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 2 m above the floor.

Allocate a minimum clearance of 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 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.

Connecting Condensate Hose to Humidifier

If connecting a condensate hose to the humidifier using the top knockout hole, remove the plug from

the open silicone pipe near the water fill valve. Then, insert a ½” fitting (not supplied) inside of the

silicone pipe and connect the end of the ½” condensate hose (not supplied) on the fitting. Use a hose

clamp (not supplied) on each end of the hose to secure the connection.

Electrical Installation

CAUTION: Risk of electric shock. Disconnect the SDU from the electric supply

before proceeding with the connection.

The wiring to the SDU must be done by a qualified electrician and must conform to the

procedure, regulation and local codes.

Use copper conductors only.

An external over current protection must be installed on the supply, adjacent to the SDU.

It is also recommended to install a circuit breaker.

To provide strain relief to the supply cable, install a knock-out (not supplied) at the bottom

of the SDU.

Ensure that the size of the wire conductors is appropriate for the current supplied.

Ensure that each terminal connection is properly secured.

Ensure that the ground conductor is equipped with a ring terminal and is connected

directly to the electrical panel.
