Heat Recovery Ventilator
INTRODUCTION
The Heat Recovery Ventilator (HRV) is used to exchange indoor
stale air with outside fresh air. The HRV unit is equipped with a
special heat recovery core which transfers sensible heat between
the fresh incoming air and stale exhaust air.
It is required to locate the HRV in a conditioned space. Special
attention should be given to condensate drain, duct application,
balancing the HRV, and locating unit for easy access and routine
maintenance. The cross- flow design core allows entering and
leaving air streams to transfer heat energy without mixing.
NOTE: Read the entire instruction manual before starting the
installation.
SAFETY CONSIDERATIONS
Improper installation, adjustment, alteration, service, maintenance,
or use can cause explosion, fire, electrical shock, or other
conditions which may cause death, personal injury or property
damage. Consult a qualified installer, service agency or your
distributor or branch for information or assistance. The qualified
installer or agency must use factory- authorized kits or accessories
when modifying this product. Refer to the individual instructions
packaged with the kits or accessories when installing.
