APC NetworkAIR™ FM-DX 53
Guidelines for Installation
The NetworkAIR FM provides reliable, accurate temperature and humidity
control of computer rooms, laboratories, and other environments that
require close tolerance control. The unit incorporates the latest system
design innovations to provide you with optimum efficiency, reliability, and
accuracy of control.
The NetworkAIR FM system will provide years of trouble-free service,
when installed and maintained by technically qualified personnel.
Room preparation During the design of the room, consideration should be given to the
following factors: ease of entry for the system, floor-loading factors, and
accessibility of piping and wiring.
The room must be sealed with a vapor barrier to minimize migration of
moisture. Polyethylene film (plastic sheeting) is a good vapor barrier for
ceiling and wall applications. Rubber- or plastic-based paints should be
applied to concrete floors and walls. The room should be thoroughly
insulated to minimize thermal loads and make-up air (if required) should
be preconditioned to reduce additional temperature, filtration, and
moisture loads.
A room using a raised-floor plenum for air distribution should have at
least 9" (300 mm) of clear space between the false floor and sub-floor
for a finished floor height of 12" (380 mm). Pay special attention to the
location of pipe chases, electrical conduits and other obstructions under
the floor. These objects can block air circulation and cause loss of air
pressure, thus reducing system efficiency and causing hot spots in your
room.
APC should be notified before installation if the unit is incorrect for the
application.
Unit location The location of the unit is important for efficient and balanced
environmental control in your room. The air conditioner should be
located as close as possible to the largest heat load. In rooms having a
high aspect ratio, mount the unit along the longest wall to ensure even
air distribution. If improperly installed, erratic control or mechanical
failure can and will result.
Service access At least 36" (915 mm) of clear space must be left in front of the unit for
routine service (filters, humidifier).
