Connection Of The Unit To Electric Network; Start-Up Recommendations; System Protection; Pre-Startup Recomendations Of The Unit (In The Presence Of The Enduser) - Salda AMBERAIR COMPACT RH Series Mounting And Installation Instruction

• In order to reduce air loss in the system, the air ducts and profile parts should be of class C and higher. Their catalog can be found in our
website.
• If air handling unit is installed in heated premises, outdoor and exhaust air ducts must be insulated in order to avoid heat loses and condensing.
If AHU is installed outdoors, it's recommended to insulate all the air ducts.
• It is recommended to maintain a distance of up to 8 meters between air intake and air exhaust ducts. Air supplying system should be installed
further from potential air pollution sources.
• Use holders while installing air ducts next to the ventilation equipment. They suppress vibration and ensure a firm installation of various system
parts.
• Necessary holders can be found in our catalog or website.
• A common mistake is that air ducts are attached to improper airflow connection. On the ventilation equipment there are signs, indicating the air
duct to be connected. Before starting the system carefully check whether the work was performed properly.
