Function Description:
The Denali Aire Room Air Conditioner is designed to provide cooling and/or heating (for 3DANCH models) and air circulation for a single room. It is a window-mounted unit that can be operated via a control panel on the unit itself or a remote control. The air conditioner offers various modes of operation including Cool, Fan Only, Eco, and Heat (for specific models), along with adjustable fan speeds and temperature settings. It also includes features like a delay timer for scheduled operation and a sleep mode for energy efficiency during sleeping hours.

Usage Features:
- Control Panel & Remote Control: The unit can be controlled using touchpads on the air conditioner's control panel or a dedicated remote control. Lights below the touchpads indicate selected settings.
- Power On/Off: A "Power" pad turns the unit on and off.
- Temperature Control:
- "Temp and Delay Increase +" / "Decrease –" pads adjust the set temperature or delay time.
- Temperature can be set in Cool, ECO, or Heat mode.
- Range: 64°F to 86°F in 1°F increments.
- Modes:
- Cool Mode: Provides cooling. Can be set with Auto, High, Med, or Low fan speeds.
- Fan Only Mode: Circulates and filters air without cooling. Fan speed can be set to High, Med, or Low. No temperature setting is entered in this mode.
- Eco Mode: Controls the fan to cycle on and off with the compressor, potentially leading to wider room temperature variations. An "OFF" setting allows the fan to run continuously while the compressor cycles.
- Heat Mode: (Available on 3DANCH18K & 3DANCH24K models only) Provides heating. Can be set with Auto, High, Med, or Low fan speeds.
- Fan Speed Control: "Fan Speed" pad allows selection of Auto, Low, Med, or High fan speeds in Cool, ECO, or Heat modes, and High, Med, or Low in Fan Only mode.
- Delay Pad:
- Delay ON: When the unit is off, it can be set to automatically turn on in 1 to 24 hours at previous mode and fan settings.
- Delay OFF: When the unit is on, it can be set to automatically turn off in 1 to 24 hours.
- Adjustable in 1-hour intervals using Increase/Decrease pads.
- Sleep Mode (Unit Panel Only):
- Gradually changes settings over an 8-hour period for energy efficiency.
- Available in COOL and FAN ONLY settings.
- In FAN ONLY, fan stays at LOW speed for 8 hours, then unit turns off.
- In COOL mode, fan stays at LOW speed for 8 hours. Set point raises 2°F after 30 minutes, then another 2°F after 30 minutes, remaining for 7 hours, then unit turns off.
- Any button press exits Sleep mode.
- Filter Reset Pad: Notifies user to clean the air filter after 250 hours of operation. Pressing the pad after cleaning resets the timer and turns off the indicator light.
- Air Direction: Louvers can be adjusted left/right and tilted up/down to direct airflow.
- Control Panel Lights On/Off Feature: Lights on the control panel turn off after one minute of inactivity. Pressing any pad reactivates them. This feature can be toggled on/off by pressing and holding the SLEEP pad for 5 seconds.
- Remote Control Range: Up to 20 feet, requires direct line of sight to the unit's signal receiver.
Maintenance Features:
- Grille and Case Cleaning: Turn off and unplug the unit before cleaning. Use warm water and mild detergent. Avoid bleach or abrasives.
- Air Filter Cleaning:
- Should be checked and cleaned at least every 30 days.
- To remove, pull down tabs on top corners of the grille.
- Clean with warm, soapy water, rinse, and air dry. Do not use a dishwasher.
- Can also be vacuumed with a hose adapter.
- Operating without a filter is cautioned against as it reduces performance.
- Outdoor Coils: Should be checked regularly for dirt/soot. Professional cleaning may be required. Coils can be cleaned with water or special dissolvent for copper coils.
- Drain Plug: The unit is equipped with a slinger blade to scoop water from the drain pan onto the coils for better efficiency. Water may collect in the base pan during high humidity and drip outside. The drain plug can be removed for quicker drainage, but this may reduce cooling and energy efficiency. Drilling holes in the unit is strictly prohibited as it voids warranty and can cause damage.
- Battery Replacement: Slide down the back cover of the remote control, insert 2 AAA batteries matching polarity, and slide the cover back up. Remove batteries from packaging before use.
- Power Cord Test/Reset: The power cord's current interrupter device should be tested periodically by pressing TEST, then RESET. Discontinue use if it malfunctions.
- General Safety: Use only for intended purpose. Proper installation is crucial. Never unplug by pulling the cord; always grip the plug firmly. Replace frayed/damaged power cords immediately. Unplug before cleaning. Do not store or use combustible materials near the unit. Receptacle must match the plug; consult a qualified electrician if needed.
- Flammable Refrigerant Warning: Contains flammable refrigerant. Do not use means to accelerate defrosting or cleaning other than manufacturer-recommended methods. Do not store in rooms with continuously operating ignition sources. Do not pierce or burn refrigerant tubing. Keep ventilation openings clear. Handle with care to avoid damaging refrigerant tubing. Do not drill holes. Maintenance/cleaning/service must be performed by trained technicians qualified in flammable refrigerants. Dispose of the unit according to Federal and Local Regulations.
- Extension Cords: DO NOT use extension cords, surge protectors, or multi-outlet adapters with this air conditioner.
- Grounding: Do not cut or remove the third (ground) prong. Do not use adapter plugs. Ensure the wall outlet is properly grounded by a qualified electrician. The unit should be plugged into its own individual electrical outlet with a matching voltage rating.
- Chemical Burn Hazard (Batteries): Keep batteries away from children. Swallowed batteries can cause severe internal burns and death. Secure battery compartment. Seek immediate medical attention if batteries are swallowed. Dispose of batteries properly.
- Prohibited Installation: DO NOT install this window air conditioner inside a wall sleeve or through a wall. This voids the warranty and can cause operational failure, airflow obstruction, water leakage, and electrical hazards. Ensure all air vents are unobstructed.
