2 SITE PREPARATION
2.1 Site Considerations
• Condensers should be installed in a location offering maximum security and access for
maintenance.
• Avoid ground-level sites with public access and areas prone to heavy snow or ice
accumulations.
• To ensure adequate air supply, Vertiv™ recommends that condensers be installed in an area
with clean air, away from loose dirt and foreign matter that might clog the coil. In addition,
condensers should be located no closer than 3 feet (1m) from a wall, obstruction or adjacent
unit.
• For roof installation, mount the condenser on suitable curbs or other supports in accordance
with local codes.
• Condensers must not be installed in a pit.
• Condensers must be installed on a level surface to ensure proper refrigerant flow.
• Use caution when installing condensers below the indoor unit. Condensers must not be
installed more than 15ft. (4.6m) below the indoor unit. Condensers with Liebert Lee-Temp™
receivers must be installed at or above the level of the indoor units to maintain proper
subcooling.
• Liebert Lee-Temp receiver tanks should be mounted on the condenser legs for proper
operation. Contact Vertiv™ Application Engineering Department for assistance with
applications requiring remote mounting of receivers.
• Condensers must be installed in vertical airflow orientation to maintain the electrical box’s
NEMA 3R rating.
