Before opening any viking pump liquid chamber (pumping chamber, res-
ervoir, relief valve adjusting cap fitting etc.) Be sure:
1. That any pressure in chamber has been completely vented through
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 seri-
ous injury or death.
