NOTE: The letters used in the following instructions refer to Typical Installation on page 7.

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever you see this symbol.

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing the equipment.

1.Turn off power supply to the pump or close upstream master air valve (E).

2.Open all fluid shut off valves (J and L) in the system.

3.Trigger the meter (N) into a waste container to relieve pressure.

4.Open fluid drain valves and leave them open until you are ready to pressurize the system.

Grounding

The equipment must be grounded to reduce the risk of static sparking. Static sparking can cause fumes to ignite or explode. Grounding provides an escape wire for the electric current.

To prevent electric arcing do not allow the conductive metal surfaces on the meter to make contact with any positively charged metal surface, including (but not limited to), the starter solenoid terminal, alternator terminal or battery terminal.

Ground all components in the system:

Pump (F): Follow manufacturer’s recommendations.

Air and fluid supply lines (A, B, K): Only use electri- cally conductive hoses. Check electrical resistance of hoses. If total resistance to ground exceeds 29 meg- ohms, replace hose immediately.

Air compressor: Follow manufacturer’s recommenda- tions.

Fluid supply container: Follow local code.

To maintain grounding continuity when flushing or relieving pressure: hold a metal part of the meter firmly to the side of a grounded metal pail, then trigger the valve.

SDMM8 and SDMP8 Meter (N): When installing the meter leave at least two threads bare when using thread sealant. The bare threads ensure a ground is main- tained.
