4. SYSTEM INSTALLATION
4.1 SLIMZONE PREMIER CONTROL MODULE (SZP)
4.1.1 REMOVAL AND INSTALLATION OF THE DOOR
Installer should touch a grounded metal object before handling the control panel to avoid
potential loss of programming due to static discharge.
NOTE:
The door is hinged on the left side.
Open the door by gently pulling on the bottom right corner, applying finger pressure only. The
door may be removed once opened by applying a slight backward pressure. Replace the door
by hooking around the tabs on the left side of the backplate and snapping back into place.
4.1.2 INSTALLATION OF THE BACKPLATE
The control module can be mounted on any interior surface. Use the mounting holes on the
backplate of the main unit and the two (2) mounting holes on the expander modules (if so
equipped) to secure using the supplied #8 screws (Figure 4.1). Mount the control module in a
location that provides easy access for service. Do not mount the control module on any part
of the HVAC equipment or where moisture may be present. There are several round holes and
knock-outs for through-the-wall or surface wiring.
CAUTION: Use proper care when removing upper or lower end cap knock-outs. Apply a
sharp rap with the butt end of a screwdriver to remove. Do not use sharp instruments to
remove the knock-outs as internal damage may occur.
