Set Up the Indoor Unit Condensate Piping Connections for Quantum Ultra Ceiling Cassette (CYT-24) systemsUpdated 2 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.

Install the 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°. 

Connection Procedure

• Connect the transparent flexible hose to the PVC drain pipe. 
• Apply PVC adhesive to the connection point between the drain pipe and flexible hose to ensure a watertight seal. 
• Apply the adhesive approximately 1-½ inches (38 mm) from the end of the PVC pipe, then insert it into the flexible hose. 
• Allow at least 10 minutes for the adhesive to cure. Do not apply pressure to the joint during the drying period. 

Heat Insulation

• Wrap the entire length of the flexible hose carefully with the provided heat insulation material. Start from the flexible hose and continue to the indoor unit connection. 
• Ensure that there are no gaps or exposed sections that could cause condensation. 
• Use additional insulation material if necessary to fully cover all piping and connections. 

Upward Drainage Installation

• The maximum vertical rose of the drainage pipe should not exceed 30 inches (762 mm). 
• Maintain a horizontal extension from the indoor unit drain outlet of less than 4 inches (102 mm) before rise. 

After the Installation is Completed

After the installation is finished, check the condensate drain line for leaks and proper drainage. If a condensate pump has been installed, check it to ensure proper operation. Pour water into the drain pan through the inspection port to confirm flow.

Note: A condensate pump is not provided with the system.
