Electrical safety testing
Ensure that at all times during the repair and testing of products
that customers, children, pets and you are not exposed to any
Live electrical supply.
Insulation test
The following tests must be performed prior to
and upon completion of all repairs to Dyson
floorcare products and before any functional
checks.
You must ensure that a full visual inspection of
the product is completed prior to repair.
Test results
An insulation test reading of >2 MW
is acceptable.
A reading of below 2 MWis not considered
safe and will require replacement of the
chassis and motor assembly.
The Seaward Primetest 200 (or equivalent)
should be used to test the electrical
insulation of a Class 11 appliance; it
indicates any electrical leakage.
Insulation test point:
These tests are vital to avoid any possibility
of personal injury to the end user.
If you cannot repair a product with an
insulation test reading of below 2MW
you must inform the customer that the
product is unsafe to use.
Please inform the customer of the
required actions to repair the product
(including the charge structure).
If the product is left un-repaired please
indicate on your paperwork/hand held
device that the product is electrically
unsafe and attach a ‘WARNING:
product electrically unsafe’ sticker in
a visable location on the product.
