INSTALLATION INSTRUCTIONS
CAUTION: Installation of Model 730 is not recommended for continuous pressure applications. Faulty installation could
result in an improperly functioning device. For in-line continuous pressure applications, the Model 735 shall be used. Note:
The Model 735 is for non-approval applications.
The installer should be sure the proper device has been selected for the particular installation.
WILKINS Laboratory Faucet Vacuum Breakers are designed for installations on laboratory faucets, where a potential health
hazard exists due to back siphonage of contaminated water from the sink or other apparatus.
Proper performance depends upon following these installation instructions and prevailing governmental and industry
standards and codes. Failure to do so releases WILKINS of any liability that it might otherwise have with respect to that
device.
