SAFETY INSTRUCTIONS
WARNING
1. 120 Volts may cause serious
injury from electrical shock.
Sudden operation may cause
serious injury from moving parts.
Leave power disconnected until
installation is complete.
2. Sharp edges may cause serious
injury from cuts. Use care when
making duct openings and
handling ductwork.
3. The Aprilaire Zoned Comfort
Control System is designed for
indoor use only. Do not expose
any component of the zone
control system to moisture. Do
not mount any Aprilaire Zone
Control equipment where it may
be accessible to children.
CAUTION
1. Turn off 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
Aprilaire control panel to avoid potential loss of internal computer
programs due to static discharge.
4. A Zoned Comfort Control system may not control temperature properly
unless the heating and cooling system is properly sized and balanced.
5. Insufficient 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. Excessive pressure across a bypass evaporative type humidifier may
cause high air velocity in the humidifier, resulting in water being blown
into the ductwork. Refer to Design Guide (form 5001) for humidifier
installation considerations.
7. Install an outdoor thermostat to prevent non-seasonal equipment starts
if using auto changeover thermostats.
8. Do not mount the control panel on any part of the heating/cooling
equipment or ductwork.
9. Do not install control panel where temperatures exceed 158°F (70°C)
or are below 32°F (0°C).
10. Improper system installation could cause water damage from frozen
pipes. Check system operation after installation.
Read this Installation Manual before beginning installation of the Aprilaire Zoned Comfort Control System.
