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.
