SPECIAL INFORMATION

DANGER !

Before opening any Viking pump liquid

chamber (pumping chamber, reservoir,

relief valve adjusting cap fitting, etc.)

Be sure:
1. That any pressure in the chamber has

been completely vented through the

suction or discharge lines or other

appropriate openings or connections.

2. That the driving means (motor,

turbine, engine, etc.) has been “locked

out” or made non-operational so that

it cannot be started while work is

being done on pump.

3. That you know what liquid the

pump has been handling and the

precautions necessary to safely

handle the liquid. Obtain a material

safety data sheet (MSDS) for the

liquid to be sure these precautions

are understood.

Failure to follow above listed

precautionary measures may result in

serious injury or death.
