SECTION 3 - HANDLING, STORAGE, AND INSTALLATION
Long Term
Long term storage is more than six months from the 
date of shipment. If long term storage is anticipated, 
contact the Johnson Controls sales representative for 
the proper instructions and requirements.
It is mandatory that a detailed record be maintained 
during this long term period, such as, but not limited 
to the following:
• Proper sealing of the cabinet,
• Rotation of the blowers and bearings, and
• Protection of all motors from moisture.
Refer to Long Term Storage Requirement - Field Prep-
aration (Form 50.20-NM3) and Long Term Storage 
Periodic Checklist and Logs (Form 50.20-CL3) for 
more information.
Failure to fulfill the long term storage 
requirements will void the warranty.
Receiver’s Responsibility
The receiver is solely responsible for noting the 
freight bill and filling out the freight claims IMME-
DIATELY.  In addition, the receiver must:
•  Note the visible damage on the signed and 
 dated bill of lading with a request that the 
  carrier inspect the damage within 72 hours 
  of notification.
•  Remove the shipping wrapper, and replace it 
 with a tarp or similar protective covering. Any 
 concealed damage reported after 15 days will 
  compromise a claim settlement.
•  Request inspections by telephone or in person, 
  but confirm in writing. If assistance is needed 
 with the claim process, contact a Johnson 
  Controls sales representative and refer to the 
  shipping damage form.
INSPECTION, DAMAGE, AND SHORTAGE 
Check the AHU shipment on arrival to make sure that 
all major pieces, boxes, and crates are received. Check 
each AHU on the trailer or rail car when received, be-
fore unloading, for any visible signs of damage. Report 
any damage or signs of possible damage to the trans-
portation company immediately for its inspection.
After inspecting the AHU for damage, open all con-
tainers and check the contents against the packing list. 
Report any material shortage to Johnson Controls im-
mediately. 
JOHNSON CONTROLS WILL NOT BE 
RESPONSIBLE  FOR  ANY  DAMAGE 
OR LOSS OF PARTS IN SHIPMENT OR 
AT JOB SITE. Refer to Shipping Damage 
Claims (Form 50.15-NM).
Preventive Maintenance Prior to Long Term 
Storage
Take the following precautions prior to extended stor-
age:
• Grease the fan and motor bearings per the manu-
facturer’sspecications.
• Protect the motors and sheaves from free moisture 
or high humidity, which may be accomplished by:
• Spraying components with an anti-rust solu-
tion (P/N 026-37707-000).
• Disconnecting the belts. Wrapping the 
sheaves and motor and sealing them with 
plastic. Inserting a desiccant to absorb mois-
ture that may penetrate the plastic protection.
• Meg the fan motor windings and record for com-
parison prior to placing the AHU in service.
• If the fan housing was supplied with a drain con-
nection, remove the plug to prevent moisture from 
accumulating in this part of the fan during storage.
Periodic Fan Check 
On a monthly basis, perform the following tasks:
• Rotate the fan and motor several times to replen-
ish the bearing surfaces with fresh grease.
• Turn the fan impeller 180° from the previous 
month's position to prevent the belts from taking 
a set position.
Monthly Log Sheet
It is the customer's responsibility to submit a monthly 
log sheet from the Long Term Storage Periodic Check-
list and Logs (Form 50.20-CL3) that shows the condi-
tion of the AHU and to note any discrepancies. Send 
a copy of the log sheet to the Johnson Controls Field 
Service Office for its records.
