Installation Guideline

F-420 Meter Installation

Please use the following steps to guide you through the
installation.

1. Flowmeter must be installed in an exact vertical plane to

ensure accuracy.

2. Use PTFE tape (or similar)for the flowmeters threaded

adapters. Acrylic and other exotic plastics cannot
tolerate PVC Glue and/or pipe dope. Even fumes can
cause crazing. If you are installing your flowmeter to a
glued pipe configuration, install flowmeter after all
glued fittings are dried and lines are purged of all
fumes.Never hold the meter with pliers or like tools.

DO NOT OVER-TIGHTEN!

3. Wall, floor and ceiling mounts are to be carefully aligned and sturdy. Wall, floor and ceiling

supports are recommended as needed.

4. Valves - Avoid a system that will impose a sudden burst of flow to the meter. Such a

burst will cause the float to impact the float stop with destructive force. Solenoid valves,
or other quick opening valves cannot be used unless meter is protected against sudden
bursts of flow.

5. Maximum working pressure not to exceed recommended psi at fluid temperature (see

Temperature Vs. Pressure chart).

Caution: Follow these tips to avoid failure

Danger: Wear eye protection when installing or removing

flowmeter.
