MOUNTING RECOMMENDATIONS FOR SUPPLY AND EXHAUST DIFFUSERS
• When selecting supply and exhaust grilles and disk valves it is necessary to take into account the following factors:
• Noise level.
• Air flow.
• Expansion of the air jet.
Mounting recommendations for supply grilles and disk valves
• Depending on the air jet spread the supply grilles and disk valves can be mounted on the ceiling, on the wall, or in the floor
near inner or outer walls.
• If the supply grilles are mounted in the floor it is recommended to install a floor heating system to avoid the effect of “a local
cold air lake”.
• The distance to the occupied space should be not less than 1 m.
• Supplying air to the occupied area may cause draughts. To avoid this, it is necessary to provide low air jet speed. The temperature
of the air jet should be close to the air temperature in the room.
• It is forbidden to mount supply grilles and disk valves behind the curtains, wardrobes, beams.
• The distance from supply disk valves to the corners of a room should be not less than 500 mm in order to avoid uncomfortable
conditions caused by an air jet.
• Supply grilles can be positioned closer, depending on the type of air jet.
Mounting recommendations for exhaust grilles and air disk valves
• Exhaust grilles and disk valves should be mounted on the ceiling or on the wall as high as possible.
• The distance to the corners of a room should be not less than 200 mm.
• Exhaust ventilation elements must be installed close to the source of contaminants such as moisture and odours.
• At the same time, it is not recommended to install exhaust grilles and disk valves above a bath or a shower.
• It is not recommended to install exhaust ventilation elements directly above radiators. It can lead to unnecessary heat losses.
• Do not install the exhaust ventilation element directly over the cooker in the kitchen, as this will result in grease entering the
ventilation system.
• If the air in the room contains a lot of sprayed grease particles, it is recommended to use exhaust elements with built-in
replaceable filters.
