IS-TK-DL

Installation

The Watts TK-DL Computerized Backfl ow Tester

 is an advanced piece of test equipment designed to make pressure and differ-

ential gauges obsolete in the testing of backfl ow assemblies. Two solid-state, high-resolution pressure transducers provide the inter-
face to the computer. With 32K of memory, battery back up, 48 character super-twist display, 16 function keyboard and high-effi cien-
cy thermal printer, the TK-DL is equipped to provide real time data handling and the outputs required to test, validate and certify every 
backfl ow assembly. (See operating manual for details).  The TK-DL allows you to download your test results into a personal computer 
for permanent storage. In addition, the TK-DL menu driven software program allows for customizing of printed header and footer.

GENERAL INFORMATION
Before connecting hoses to tester, be sure to fl ush test cocks on backfl ow assembly.

CAUTION:  To avoid freeze damage to the test kit, it should be stored in a dry warm area when not in use.
