7InRow RC Installation
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.
