WARNING

1. 120 Volts may cause serious injury from electrical shock. Leave

power disconnected until installation is complete.

2. The zone panel is designed for indoor use only. Do not expose any of the components to moisture.

CAUTION

1. Turn o the system power before removing or installing any

wires into the terminals of any component on the system. Wiring with a live circuit can lead to electrical shorts that can damage components.

2. Installation must be done in accordance with all applicable codes.

3. Installer should touch a grounded metal object before handling the zone panel. This will prevent any static discharge that may cause damage.

4. A zone panel may not control temperature properly unless the heating and cooling system is properly sized and balanced.

5. Insucient air ﬂow or excessive temperatures through the heating and cooling system could result in equipment damage. Refer to the manufacturer’s recommendations for minimum safe airﬂow and temperature requirements.

6. Do not mount the zone panel on any exterior wall or equipment supply ductwork.

7. Do not install the zone panel where temperatures exceed 158°F (70°C) or are below 32°F (0°C), non-condensing.

8. Improper system installation could cause water damage from frozen pipes. Check system operation after installation.
