    Why is there insufficient air flow and pressure in my Sabiana T-EP?
    • B
      blackdaleAug 9, 2025
      If the Sabiana Heating System's air flow is insufficient, and the pressure is low, it could be due to several reasons: * The ducted system and/or extraction points might be clogged, requiring cleaning of both the system and the intake point. * Frost may have formed on the exchanger; consider assessing the use of a preheating coil. * Pressure drops may have been underestimated; double-check the operating point on the recovery unit's graph. * The rotation speed might be insufficient; check and recalibrate the fans' operating voltage. * The filter could be dirty; clean or replace the filter media, always using original filter media to maintain the unit's efficiency. * The heat exchanger might be clogged; clean the mouth of the heat exchanger.

    What to do if the air flow decreases in my Sabiana T-EP Heating System after some time?

      Casey WilliamsAug 14, 2025
      If the air flow decreases after a period of operation in your Sabiana Heating System, it could be due to pressure drops upstream or downstream of the fan. Check the connections and casing of the unit and restore the initial conditions. Another possible cause is a damaged impeller. Inspect the impeller and replace it with an original spare part if necessary.

      Jeff WilsonAug 20, 2025
      If you notice leaking or dripping water from the casing of your Sabiana Heating System, it could be due to a clogged siphon. Clean the siphon to resolve this issue. Alternatively, the siphon might be missing or improperly fitted. In this case, set up a siphon to standard.

      Nathan DavisAug 27, 2025
      If the performance of the heat exchanger in your Sabiana Heating System is insufficient, it could be due to a build-up of dirt on the fins of the heat exchanger. Clean the heat exchanger to resolve this issue.

    How to fix a Sabiana T-EP Heating System that starts up with difficulty?
    • N
      Nicole CannonSep 1, 2025
      If your Sabiana Heating System unit has difficulty starting up, check the power supply voltage against the voltage specified on the engine’s rating plate.
