PROTECTIVE SPRINKLER SHIELDS AND CAPS

General Handling and Storage:

Many Viking sprinklers are available with a plastic protective cap or shield temporarily covering the operating elements. The snap-

on shields and caps are factory installed and are intended to help protect the operating elements from mechanical damage during 

shipping, storage, and installation. NOTE: It is still necessary to follow the care and handling instructions on the appropriate sprin-

kler technical data sheets* when installing sprinklers with bulb shields or caps.

WHEN TO REMOVE THE SHIELDS AND CAPS:

NOTE: SHIELDS AND CAPS MUST BE REMOVED FROM SPRINKLERS BEFORE PLACING THE SYSTEM IN SERVICE!

Remove the shield or cap from the sprinkler only after checking all of the following:

• 

The sprinkler has been installed*.

• 

The wall or ceiling finish work is completed where the sprinkler is installed and there no longer is a potential for mechanical damage 

to the sprinkler operating elements.

SHIELDS AND CAPS MUST BE REMOVED FROM SPRINKLERS BEFORE PLACING THE SYSTEM IN SERVICE!

HOW TO REMOVE SHIELDS AND CAPS:

No tools are necessary to remove the shields or caps from sprinklers. DO NOT use any sharp objects to remove them! 

Take care 

not to cause mechanical damage to sprinklers when removing the shields or caps.

 When removing caps from fusible ele-

ment sprinklers, use care to prevent dislodging ejector springs or damaging fusible elements. NOTE: Squeezing the sprinkler cap 

excessively could damage sprinkler fusible elements.

• 

To remove the shield, simply pull the ends of the shield apart where it is snapped together. Refer to Figure 1.

• 

To remove the cap, turn it slightly and pull it off the sprinkler. Refer to Figures 2 and 3.

Refer to the current sprinkler technical data page to determine the correct sprinkler wrench for the model of sprinkler used.

Never install sprinklers that have been dropped, damaged, or exposed to temperatures in excess of the maximum ambient
temperature allowed.

* Refer to the appropriate current technical data pages for complete care, handling, and installation instructions. Data 

pages are included with each shipment from Viking or Viking distributors. They can also be found on the Web site at www.
