1. INTRODUCTION

The purpose of this bulletin is to inform users of proper XG Guard usage for the Model XT1 Sprinklers. The XG Guard assemblies

are specifically listed and approved for use on Model XT1 Sprinklers; no other guard assemblies should be used.

WARNING

Viking sprinklers are manufactured and tested to meet the rigid requirements of the approving agency. The sprinklers

are designed to be installed in accordance with recognized installation standards. Deviation from the standards or

any alteration to the sprinkler after it leaves the factory including, but not limited to: unlisted accessories, painting,

plating, coating, or modification, may render the sprinkler inoperative and will automatically nullify the approval and any

guarantee made by The Viking Corporation. Refer to the Authority Having Jurisdiction prior to installation.

2. GENERAL INFORMATION:

A potential product performance issue may exist when listed products are combined with unlisted product(s) that have not been

evaluated together by a recognized approval laboratory. With the development of new products and existing products, it is extremely

important to correctly match a sprinkler with a sprinkler guard. Please refer to the appropriate manufacturer’s technical literature or

call Viking Technical Services at 877-384-5464.
