  NOTE: Use of paper frame not recommended

VENTILATION DAMPERS

• Check that the equipment complies with all applicable building codes, laws, and regulations for its intended use prior to installation

Motorized Damper w/ Controller (AVADAMP1)

• Utilizes a ventilation air control module that is field programmable to assist with meeting ASHRAE 62.2 requirements
• Once programmed with values for ventilation air amounts, the control module opens the damper in response to thermostat inputs and monitors the run time
• Upon meeting the ventilation air needs, the control module will close the damper until the start of the next cycle
• If, during an observation period it is determined that thermostat operation alone may not provide the desired ventilation air, the control module can independently operate the unit’s indoor blower, in continuous fan mode, and open  the damper to aid in providing ventilation air needs

Motorized Damper w/ Field-Supplied Relay (AVADAMP2)

• Opens ventilation air damper during indoor blower operation and closes during blower off periods
• Requires field-supplied and installed current sensing relay to detect indoor blower operation

• Units are individually controlled with conventional 24V thermostat
• Thermostat must be capable of:
• Single stage cooling and single stage heating (3 and 5 kW single stage electric heat)
• Single stage cooling and two stage heating (7 and 10 kW two stage electric heat)
• Refer to Unit Electrical and Physical Data table for additional details

UNIT ELECTRICAL AND PHYSICAL DATA (208/230 Volt – 1 Phase – 60HZ)1

1. Acceptable voltage range: 197 – 253V
2. MCA = Minimum Circuit Ampacity
3. MOCP = Maximum Over Current Protection
4. SCCR = Short Circuit Current Rating; refer to SCCR Accessory table, up to 200kA
   NOTE: Units are rated at 208/230V, but MOCP & MCA values are calculated at 240V
   NOTE: The 7.2 and 10 kW heats strips offer a W1 and W2 thermostat connection. Taking advantage of the two heat strip circuits requires a 2-stage thermostat (W1 for electric heat stage 1 and W2 for electric heat stage 2). If a single  stage thermostat is used, “pigtail” W1 and W2 wires together when connecting the thermostat wires at the unit.

UNIT DIMENSIONS (IN.)

• Dimension B represents the height of the optional front return air duct opening

• Provisions must be made to properly drain condensate from the primary and secondary drain pans.

MINIMUM CLEARANCES

Accessibility Clearances
The front of the unit must be accessible for service. A minimum clearance of 30” in front of unit is required for service.
