Installation Instructions and User Manual
Page | - 63 -
Stage 2 - Shut Down the Electrical Supply
CAUTION: Risk of electric shock. The electric supply of the humidifier must be
shut down. Disconnect the power at the external breaker before commencing
servicing.
Once the evaporation chamber is sufficiently cool, remove the power supply to the humidifier at the
circuit breaker.
Stage 3 - Remove the Evaporation Chamber
The evaporation chamber may still contain some hot water. Ensure that the bottom of
the evaporation chamber is cool enough to handle before removing it.
1. Turn off the gas and water supply valves located outside the humidifier.
2. With the front access door removed, disconnect the water inlet attached to the front of the
evaporation chamber, by removing the safety pin and manually disconnecting the hose shank
coupling. Connect and secure the water plug to the inlet in order to prevent water from leaking
out from the evaporation chamber.
3. Remove the safety pin and disengage the latch, in order to disconnect the band clamp
located around the evaporation chamber. Lift the band clamp up and secure it to the top
flange by closing the latch.
4. Lower the evaporation chamber using the lifting mechanism. Ensure that the lifting
mechanism is in contact and is supporting the chamber before lowering it.
Stage 4 - Clean the Evaporation Chamber
1. Remove the residue that has accumulated inside the chamber and poor out any remaining
water that is on the bottom of the container.
2. To clean out the remaining scale from the container, use a stiff brush (synthetic filament only)
and some vinegar or any weak acid suitable for cleaning stainless steel.
WARNING: The use of a wire brush or any non-recommended acid will void the
warranty.
3. Do not scrape off the walls of the chamber.
4. Ensure that the water inlet aperture is not blocked.
5. Rinse out the evaporation chamber with water.
Stage 5 - Clean the Other Components
1. Ensure that the evaporation chamber gasket is in good shape and is positioned properly.
Replace the gasket if it is worn or damaged.
2. Clean all the components of the evaporation chamber cover, including the heat exchanger
and combustion chamber. Use the same procedure as in Stage 4 to clean these components.
Stage 6 - Reinstall the Evaporation Chamber
1. Replace the evaporation chamber inside the humidifier and position it properly on the lifting
mechanism. Lift the chamber back up using the lifting mechanism. Ensure that the gasket is
well positioned in the cover groove.
2. Ease the evaporation chamber band clamp back into place and close the latch to lock the
band clamp on the evaporation chamber. Reattach the safety pin to the band clamp.
3. Disconnect the water plug and reconnect the water inlet to the evaporation chamber.
4. Turn on the gas and water supply valves located outside the humidifier.
5. Turn the power back on using the circuit breaker.
