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.
