Ambient Temperature Range for Unit Operation

Introduction to Inverter Technology

As pioneers in the air comfort space, Whynter is introducing next-generation technology currently used only in high-efficiency ductless mini-split air conditioners. The Inverter technology will be featured in Whynter's NEX line of portable air conditioners. By utilizing this much more efficient technology, Whynter's Inverter variable-speed system allows the compressor to optimize efficiency and power consumption together, while maintaining a specified output.

This allows for a much quieter operation and significantly reduced energy consumption. The Inverter technology system potentially reduces energy usage by more than 40% while the new hose-in-hose design delivers more than double the cooling output. Below are the advantages of inverter technology:

• At least 40% - 50% cheaper to run as it consumes less power
• Quicker to achieve desired temperature
• Quieter operation
• No temperature fluctuations
• No voltage peaks from compressor

Hose-in-Hose Cooling Setup

The innovative two-hose in one design and the sealed bottom structure ensure no heat leakage. This cooling setup extracts and exhausts air from the outdoor, so the indoor space reaches an independent and balanced cool air circulation. As a result, the entire room can be cooled down quickly and effectively.

Technical Data

What Should I Look For When Purchasing a Portable Air Conditioner?

The right air conditioner helps you cool a room efficiently. An undersized unit won't cool adequately while one that's too large will not remove enough humidity, leaving the air feeling damp. To find the proper air conditioner, determine the square footage of the room you want to cool by multiplying the room length by its width. You also need to know the air conditioner's BTU (British Thermal Unit) rating, which indicates the amount of heat it can remove from a room. Why is the cooling capacity lower on newer models than on older units? A higher number means more cooling power for a larger room. (Be sure you are comparing only newer models to each other- older models may appear to have a higher capacity, but are actually the same). Be sure to "size up" if your portable air conditioner will be placed in a very sunny room, in a kitchen, or in a room with high ceilings. After you've found the right cooling capacity for your room, you can look at other features.

Why is the Cooling Capacity Lower on Newer Models Than Older Models?

Federal regulations require manufacturers to calculate cooling capacity based on a specific test procedure, which was changed just this year. Models manufactured before 2017 were tested under a different procedure and cooling capacity is measured differently than in previous models. So, while the BTUs may be lower, the actual cooling capacity of the air conditioners has not changed.

What is SACC?

SACC is the representative value of Seasonally Adjusted Cooling Capacity, in Btu/h, as determined in accordance with the DOE test procedure at title 10 Code of Federal Regulations (CFR) 430, subpart B, appendix CC and applicable sampling plans.

Accessories

Window Kit Installation

Adjustable Window Slider Option

1. Measure the window opening where the window kit will be installed.
2. Assemble as many sliders as necessary to fit the window. If the window opening is less than the minimum length of a single slider, use the slider that has the hole in it and cut it to the correct length. Make sure not to cut the end that has the hole as this is necessary to attach the exhaust hose adapter.
3. Use the window slider bolts to secure the window sliders at the correct length.

Hoses Connector Modules (For Sliding Window)

Assemble the exhaust adapter module for sliding windows using the exhaust connector screw as shown. The window slider is eccentric so the exhaust adapter must be installed away from the wall.

Note: For vertical installation, exhaust hose connector module B can be omitted.

1. Rotate the exhaust hose gently backwards.
2. Pull out the exhaust hose away from the wall.

Hose-in-hose

NOTE: To ensure proper functioning, DO NOT overextend or bend the hose. Make sure that there is 20" of clearance around the air outlet of the exhaust hose in order for the exhaust system to work properly. All illustrations in this manual are for explanation purposes only. Your air conditioner may be slightly different. The actual shape shall prevail.

Hung Window or Sliding Window Installation

1. Cut adhesive foam seals A and B to the correct lengths and attach them to the window frame as shown.
2. Insert the window slider kit into the window opening and close the window to secure it in place.
3. Cut the non-adhesive foam seal C to match the width or height of the window and insert it between the panes of glass as shown to prevent outside air from entering the window.
4. If desired, install the security bracket with 2 screws as shown.
5. For a hung window, attach the air outlet adapter onto the exhaust hose and rotate it 90° to secure it in place. For a sliding window, attach the exhaust adapter onto the exhaust hose.

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 button until the DRY indicator light is displayed. Please note that when switching function mode, there will be an approximately 3 minute transition time. In dehumidifying mode, the exhaust hose does not need to be vented. If the exhaust hose is vented, the room will be cooled as it dehumidifies. To prevent cooling, remove the exhaust hose from the window kit and allow the warm air from the rear to be re-circulated into 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 dehumidifying mode, venting the exhaust hose to the outside is not required. If vented, the warm air is exhausted to the outside and cooling within the room may occur. Additionally, if the exhaust hose is not vented, the unit may require more frequent draining. Also, the air conditioner does not have a humidistat in which a specific humidity level can be set.

Automatic Mode

When you set the air conditioner in AUTO mode, it will automatically select cooling or fan only operation depending on what temperature you have selected and the room temperature is close to the unit. The fan speed is automatically selected and cannot be changed. To operate the unit in Auto mode when the unit is on, press the MODE button until the AUTO indicator light comes on.
