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 savings. 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 resistance.
Insulated to prevent exterior condensation. Drain connections 2 - 1/2" (12 mm) OD.
Door balancing ports.
CONTROLS
ControlAir 15 - Standby/ON mode, 20 ON/ 40 OFF mode, 20 ON/40 Recirculation
mode, Recirculation mode (each mode has 5 speeds). Control pad can be removed
from HRV and remotely mounted.

All units conform to
CSA and UL standards.
The ECM motor produces a tone that some may
find objectionable. We recommend the
installation of the optional 99-SILENCER6 on the
‘Stale Air from Inside’ and ‘Fresh Air to Inside’
ducts.
ATTENTION
*Sensible Efficiency – thermal **Latent Efficiency – moisture
Note: Effectiveness - based on temp. differential between the 2 airstreams
Efficiency – takes into account all power inputs
