These instructions are intended as a general guide and do
not supersede local codes in any way. Authorities having

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.
