5.3.3 HAZARDS ASSOCIATED WITH BREAKDOWN OR IGNITION OF LUBRICATION
DANGER
There is a risk associated with the lubrication media breaking down and
resulting in a hazardous fl uid or vapor. There may also be a hazard
associated with the ignition of the lubrication media. Refer to the lubrication
manufacture’s applicable instruction for safety precautions.
5.4 PIPING CONNECTIONS
WARNING
Pipe loading on the blower should be negligible as pipe loading can cause
distortion of the blower. Use proper supports and pipe hangers to assure
that there is no loading.
NOTE
Remove the protective covers from the inlet and outlet ports and inspect for
dirt and foreign material.
Inlet and outlet connections on all blowers are large enough to handle maximum volume with minimum
friction loss. Maintain same diameter piping. Silencers must not be supported by the blower. Stress loads
and bending moments must be avoided.
Be certain all piping is clean internally before connecting to the blower. We recommend placing a 16-mesh
wire screen backed with hardware cloth at or near the inlet connections for the fi rst 50 hours of use until the
system is clean. Make provisions to clean the screen after a few hours of operation and completely discard
it once the system is clean, as it will eventually deteriorate and small pieces going into the blower can cause
serious damage. A horizontal or vertical air fl ow piping confi guration is easily achieved by rearranging the
mounting feet position.
HAZARDS ASSOCIATED WITH HAZARDOUS PROCESS FLUIDS
DANGER
It shall be the responsibility of the installer to ensure that piping is adequate,
sealing between pipe joints is adequate for the process fl uids and proper
process and pressure protection devices are in place. It is also the
responsibility of the installer to assure that process gasses are not vented
in a manner that would be hazardous.
Refer to the manufacturer of the process media to assure that proper safety
precautions are in place.
5.4.1 BLOCKAGE OR RESTRICTION
WARNING
Damage to the blower could occur if there is blockage in the inlet or outlet
ports or piping. Care should be taken when installing the blower to assure
that there are no foreign objects or restrictions in the ports or piping.
