Page 7: Unpacking/Setting Up
Unpacking/Setting Up _________________ Remove protective shipping material (i.e., plastic wrap, and/ or optional shipping box) from dryer. Important Dryer must be transported and handled in an upright position at all times. The dryer can be moved to its final location while still attached to the skid or with the skid removed. -
Page 8: Fresh Air Supply Requirements
Important Even though a minimum of only 12-inches (30.48 cm) is required, 18-inches (45.72 cm) or more is suggested. The additional clearance is advantageous for ease of installation and service. Fresh Air Supply Requirements _______ When the dryer is operating, it draws in room air, heats it, passes this air through the basket (tumbler), and exhausts it out of the building. - Page 9 suggested that the use of 90° turns be avoided; use 30° and/or 45° angles instead. The radius of the elbows should preferably be 1-1/2 times the diameter of the duct. Including basket (tumbler)/dryer elbow connections or elbows used for outside protection from the weather, no more than one (1) elbow should be used in the exhaust duct run.
