Refer to Table 1 for voltage limitations and Table 9 on
page 27 for airflow and entering air/ambient condi-
tions limitations.
If the variable air volume (VAV) boxes in
the conditioned space have hydronic heat-
ing coils installed, it is the responsibility of
the installing contractor to take appropri-
ate measures to protect the hydronic coils
against low unit supply air temperatures
that could result in the freeze up and rup-
ture of the coils.
UNIT INSPECTION
Immediately upon receiving the unit, it should be
inspected for possible damage, which may have oc-
curred during transit. If damage is evident, it should
be noted in the carrier’s freight bill. A written request
for inspection by the carrier’s agent should be made at
once. See Shipping Damage Claims (Form 50.15-NM)

To ensure warranty coverage, this equip-
ment must be commissioned and serviced
by an authorized Johnson Controls service
mechanic or a qualiîš¿ed service person
experienced in packaged rooftop instal-
lation. Installation must comply with all
applicable codes, particularly in regard to
electrical wiring and other safety elements
such as relief valves, HP cutout settings,
design working pressures, and ventilation
requirements consistent with the amount
and type of refrigerant charge.
Lethal voltages exist within the control
panels. Before servicing, open and tag all
disconnect switches.
