INTRODUCTION

The ERVBBHA Energy Recovery Ventilator is used to exchange
indoor stale air with outside fresh air. The unit is equipped with a
special energy recovery core which transfers both sensible and
latent heat between the fresh incoming air. The cross- -flow design
core allows entering and leaving air streams to transfer heat energy
without mixing. (See Fig. 2.)
The ERVBBHA is available in 2 sizes with airflow ranges of
60- -148 CFM (28 - - 71 L/s), and 60- -183 CFM (28 - - 89 L/s). The
design of this unit is horizontal. Special attention should be given
to duct application, balancing the ERV, and locating unit for easy
access and routine maintenance.

INSTALLATION CONSIDERATIONS

Inspect Equipment
Move carton to final installation location. Remove ERVBBHA
from carton taking care not to damage unit. Remove all packaging
and inspect unit for damage. Remove parts bag from inside unit.
File claim with shipping company if shipment is damaged or
incomplete. Check to make sure ERV unit matches Fig.1.
Select Location
The ERV should be located in a conditioned space and in close
proximity to a fused power source. It should be easily accessible
for routine maintenance.
If ERV is installed independent of a forced- -air system, unit should
be located near the center of the air distribution system. If ERV is
installed in conjunction with a forced- -air system, unit should be
located next to (or close to) the indoor equipment.
