CAUTION
Investigate and determine the location of the AC coil prior to drilling holes in
duct for mounting unit. Use care to avoid damage to the coil and any wiring
or other components while installing the Haven Plus unit.
WARNING
To prevent water damage or electric shock, do NOT mount unit under
a humidifier.
1. Determine the air flow direction.
Now that you have located your air handler and where the HVAC
system is in your home, it is time to choose an install location.
Choosing the best location is dependent on what layout the
HVAC system has; Down Flow, Up Flow, or Horizontal Flow.
(Reference Figure B to see which layout matches your HVAC.)
2. Choose a suitable location for the unit.
Possible locations are downstream from the ‘A’ coil (Air
Conditioning Coil) in the supply plenum OR in the return plenum;
preferably downstream from the air filter.
For optimum “cleaning” effect on the ‘A’ coil, mount the unit in the
supply plenum as close as possible to the ‘A’ coil.
(Reference Figure B to pick the best install location for your
system’s air flow direction.)
NOTE:
SEAL the joints and seams of the plenum near the mounting location
to reduce any direct viewing of UV light.
