  • How do I install a Dometic BRISK 2 air conditioner?

    The installation of the Dometic BRISK 2 air conditioner involves several steps that should only be carried out by qualified personnel:

    1. Roof preparation: This includes selecting a flat and level area on the vehicle roof, ensuring the roof inclination does not exceed 15°, and checking for sufficient roof support.
    2. Opening requirements: Carefully mark and cut the required roof opening. If an existing opening is not within the specified dimensions (346 mm x 346 mm to 352 mm x 352 mm), it must be resized.
    3. Electrical wiring: Route a copper, with ground, 240VAC supply wire from the time delay fuse or circuit breaker box to the roof opening. Ensure the power supply is disconnected before making connections.
    4. Placing the unit: Lift and place the unit over the prepared opening, using the gasket on the unit as a guide. Do not slide the unit to avoid damage to the gasket.
    5. Completing installation: Check and adjust the gasket alignment. Install the duct divider, ensuring the foil side faces the rear of the unit. Secure the air distribution box and ceiling template using mounting bolts and screws. Fix the return air sensor and feed the communication wire.
    6. Final connections: Make connections for the 240VAC supply to the rooftop unit, ensuring they are well insulated and excess wire is tucked away. Align the air distribution box with the ceiling template and install the front and rear vent doors, along with the filter in the return air grille.

What causes the unit to come on run 1 min or so shut off 30 seconds later start back up

A possible cause for the Dometic unit running for 1 minute and then shutting off for 30 seconds before restarting could be a freeze-up condition or a faulty electrical connection. If the unit freezes up, it may shut down to prevent damage. Running the fan on low speed can contribute to freeze-up. Another possibility is a bad electrical connection affecting components like the thermocouple or solenoid, which can interrupt normal operation. Cleaning and securing electrical connections and checking fuses may help resolve the issue.
