IV - Re quire ments
When installed, the unit must be electrically wired and
grounded in accordance with local codes or, in the
absence of local codes, with the current National Electric
Code, ANSI/NFPA No. 70.
V - Ap pli ca tion
Energy Recovery Ventilators (ERV) are used with rooftop
units. These ventilators conserve energy by mixing
warmer air with cooler air in the following manner:
Re cov ery Wheel Mode
The Recovery Wheel mode is accomplished by two
blowers providing continuous exhaust of stale indoor air
and replacement by equal amount of outdoor air. Energy
recovery is achieved by slowly rotating the energy
recovery wheel within the cassette frame work. In winter,
the ERV adsorbs heat and moisture from the exhaust air
stream during one half of a complete rotation and gives
them back to the cold, drier intake air supply during the
other half rotation. In summer, the process is automatically
reversed. Heat and moisture are absorbed from incoming
intake air supply and transferred to the exhaust air stream.
This process allows outdoor air ventilation rates to be
increased by factors of three or more without additional
energy penalty or increase in size of heating or air
conditioning systems.

VII - In stal la tion
1. Remove and discard the rooftop unit horizontal return
air access panels, hoods and/or power exhaust
equipment.
2. Remove carton from ERV and remove individual
wrapped assemblies.
3. At the rooftop unit remove filter access panel and door
below it (discard).
4. Then insert balancing damper over bottom return air
opening.
5. Attach adapter panel over balancing damper panel
with removed screws. Verify platform support rail is
attached to adapter panel.

supports. Then slide telescoping part of leg out of
guide from the top. Tip ERV unit forward reinserting
into bottom of guide having attached flat foot under
unit.
7. Place screws back into side of adjustable leg supports,
adjustment will need to be made later when unit is put
into position.
8. Position with ERV open face pointed toward adapter
panel.
9. Attach provided gasketing material (1
divider deck to adapter panel.
10. Attach provided gasketing material (
(perimeter) of ERV unit to prevent air leakage.
11. Pick up the ERV unit and lower onto platform support
rail aligning hole in the front edge of ¾" flange with
