6.5.2 Cleaning the Tank
Clean the inside of the tank, the outside of the primary heat-exchanger coils and the drain fitting as follows.
WARNING!
Risk of severe burns from contact with hot surfaces, steam or hot water!
The tank may contain steam or hot water at up to 212
°
F (100
°
C). Contact with the hot sur -
faces, steam vapors or hot water can result in severe burns .
Prevention : Drain the tank and allow the unit to cool down to a safe temperature before cleaning
the tank. Never open the tank until it has been fully drained. Never use the manual drain valve until
the unit has cooled down. Use the manual drain valve to verify that the tank is empty before remov -
ing the tank cover.
CAUTION!
Risk of damage to the humidifier components!
Do not
use solvents, aromatized or halogenized hydrocarbons, or other harsh chemicals for clean -
ing. Disinfectants may only be used if they do not leave behind toxic residue. Rinse all parts thor -
oughly with clean tap water after cleaning.
Note:
It is not necessary to remove the tank from the unit in order to clean it.
1. Use the Clean Tank function in the control software to flush and drain the tank.
2. Shut down the humidifier as described in "Shutting Down" on page 48 .
3. Remove the door panels (refer to "Removal and Installation of Access Panels" on page 54) and all covers.
4. Disconnect the fill hose from the drain fitting.
5. Remove the door locks, four clamps, and the tank cover. Remove and discard the tank gasket.
6. Use a soft-bristled brush (not wire brush) or plastic (not metal) scraper to remove scale build-up from the
inside surfaces of the tank, outside of the primary heat-exchanger coils, the inside of the drain fitting, and
carefully from the surface of the temperature sensor. Vacuum out the tank.
7. Rinse the drain fitting and the inside of the tank thoroughly with clean tap water.
WARNING!
Risk of fire!
DO NOT clean the sacrificial anode with any chemicals
. The anode can react with acids to
create flammable hydrogen gas.
8. Inspect the sacrificial anode on the inside of the tank cover for excessive corrosion or scale build-up.
Use a soft-bristled brush (not wire brush) to remove scale build-up. Replace the anode, if necessary.
9. Install a new tank gasket (Condair does not recommend reusing the tank gasket), and secure the
tank cover to the tank as follows:
Note:
The order of installation/torquing of the bolts for the tank cover are shown in the hexagonal symbols in
Figure 12 on page 57
. Tighten bolts with your fingers and torque at the end of assembly.
CAUTION!
Risk of damage to the humidifier components or injury!
DO NOT over-torque the bolts. Ensure the proper order of torquing is followed. Failure to do so may
cause damage to the humidifer components or injury. Re-torque values are located Table A1 on page 89 .
a. Loosen jam nuts and M8x25 screws on all clamps. Remove top clamps by removing the M6x40
screw securing them in place.
b. Remove the door locks then side clamps, then remove the door and bottom clamp.Put bottom
clamp in place with tabs at ends of the bracket resting on the supports that extend from the tank.
