For Home Owners section in this Installation and Maintenance Instruction. FLM 40 is an exhaust air module. This means it can utilise the energy in the ventilation air. The energy is used to raise the temperature of the ingoing brine to the heat pump.
FLM 40 is an exhaust air module specially designed to combine recovery of mechanical exhaust air with an energy Extract air Exhaust air Avluft Frånluft collector in the ground or in rock. FLM 40 is designed to Extract air Exhaust air Ø 160 Ø 160 Ø...
For Home Owners Maintenance routines FLM 40 and its ventilation ducting require some regular maintenance where the following points should be checked: The numbers in brackets refer to the section “List of components”. Cleaning the air filter The exhaust air module’s air filter should be cleaned regu- larly (about 4-5 times a year) by taking it out and shaking off any dirt.
(the inner cover plate must then be dismantled). The water seal is maintained during filling. After using for a period of time dust and other particles can clog the water seal, consequently, you should check this regularly and clean when necessary. NIBE FLM 40...
Noise from the circulation pump or fan can be transfer- red to the brackets. Consequently, mount on an outside wall if possible. If it is not possible to mount FLM 40 on Handling an outside wall avoid a wall connecting to a bedroom or living-room.
Filling and venting the system The condensation water hose is routed directly to the floor FLM 40 is filled from the heat pump’s brine, see the Köldbärare in vid 0 °C drain or other water seal. Ensure that the end of the hose Installation and Maintenance instructions in question.
When installing on FIGHTER 1240/150, the space under Ø 160 Ø 160 FLM 40 is limited to 90 mm. This may mean that the pipe connections on FIGHTER 1240/1250 must be shortened. FLM 40 The brine is connected to FLM 40 as set out on the outline diagram.
When FLM 40 is placed directly above the heat pump the power supply can be connected to the heat pump’s termi- To externally start and stop the fan in FLM 40 remove the nal block. The connection plug must however be cut off.
Ventilation connection Ventilation flow Duct installation FLM 40 is connected so that all ventilation air, except for To prevent fan noise being transferred to the exhaust air the kitchen fan, passes the heat exchanger (62) in the devices, it may be a good idea to install a silencer in the exhaust air module.
