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 (NEC)

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 conditioner (CRAC) unit setpoints to maintain

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 a remote control panels, disconnect switch handles and spare belts are packed

inside the unit. Refer to the yellow shipping tag located on the electrical section panel.

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 Rigging

Move the unit in its upright position to the installation site. It is recommended that the unit be pro-

tected from damage to the decorative doors during any storage or moving. Removal of the decora-

tive doors is easily accomplished and may be done when moving the equipment.

The shipping skid should be left in place if the unit is being moved with a forklift. If the unit is being

lifted, use spreader bars to prevent damage to the doors and panels.

The unit has 3/4” holes in the shipping skid to which casters with 3/4” stems can be attached. This

allows easy movement down halls, into elevators and through doorways. If (height) clearance is a
