Installation instructions
Location
The air conditioner should be placed on a hard and level surface strong enough to support the unit. The unit has casters and it should only be rolled on smooth, flat surfaces. Use caution when rolling on carpet surfaces. Do not attempt to roll the unit over objects.
Never place any obstacles around the air inlet or outlet and allow at least 20 inch of clearance for efficient air-conditioning.
Exhaust hose Installation
When you use this air conditioner unit, hot air must be exhausted out of the room to complete the air exchange of the condenser. When the unit is operating in DEHUMIDIFYING or FAN only mode, no exhaust is required.
- Pull out about 6” of one end of the hoses.
- Attach the hose connectors to the hoses by turning clockwise.
- Align the slots on the hose connector to the tabs on the air intake / outlet and snap the hose to the unit.
- Only extend the exhaust hoses to the necessary length. We do not recommend extending the exhaust hose more than 9' long. Additional 4’ e xhaust hose sold separately.
- If you are interested in purchasing optional accessories, please contact [email protected] for retail sales information.

Cooling mode
- In this mode, the air conditioner cools and dehumidifies the room. To activate this function mode, press the Mode Control button until the GREEN indicator comes on. When the cooling mode is set, the compressor will start in approximately 3 minutes.
NOTE: In cooling mode, hot air is exhausted from the outdoor exhaust port and the exhaust hose must be connected to exhaust out the hot air. - The temperature setting range of this air conditioner is from 61°F to 89°F. To set the temperature, press the + or - buttons. This air conditioner has a 5°F temperature cushion which if the set temperature is within 5°F of the ambient temperature, the unit runs on fan only mode. This saves energy and prolongs the life of the compressor of the air conditioner. Once the set temperature is achieved, the fan runs continuously.
- To set the fan speed, press the Fan Speed button. In cooling mode, the difference in noise level between the 3 fan speeds is not very noticeable when the compressor is on. Try setting the unit to Fan only mode, you should be able to hear the difference between high and low fan speed settings.
Dehumidifying mode
- In this mode, the air conditioner only dehumidifies the room, the compressor will activate intermittently depending on the ambient temperature and the fan speed is set to LOW. To activate this function mode, press the Mode Control button until the PURPLE indicator comes on. Please note that when switching function mode, there will be an approximately 3 minute transition time. In dehumidifying mode, do not connect the exhaust hose and let the warm air return to the room.
If room temperature is higher than 77°F, the fan speed can be adjusted. If room temperature is lower than 77°F, the fan speed is set at Low.
NOTE: When using the Dehumidifying mode, the air exhaust hose should not be vented to the outside. If the warm air is exhausted to the outside, cooling may occur. Additionally, you must manually drain the water from the unit.
Remove the upper drain stopper to setup continuous drainage if needed. Water can be drained to a container or to a floor drain using a garden hose (not included.)
Fan only mode
- In this mode, only the fan of the air conditioner runs and circulates the air in the room. To activate this function mode, press the Mode Control button until the BLUE indicator comes on. In this function mode, the temperature cannot be set. Subsequently, set the desired fan speed by pressing the Fan Speed button. Fan Only mode requires that the exhaust hose be removed. NOTE: The unit does not need to be vented in Fan Only mode.
Heating mode
- In this mode, the air conditioner heats the room. To activate this function mode, press the Mode Control button until the RED indicator comes on. When the heating mode is set, the compressor will start in approximately 3-5 minutes.
NOTE: In heating mode, cold air is exhausted from the outdoor exhaust port and the exhaust hose must be connected to exhaust out the cold air.
If outside temperature is lower than inside temperature, air intake hose should be blocked and unit will take in air from the air filter. - The temperature setting range of this air conditioner is from 61°F to 77°F. To set the temperature, press the + or - buttons. Once the set temperature is achieved, the compressor and the fan will stop. NOTE: This unit uses heat pump for heating and the heating mode does not work when temperature is below 45F.
- To set the fan speed, press the Fan Speed button. In heating mode, the difference in noise level between the 3 fan speeds is not very noticeable when the compressor is on. Try setting the unit to Fan only mode, you should be able to hear the difference between high and low fan speed settings.
