Mechanical and Piping Installation
Positioning
The SDU must be installed in an environment where the air is relatively clean. This will prevent the blower
from getting clogged with dust.
The SDU must be mounted such that the SDU fan section is at
least 78” (2 m) above the floor.
Allocate a
minimum clearance of 18” (0.45 m) from the ceiling to avoid ceiling and wall condensation.
If additional ventilation is not present, ensure that the fan has a clearance
of at least 54” (1.35 m) from the
ceiling. Proper ventilation must be observed to avoid ceiling and wall condensation.
Remote Installation
To install the remote SDU, follow the guidelines and piping recommendations outlined below.
Mount the SDU to the wall on brackets (supplied). Do not drill mounting holes through the cabinet of the SDU.
Connect the steam hose to the bottom inlet of the SDU and to the humidifier steam outlet located on top of
the cabinet.
Secure the steam hose with the hose clamp (supplied).
Connect the condensate hose to the bottom of the SDU and to an open drain or to the humidifier using the
knockout hole located on the top of the cabinet.
Connect the electrical wires from the SDU to the top of the humidifier. Field wiring must conform to local
codes.
The fan of the SDU will operate for a period of five minutes after steam production has stopped to prevent
condensation.
Avoid any obstruction of the ventilation openings on top of the SDU.
