Never
allow the return grille of a DRY-O-TRON® to be located near
or above a spa or hot tub.
The temperature and agitation of spas increases the rate of production of
corrosive chloramine gases. Chloramines are corrosive to most metals
found in buildings, electrical systems, and HVAC equipment.
Also, over time oxidized human skin oils will irrevocably foul the return
duct and damage the DRY-O-TRON
®
. Oxidized oils cannot be removed by
washing.

Locate the return-air grille(s) as far away from a spa or hot tub
as possible. At minimum install the return grille so that it will be
more than twice the width of a spa or 20 ft. (6 m.) (whichever is
greater) horizontally away from the edge of the spa or hot tub.
Never install a return grille above a spa or hot tub, or inside the
imaginary cylinder marked “Exclusion Zone” at right.
IMPORTANT!
The better solution is to locate the return grille well away from
the spa and take the room-exhaust air from above the spa. In this
case, the example exhaust system would be by others.
