NOTE: Route piping through the top or bottom of the InRow RD cooling unit.
NOTE: Trap the vertical discharge line every 6 m (20 ft) to ensure proper oil return.
NOTE: The maximum piping run is 91 m (300 ft) equivalent length. Size the piping pursuant to accepted
refrigeration practice.
NOTE: Condenser can be placed up to 4.5 m (15 ft) below the indoor cooling unit for equivalent line lengths of
8 m (25 ft) or less.

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. In addition, the room temperature and humidity combination should conform
to the environmental operating envelope as defined in the following graphics.

RELATIVE HUMIDITY (% RH)
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. Reduce fresh air to the minimum required by
local and national codes and regulations. Fresh air imposes extreme load variation on the cooling equipment
from summer to winter and causes increased system operating costs.
Air distribution
The equipment distributes air in a back-to-front discharge pattern, removing hot air from a hot aisle and
discharging cooled air into a cold aisle.
NOTE: The equipment is designed for free air discharge or for use with the Rack Air Containment System or
EcoAisle Containment System. The equipment is not intended to be connected to a duct system.
