Installation recommendation

• One air supply vent must be installed in every 20 m². Supply valves needs to be installed in each room (bedroom, living room). From other rooms (kitchen, toilets, bathrooms and lobby) stale air extracts through vents.
• The installation location should be chosen as high as possible to allow the air to warm up as it descends.
