1.0 INSTALLATION
There is no intent on the part of Data Aire, Inc. to defi ne local codes or statutes which
may supercede 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 or 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 entering the space. Failure to provide a vapor barrier
can compromise the ability to control space conditions.
Introduction of outside air into the controlled 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 yellow shipping tag located on the unit door 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 a 50% safety factor to the weight of the unit to
determine the strength of the supporting structural members.
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.
