SECTION 3 - HANDLING, STORAGE, AND INSTALLATION

Check Doors and Latches

Refer to the service manual for adjusting and replacing
the doors.
AHU doors are shipped with metal shipping spacers
glued onto the edges of each door. They are located
on three edges of each door. The spacers should be
left in place until the AHU is placed in its final location
and multiple skid AHUs are fully assembled. After AHU
installation use a channel lock pliers or a screwdriver
to remove the spacers. Do not damage the metal door
panel. Slight impressions left on the door gasket by the
spacers will rebound in approximately a week.

Indoor AHUs

It is PACE's intention that a shipping wrapper be ap-
plied to unpainted indoor AHUs for protection from
weather, road dirt, etc. during inland transit.Remove
the wrapper at the time of delivery to allow for a thor-
ough inspection, both inside and out. Under no circum-
stances should outdoor storage be used.

Outdoor AHUs

Generally, outdoor AHUs are not fully wrapped. Ex-
posed openings will be covered for protection from
weather, road dirt, etc. during inland transit. Conduct
a thorough inspection, inside and out, at the time of
delivery.
Access - All AHU doors have a small clip, which is lo-
cated on the door frame, and crosses over the edge of
the door. This clip is a safety device to prevent injury
when the AHU is operating. Remove the clip to inspect
the AHU, and replace it when inspection is completed.
Form PA102.20-N1
Occasionally, an outdoor AHU may be entirely wrapped
in plastic, which should not be removed until the AHU
is installed, to prevent damage from job site dirt and
various weather conditions. If the AHU is covered
with plastic, cut the wrap in the outline of the door(s),
and proceed to access the AHU using the information
(above). Close the cut with duct tape.

Shipped Loose Parts

Check the packing list, which notes the number and
types of parts, for non-mounted shipped loose parts in
all segments of the AHU. Report shortages within 10
days after receipt of the order. For more information
about the shipped loose parts, refer to Figure 52 on
page 43 through Figure 70 on page 46.

LIFTING WEIGHTS

AHU section weights are furnished on the job submit-
tal form. Due to the variance in weight of each AHU
design, it is not possible to list AHU weights in these
instructions. Refer to the job submittal form when se-
lecting a crane for rigging and figuring out roof weight
loads. Weights can also be found on skid ID label for
each section. Contact a PACE sales representative, if
there are questions regarding the AHU weights.

MOVING THE AHU

LD16574
Prior to moving the AHU, make sure that the installa-
tion site is suitable for installing the AHU, and is easily
capable of supporting the weight of the AHU and all
associated services.

RIGGING

Some AHUs are shipped completely assembled. When
large AHUs are ordered with multi-zone (MZ) segments
in rear discharge location (end of the AHU), the AHUs
will ship with the top section (hot deck) separated. In
these cases, the complete MZ damper assembly (hot
and cold decks) will ship loose.
All lifting points must be used to avoid
personal injury, death, or damage to the
equipment.
Use all lifting lugs to avoid damage to the AHU. If the
AHU is not equipped with lifting lugs, use bottom cor-
ner connectors as shown in Figure 9 on page 22,
and raceway lifting lugs as shown in Figure 10 on page
23. Do not use top corner connectors. Use come-a-
longs as shown in Figure 8 on page 22.
