Operator Interface Controls The operator interface in the Condair GS humidifier is located on the front of the unit – refer to Figure It consists of a touchscreen display with a LED status indicator, and an On/Off switch. Refer to Table 2 for a description of each of these elements.
The humidifier is stopped because a condition with a "Fault" status is active. Disabled The Condair GS humidifier is disabled by the BMS (building management system). Safety Loop One or more contacts in the external security loop is open, so the humidifier has stopped producing steam.
A condition with a "Warning" status is active. Typically, these conditions are of a temporary nature, or conditions that cannot cause damage to the system. Depending on the condition, the Condair GS humidifier may be stopped or remains operable (unless the warning relates to a control signal). If the cause of the condition clears on its own accord, the warning message is automatically reset.

Software Configuration The Condair GS humidifier is shipped fully configured from the factory to suit your site-specific require- ments, but this can be modified as needed. This section provides the necessary instructions to recon- figure the control software.
Configuring for Multi-Unit Operation Set up the control software for multi-unit operation as described below. A maximum of four humidifiers can be set up in a "Main-Extension" configuration using Condair's Linkup system to satisfy large hu- midification needs. IMPORTANT! This procedure should only be used to control multiple humidifiers that are using the same control signal inputs from the same conditioned environment.
5.2.1 Filling the System Fill the Condair GS humidifier as follows. The control software also performs the float test to ensure that the fill system, the water level controls and the drain pump(s) are functioning properly. 1. Close the manual gas shutoff valve in the supply line.
The blower(s) then performs a post-purge of the combustion chamber(s), and then shuts off. If there is no humidity demand, the humidifier goes into standby mode to await the next humidity demand signal. Operation xxxxxxx_A_EN_1905_Condair-GS_OM Condair GS...
5.2.4 Remote Monitoring The Condair GS humidifier can be monitored remotely through the remote fault board wired to a remote monitoring system. Table 7 describes the function of each relay when triggered. Table 7: Remote Relay Function Remote Relay Description...
During periods of inactivity, such as off-season or periods of low demand, drain the water from the tank. To drain the tank in the Condair GS humidifier, manually initiate draining as follows. Refer to . 1. Select the <Drain> button on the Home screen. If more than one humidifier is connected in a Linkup chain, select the appropriate tank, then press the check mark.
5.2.9 Restarting After Shutdown Restart the Condair GS humidifier as follows after it has been shut down for maintenance or at the start of the season: 1. Examine the humidifier and other system components for damage. Do not use the applicance if any part of the humidifier has been under water.
The exhaust vent connected to the Condair GS humidifier does not require cleaning, but needs to be inspected regularly for leaks, blockages, sagging and proper condensate removal.
Mandatory Maintenance Schedule Table 8 lists the mandatory maintenance schedule for the Condair GS humidifier. Table 8: Mandatory Maintenance Schedule 30 Days End of After Mid- Task Season Maintenance Initial season (2000 hrs) Start-up Inspect drainage. Perform a visual check of the drainage system, including the air gap funnel and drainage into the building drain.
Table 10) are not covered by warranty. The Condair GS humidifier periodically drains water from the tank to reduce the concentration of dis- solved minerals that accumulate during long-term operation. This is achieved in two ways – through a partial blowdown and a full tank blowdown (FTBD).
12, and make a note of the recommended minimum blowdown rate for the chloride level in the feed water. c. Set the Blowdown Rate on the Condair GS humidifier to the higher of the two noted values. 3. Set the FTBD interval as follows: a.
15-25 25-40 40-50 > 50 Not recommended for the humidifier without treatment of the water. Contact your local Condair representative. Maintenance Procedures 6.5.1 Removal and Installation of Access Panels Removal 1. Turn the captive screw at the bottom of the door panel (control cabinet/plumbing cabinet) counter- clockwise with a screwdriver.
3. Disconnect the fill hose from the drain fitting. 4. Remove and discard the tank gasket (Condair does NOT recommend reusing the tank gasket). 5. Use a soft-bristled or plastic brush or scraper (not wire brush, not metal) to remove all scale build-up on the inside surfaces of the tank, the outside of the primary heat-exchanger coils, and inside of the drain fitting.
6. Disconnect the condensate trap from the secondary heat-exchanger and flush out any scale build-up. 7. Reconnect the condensate trap, and prime the trap with water. 8. Re-start the humidifier – refer to "Restarting After Shutdown" on page 45 and check for leaks. Maintenance xxxxxxx_A_EN_1905_Condair-GS_OM Condair GS...
Rinse with clean tap water. 5. Visually check each float for cracks or other damage. Place the two floats in a container filled with clean water, and check that they both have equal buoyancy. If necessary, replace the floats. Condair GS Maintenance xxxxxxx_A_EN_1905_Condair-GS_OM...
6. Use a rubber mallet to knock out any scale build-up in the fill and drain hoses. Rinse the hoses thoroughly with hot tap water before installing the hoses. Secure the hoses with clamps. 7. Re-start the humidifier – refer to "Restarting After Shutdown" on page 45. Check for leaks. Maintenance xxxxxxx_A_EN_1905_Condair-GS_OM Condair GS...
Drain pump adapter 6.5.6 Cleaning the Burner Assembly The burner(s) in the Condair GS humidifier does not require maintenance. However, if the burner(s) is not operating properly, clean the burner(s) and spark-igniter as described below. Refer to Figure 1. Shut down the humidifier. Remove the plumbing cabinet door panel and make sure that the tank has been emptied.
Page 56
Check the electrode gap is 3 ± 1.5 mm (1/8 ± 1/16 in). DO NOT adjust the gap – replace the spark- igniter, if necessary. 8. Assemble the burner assembly in reverse order. Always use a new burner gasket. Maintenance xxxxxxx_A_EN_1905_Condair-GS_OM Condair GS...
2. Replace the fuse with a 10 A slow-acting fuse. 3. Close the front panel, and install the door panel, making sure that it is fastened securely. 4.
