8.4.2 Cleaning, Removing, and Installing the Water Reservoir
Cleaning and Disinfecting Considerations: Water Reservoir
The water reservoir houses very delicate piezoelectric transducers that may break during
cleaning/removal/installation. To avoid damaging the transducers, avoid removing the water reservoir from the
unit unless it is necessary. This may impact cleaning/disinfecting procedures, so care must be taken:
l
Gently spray the reservoir with clean water to rinse away residue, or allow the reservoir to fill and drain
several times to rinse it out.
l
Clean with a soft cloth.
l
After cleaning with soap, instead of scrubbing off scale, soak the water reservoir in citric acid (pH 2) for
15-20 min. Approximately 3 L (0.8 gal) is necessary to fill the reservoir without it overflowing through the
fan opening.
l
To disinfect, spray the water reservoir (drained) with hydrogen peroxide (0.1% solution) and allow to air
dry. The unit may be wiped with disinfectant, however, care must be taken that the sensitive piezoelectric
transducers are not damaged.
If the reservoir should be removed from the humidifier, refer to the steps in "Removal" below .
Citric acid can be ordered from Condair (PN: 2589797).
The following instructions can only be performed while the water reservoir is removed from the unit. It is
suggested to also inspect and perform maintenance on the UV assembly and transducers before the water
reservoir is reinstalled into the humidifier.

Removal
Remove the water reservoir as follows. Refer to Figure 16 on the next page .
1.
Shut down the humidifier as described in "Shutting Down the Unit" on page 37 .
2.
Remove the door panels. Refer to "Removing and Installing the Door Panels" on the previous page .
3.
Remove the flexible tubes on top of the water reservoir.
4. Disconnect the two electrical connectors on the water reservoir. Refer to Figure 17 on the next page .
5.
Disconnect the earth connector from the earth tab. Refer to
Figure 17 on the next page
.
6.
Unscrew fastening bolt on the top of the water reservoir. Refer to
Figure 16 on the next page
.
7.
Lift the water reservoir out of the drain valve by wiggling the reservoir.
8.
Discard the O-ring in the drain valve. The O-ring must be replaced when reinstalling a reservoir.
Installation
Install the water reservoir as follows. Refer to Figure 17 on the next page .
1.
Lubricate a new O-ring with water – do NOT use grease, oil, or any other lubricant. For safety reasons,
always install a new O-ring in the drain valve.
2.
Make sure the new reservoir is of the same model as the one removed. This can be determined by the
size of the reservoir or the number of piezoelectric transducers.
3.
Position the water reservoir above the drain valve. Carefully slide the drain connection of the reservoir
into the drain valve.
4.
Insert and tighten the two fastening bolts on top of the reservoir to secure the reservoir in place. Refer to
Figure 16 on the next page .
