• The final step is blowing out the dust from the electrical enclosure with the compressed air.
• Turning off power at the circuit breaker and unplugging the communications plug from the top
of the Vortek hoist will make it safe to open up the enclosure.
• Using the same 7/32” hex key, remove the
2 Allen head screws from the top of the
electrical enclosure and swing down
the cover.
• Hint: pushing the cover up at the curved
hinges while swinging the cover down will
help in opening the enclosure.
• Using a low to medium pressure air stream,
gently blow any dirt and dust bunnies from
the ventilation holes from both sides of the
drive inverter.
Note: Safety glasses should be worn during this
procedure.
• Re-install the cover to complete this maintenance portion of the Vortek hoist.
• Last thing to check is the attachment connections for the hoist to the
structural steel.
Check these two 9/16” hex
head bolts for torque
values of 17-20ft/lbs.
Check both sets of clamps.
Check the nuts on the backbone stiffeners for tightness.
