6.5 Maintenance Procedures
6.5.1 Removal and Installation of Access Panels
Removal
Remove the door and side panels in the humidifier as follows. Refer to Figure 10 on page 55 .
1. Turn the captive screw at the bottom of the door panel (control cabinet/plumbing cabinet) counter-
clockwise with a screwdriver.
2. Lift up the door panel slightly so that the top tabs clear the notches in the cabinet, then carefully
swing the bottom of the panel up, as shown, and remove the panel.
3. To remove the left/right side panel, remove the screws and slide the panel towards the front of the
unit, so the tabs in the side of the panel clear the notches in the fixed rear panel.
Note: The Nortec GS 50/100 does not have a removable left side panel. To remove the right side
panel, slide the panel towards the front of the humidifier until the tabs at the top rear and bottom
rear of the panel clear the notches in the cabinet, then remove the panel.
Installation
Install the door and side panels in the humidifier as follows. Refer to Figure 10 on page 55 .
1. Align and slide the side panel (left/right) towards the rear of the unit, so the tabs in the side of the
panel engage with the notches in the fixed rear panel. Install the screws and fasten the panel securely.
Note: To install the right side panel in the Nortec GS 50/100, align the tabs at the top rear and bot -
tom rear of the panel with the notches in the cabinet, then slide the panel towards the rear of the
unit until it is seated properly.
2. Position the door panel (control cabinet/plumbing cabinet) so that the two tabs in the top rear of the
panel align with the notches in the cabinet.
3. Lower the door panel to seat the tabs in the notches, while ensuring that the tabs in the (left/right)
side panel engage with the notches in the side of the door panel. Refer to the detail in the figure.
4. Make sure that the door panel fits flush on the front and the side. Turn the captive screw in the door
panel clockwise to secure the door panel. Check that it is fastened securely.
