Energy Recovery Ventilation (ERV) Sections

CAUTION
The assembled sections will result in a unit center of
gravity (CG) higher than the horizontal centerline. Exer-
cise proper care when rigging, lifting and transporting.
Units with a high CG will tip over more easily during
installation than those with a lower CG.
RECEIVING AND INSPECTION — Inspect the section
for freight damage upon receipt. Inspect the cassette that is
mounted inside the section. The cassette consists of a frame,
wheel assembly and segments. Verify that the wheel turns
freely by hand (clockwise when viewed from the pulley
side). Report any damage immediately to the freight compa-
ny.
RIGGING AND STACKING — The ERV section sizes
03-17 are shipped fully assembled. These units can be
stacked and unstacked, as required, during installation by
following the same procedure as for larger units de-
scribed below.
NOTE: If an ERV section (size 08-17) does not fit through
a doorway, it may be taken apart by removing the top of the
section frame. This will expose the ERV wheel; take pre-
cautions not to damage the wheel while moving the section.
Once the section is in place, put the top of the section frame
back on.
The ERV section sizes 21-30 are shipped unstacked due
to shipping height limitations. The lower sections are all as-
sembled on baserails and all fastened together on a single
skid. The upper sections are on a separate skid and fastened
together. Rigging and setting the lower sections is the same
as for a standard 39M indoor base unit. Refer to the Rigging
Information label on the unit.
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 the 4 lifting brackets holding the row of sections
to the skid.
2. Separate each section one at a time and install brackets
at each corner using the screws provided. Be careful
not to strip out the holes in the section frame. Lift and
set the section on top of the lower sections.
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
outward to each end of the unit.
Repeat this process for the remaining ERV sections.
ERV WHEEL MOTOR WIRING — All ERV wheel motors
have stripped back power leads. For units with 3-phase
wheel motors, install and route the proper wire type and size
directly to the motor junction box provided.
For units with single-phase wheel motors connections
must be made in a separate, field-installed junction box.
This junction box must be installed in the ERV section close
to the motor. The ERV motors are VFD ready.
Refer to Table 43 for motor electrical data.

Marine Lights and Convenience Outlets —
Marine lights can be factory-installed with or without a GFCI
(ground fault circuit interrupter) convenience outlet. See Fig.
151 and 152 for a typical marine light with a convenience out-
let and Fig. 153 and 154 for a typical marine light without a
convenience outlet. To connect power to the light, route the
supply voltage to either the base of the light (interior) or to the
switch/convenience outlet assembly (exterior).
The factory installs a low-wattage LED bulb. However, if an
incandescent bulb is installed the existing wiring can handle
the increased amp draw.
