Return Grille Location
The return grille of a DRY-O-TRON® must be located far from 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.
INSTALLATION
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 and the spa well
away from each other and exhaust the air above the spa. In this
case, the spa-exhaust system should be by others.
