NOTE TO ENERGY RATERS INSTALLATION HVI rated performance of this ERV is not representative of the actual CFM/watt performance in the actual application due to test protocol of the laboratory rating test. Actual ERV CFM/watt performance with the triangular openings connected to a location under negative static pressure will significantly improve. For example at medium speed with the connection location at - 0.2- in. w.c. and with +0.1- in. w.c. duct connection static, a typical measurement is 1.

A13280 Fig. 7 - J- Hook Installation 2. Position the cabinet at the location where it will be installed. Hook the remaining J- hook mounting bracket into the J- hook that is installed on the ERV and use this to mark the mounting hole locations for the J- hook on the furnace or duct. Alternatively, locate the top of the J- hook 32- 3/4- in. higher than where the bottom of the ERV cabinet will lie (3/4- in. higher than where the top of the ERV cabinet will lie). A13279 Fig.

5. Reaching through the triangular cutouts on the non- attached side, use a marker to trace the triangular cut out locations on the duct or furnace cabinet. Exhaust Baffle Installation (Furnace Cabinet Installations Only) If the ERV is mounted directly to the furnace cabinet, the exhaust baffle provided in the carton is used to prevent short cycling the fresh- air supply to the stale- air exhaust. (If a replacement is needed, order Part No. 5429 from Replacement Components.

Install the green ground wire to the ground screw on the blower housing. Refer to the furnace installation manual for locations of the EAC- 1 and EAC- 2 terminals. Connect the black wire to the line voltage terminal (EAC- 1) and the white wire to the line voltage – neutral terminal (EAC- 2). Plug the power cord into the receptacle of the ERV to determine how much cable to leave outside the furnace cabinet. Make sure the power cord inside the furnace cabinet cannot reach any moving part.
