it may be secured by bolting the base to the floor but is not required. This standard dryer is designed
for indoor installation. Contact distributor if installing unit outdoors.
Installations at altitudes above 4000 feet (1219 meters) will experience a loss of capacity and may require
field adjustments of pressure settings. The unit has been factory adjusted to operate up to 4000 feet
(1219 meters), and if installation is above this altitude, contact your local distributor for correct refrigerant
settings.
