1.0 INSTALLATION
WARNING: There is no intent on the part of Data Aire, Inc. to defi ne local codes and
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 tem-
perature and humidity. However, the room must be built with a proper vapor barrier. A fi lm of poly-
ethylene is often used on walls and ceilings. Floors must be painted with 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 conditioned (CRAC) unit setpoints to main-
tain the room’s design conditions.
1.2 Inspection
This equipment has been factory run-tested and has gone through a comprehensive inspection pri-
or 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 panel, disconnect switch handle and spare belts are packed
inside the unit. Refer to the yellow shipping tag located on the electrical section panel.
WARNING: Freight damage claims are the responsibility of the purchaser. Action to
recover losses should be fi led immediately. Please notify Data Aire 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 de-
termine the strength of the supporting structural members.
Appropriate service access above the ceiling is required around all service and electrical access
panels. There must unobstructed clearance below the unit allowing ladder access to enable routine
maintenance and service.
