SAFETY PRECAUTIONS
CAUTION: When using PVC pipe or any static enhancing material
for exhaust piping, make provisions to safeguard against arcing
from static electricity. Arcing can ignite oil vapor that may be
present.
CAUTION: The built-in anti-suckback valve is not positive action;
do not use it as a system check valve. Do not depend on the anti-
suckback valve to prevent pump oil from migrating through the
inlet into the system when the pump is shut down.
CAUTION: Do not use this pump in oxygen service. Oxygen service
is defined as any application which has a process gas that is 20% or
more oxygen.
CAUTION: After the electrical connection has been made, but before
the pump is filled with oil, the rotation of the motor must be checked.
Open the inlet port, jog the motor briefly to make sure rotation is cor-
rect. If it runs backwards and if wired three phase power, reverse any
two leads of the three at the power connection.
CAUTION: Keep the oil fill plug tight as pressure in the exhaust box
could cause bodily injury if the plug is blown out. Do not fill/add the
pump with oil through the exhaust/inlet ports as there is danger of
breaking vanes!
CAUTION: Do not add oil while pump is running since hot oil may
escape through the oil fill port..
CAUTION: When changing the oil and filters, it may be necessary to
flush the pump to remove any build-up of degraded oil from the
pump. Reduced oil flow, especially through the radiator or cooling
coil, can cause mechanical damage or extreme overheating, which
could cause oil vapor to ignite.
