Overflow Protection

  • The indoor drain pan overflow switch monitors the condensate level in the primary drain pan
  • Prevents unit from running if water is sensed

Secondary Drain Pan

  • The polypropylene wall sleeve base is specifically designed to direct rainwater out of the building and in the event of any restriction in the primary drain will act as a redundant overflow protection

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

  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
  5. Circuits 1 and 2 are independent sets of power wires being run to the unit, each backed by an independent circuit breaker. Units with dual circuits use Circuit 2 exclusively to power electric heaters. Refer to the wiring diagram for additional details.
    • 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 3-stage thermostat (Y for heat pump, W1 for electric heat stage 1, and W2 for electric heat stage 2). If a 2-stage thermostat is used, “pigtail” W1 and W2 wires together when connecting the thermostat wires at the unit.

BLOWER PERFORMANCE

  • Performance-based on factory-provided washable filter installed in the unit.
  • If a higher resistance filter is field installed in the unit, the added resistance must be included in the external static pressure and must not exceed 0.5 in. w.c. including ductwork
  • Refer to Factory Filter Size and Pressure Drop table for additional details

BLOWER PERFORMANCE CONTINUED

  • Performance-based on factory-provided washable filter installed in the unit.
  • If a higher resistance filter is field installed in the unit, the added resistance must be included in the external static pressure and must not exceed 0.5 in. w.c. including ductwork
  • Refer to Factory Filter Size and Pressure Drop table for additional details
