Greenheck Exhaust Weatherhood, ERV, ERH, ERCH and APEX (462844) - Manual

Unpack, inspect, and verify receipt of the correct weatherhood pieces for your unit. Some energy
recovery units will require two exhaust weatherhoods. The exhaust weatherhood provided with
your energy recovery unit is based on the exhaust blower model size.
To determine the weatherhood you have received, measure the exhaust blower scroll (see drawing
below) and locate the corresponding “Blower Model” from the table.
Then refer to the Weatherhood Parts List table on the back of this document. Locate the Blower
Model and compare the parts listed with the weatherhood you have received.
Once the parts are verified, continue with the weatherhood assembly procedures on Page 2.
