Check each unit on arrival to ensure all major compo-
nents, boxes and crates are received, undamaged, and
compared to the packing list.
Damage
Before unloading, inspect each unit for any visible
signs of damage while still on the trailer or rail car.
Report any damage or signs of possible damage to the
transportation company immediately for the compa-
ny's inspection.
Johnson Controls will not be responsible
for any damage or loss of parts in ship-
ment or at job site.
Shortage
After inspecting the assemblies, all containers should
be opened and contents checked against the packing
list. Any material shortage should be reported to John-
son Controls immediately. Refer to
Shipping Damage
Claims (Form 50.15-NM
).
Storage
Units are shipped without export crating unless crating
has been specified on the sales order. Observe the fol-
lowing precautions, if the unit is to be stored prior to
installation:
If the temperature is outside of the 40°-
110°F (4°-43°C) range, make sure the
water boxes and VSD heat exchanger are
completely drained of all liquid, which
could freeze. Make sure the condenser
and evaporator tubes are completely dry.
The VSD coolant must be drained and
replaced with anti-freeze solution.
• The chiller must be blocked under the end sheets.
• Ensure that all openings, such as water connec-
tions, are securely capped.
• Store the unit in a location where:
• It will NOT be exposed to ambient air tem-
peratures exceeding 110°F (43°C).
• There is minimal activity to limit the risk of
accidental physical damage.
• It is protected from rain or mist. Cover with a
tarp, if the unit will be located outside.
• If the unit is stored longer than six months, follow
the requirements from
Long-Term Storage Peri-
odic Checklist and Logs for YR, YS, and YVWA
Screw Chillers
(
Form 50.20-NM9
).
• Inspect the unit periodically during storage.
• To prevent inadvertent operation of the pressure
relief devices, the unit must not be steam cleaned.
