Viking Flexible Sprinkler Drop Assemblies are manufactured and tested to meet the latest rigid requirements of the approving
agencies. They are designed and tested to be installed in accordance with the Approved and Listed installation instructions as
provided with the product and the recognized installation standards. Deviations from these standards or any alterations to the sup-
port system or sprinkler after leaving the factory including, but not limited to painting, plating, coating or modification may render
the sprinkler inoperative or the support system non-compliant, automatically nullifying the approvals and any guarantee made by
The Viking Corporation. The use of certain types of sprinklers may be limited due to occupancy and hazard. Refer to the Authority
Having Jurisdiction prior to installation.
For complete installation instructions for this product, please refer to the Viking Flex Drop Installation and Design Manual, Form
No. F_112107.
NOTE: Keep sprinklers with protective shields or caps contained within the shields or caps during installation and testing, and any
time the sprinkler is shipped or handled.
The sprinklers are factory installed onto the outlet reducer fittings along with the outlet reducer support bracket and are pressure
tested.
