Installation instructions
Damage to the unit if the line feedthrough to the terminal box is pre-installed.
Line feedthroughs may be damaged if the connection line is pulled or the unit is lifted by the line.
- Do not pull connection lines or lift the unit using the lines.
Wall-mounted fans DZQ .. Ex e / t and DZS .. Ex e / t
- For permanent installation in wall or ceiling with sufficient load-bearing capacity.
- Any installation position can be selected.
- Can be switched to ventilation or air extraction.
- Only mount unit on a level wall/ceiling surface to avoid warping of the wall plate or wall ring.
DZR .. duct fans Ex e / t
- For permanent installation in ducts with folded spiral-seams ducts suited to the unit type (nominal size).
- Mounting on a wall, ceiling or bracket of sufficient load-bearing capacity.
- Any installation position can be selected.
- Can be switched to ventilation or air extraction.
- To avoid the transmission of vibrations to the duct system, we recommend mounting type EL-Ex and ELAEx flexible couplings, FU mounting foot and GP vibration dampers from MAICO.
DZD .. roof fans Ex e / t
- They may be used on roofs (flat, inclined, corrugated or trapezoidal roofs), ceilings or brackets with sufficient load-bearing capacity.
- Horizontal installation position required. Horizontal air outlet direction.
- Can be switched to ventilation or air extraction.
- Can be mounted with roof flashing on suitable roof socket or surface, e.g. with MAICO roof socket SO.., SDS.. or SOWT..
- If connecting to ventilation ducts, folded spiral-seams ducts with flexible couplings, feet and vibration dampers are specified. These prevent the transmission of vibrations to the duct system.
