RIGGING AND STACKING

The ERV section sizes 03-14 are shipped stacked (fully assem-
bled) and size 17 with 4, 6, or 8 in. baserails are shipped
stacked (fully assembled). These units can be stacked and un-
stacked, as required, during installation by following the same
procedure as for larger units described below.
The ERV section sizes 17 with 10 in. baserails and sizes 21-61
are shipped unstacked due to shipping height limitations. The
lower sections are all assembled on baserails and shipped sepa-
rately. The upper sections are also assembled on baserails and
shipped separately. Rigging and setting the lower sections is
the same as for a standard 39MN indoor or 39MW outdoor
base unit. Refer to the Rigging Information label on the unit.
For sizes 36-61, the ERV wheel bypass sections are shipped
stacked. upper section must be removed from lower section before
installation.
CAUTION
The upper sections MUST be rigged and lifted one at a time
or injury or unit damage may occur.
Rigging and lifting upper sections:
1. Use all lifting brackets provided on the baserail section.
2. Lift and carefully set the section on top of the lower sec-
tions using guide pins to align and avoid damage to gasket.
For sizes 21-30, upper sections should be stacked onto the
lower sections starting with the section upstream and
downstream of the wheel section, and then moving out-
ward to each end of the unit.
Repeat this process for the remaining ERV sections.
