Title: 370.011 Fan coils -42GW200-701C-installasjonsmanual.pdf
For winter operation with fresh air intake, an anti-freeze thermostat set at 2°C is recommended, with the bulb placed on the water outlet pipe, before the supplementary fan.The fresh air flow must be less than 10% of the total air flow, to avoid operating problems or eccessive noise. For higher air flow a "primary air kit" is available which uses the prepunched hole for air ducting to an adjacent room and a baffle so that the fresh air is introduced into the room through a diffuser.Air distribution to adjacent room • Remove the precut sheet metal (ref. 45) using a punch.. • With a pencil, trace a line on the polystyrene around the inside edges of the panel that was previously removed. Cut away the polystyrene with a knife, taking care not to damage the heat exchange coil.
