Figure 1. Rigging Instructions. Vertical airflow type units should be located no closer than the width of the unit from a wall or other obstruction. It two or more units are to be positioned in the same area, a similar distance should be maintained between adjacent units. Sufficient free area should be left around and below unit to avoid air restriction to coil.

Table 4. Percentage of Ethylene Glycol to be Added by Volume. Percent % 20% 30% 40% Minimum Outside Design Temperature °F Table 4 is intended to be used as a guide only. Proper precautions need to be taken to prevent freeze damage during low ambients. Consult glycol ven- dor recommendations for specific freeze protection for your location.
Page 9: Start-Up
Start-up Prestart: Check for correct dry cooler fan rotation. This can be done by quickly jogging the fan contactor. Be sure that the fans run freely. The same check is recommended for pumps. Filling and Purging the System The system should be pressure tested before adding glycol. The system can be tested with air or water, however if the ambient temperature is at or below freezing the use of air is recommended.
Page 10: Walls Or Obstructions
Walls or Obstructions The unit should be located so that air may circulate freely and not be recirculated. For proper air flow and access all sides of the unit should be a minimum of “W” away from any wall or obstruction. It is preferred that this distance be increased whenever possible.
