4.7 Fire / smoke in the appliance
4.8 Requirements
4.9 Testing selected components (casing mounted)
Flames and/or smoke may come out of the oven when switching it on after service/repair.
This can be caused by a defective electrical component or electrical connections (wiring)
that have been refitted incorrectly.
The equipment required for testing the appliance is as follows.
Portable Appliance Tester (P.A.T.)
Digital Multi-Meter (D.M.M.)
Megger / similar 500 V d. c. resistance meter
Microwave detection / leakage meter
Temperature reader
Continuity meter
Door Spacer Kit
Microwave safe 600 ml glass beaker
Microwave safe 2 litre container
Switch off the oven.
Disconnect/isolate the oven from the electrical supply.
Keep the oven door closed to stifle any flames.
While testing with a Portable Appliance Tester (PAT) is not an automatic requirement for
the Commercial High Speed Oven models, the following notice is to advise on this testing
in addition to the following instructions as deemed necessary.
If the customer requires PAT testing of our equipment we suggest this is limited to a)
earth continuity and b) insulation resistance (measured at ~ 500 V DC). All Commercial
High Speed Ovens are classified as CLASS 1 for the purpose of testing.
Should it still be deemed necessary by the customer to perform an Earth Leakage test,
the following advice should be adhered to. Note that not all PATs are capable of just
measuring the leakage or allow you to set a pass limit and therefore may not be
appropriate for this test.
