PLEASE NOTE: Our economizer is a low leak, eld installed economizer with the iAIRE patented con-
trols packages and actuator, allowing you to reduce the amount of outside air needed from your rooftop
HVAC system by up to 2/3 and will improve indoor air quality.
This reduction in system operation creates on-going utility savings. Payback on capital equipment costs
with an iAIRE economizer can be realized in fewer than three years. These packages are designed to
work directly on existing rooftop HVAC systems.
These economizers are all low leak and meet the IECC 2015 requirement and are Title 24 compliant by
meeting section 120.2(i) for the required controls and the e󰀩ciency requirements in 140.4(e).

Chassis 5 - Vertical Install
1. Remove return air compartment lter access panel and lower economizer panel of HVAC unit.
Save the screws and the lter access panel, but discard the economizer panel.
2. Slide the economizer up to the HVAC unit and tilt the top of the economizer toward the HVAC unit.
Slide it into the compartment as shown below.
3. At the back of the bottom return opening, under the lter rack on the HVAC unit, there are three
tabs. The front ange of the economizer must slide under these tabs.
4. Once the front ange is under the tabs, lower the economizer until it sits down into the slot on the
back of the economizer and down onto the base rail of the HVAC unit.
5. Be sure the side anges of the power exhaust cabinet are sitting in the slots of the corner posts of
the HVAC unit.
6. Fasten the economizer to the HVAC unit through the holes provided. Use the screws that were
removed from the economizer panel in step 1.
7. At the lter access door opening, reach in and plug the economizer harness into the corresponding
economizer harness in the HVAC unit.
8. Refer to page 5 in IOM-0014 Economizer Controls Installation Manual for installation of the various
sensors and actuators. Connect wires according to the wiring diagram on page 8.
9. Slide the lter access door back into the place above the economizer.
