Room Preparation

During the design of the data center, consider ease of entry for the equipment, floor loading factors, and accessibility to piping and wiring.

Seal the room with a vapor barrier to minimize moisture infiltration. (Polyethylene film is recommended for ceiling and wall applications.) Apply rubber- or plastic-based paints to concrete walls and floors.

Insulate the room to minimize the influence of exterior heat loads. Use the minimum required amount of fresh air for make up to comply with local and national codes and regulations. Fresh air imposes extreme load variation on the cooling equipment from summer to winter and causes increased operating costs.

The equipment is designed as a sensible cooling air conditioning unit for in-row use in data centers. The equipment does not have humidification or dehumidification control. Room humidity must be within acceptable operating conditions before starting equipment. If operated in spaces where the humidity is in the unacceptable operating conditions section of the Operating Guidelines chart (see the InRow RC Operation and Maintenance manual) the equipment condenses excess water vapor from the air. This will exceed the pumping capacity of the condensate pump, causing the equipment to send an alarm and shut down to avoid overflowing the condensate pan. The condensate pump runs until the fluid level in the pan is reduced, and the alarm is automatically reset. The equipment self-regulates in this manner until normal operating conditions are present.

Note: The InRow RC is not intended to be used in an occupied office environment, due to potentially high noise levels during peak loads. Install the InRow RC in a computer room where people are normally present only for maintenance.

Incoming power supply requirements

See the electrical rating label on the equipment to determine the maximum possible current draw of the equipment. Provide either a single outlet circuit or a Power Distribution Unit (PDU) with sufficient capacity to handle all loads. Do not plug two InRow RC units into the same branch circuit or PDU.

The equipment must be grounded. Electrical service must conform to national and local electrical codes and regulations.
