Introduction

This article explains how to run and complete a drainage test for ducted ceiling concealed systems. 

This test ensures the drainpipe properly directs condensate to a suitable location. The test differs depending on whether the electrical wiring is already finished.

This article applies to the following systems: 

• Quantum Ultra Ducted Ceiling Concealed (RYB/RYT)

• d: Bucket (adding water through the water inlet)
• e: Drain outlet for maintenance
• f: Refrigerant pipes

Electrical Wiring is Not Finished Yet
