Paperwork
Each Data Aire CRAC unit ships with a start-up sheet that should be completed during installation.
Also included in the paperwork is a warranty/information packet that provides important wiring
diagrams, specific component literature, warranty registration cards and other valuable
paperwork, including a copy of this Installation, Operation, and Maintenance manual.
A yellow tag is attached to the outside decorative door to indicate articles that may have been
packaged and shipped loose within the unit cabinet. Typically this would be jackstands,
condensate pumps and other loose components that are not factory mounted.
WARNING:
It is the responsibility of the installing contractor to return the
start- up sheet and warranty registration card to Data Aire for proper
activation of the unit warranty. Failure to do so may cause delays and
some cases void the warranty

Storage
Short-term storage is considered 60 days or less from shipment date. Long-term storage is
considered any period beyond 60 days from date of shipment. It is mandatory that a detailed
record be maintained during this long-term period, such as, but not limited to: proper sealing of
the cabinet, rotation of the blowers and bearings, and protection of all motors from moisture.
Check the fan rotation monthly, the fan and motor should be rotated several times to replenish
the bearing surfaces with fresh grease as needed and to prevent flat spots of the fan shaft. The
fan impeller should be left at approximately 180° from that of the previous month to prevent the
belts from taking a set position.
It will be the responsibility of the customer to submit a monthly log sheet showing the condition
of the unit and noting any discrepancies. A copy of the log sheet should be sent to Data Aire.
Failure to perform the long-term storage requirements may void the warranty.
1.5.1. Suggested Reference Storage Room Conditions
•
Dry bulb temperature range: 65°F to 85°F.
•
Effects of high temperatures may dry out components or may damage electrical
components.
•
Effects of low temperatures may cause freezing damage to coil, compressor, system
components, electrical components, etc. Freezing temperatures must be avoided.
•
Humidity range: 25 to 50% RH.
•
High humidity may cause damage to insulation and electrical components. Storage in
moist air, above 50%, should be avoided. High humidity may cause rust on metal
components such as sheave, pulley, blower housing, cabinet parts, supports, etc.
•
Low Humidity may cause brittle conditions to components within the unit. At low humidity,
problems of brittleness or electrical static might arise for the equipment.
•
Level with floor.
•
Units with compressor maximum tilt angle is 30° (compressor not running) but
recommend the unit be set level for 24 hours prior to final installation.
