2.4 Storage Procedure
NOTE: The following is the recommended storage procedure to retain maximum product integrity during storage. Failure to comply with recommended procedure will void the warranty.
Storage (Less Than One Year)
Operators should be stored in a clean, dry, protected warehouse and should be stored on wooden skids to protect the machined mounting flange. If the operators must be stored outside, they must be covered in polyethylene protection with silica gel crystals to absorb moisture. Input shafts should be rotated every three months to mix lubricant.

4 Installation Instructions
4.1 Safety Precautions
cc |
WARNING: Read this Installation, Operation and Maintenance Manual carefully and completely |
|
before attempting to install, operate, or troubleshoot the Limitorque operator. |
cc |
WARNING: Potential HIGH PRESSURE vessel — be aware of high-pressure hazards associated |
|
with the attached valve or other actuated device when installing or performing maintenance |
|
on the operator. Do not remove the operator mounting bolts from the valve or actuated device |
|
unless the valve or device stem is secured or there is no pressure in the line. |
cc |
WARNING: For maintenance and/or disassembly of the operator while installed on the valve, |
|
ensure that the operator is not under thrust or torque load. If the valve must be left in service, the |
|
valve stem must be locked in such a way as to prevent any movement of the valve stem. |
cc |
WARNING: Do not manually operate the operator with devices other than the installed hand- |
|
wheel. Using force beyond the ratings of the operator and/or using additive force devices such as |
|
cheater bars, wheel wrenches, pipe wrenches, or other devices on the operator handwheel may |
|
cause serious personal injury and/or damage to the operator and valve. |
cc |
WARNING: Do not exceed any design limitations or make modifications to this equipment |
|
without first consulting Limitorque. |
cc |
WARNING: Use of the product must be suspended any time it fails to operate properly. |
aa |
CAUTION: If a motor actuator is driving the manual operator, do not operate the valve under |
|
motor operation without first checking and setting the limit switch setting and checking for |
|
correct motor rotation. |
aa |
CAUTION: Do not use replacement parts that are not genuine Flowserve Limitorque parts, as |
10 |
serious personal injury and/or damage to the operator and valve may result. |
