The Seaward Primetest 200 or equivalent should be used to test the electrical insulation of a Class ll
appliance; it indicates any electrical leakage.
Procedure for use:
1. Remove the pre-filter cover and pre-filter on the product.
2. Connect the red lead from the tester to the shaft of screwdriver via a crocodile clip.
3. Locate the screwdriver through the filter housing grille, onto the motor fan.
4. Plug the product directly into the tester.
5. Ensure the mains switch of the product to be tested is in the ON position.
6. Set the range selector to the double insulated symbol.
7. Press the 'test' button on the tester. Record the reading.
A reading of > 2MΩ is accepted. 2MΩ is the minimal legal requirement. A reading of below 2MΩ is
not considered safe and further investigation and rectification must be made before the product is used.
The following components must be visually inspected:
• Cable rewind assembly, both internal and external
• Switch
• Motor
• Carbon build up in the motor housing
If you cannot repair a product with an insulation test reading of below 2MΩ
you must
inform the customer that it 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!
ON
The following test 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. This is vital to avoid any possibilities of personal injury to the end user.
Test the socket outlet using the 3-pin test unit to ensure that the socket is correctly wired and earthed.
Ensure that at all times during the
repair and testing of products that
customers, pets, children and you are
not exposed to any Live electrical supply.

Cable rewind:
Live (points 1-3) = 1Ωmax.
Neutral (points 2-6) = 1Ωmax.
Switch (points 3-4) = 1Ωmax.
Motor assy (points 5-7) = 7Ωapprox.

contain a lock mechanism.
The mechanism will need
to be pressed before
separation from the male
terminal can occur.
