Read this Installation Manual before beginning installation of the Aprilaire Zoned Comfort Control System.
For questions call Research Products Corporation at (800) 334-6011.
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 Zoned Comfort Control equipment where it may be accessible to children.
CAUTION
1.Installation must be done in accordance with all applicable codes.
2.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.
3.A zoned comfort control system may not control temperature properly unless the heating and cooling system is properly sized and balanced.
4.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.
5.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 for humidifier installation instructions.
6.Install an outdoor thermostat to prevent non- seasonal equipment starts if using auto changeover thermostats.
7.Do not mount the control panel on any part of the heating/cooling equipment or ductwork.
8.Do not install control panel where temperatures exceed 158°F (70°C).
CAUTION: Installer must touch a grounded metal object before handling the Aprilaire Zoned Comfort Control panel to avoid potential loss of programs due to static discharge.
1. MOUNT THE CONTROL PANEL
Four holes are provided on the back of the unit for mounting. (See Figure 1)
•Mount indoors using #8 or #10 screws (field supplied).
•Mount in location where the temperature will not exceed 158°F and will not drop below freezing (32°F).
•Do not mount on foundation walls, or on the HVAC equipment or ductwork. These locations can cause the enclosure to become cooler than the surrounding air, which can cause moisture to condense on the enclosure.
