The NIBE SAM 42 is a supply air module designed to work in conjunction with an exhaust air heat pump from NIBE, providing a comprehensive solution for mechanical exhaust air and pre-heated supply air in a building. It is compatible with NIBE F370 and F750 heat pumps.
The primary function of the NIBE SAM 42 is to utilize the heat present in the building's ventilation air to warm up incoming outdoor air. This process involves the outdoor air being drawn into the supply air module through the house's ventilation system. Within the SAM 42, the air absorbs heat energy, leading to an increase in its temperature. A fan then blows this heated air into rooms equipped with supply air inlets, ensuring a comfortable indoor climate. The SAM 42 is connected to the heat pump, allowing its operational values to be monitored and read from the heat pump's display.
The NIBE SAM 42 is designed with user convenience in mind, offering several key features:
Regular maintenance of the NIBE SAM 42 is minimal after commissioning, but consistent checks are recommended to ensure optimal performance and longevity.
It is advisable to regularly check the installation. Should any unusual occurrences or malfunctions arise, the heat pump display will show corresponding alarm texts and messages.
The air filter in the SAM 42 is not designed for cleaning and must be replaced periodically. Replacement should occur at least once a year, though more frequent changes might be necessary depending on the air's particle content and other environmental factors. The main product's display will provide a reminder to check the filter, with a factory setting for this reminder every three months. This countdown resets if the main product's power is interrupted.
To replace the filter:
Even if the filter appears clean, it accumulates dirt that can impair its efficiency, making annual replacement crucial. New filters can be ordered through a NIBE dealer.
To vent the SAM 42, open one vent valve at a time until water emerges, then close the valve. This process helps remove air from the heating medium system, which can be a cause of low supply air temperature.
In most cases, a compatible NIBE heat pump will detect and indicate malfunctions that could lead to disturbances in comfort, displaying alarms and action instructions. If an operational interference is not shown, the following basic actions and tips can be used:
