Selecting a location for the OASys

The following information will help in selecting a location for the OASys:

•  The OASys may be mounted on an outside pad, a roof or bracketed to a wall.  The OASys can 

be placed in a garage with adequate drainage in case of overflow or leaks.  Indoor installation 

such as in an attic or utility closet is possible but not recommended.  If the unit is not properly 

installed leaking can occur which could seriously damage the interior of a home.  A drain pan 

should always be used in such an installation in case of condensation or other leaks.  Interior 

installation may nullify certain parts of the warranty and or service agreements.  

•  The OASys requires a dedicated 115V circuit, cold water supply, and a location to discharge drain 

water in accordance with local codes.

•  A supply air connection to the house, an outside air intake, and a “secondary” air outlet must be 

provided  

(see Fig. 1).  Secondary air should be discharged to the outside, and may be discharged into an 

attic or space  

vented to the outside.

•  Do not install the unit such that the air intake is 10 feet or less from an appliance vent outlet,
