Drain line must be piped as shown in Figure 22-1. Provide a 152 mm drop prior to a 102 mm water seal to ensure condensate drainage from the SDU-E, and to keep steam from blowing out of the drain line. 3. After the water seal, run the drain line to an open drain with a 25 mm vertical air gap.
Installation % J T Q F S T J P O 4%6 * BOE 4%6 & SDU-E rise, spread, and throw Figure 23-1: SDU-E rise, spread, and throw As steam is discharged from the SDU-E, it quickly cools and turns to a visible fog that is lighter than air. As this fog is carried away from the SDU-E by the airstream, it tends to rise toward the ceiling. If this fog contacts solid surfaces (columns, beams, ceiling, pipes, etc.) before it disappears, it could collect and drip as water.

Operation 4UBSU VQ DIFDLMJTU If an item in the Start-up checklist below does not apply to your system, skip to the next item and continue the process. ☐ Read this manual and all other information that was provided with your humidifier. ☐ Verify that all field wiring is done according to the instructions in this manual and in the humidifier wiring diagram. ☐ Confirm that the input signal is consistent with the Vaporlogic4 controller's expected input signal.
Maintenance 5B Q T P G U F O F E X B U F S The best way to determine how often your humidifier needs maintenance is to remove the tank cover and inspect it for mineral deposits after three months of duty. Hours of operation and duty cycle will determine your maintenance schedule, as will water quality.
Maintenance 5B Q T P G U F O F E X B U F S Figure 36-1: Cover enclosure screw cap detail Cool down humidifier Before performing any maintenance, allow the tank to cool down. Fresh make-up water is used to speed up cooling. Do not close the manual water supply before cooling down the humidifier; otherwise the tank could stay hot for several hours.

Maintenance %* 30 XBUFS PQUJPO WARNING Hot surface and hot water hazard Do not touch the tank or drain piping until the unit has had sufficient time to cool, or serious injury can occur. Opening the drain valve when the tank is hot can discharge water with a temperature up to 212 °F (100 °C) into the plumbing system. This can cause damage to the plumbing system if the humidifier is not properly connected to a water tempering device such as a DRI-STEEM Drane-kooler™.
Maintenance %* 30 XBUFS PQUJPO 2. Loosen the four cover bolts and remove the cover assembly from the tank. 3. Inspect the tank interior for debris or pitting. 4. Inspect the valve inlet for debris. 5. Check the operation of the float valve and the condition of the float seat. 6. Check the low water switch to make sure the float slides freely on the stem. 7. Secure the chamber cover making sure the cover gasket is seated and the chamber is sealed. 8. Reinstall the evaporating chamber.
