Lifebreath 120ERV installation manual Engineering Data Model RNC120F, HRV System Control

Engineering Data Model RNC120F

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

Each Air stream has an independent motorized impeller. 3 speed operation 120VAC

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

Fan defrost system. Fresh air motor turns off and Exhaust motor switches to high speed to defrost core.

CASE

Twenty gauge prepainted galvanized steel (G60) for superior corrosion resistance. Insulated to prevent exterior condensation. Drain connection 1 - 1/2" (12 mm) OD.

CONTROLS

Unit is supplied with a remote HRV control box which can be conveniently located within 3’-0” of the HRV.

HRV System Control

HRV defaults to LOW SPEED when plugged in. HIGH SPEED option is accessible by connecting remote controls to designated terminals inside electrical box of HRV.

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.
