OPERATION INSTRUCTIONS
WARNING:
 Never operate the meter with the plastic cover removed. The cover protects the meter from damage
due to impact. Meters are sealed in the factory to keep moisture and dirt away.
 Flush the lines before you install this equipment in the system to prevent line contamination, or it can
cause equipment malfunction or damaged.
 To reduce the risk of a serious bodily injury, including fluid injection, never exceed the maximum working
pressure of the control valve you are using or of the lowest rated component in your system.
1. PRESSURE RELIEF PROCEDURE
WARNING: Skin injection hazard: The equipment stays pressurized until pressure is manually relieved.
To reduce the risk of serious injury from pressurized fluid, fluid from the valve or splashing fluid, follow this
procedure whenever you:
 Are instructed to relieve pressure
 Check, clean or service any system equipment
 Install or clean dispensing devices
(1) Pressure relief procedure
①. Turn off the power supply to the pump.
②. Hold a metal part of the control valve firmly to a grounded metal waste container and point the valve
outlet toward the waste container, then trigger the control valve to relieve the fluid pressure.
