Set Up the Indoor Unit Condensate Piping Connections for Quantum Ultra Ceiling Cassette (CYT-24) systemsUpdated 5 hours ago

Introduction

This article explains how to set up the indoor unit condensate piping connections for Quantum Ultra Ceiling Cassette (CYT-24) systems. 

Drain Pipe and Insulation Material Requirements

• Drain Pipe: Polyvinyl chloride (PVC) pipe with an 1-¼ inch outer diameter (32 mm). 
• Heat Insulation: Foamed polyethylene insulation with a minimum thickness of ⅜ inch (10 mm). 

Notes

• Insulate all drain piping and connections to the indoor unit to prevent dew formation and dripping. 
• Maintain a continuous downward slope of more than ¼ inch per feet (minimum slope ratio of 1/50) with no dips, sags, or reverse slopes. 
• Install support straps or brackets every 5-6.5 feet (1.5-2 m) along horizontal runs to main proper slope and prevent sagging. 
• Keep the horizontal pipe length under 65 feet (20 m).
• Maintain a gap of approximately ⅜ inch (10 mm) between parallel pipes if installed side-by-side.
• Follow the diagrams below for correct drainage pipe routing and support methods. 

Install a Flexible Hose

• Measure the diameter of the hard pipe using a pipe cutter, then adjust the joining angle as needed. 
• Extend the flexible hose to the required length without excessive deformation as shown below:
• Secure the flexible hose firmly using the provided hose band.
• Install the flexible hose in an horizontal orientation to ensure proper drainage. The maximum bending angle is 45°.
