Refer to the complete manual (043-6127-2 series) for detailed safety guidelines.
Unit Dimensions and Specifications (15″W x 30.12″H x 18.39″D)
Understanding your Garrison portable air conditioner’s physical characteristics is crucial for proper placement and installation. The unit measures 15 inches in width (W), 30.12 inches in height (H), and 18.39 inches in depth (D). These dimensions are vital when determining suitable locations and ensuring adequate ventilation around the unit.
Refer to model numbers like MPPHB-05CRN8-BC or 043-6127-2 for specific details. The manual details these specifications for optimal performance. Proper spacing around the unit, as outlined in the manual, is essential for efficient cooling. Confirm these dimensions before purchasing window kits or planning installation to avoid compatibility issues. Accurate measurements ensure a secure and effective setup.

Installation and Setup
Proper installation is key for efficient cooling! Carefully unpack your Garrison unit, inspect for damage, and follow the manual for setup guidance.
Unpacking and Initial Inspection
Carefully remove your new Garrison portable air conditioner from all packaging materials. A thorough initial inspection is crucial to ensure no damage occurred during shipping. Verify all components are present, referencing the parts list within this manual – this includes the unit itself, the exhaust hose, the window kit, and any included remote control.
Inspect the unit’s exterior for dents, scratches, or other visible damage. Check the power cord for any cuts or fraying. Ensure the exhaust hose is intact and free of kinks. If any damage is detected, do not operate the unit and immediately contact Garrison Customer Support at 1-888-498-0439. Retain all original packaging materials in case a return or exchange is necessary. Proper documentation of any initial damage will expedite the resolution process.
Setting Up the Exhaust Hose
Proper exhaust hose installation is vital for efficient cooling. Connect one end of the exhaust hose to the designated port on the back of the Garrison air conditioner unit. Ensure a secure, airtight connection – twisting the hose clockwise until it clicks into place is often required.
The other end of the hose connects to the window kit (detailed in the next section). Avoid bending or kinking the hose, as this restricts airflow and reduces cooling performance. The hose should be as straight as possible. Regularly inspect the hose connection points for looseness. A compromised seal will allow hot air to re-enter the room, negating the cooling effect. Maintaining a proper exhaust setup is key to maximizing your unit’s efficiency.
Window Kit Installation
Begin by selecting a suitable window for installation, ensuring it can be securely closed around the window kit. Assemble the window kit components according to the included diagrams – typically involving adjustable panels to fit various window sizes. Insert the assembled kit into the window opening, extending it sufficiently to accommodate the exhaust hose connection.
Secure the kit firmly in place, utilizing the provided brackets and screws. Proper sealing is crucial; use the foam strips included with the kit to fill any gaps between the kit and the window frame. Connect the exhaust hose to the designated port on the window kit. Verify a snug fit to prevent hot air from re-entering the room. A well-installed window kit maximizes cooling efficiency.

Operation and Control
Effortlessly manage your comfort with intuitive controls! Adjust settings for desired temperature, fan speed, and operation modes for optimal cooling performance.

Powering On and Basic Operation
Initial Startup: Before powering on, ensure the unit is correctly installed with the exhaust hose properly connected and the window kit securely in place. Plug the Garrison air conditioner into a grounded electrical outlet. Press the power button – typically indicated by a power symbol – to initiate operation. The unit may undergo a brief self-check sequence.
Mode Selection: Utilize the control panel to select your desired operating mode. Common modes include Cool, Fan, and Dry (Dehumidify). The ‘Cool’ mode activates the compressor for active cooling, while ‘Fan’ circulates air without cooling. ‘Dry’ mode reduces humidity. Refer to the control panel display for mode indicators.
Indicator Lights: Pay attention to the indicator lights on the control panel. These lights provide feedback on the unit’s status, such as power on, cooling operation, and filter check reminders. Consult the manual for specific light meanings.
Temperature Control and Settings (62-95°F Optimal Range)

Setting the Temperature: Your Garrison portable air conditioner allows precise temperature control within the 62-95°F (16-35°C) optimal range. Use the “Temp Up” and “Temp Down” buttons on the control panel, or the remote control if provided, to adjust the desired temperature. The current set temperature will be displayed on the unit’s digital display.
Cooling Performance: For efficient cooling, start with a lower temperature setting and gradually increase it until you achieve your comfort level. Remember that the unit’s cooling capacity is affected by room size, insulation, and external temperature. Avoid setting the temperature drastically lower than the room temperature for optimal energy efficiency.
Auto Mode: Some models feature an “Auto” mode, which automatically adjusts the fan speed and cooling output to maintain the set temperature. This mode provides convenient, hands-free operation.
Fan Speed Adjustment
Controlling Airflow: Your Garrison portable air conditioner offers multiple fan speed settings to customize airflow and cooling intensity. Typically, these include Low, Medium, and High settings, selectable via buttons on the control panel or the remote control. Experiment with different speeds to find the balance between comfort and energy efficiency.
Low Speed: Ideal for gentle cooling and quiet operation, suitable for smaller rooms or maintaining a consistent temperature. Medium Speed: Provides a balanced airflow for general cooling needs. High Speed: Delivers maximum airflow for rapid cooling, best for larger spaces or when quick temperature reduction is desired.

Auto Fan: Certain models include an “Auto” fan setting, which automatically adjusts the fan speed based on the cooling demand. This optimizes performance and minimizes noise.

Maintenance and Troubleshooting
Keep it Cool: Regular cleaning of the air filter and proper water drainage are crucial for maintaining peak performance and longevity of your Garrison unit.
Cleaning the Air Filter
Maintaining optimal air quality and cooling efficiency requires regular air filter cleaning. It’s recommended to inspect the filter at least every two weeks, and clean it as needed, depending on usage and environmental conditions. A clogged filter restricts airflow, reducing cooling performance and potentially damaging the unit.
To clean the filter: First, ensure the air conditioner is powered off and unplugged. Locate the filter access panel – consult your model’s specific diagrams within the full manual (043-6127-2, etc.). Gently remove the air filter. Vacuum the filter to remove loose dust and debris. For a more thorough cleaning, wash the filter with mild soap and lukewarm water. Rinse completely and allow it to dry completely before reinstalling. Never operate the unit without a dry filter! Reinstall the clean, dry filter securely into its designated slot.
Draining Water from the Unit
Your Garrison portable air conditioner collects condensation during operation, which must be periodically drained to maintain efficiency and prevent potential water damage. The frequency of draining depends on humidity levels and usage. Most models feature a drain plug or a removable water tank – refer to your specific model number (MPPHB-05CRN8-BC, 043-6127-2) manual for precise location.
To drain: Power off and unplug the unit. Locate the drain plug or remove the water tank. If using a drain plug, position a container underneath to catch the water; Carefully remove the plug, allowing the water to drain completely. Replace the plug securely. If using a tank, carefully remove, empty, and rinse the tank before reinstalling. Ensure the tank is properly seated to prevent leaks. Regularly draining prevents mold growth and ensures optimal performance, as detailed in the comprehensive Garrison manual.
Common Issues and Solutions
Encountering issues with your Garrison portable air conditioner? Here are some common problems and their solutions. Unit not cooling: Ensure the exhaust hose is properly connected and the window kit is sealed correctly. Check the air filter for blockage – a dirty filter restricts airflow. Water leakage: Verify the drain plug is securely fastened or the water tank is correctly installed.
Error codes: Consult your model’s (043-6127-2, MPPHB-05CRN8-BC) manual for specific code meanings. Unit is noisy: Ensure the unit is on a level surface. If problems persist, contact Garrison Customer Support at 1-888-498-0439. Always unplug the unit before attempting any troubleshooting.
