NOTE: All lines are Type L ACR hard-drawn copper pipes.

NOTE: Shutoff valves shown nearest to the condenser are provided in receiver kit.

NOTE: Pitch all lines in the direction of refrigerant flow: 4 mm per m (1/2 in. per 10 ft).

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.

AMBIENT TEMPERATURE (°F)

Seal the room with a vapor barrier to minimize moisture infiltration. Polyethylene film is recommended for ceiling and wall applications. Apply rubberor 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.

WARNING

ELECTRICAL HAZARD

•Electrical service must conform to local and national electrical codes and regulations.

•The equipment must be grounded.

Failure to follow these instructions can result in death, serious injury, or equipment damage.
