D.4. Economizers and Fresh Air

Dampers

D.4.1. Economizer Information

ECONOMIZERS - Mechanical devices

used to make the Heating Ventilation and

Air Conditioning (HVAC) unit more efficient

by regulating the return air and outside air.

Economizers for this product come in several

configurations.

The Downflow Economizer

is designed

specifically for units setup in a downflow

configuration. The downflow economizer

fits inside the package unit and sits over the

return-air opening along the bottom of the unit.

All economizers are equipped with horizontal

gear driven blades and a gravity relief damper

(Barometric Relief).

The Horizontal Economizer

is designed

specifically for units setup in a horizontal flow

configuration. The horizontal economizer

utilizes independently actuated return-air and

fresh air dampers to enable the most efficient

handling of air achievable with this platform.

The horizontal economizer also includes an

externally-mounted (to the duct work) gravity

relief damper.

All units with economizers come shipped from

the factory with a parts bag and a separate

document for Economizer Installation &

Operation instructions. Refer to that document

for information on how to install the economizer,

connect the controls, and adjust the airflow.

Accessory economizers purchased separately

will also come with the parts bag and

instructional document.

For reference, the Installation Instructions for

economizers may be found in the parts bag of

the unit for factory installed economizers, in the

box with the field installed economizer, or on the
manufacturer’s website for the product.

Note: Louver protections are optional.

This product will accept both 2” and 4” filters. A new

unit ships with four 2” x 20” x 20” filters. For units

with an economizer, only use 2” filters due to fitment

clearances. To replace filters, follow these steps:
1. Remove “Filter Access” panel.
2. Pull downwards on retainer wire and rotate

upwards to unlock filters.
3. Secure retainer wire in notch.

4. Remove and discard current filters.
5. Install new filters with airflow arrow pointing

towards evaporator coil.
6. Rotate retainer wire downward to original position

and secure in notch.
7. Install “Filter Access” panel.
