- The appliance/system has not been taken apart or repaired by anyone other than qualified service personnel.
- The system has been serviced as recommended in the manufacturer’s instructions.

CHNZ cannot accept responsibility, in any situation, for products installed in remote or locations outside 80kms from the point of purchase.
Products are not covered under warranty when undue stress is caused by poor system design and installation.

The warranty part must returned to CHNZ with the completed Returns Form.

be issued.
Should a product be returned and is found not within the warranty period or not a manufacturing fault then the part will be invoiced.
For further questions or information, please contact CHNZ. We are here to assist you with any problems and/or concerns that may arise.
