MOUNTING
STEP ONE:
Select the Mounting Location
Choose a location that has access to a water supply
pipe. Cold or hot water can be used.
Select a vertical or horizontal surface on the HVAC
duct work, with adequate space clearances,
where the humidifier can be mounted. For bypass
installation, access to both the return and supply are
required. Both humidifier models can be mounted to
either the supply or the return.
Location must also have access to 120 VAC power.
For the HE300 Fan humidifier, the power cord is 6 feet
long.
Ensure the location is near a drain. Consult local
plumbing codes for proper drainage. If no main
floor drain is available,
see “Appendix B: Advanced
Draining.”
STEP TWO:
Install Mounting Template to the Duct
Position the template on the duct.
Make sure the template is level and in the desired
•
position on the duct.
Ensure proper clearances from the air-conditioning
coil inside the duct.
NOTE: The HE300 Fan model extends into the duct
1-3/4 inch. Bypass models extend into the duct 1/2
inch. Ensure clearance inside the duct.
For best performance, maintain at least 24 inches
•
downstream of open air space inside the duct.
Use a marker to trace the template outline onto the
duct, then remove the template.
Cut the sheet metal, following the template outline.
