that combustion air supply is not affected. Follow the 

heating equipment manufacturer’s requirements and 

the combustion air supply requirements of applicable

fume hoods or collection systems for toxics.

10. When cutting or drilling into wall or ceiling, do not  

damage electrical wiring and other hidden utilities.

To avoid motor bearing damage and noisy and/or 

unbalanced impellers, keep drywall spray, construction 

dust, etc., out of unit.

NOTE: Disconnect Switch and 24V Transformer Standard

Do not remove or disable the wiring interconnection between the 

Overload Relays and the Contactors. Without this interconnection 

the motor(s) will not be protected against overload.

In  2012,  these  ERVs  may  be  ordered  with  new  factory-

installed features including Isolation Dampers and Variable 

Frequency  Drives.  Consult  the  supplemental  Installation
