2.6.3 Outdoor Condensers

Chapter 2: Installation

2.6.3 Outdoor Condensers

Referring to the IOM manual provided with the condenser, install the remote condenser in a secure location where it cannot be tampered with, and the service disconnect switch cannot be inadvertently turned off. Locate the remote condenser where the fan is not likely to draw dirt and debris into the coil fins. The clearance around the condenser should be at least 1x the unit's width to ensure adequate airflow to the coil. Secure the condenser to prevent the system from moving during operation. We recommend installing the remote condenser with vibration mounts to reduce vibration transmitted to the mounting surface.

2.7Water–Water-/Glycol-Cooled DX (CRDX-W-FS-12W, CRDX-W-FS-24W, CRDX-G-FS-12W, and CRDX-G-FS-24W models)

The system uses an external source of fluid to provide coolant to the condenser inside the A/C unit. No refrigeration connections are required for self-contained water- or glycol-cooled systems (see Figure 2-7).
