Understanding the Ductwork Best Practices for Under-Bench RV SystemsUpdated 4 days ago

Introduction

Learn the best practices for installing ductwork with your Under-Bench RV Inverter Packaged Heat Pump Air Conditioner. 

Ductwork Best Practices

Construct the air distribution ducting using standard trade parts (not included with the system).

We recommend using an aluminum-core cardboard pipe with an external PVC covering for air conditioning.

Ensure the nominal inner diameter is up to 2-3/8 inches (60 mm) and the outer diameter is up to 2-1/2 inches (63.5 mm).

The tapered air outlet allows you to join ventilation ducts simply by pressing them together.

Connect the ducts using either the outlet on the coil side or the side outlet. To use the side outlet, remove the guard and close the front holes.

Connect the ventilation pipes by pressing them into the tapered hole of the air outlet. You can attach the pipes to either the coil-side outlet or the side outlet.

A compatible Pioneer air distribution kit is sold here. 

For optimal efficiency, it is advised to:

• Route the air ducts as short and flat as possible. 
• Do not exceed 16 feet (4.9 m) in duct length. 
• Avoid laying the air ducts near any sources of heat. 
• Avoid condensation on the ducting by insulating the pipes with insulation material.
