Engineering Data Model 120ERV
Latent Recovery/Moisture Transfer Core
The cross flow energy recovery core transfers heat and water vapor between the two air
streams. It is easily removed for cleaning and service.
MOTORS AND BLOWERS
Each Air stream has an independent motorized impeller. 3 speed operation 120VAC.
FILTERS
Washable air filters in exhaust and supply air streams.
MOUNTING THE ERV
Four threaded inserts at corners of case designed to accept four reinforced polyester straps
that are supplied with the unit.
CASE
Twenty gauge prepainted galvanized steel (G60) for superior corrosion resistance. Insulated
to prevent exterior condensation.
CONTROLS
Unit is supplied with a remote ERV box which can be conveniently located within 3’ of the
ERV.
ERV System Control
ERV defaults to LOW SPEED when plugged in. HIGH SPEED option is accessible by con-
necting remote controls to designated terminals inside electrical box of ERV.
Standard LOW SPEED SETTING can be increased to medium low. Off (Standby)/Low or
OFF/HIGH speed operation is also available.
DUCT CONNECTIONS
5” duct connections with ‘field’ selectable standard airflow or reverse airflow for limited room
installations.
