Create the Recirculation Air Opening for Under-Bench RV SystemsUpdated 2 days ago

Introduction

This article explains how to create the recirculation air opening for Under-Bench RV Inverter Packaged Heat Pump Air Conditioners. 

Create the Final Cutout Opening for Recirculation Air

Create an additional hole in the compartment where the system is installed. This is done to permit recirculation of the internal air. 

It's best to locate the cutout near the front of the machine. If the opening cannot be made near the machine, ensure that the air flow is not obstructed by anything. Then, create an air duct between the opening and machine. 

The cutout should be roughly 50 in² in size. The hole will be closed with a grille supplied. 

Only allow the recirculated air to enter the compartment from within the passenger section. If the air entering this opening is from the outside, the performance of the machine will diminish. 

Finally, install the condensation drain tubes provided with the system onto the bottom parts.
