When making process air connections to your dryer, ensure that you take into consideration and make arrangements for the following:
;Use
;Keep the delivery (to the drying hopper) hose as short as possible to minimize heat loss. Insulated hose is recommended and available for maximum energy savings.
;Do not use insulated hose on the return (from the drying hopper)
;Do not shorten the return hose. The return air to the blower must be 150°F or below.
;Make sure the hoses are not kinked.
;Drying hopper air inlet and outlet locations vary, but always connect the hoses so the dry process air from the dryer enters the bottom of the drying hopper and flows out the top to return to the dryer inlet.
