More than one disconnect switch may be required to de-energize
the equipment for servicing.
Installation work and electrical wiring must be done by qualified
person(s) in accordance with all applicable codes and standards,
including fire-rated construction codes and standards.
When cutting or drilling into wall or ceiling, do not damage elec-
trical wiring and other hidden utilities.
NEVER place a switch where it can be reached from a tub or
shower.
Intended for use with 24 VAC Class 2 power supplies only.
Do not connect loads that exceed the timer’s switch rating.
Confirm sufficient 24 VAC power is available to operate the timer
and the connected loads.

About RenewAire
For over 30 years, RenewAire has been a pioneer in enhancing indoor air quality (IAQ)
in commercial and residential buildings of every size.This is achieved while maximizing
sustainability through our fifth-generation, static-plate, enthalpic-core Energy Recovery
Ventilators (ERVs) that optimize energy efficiency, lower capital costs via load reduction and
decrease operational expenses by minimizing equipment needs, resulting in significant energy
savings. Our ERVs are competitively priced, simple to install, easy to use and maintain and have
a quick payback. They also enjoy the industry’s best warranty with the lowest claims due to
long-term reliability derived from innovative design practices, expert workmanship and Quick
Response Manufacturing (QRM).
As the pioneer of static-plate core technology in North America, RenewAire is the largest ERV
producer in the USA. We’re committed to sustainable manufacturing and lessening our
environmental footprint, and to that end our Waunakee, WI plant is 100% powered by wind
turbines. The facility is also one of the few buildings worldwide to be LEED and Green Globes
certified, as well as having achieved ENERGY STAR Building status. In 2010, RenewAire joined
the Soler & Palau (S&P) Ventilation Group in order to provide direct access to the latest in energy-
efficient air-moving technologies. For more information, visit: renewaire.com
