1.0 INSTALLATION

There is no intent on the part of Data Aire, Inc. to defi ne local codes or statutes which
may supersede common trade practices. The manufacturer assumes no responsibility
for their interpretation. Consult local building codes and the National Electrical Code
for special installation requirements.
1.1

Room Considerations

Precision air conditioning equipment is designed to control spaces within close tolerances of
temperature and humidity. However, the room must be built with a proper vapor barrier. A fi lm of
polyethylene is often used on walls and ceilings. Walls and fl oors must also be painted with a vapor-
seal paint. All doors to the controlled space should be equipped with weather seals to prevent the
infi ltration of non-neutral conditioned air from external spaces. Failure to provide a vapor barrier can
compromise the ability to control space conditions.
Introduction of outside air into the space should be minimized. Outside air in excess of 5% of the
total circulated air volume can have a signifi cant effect on the overall space conditions and result
in poor space control. All outside air that is introduced should be conditioned to the humidity and
temperature parameters of the computer room air conditioner (CRAC) unit set points to maintain
proper room conditions and to prevent the CRAC units from running excessively to maintain the
room's conditions.
1.2

Inspection

This Data Aire unit has been factory run-tested and has gone through a comprehensive inspection
prior to its packaging and shipment to ensure that it arrives in excellent condition. However, shipping
damage can occur and a visual inspection of the outer crating immediately upon delivery should be
performed.
Note any external damage or other transportation damage on the freight carrier's forms. Inspect the
unit itself for internal damage. A claim should be fi led with the shipping company if the equipment
is damaged or incomplete.
Loose items such as remote control panels, disconnect switch handles, spare belts and spare fi lters
are packed inside the unit. Refer to the manila shipping tag located on the unit panel for details.
Freight damage claims are the responsibility of the purchaser. Action to recover
losses should be fi led immediately. Please notify factory personnel of any claims.
1.3

Locating the Unit

The unit is intended for above the ceiling installation and is typically suspended from structural
members in the building above the ceiling. Add at least a 50% safety factor to the weight of the unit
to determine the necessary strength of the supporting structural members or follow local code.
Appropriate service access above the ceiling is required around all service and electrical access
panels. There must be unobstructed clearance below the unit allowing ladder access to enable
routine maintenance and service. Consult local building codes and National Electric Code for special
installation requirements.
