2.3 Assessing the RV Roof for Installation
Assessing the RV roof is a critical step before installing the Coleman Mach 15. Ensure the roof is structurally sound and free from damage. Measure the roof opening to confirm it matches the unit’s dimensions, typically requiring a maximum of 15×15 inches. If no existing vent is available, mark the area for cutting, ensuring proper alignment and sealing. Check for obstructions like vents, antennas, or skylights that may interfere. Verify the roof material (metal, fiberglass, or rubber) and prepare appropriate sealants. Ensure the roof can support the unit’s weight and consider reinforcements if needed. A stable, level surface is essential for proper installation and performance.
Installation Process
The Coleman Mach 15 installation involves mounting the unit, connecting electrical components, and setting up ducting. Follow the manual carefully, ensuring all steps are completed safely and correctly.
3.1 Electrical Connections and Wiring
Begin by turning off the RV’s power supply for safety. Locate the electrical box and identify the wires. Connect the white compressor wire to the capacitor’s C terminal. Next, splice the white wire to the brown ICM soft start wire. Ensure the red ICM soft start wire connects to the previous white compressor wire location. Use a voltage meter to verify connections and check for any short circuits. Secure all wires properly to avoid loose connections. Refer to the wiring diagram in the Coleman Mach 15 manual for precise instructions. Proper electrical connections are crucial for the unit’s efficient operation and safety.
3.2 Mounting the Coleman Mach 15 on the RV Roof
Begin by ensuring the RV roof is clean and dry. Use a ladder or stepstool to access the roof safely. Remove the cover from the air conditioner unit and set it aside. Locate the roof vent opening or prepare a new one if necessary. Ensure the opening does not exceed 15×15 inches; if it does, fabricate a mounting frame to reduce the size. Align the Coleman Mach 15 unit with the opening, ensuring it is level. Secure the unit using the provided mounting hardware, tightening bolts firmly. Apply sealant around the edges to prevent leaks. Double-check the alignment and tighten all connections to ensure stability and proper fit.
3.3 Ducting and Ventilation Setup
Connect the ducting system to the Coleman Mach 15’s supply vents, ensuring proper alignment and secure connections. Turn the vent adapters 90 degrees and press slightly toward the AC adapter to collapse the ducting. Align the ducting with the ceiling vents or existing RV ductwork, ensuring a snug fit. Use approved materials to seal any gaps or connections. Once installed, test the system by running the AC unit to verify airflow. Proper ducting ensures efficient cooling and prevents air leaks, which can reduce performance. Always follow the manufacturer’s guidelines for ducting configuration to maintain optimal function and warranty validity.
