly.
- Use a dedicated circuit.
- Do not use an extension cord. Consult a professional installer or electrician.
- Do not start/stop operation by plugging/unplugging the power cord.
- If the cord/plug is damaged, replace it with only an authorized replacement part.
Usage
- Being exposed to direct airflow for an extended period of time could be hazardous to your health. Do not expose occupants, pets, or plants to direct airflow for extended periods of time. In other words, don't sit in the draft.
- Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves or other heating devices.
- Do not use this air conditioner for non-specified special purposes (e.g. preserving precision devices, food, pets, plants, and art objects). Such usage could damage the items.
Cleaning and Maintenance
- Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling sharp metal edges.
- Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading to possible electric shock.
- When cleaning the unit, first make sure that the power and breaker are turned off. The fan rotates at a very high speed during operation. There is a possibility of injury if the unitʼs power is accidentally triggered on while cleaning inner parts of the unit.
MAINTENANCE
Air Filter
Check the air filter at least twice a month to see if cleaning is necessary. Trapped particles in the filter can build up and block the airflow, reducing cooling capacity and causing an accumulation of frost on the evaporator
Cleaning the Air Filter
- Remove the air filter from the front grille assembly by pulling the air filter up slightly.
- Wash the filter using lukewarm water below 40 °C (104 °F).
- Gently shake the excess water from the filter and replace.
Cleaning the Front Grille and discharge air grille
- The Front Grille and discharge air grille can be cleaned with a mild soap or detergent. Under no circumstances should hydrocarbon based cleaners (e.g. acetone, benzene, naphtha, gasoline, etc.) be used to clean the front or air grilles.
- Use care when cleaning the control area. Do not use an excessively wet cleaning cloth.
Vent Filter
Before cleaning the vent filter, disconnect power to the unit by unplugging the power cord at the wall outlet or subbase, or disconnect power at the fuse box or circuit breaker. If unit is operated with vent door closed, the vent filter does not need to be cleaned.
Cleaning the Vent Filter
- Remove the front grille as described in front grille Removal.
- Remove the 4 screws securing the unit to the wall sleeve with a Phillips-Head screwdriver.
- Slide the unit out of the wall sleeve far enough so that the vent filter is accessible. Remove the shipping screw from the ventilation door.
- Remove the vent filter by unscrewing the two screws at the top of the filter and gently pulling the filter away from the partition panel.
- Wash the filter using lukewarm water below 40 °C (104 °F). Reinstall the filter by reattaching the hook to the bottom of the vent door and replacing the two screws, slide the unit back into the wall sleeve, secure it in place with 4 screws and reinstall the front grille.
