Features of product: SILENCE+ LIME MINI PUMP- ASPEN - FP3322/5

In an air conditioning or heat pump installation, condensate must be drained continuously to prevent overflow and safety shutdowns. The challenge is often related to the location of the indoor unit: in the absence of sufficient slope, a lift pump becomes essential.
Aspen pumps are valued for their compactness and installation flexibility. Depending on the model, the pump can be integrated into a trough, false ceiling, or near the indoor unit. The goal is to achieve stable drainage while maintaining discreet integration and accessible maintenance.
A successful installation relies on proper sizing and suitable components:
Pump and suction module: ensure the lifting of condensate with consistent flow and appropriate discharge height.
Level detection: sensor or float, reliable triggering to avoid water accumulation.
Installation accessories: kits, brackets, fittings, and pipes to secure sealing and minimize vibrations.
Measure the required lift height, discharge length, and identify the actual location of the pump (unit, trough, ceiling). A properly sized model reduces noise, limits cycles, and improves durability.
Technical Tip: ensure simple access for maintenance (cleaning, sensor check): this is a key point to avoid failures related to clogging.
