ENGINEERING DATA
THERMALLY CONDUCTIVE, PATENTED ALUMINUM CORE
The cross-flow heat recovery core transfers heat between the two
airstreams. It is easily removed for cleaning or service.
MOTORS AND BLOWERS
High effficiency electronic comutated ECM motor for maximum energy sav-
ings. Each air stream has one centrifugal blower. 5 speed fan operation
driven by one double shaft motor. 120 VAC, 1.0 Amps.
FILTERS
Washable air filters in exhaust and supply air streams.
MOUNTING THE HRV
Four threaded inserts at corners of case designed to accept four reinforced
polyester straps that are supplied with the unit.
DEFROST
Recirculating damper defrost system.
DEHUMIDISTAT
Adjustable Internal Dehumidistat.
CASE
Twenty gauge prepainted galvanized steel (G60) for superior corrosion resis-
tance. Insulated to prevent exterior condensation. Drain connections 2 -
1/2" (12 mm) OD.
CONTROLS
ControlAir 15 - Standby/ON mode, 20 ON/ 40 OFF mode, 20 ON/40
