- Page 2 How The SD 2000 Works The SD 2000 humidifier is what is called an “electrode” humidifier. This means that instead of heating elements, metal electrodes are immersed in water contained in a plastic cylinder. When steam is required for humidification, electric current flows through the water between the electrodes.

Page 8: Connect Plumbing
The water feed connection is a 3/4” MPS male connection on the bottom of the humidifier (2 on SD360 & 384 models, 3 on SD3B3). Carel supplies a plastic adapter that screws onto the fill fitting and gives a 1/4” OD compression fitting for plastic or copper tubing. -
Page 9: Connect Power Wiring
Each SD humidifier is internally wired for the maximum amperage that it can see on any voltage. Electrical wiring sizes must match all national and local electrical codes. Generally, the following maximum wire sizes can be... -
Page 10: Connect Control Wiring
5.2. Controls Wiring The SD humidifier controllers are preprogrammed from the factory to operate either as On/Off (CDC), Proportional from a control signal (CDP), or Proportional from a sensor input (CDH, CDD). Wiring the CDC On/Off Controller:... - Page 11 24 Vac/dc at 1 Amp. There is also a CDT controller that reads a temperature sensor input and controls the SD humidifier for use in a Turkish bath. It is wired the same was as the CDH controller, but with a temperature sensor instead.

Page 12: Install Steam Distributor Pipes
Installation & Maintenance Manual 6. Install Steam Distributor Pipes If your SD 2000 humidifier was supplied with duct steam distributor pipes, they must be mounted completely level in the duct with the steam outlet holes facing up as shown to the right. -
Page 13: Install Steam Hoses
Nothing must impede the free flow of either steam to the distributor pipes or condensate back to the SD unit or the drain. If Copper tubing is used, use two 45° angles or sweeping elbows rather than sharp 90° elbows. -

Installation & Maintenance Manual 8. Install Room Distribution Unit Models SD101-313: If your SD 2000 humidifier was supplied with a direct mount RDU (Room Distribution Unit), it will have been shipped in place, ready to go. Simply mount the humidifier unit on the wall per the instructions in Section 2 and proceed to the unit wiring instructions. - Page 15 Carel USA Models SD323-3B3: The VRDXL used on the SD323-3B3 units is only available as a remote unit (wall mounting bracket supplied), although it can be mounted on the wall directly over the humidifier unit if desired. (2 VRDXL units are required for models SD360-384 and 3 are required for the SD3B3).

Fittings are tight. NOTE: Inlet water pressure must be between 15 and 150 psi. If higher than 150 psi, install regulator. -
Page 17: Operating The Sd 2000 Humidifier Controller
10. Operating The SD 2000 Humidifier Controller The SD 2000 controllers all have the same general display and keypad as shown below. Initially, the CDC and CDP controllers default to display of the amperage, while the CDH and CDD controllers default to display of the relative humidity. - Page 18 Installation & Maintenance Manual CDP 303: control is modulating. The controller has an input for an external modulating signal from a proportional humidity controller or DDC system. The input signal can be selected by the dip-switches located on the back of the controller.

Page 21: Maintaining Your Sd 2000 Humidifier
11. Maintaining Your SD 2000 Humidifier Although your SD 2000 humidifier is designed to take care of its normal operation, and even to provide you with diagnostic capability, good operation always means good maintenance. Periodic cleaning or replacement of the steam generating cylinder, and fill and drain valves is required as indicated by the controller with an E08 alarm. - Page 22 Installation & Maintenance Manual To clean the fill and drain valves: After shutdown and removal of the steam cylinder, shut off the water supply to the humidifier, disconnect the water supply and remove the fill valve from the humidifier. Remove the inlet strainer by reaching up into the fill valve inlet with a pair of needle nose pliers and pulling out the strainer by its tab.

Whenever there is an alarm or pre-alarm condition, a cursor appears on the left of the LCD display pointing to ALARM. - Page 25 Carel USA E06 CURRENT TOO HIGH: When amperage exceeds the second safety threshold. Causes: 1. Mineral bridge between electrodes. 2. Leakage of fill valve. 3. Blocked drain valve. 4. Back pressure from improper steam hose installation or duct. 5. TDO setting between 0 & 120.
- Page 26 Installation & Maintenance Manual E11 HIGH HUMIDITY: (In CDD models only) Causes: 1. Humidity has exceeded the high limit alarm setpoint. Remedies: 1. Check control circuit. 2. Check calibration of humidity sensor. 3. Raise hi-limit setpoint. E12 LOW HUMIDITY: (In CDD & CDH models only) Causes: 1.
- Page 27 Carel USA WATER IN THE CYLINDER TURNS BLACK: Causes: 1. This is usually an indication that the minerals in the cylinder have overconcentrated and the pH of the water has dropped causing a deterioration of the electrodes. Left unchecked, this will lead to a very short cylinder life.
- Page 28 Installation & Maintenance Manual HUMIDIFIER CONTINUOUSLY FILLS AND DRAINS WITHOUT PRODUCING STEAM: Causes: 1. Mineral has bridged between the electrodes. 2. There is back pressure from the steam hoses or duct. 3. The flow regulator in the fill valve is broken or out of place. 4.
- Page 29 Carel USA POWER CONTACTOR CHATTERS: Causes: 1. Installation dirt has gotten into the contactor and is interfering with its free movement. 2. Secondary voltage is too low. 3. Controller triacs are weak or damaged. Remedies: 1. Clean out the contactor or replace it.
