electrical supply. The disconnect switch should be near the
blower and must be capable of being locked by
maintenance personnel
Maintenance personnel must be provided complete control
of the power source.
Moving Parts
All moving parts must have guards to protect personnel. All
PRVS blowers are supplied with vented FRP belt and shaft
guards. Never start a blower without having all safety
guards installed. Check regularly for damaged or missing
guards and do not operate any blower with guards
removed.
Sound
Blowers can generate sound that could be hazardous to
exposed personnel. Appropriate ear protection should be
used by maintenance personnel.
Air Pressure and Suction
Blowers present a hazard from the suction created at the
blower inlet. This suction can draw materials into the
blower where they become high velocity projectiles at the
outlet. Inlets and outlets that are not ducted should be
screened to prevent entry and discharge of solid objects.
PRVS blowers can be supplied with inlet and/or outlet PVC
or stainless steel screens.
View Ports
View Ports to the duct system should never be opened
while the blower is in operation. Serious injury could result
from the effects of air pressure or suction.
Receiving and Inspection
All M.K. Plastics blowers and fans are carefully inspected
before leaving the factory. Compare all components with
the bill of lading or packing list to verify that the proper unit
was received. Check each unit for any damage that may
have occurred in transit:
•
Turn the wheel by hand to ensure it turns freely
and does not bind.
•
Inspect the dampers (if supplied) for free operation
of all moving parts.
•
Record on the Delivery Receipt any visible sign of
damage.
Mishandled units can void the warranty provisions. If units
are damaged in transit, it is the responsibility of the receiver
to make all claims against the carrier. M.K. Plastics will
assist the customer as much as possible; however claims
must be originated at the point of delivery. M.K. Plastics is
not responsible for damages incurred during shipment.
