Connect the Condensate Drain for Vertex Ducted Central Split (DYC-18) SystemsUpdated 13 days ago

Introduction

This article explains how to connect the condensate drain for Vertex Ducted Central Split (DYC-18) systems. 

Do not operate the system without a condensate drain. 

For specific requirements, consult local codes. 

Steps

1. Insulate the drainage pipeline to prevent damage caused by condensate formed on the outer surface of the pipeline. 
2.  When connecting the drain connector to the drain pan, use a thin layer of PTFE paste, silicone, or PTEF.
3. Install a 3-inch elbow on the main drainage pipe as close as possible to the unit. Make sure that the top of the elbow is lower than the joint of the drain pan, allowing the drain pan to drain completely. 
4. Extend the auxiliary drainage pipes to positions where condensate can be easily seen. 
5. Plug the unused drain connector with the plug in the parts package provided with the equipment. Use a thin layer of silicone, Teflon paste, or Teflon tape to form a waterproof seal.
6. Tighten the drain connector by hand. Do not over-tighten. Tight fittings will crack the pipe connection on the drain pan. 
7. After installation, test the condensate drain pan and drainpipe. Pour water in the drain pan, enough to fill the drain traps and pipes. Confirm that the drain pan completely drains water, no leakage is found in the drainpipe fittings, and water discharges from the main drainpipe terminal. 

Notes 

• Ensure that the drainpipe will not block the inlet in front of the device. The minimum clearance required for the removal and maintenance of the filter screen, coil, or fan is 24 inches (610 mm). 
• Make sure that the machine is placed horizontally or slightly inclined to the main drain outlet, allowing water to completely drain from the machine. 
• Do not reduce the drainpipe size to less than the connection size provided on the condensate drain pan. 
• All horizonal drainpipes must be inclined downward at a slope of at least 1/8 inch per foot to ensure proper drainage. 
• Do not connect the condensate drain line to the closed or open sewage pipe. Drain the condensate to an open drainpipe or a safe outdoor area. 
• Ensure that there are necessary preparations to disconnect and clean the main drainage pipe. 
• If the condensed water begins flowing out from the auxiliary drainpipe, the homeowner should pay attention to possible problems.
