Case 5, Pit/Solid Wall Installation
Pit installations can cause operating problems and great care should be exercised if they are
to be used on an installation. Recirculation and restriction can both occur. A solid wall
surrounding a unit is substantially the same as a pit and the data presented here should be
used.
Steel grating is sometimes used to cover a pit to prevent accidental falls or trips into the pit.
The grating material and installation design must be strong enough to prevent such accidents,
yet provide abundant open area or serious recirculation problems will occur. Have any pit
installation reviewed by McQuay application engineers prior to installation to make sure it
has sufficient air-flow characteristics. The installation design engineer must approve the
work to avoid the risk of accident.
