AcuAir Hygienic Air Units
Figure 2: AcuAir system-to-wall spacing requirements
Note:
• This is a generic unit layout shown. Consult the order specic
unit layout drawing before beginning site engineering.
• The minimum distance from the exhaust fan housing to any
sensitive object in the discharge air stream is 2 fan diameters.
Any closer and the object may be damaged. The minimum
suggested distance from the exhaust fan housing to an airow
obstruction (such as a wall) is 4 fan diameters for a single fan
and 6 fan diameters for two exhaust fans.
• The minimum distance from an access door in the open posi-
tion to an object is the door width, which is 24 in. plus 8 in.
• The minimum distance from any electrical enclosure to an ob-
ject is 48 in.. The installation of the AcuAir
®
unit must be in ac-
cordance with the codes of the authorities having jurisdiction.
• The AcuAir
®
hygienic unit has sections under both positive and
negative pressure with respect to ambient during normal op-
eration. When piping the individual drain pan outlets to a com-
mon drain line, AcuAir
®
suggests individual p-traps. The piping
design must take into account the pressure inside the specic
section and the elevation required to create the necessary trap.
See Figure 31 for drain piping suggestions.
• Consult the refrigeration contractor as to how much space is
required for the coil piping. Leave a minimum walk space of 30
in. between the nal eld piping to any object.
• As with any large equipment placement, ensure consideration
of maintenance, service, and part or component replacement
when designing space for the unit.
