This questionnaire must be filled out for every rejected compressor during the warranty & goodwill period.
Affected compressors must be inspected according to the methods described in the WIS in terms of delivery rate and oil ejection.
The resulting technical facts are required for filling out this questionnaire.
Both "Oil ejection" test sheets created during the test, act as supporting documents and they must be attached to the completely filled out questionnaire.
The completed form (both "Oil ejection" test sheets " and the completely filled out questionnaire) must now be sent in for inspection as part of submitted warranty and goodwill claims along with the removed compressor.
