Tips for mounting an LCR 600

•Leave the cover assembly fastened to the base to protect the internal components.

•Ensure that the vertical drive shaft from the meter is attached to the pulser drive shafts.

•Before securing the LCR 600 to the meter or mounting bracket, ensure that the counter is visible and the keypad and selector switch can be easily operated.

WARNING

Relieving Internal Pressure

All internal pressure must be relieved to zero pressure before disassembly or inspection of the strainer, vapor eliminator, any valves in the system, the packing gland, and the front or rear covers.

Serious injury or death from fire or explosion could result in performing maintenance on an improperly depressurized and evacuated system.

Relieving Internal Pressure Procedure for LPG and NH3 Meters

Follow these steps:

1.Close the belly valve of the supply tank.

2.Close the valve on the vapor return line.

3.Close the manual valve in the supply line on the inlet side of the meter. If no manual valve exists on the inlet side, consult the truck manufacturer for procedures to depressurize the system.

4.Slowly open the valve/nozzle at the end of the supply line.

5.After product has bled off, close the valve/nozzle at the end of the supply line.

6.Slowly crack the fitting on top of the differential valve to relieve product pressure in the system. Product will drain from the meter system.

7.As product is bleeding from the differential valve, slowly reopen and close the valve/nozzle on the discharge line. Repeat this step until the product stops draining from the differential valve and discharge line valve/nozzle.

8.Leave the discharge line valve/nozzle open while working on the system.
