DataTrak Operation

See DataTrak manual 313840 for all DataTrak information and parts, including detailed oper- ation instructions.

Pump Shutdown

At the end of the work shift and before you check, adjust, clean or repair the system, fol- low Pressure Relief Procedure, page 14.

Maintenance

Maintenance Schedule

Establish a preventive maintenance schedule, based on the pump’s service history. Sched- uled maintenance is especially important to prevent spills or leakage due to diaphragm failure.

Lubrication

The pump is lubricated at the factory. It is designed to require no further lubrication for the life of the pump.

Maintenance

Tighten Threaded Connections

Before each use, check all hoses for wear or damage and replace as necessary. Check to be sure all threaded connections are tight and leak-free. Check fasteners. Tighten or retorque as necessary. Although pump use varies, a general guideline is to retorque fasteners every two months. See Torque Instructions, page 16.

Flushing and Storage

•Flush before fluid can dry in the equipment, at the end of the day, before storing, and before repairing equipment.

•Flush at the lowest pressure possible. Check connectors for leaks and tighten as necessary.

•Flush with a fluid that is compatible with the fluid being dispensed and the equipment wetted parts.

Flush the pump often enough to prevent the fluid you are pumping from drying or freezing in the pump and damaging it. Use a compati- ble solvent.

Always flush the pump and relieve the pres- sure before storing it for any length of time.
