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.
