Check Solution XT Doors and Latches
Refer to the service manual for adjusting and replacing
the doors.
Solution XT 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 loca-
tion and multiple skid AHUs are fully assembled. After
AHU installation use a channel lock pliers or a screw-
driver 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 Johnson Controls' intention that a shipping wrap-
per be applied to unpainted indoor AHUs for protec-
tion from weather, road dirt, etc. during inland transit.
Remove the wrapper at the time of delivery to allow
for a thorough inspection, both inside and out. Under
no circumstances 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
located 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.
Occasionally, an outdoor Solution XT AHU may be en-
tirely wrapped in plastic, which should not be removed
until the Solution XT AHU is installed, to prevent
damage from job site dirt and various weather condi-
tions. If the Solution XT AHU is covered with plastic,
cut the wrap in the outline of the door(s), and proceed
to access the Solution XT 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 22 on
page 30 through Figure 38 on page 33.
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 Johnson Controls sales rep-
resentative, if there are questions regarding the AHU
weights.
MOVING THE AHU
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) seg-
ments in rear discharge location (end of the AHU), the
AHUs will ship with the top section (hot deck) separat-
ed. 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 12 on page 24,
and raceway lifting lugs as shown in Figure 13 on page
25. Do not use top corner connectors. Use come-a-
longs as shown in Figure 11 on page 24.
