long-term Storage
Long-term storage is considered any period beyond
six (6) months from date of shipment. If long-term
storage is anticipated,
contact the Johnson Controls
Sales representative for the proper instructions and
requirements for long-term storage.
It is mandatory
that a detailed record be maintained during this long-
term period, such as, but not limited to: proper sealing
of the cabinet, rotation of the blowers and bearings,
and protection of all motors from moisture.
Refer to
Form 50.20-NM3
“
Long Term Storage Requirement -
Field Preparation” and Form 50.20-CL3
“
Long Term
Storage Periodic Checklist and Logs
”
, copies of which
is included in this section.
Preventive Maintenance Prior to Long Term
Storage
The following precautions should be taken prior to
extended storage:
• Fan and motor bearings are to be greased per the
manufacturer’s specifications.
• Motors and sheaves must be protected from
free moisture or high humidity. This may be
accomplished by 1) spraying components with
an anti-rust solution (P/N 026-37707-000) or 2)
disconnecting the belts and wrapping the sheaves
and motor and sealing them with plastic. Insert a
desiccant to absorb moisture that may penetrate
the plastic protection.
• The fan motor windings should be megged at
this time and recorded for comparison prior to
placing in service.
• If the fan housing was supplied with a drain con
-
nection, this plug should be removed to prevent
moisture from accumulating in this portion of the
fan during storage.
long-term storage is considered to be
any period beyond six (6) months from
date of shipment. If long-term storage
is anticipated, contact Johnson Con-
trols Sales representative at time of
order entry for the proper instructions
and requirements for long-term stor-
age. Refer to Form 50.20-NM3.
Periodic Fan Check
On a monthly basis, the fan and motor should be
rotated several times to replenish the bearing surfaces
with fresh grease
.
The fan impeller should be left at approximately 180
degrees from that of the previous month to prevent the
belts from taking a set position.
It will be the responsibility of the cus-
tomer to submit a monthly log sheet
(MS577) showing the condition of the
unit and noting any discrepancies. A
copy of the log sheet should be sent
to the Johnson Controls Office, attn.:
Sales Representative.
Failure to perform the long-term stor-
age requirements will void the war-
ranty.
