THERMALLY CONDUCTIVE, PATENTED ALUMINUM CORE: The

cross-flow heat recovery core transfers heat between the two air

streams. It is easily removed for cleaning or service.
MOTORS AND BLOWERS: Each air stream has one centrifugal blower

driven by a common PSC motor. 120 VAC, 1.4 Amps.
FILTERS: Washable air filters in exhaust and supply air streams.
MOUNTING THE HRV: Four 10-24 5/8” threaded inserts at corners of

case designed to accept four PVC reinforced polyester straps that are sup-

plied with the unit.
DEFROST: Damper defrost system; defrosts automatically as the out-

door temperature falls.
CASE: Twenty gauge prepainted galvanized steel (G60) for superior

corrosion resistance. Insulated to prevent exterior condensation. Drain

connections 2 - 1/2” (12 mm) OD.
WEIGHT: 71 lbs. (32.5 kg) SHIPPING WEIGHT 73 lbs. (33.5 kg)
CONTROLS: Basic ON/OFF control is maintained with the 3 foot,

120VAC, 3-prong electrical cord providing power to the HRV.
HRV DEFAULTS TO LOW SPEED when plugged in. HIGH SPEED op-

tion is accessible by connecting remote, low voltage, 2-wire controls (up

to 10) or (up to four 28 884 -20 minute fan timers) to designated terminals

inside electrical box of HRV.
STANDARD SPEED SETTING can be increased by manipulating jump-

ers in electrical box. OFF (Standby) /LOW or OFF/HIGH speed opera-

tion also available by manipulating jumpers.
OFF, LOW and HIGH speeds are all remotely controllable when an op-

tional 28 883 Dehumidistat Ventilation Control (DVC) is connected to the

HRV’s electrical box.
