Ul Recommended High Voltage Test; Ground Continuity Test; Using A Servicing Platform - Bissell ProHeat 2X 8920 Series Service Center Manual

UL RECOMMENDED HIGH VOLTAGE TEST

In keeping with UL standards, a high voltage test should be performed on a vacuum or
deep cleaner any time the unit is in for repair, particularly when the motor or other
electrical components have been replaced. High voltage testing is done for the safety of
the customer. By applying an over-voltage between "live" parts and various metal
portions of the machine that are exposed to wear, you proof-test the entire machine
against grounds or shorts that could cause inconvenience, fires, or personal injury. High
voltage testing is also a quality control measure. The possible future failure in the
insulation of any portion of the unit, whether due to workmanship, components, or
materials, will be detected by this procedure prior to return of the unit back to the
customer.
The normal test parameters are 1000 volts for one minute. There must be no indication of
dielectric breakdown at the uppermost values. After the unit is completely assembled, the
high voltage test required is the power cord to terminals in plug with the product switch
on "on" position. This test can be accomplished with any commercially available test
equipment offered for this purpose. The following testers are recommended:
Associated Research - Model 4025 or 4050 AJ
Slaughter - Model Series 2306 or 2307
Beckman Ind. (Rosemont) Model P-9A

GROUND CONTINUITY TEST

This test is performed to determine that grounding continuity exists between the
grounding blade of the lower supply cord plug and the motor. This test should be
performed any time electrical connections are disturbed. Any suitable indicating device -
ohmmeter, battery/buzzer combination or the like may be used to determine compliance.
Contact points are the ground terminal and the plug to the shaft of the vacuum motor and
the heater body.

USING A SERVICING PLATFORM

Begin by placing the unit on a servicing platform. Servicing Platform should fit securely
under the unit and raise its wheels off the workbench surface.
