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.
