load 12" cartridge filter with a 1" header. The 

manufacturer shall ship the rooftop unit with 12" 

MERV 14 cartridge filter. 

F. 

The filter rack shall be designed to accept a face 

load 12" cartridge filter. The manufacturer shall 

ship the rooftop unit with 12" MERV 16 face load 

cartridge filter. A walk in access section upstream of 

face load filters is required for filter maintenance.

G. 

The filter rack shall be designed to accept a face 

load 12" cartridge filter. The manufacturer shall ship 

the rooftop unit with 12" HEPA face load cartridge 

filter. A walk-in access section upstream of face load 

filters is required for filter maintenance.

2 .18 Outdoor/Return Air Section

A. 

Unit shall be provided with a Metal Mesh pre-filter 

in the outdoor air hood/section to prefilter large 

particulate to prevent early filter clogging.

B. 

Unit shall be provided with a 0–30% Outside Air 

damper. The outdoor air hood shall be factory 

installed and constructed from galvanized steel 

finished with the same durable paint finish as 

the main unit. The hood shall include moisture 

eliminator filters to drain water away from the 

entering air stream. The outside and return air 

dampers shall be sized to handle 100% of the 

supply air volume. The dampers shall be parallel 

blade design. Damper blades shall be gasketed 

with side seals to provide an air leakage rate of 

1.5 cfm/square foot of damper area at 1" differential 

pressure in according with testing defined in AMCA 

500. Control of the dampers shall be by a factory 

installed direct coupled actuator. 

C. 

Unit shall be provided with a 100% Outside Air 

damper. The outdoor air hood shall be factory 

installed and constructed from galvanized steel 

finished with the same durable paint finish as 

the main unit. The hood shall include moisture 

eliminator filters to drain water away from the 

entering air stream. The outside and return air 

dampers shall be sized to handle 100% of the 

supply air volume. The dampers shall be parallel 

blade design. Damper blades shall be gasketed 

with side seals to provide an air leakage rate of 

1.5 cfm/square foot of damper area at 1" differential 

pressure in according with testing defined in AMCA 

500. Control of the dampers shall be by a factory 

installed direct coupled actuator. 

D. 

Unit shall be provided with an outdoor air 

economizer section. The economizer section shall 

include outdoor, return, and exhaust air dampers. 

The economizer operation shall be fully integral 

to the mechanical cooling and allow up to 100% 

of mechanical cooling if needed to maintain the 

cooling discharge air temperature. The outdoor air 

hood shall be factory installed and constructed from 

galvanized steel finished with the same durable 

paint finish as the main unit. The hood shall include 

moisture eliminator filters to drain water away from 

the entering air stream. The outside and return 

air dampers shall be sized to handle 100% of the 

supply air volume. The dampers shall be parallel 

blade design. Damper blades shall be gasketed 

with side seals to provide an air leakage rate of 

1.5 cfm/square foot of damper area at 1" differential 

pressure in according with testing defined in AMCA 

500. Control of the dampers shall be by a factory 

installed direct coupled actuator. 

E. 

Damper actuator shall be fully modulating and spring 

return type. A comparative drybulb control shall be 

provided to sense and compare drybulb in both 

the outdoor and return air streams to determine if 

outdoor air is suitable for “free” cooling. If outdoor air 

is suitable for “free” cooling, the outdoor air dampers 

shall modulate in response to the unit’s temperature 

control system.

F. 

Damper actuator shall be fully modulating and spring 

return type. A comparative enthalpy control shall be 

provided to sense and compare enthalpy in both 

the outdoor and return air streams to determine if 

outdoor air is suitable for “free” cooling. If outdoor air 

is suitable for “free” cooling, the outdoor air dampers 

shall modulate in response to the unit’s temperature 

control system.

G. 

A barometric exhaust damper shall be provided to 

exhaust air out of the unit. A bird screen shall be 

provided to prevent infiltration of rain and foreign 

materials. 

H.  A power closure barometric exhaust damper shall 

be provided to exhaust air out of the back of the 

unit. The actuator will hold the damper shut during 

unoccupied mode. A bird screen shall be provided to 

prevent infiltration of rain and foreign materials. 

I. 

All units must be capable of CO

2

 control. Outside air 

damper position will modulate between the Demand 

Control Ventilation Limit (minimum position setpoint) 

and the Ventilation Limit (maximum non-economizer 

position setpoint) to satisfy the space requirements. 

Damper position will be controlled to the greater of 

the two command signals, either minimum outside 

air flow or space IAQ (CO

2

).

J. 

Provide the units with factory installed, and tested 

thermal dispertion style outdoor air flow measuring 

station.
