Figure 2: One Condenser Head Pressure Module Dimensions

Mounting

The One Condenser Head Pressure Module is housed in a plastic en-
closure. It is designed to be mounted by using the 3 mounting holes in
the enclosure base. It is important to mount the module in a location
that is free from extreme high or low temperatures, moisture, dust, and
dirt. Be careful not to damage the electronic components when mount-
ing the module.

See Figure 2 for Module dimensions (in inches).
